Introduction

Precision environmental control may be defined as the

simultaneous control of air temperature, humidity,

distribution and cleanliness on a continual, around-the-clock

basis.

Conventional building or ‘comfort’ systems, as they are

called, are not designed for this 24-hour, year-round usage;

they lack the ability to provide the precision and reliability or

‘close control‘ that is so critical to many applications.

All units are built in accordance with European directives

98/37/CE (89/392/CEE; 91/368/CEE; 93/68/CEE),

89/336/CEE; 73/23/CEE. The Liebert Air Conditioning

Quality System is approved by LRQA in accordance with the

standards UNI EN ISO 9001: 1994.

Each unit is supplied complete with a Test Certificate and

Declaration of Conformity.

All Mini Tower units carry the “CE” mark and fully comply

with European Directives concerning mechanical, electrical

and electromagnetic safety.

Liebert technology and energy

efficiency

Liebert has become a world leader in precision environmental

control systems by providing maximum energy efficiency

without compromising precision and reliability.

Liebert takes a no-compromise approach to environmental

control system design. All enhancements to energy efficiency

are designed to reduce operating time of key components.

This is accomplished by taking advantage of alternate sources

of cooling when available or, by reducing compressor work

load when the heat load in the critical space is lower.

Applications

The Mini Tower unit is ideally suited for precision close

control of the following types of environment:

� Data centres

� Telecommunications

� Industrial applications

� Office environments

System types

The Mini Tower is available in a number of configurations:

Air cooled

2 SLE MT TDM E.3_r1 (10/99)


Standard features - all models

General

The Mini Tower series comprises both direct expansion units

and chilled water units. Cooling capacities range from 4 to 11

kW. Direct expansion units are equipped with compliant

scroll compressors. The design of the scroll compressor,

ensures a constant refrigerant pressure, thus improving

reliability, energy consumption and sound emission.

The Mini Towers compact design, facilitates a minimum unit

footprint, allowing the unit to be installed in very confined

areas, the unit is fully serviceable from the front.

Access/maintenance

Routine maintenance access to refrigerant circuit

components, the compressor, liquid reservoir, thermal

expansion valve, sight glass, filter dryer etc. is available

through the front panel of the unit. Service access to the air

filter is also through the unit front panel.

All other components of the machine, the fan, humidifier,

electric panel, electronic controller PCB, electric reheats etc.

are accessible through the front and grille panels.

Customer connections to the refrigerant circuit (hot gas and

liquid line), mains power supply, humidifier water supply and

condensate drain lines are located in the lower right-hand-side

of the unit.

Cabinet

The cabinet is manufactured from primed and treated steel, it

is then degreased and painted in RAL 9018 using dry powder

epoxy resin paint (the return air grille is finished in NCS 3502

coloured paint). The paint finish is easily cleaned and is hard

wearing to give maximum protection. The unit has removable

panels which give access to all internal components from the

front of the unit. The panels are insulated with 12mm, 30

kg/m3 density foam which reduces noise emission and heat

loss. The foam is a self-extinguishing material in compliance

with the following standards: ASTM D 1992, MVSS302,

UL94 Class 0.

A safety microswitch is fitted to the front panel of the unit.

The microswitch deactivates the unit if the front panel is

removed.

The edges of the panels are fitted with seals to prevent air loss

and to keep noise levels to an absolute minimum.

Filter section

The guaranteed efficiency is EU3, (Eurovent EU4/5 (30%

efficiency), equivalent to G3 - CEN Standard). An optional

EU4 filter (G4) is available on request.

The air filter is mounted on the face of the evaporator coil and

is easily accessed/replaced by removing the front panel. The

filter is made of open-cell foam and is designed to minimise

the air pressure drop while maintaining maximum filter

efficiency.

Fan and motor assembly

The unit is fitted with a direct-drive, double-inlet forward-

curved, galvanized-steel, centrifugal fan. The fan impeller is

statically and dynamically balanced and equipped with

sealed-for-l ife bearings. The fan is mounted on

vibration-absorbing rubber supports to reduce vibration

transmission between the fan and the unit frame. This

vibration attenuation helps to keep noise emission to a

minimum.

The fan motor is a single-phase, 5-speed motor complete with

thermal overload protection. Each speed of the motor

produces a different airflow through the unit, refer to the

Technical Data section for specific model/airflow data.

Each unit is wired for two different airflows, a cooling airflow

and a lower, dehumidification airflow. The controller will

switch the unit to the lower airf low during the

dehumidification cycle.

Electric reheat

The single-stage, three element reheats are of rigid,

fin-tubular design that have extended operational life. The

reheat has ample capacity to maintain room dry-bulb

conditions during a system call for dehumidification. The

low-watt density, phase balanced, electrically enclosed

elements are surrounded by the tube and fins, reducing sheath

temperatures and eliminating ionisation.

Reheat control is of the ON-OFF type. The reheat is provided

with a manual reset, reheat safety thermostat, to disable the

reheat in the event of high temperature.

Standard features - all models (continued)

Microprocessor controls

The Microface environmental control system is

microprocessor based and can be programmed to match the

unique needs of any application. The processor integrates the

separate mechanical and electrical components into a

‘state-of-the-art’ conditioned space support system that

controls and monitors temperature, humidity, air flow and air

cleanliness.

The control system offers a tailored and well proven advance

in reliability and control flexibility allowing the unit to

modify its performance in response to changing critical space

conditions.

The controller allows local monitoring and programming of

the following room conditions:

� Temperature (oC)

� Temperature setpoint (5.0oC – 40.0oC in steps of 0.1 oC)

� Temperature sensitivity (1.0oC - 10oC in steps of 0.1 oC)

� Humidity (%RH)

� Humidity setpoint (20%RH - 80%RH in steps of 1%)

� Humidity sensitivity (5%RH - 20%RH in steps of 1%)

The parameters are enunciated using symbols and text on an

LCD display. Normal operating modes are indicated by

symbols on the display. Alarm conditions activate a visual

indicator.

The following alarms are standard:

� High temperature

� Low temperature

� Fan failure

� High pressure alarm – (compressorised systems only)

� Low pressure alarm - (compressorised systems only)

� Electrical reheat high temperature

� Memory failure

� Common alarm

Other alarms are also available when the relevant option is

ordered with the unit (e.g. if a humidifier is ordered with the

unit, the High Humidity, Low Humidity etc. alarms are

enabled). For a full list of all the options and alarms available

with the Microface controller, refer to the Microface

Controller Operation Manual (P/N SLE MF OM).

The controller also incorporates a sequential auto-restart

timer, allowing field adjustable time delays to be applied to

unit restart after a power loss (or other shutdown). The timers

allow multiple units to be restarted while limiting

instantaneous inrush current.

Electrical panel

The electric panel is located at the top-front of the unit in an

airtight compartment. The electrical panel contains the

MCB’s, contactors, transformer, controller PCB and

overload relays etc. Each high voltage system component is

provided with a separate over-current protective device. All

high-voltage components are touch protected by means of a

plastic cover. Electrical design is in accordance with UNI /

EN 60204-1.

All models are supplied as standard for operation at

400V/3ph/50 Hz.

Models TS04A, TS06A, TSF6A, TS07C and TS11C can be

supplied for 230 V/1ph/50 Hz operation to special order.

Packaging

As standard, the units are wrapped in plastic film to protect

painted surfaces, enclosed in a cardboard box and mounted on

a wooden pallet.

On request, for sea transport etc., the units can be packed in

wooden crates or cases complete with silicon desiccant.

Warranty clauses

The warranty does not cover any damage or malfunction of

the unit which may occur during or as a result of operating the

unit outside of the specified application limits.

Liebert does not accept responsibility for any damage caused

by improper use of the product.

4 SLE MT TDM E.3_r1 (10/99)



Refrigerant circuit - dx models

Each unit in the range has a single refrigerant circuit. The

circuit consists of a compressor, a thermal expansion valve, a

liquid line sight glass, a filter dryer, an evaporator coil and

high and low pressure switches.

Liebert recommends the installation of a non-return valve

(supplied as an option, on request) on the liquid line from the

condenser, to protect the compressor from unexpected

refrigerant migration. All low temperature parts of the

refrigerant circuit are insulated as standard.

Compressors

The fully hermetic compliant scroll compressor incorporates

several safety features for protection during normal and the

occasional abnormal operating conditions. They are:

� Self resetting overloads to sense excessive currents and

temperatures.

� An internal pressure relief valve which limits discharge

pressure to protect mechanical parts.

� Motor insulation that is resistant to chemical attack.

� Rubber mounting to ensure reduced compressor noise and

vibration.

Schraeder connections are fitted to the unit for service access.

Refrigerant

R22 HCFC is the standard refrigerant used in the Mini Tower

range. An optional “Green” refrigerant, R407C is available to

special order. In this case the compressor is supplied with

ester oil instead of mineral oil. Air cooled units are shipped

with a nitrogen holding charge.

Evaporator coil

The evaporator coil is constructed from copper tubes with

aluminium fins to ensure maximum heat transfer. It is

designed to maximise the available surface area resulting in

low face velocities, low internal air pressure drops and the

high sensible heat ratios. A corrosion resistant drain pan is

provided on all models.

Filter-dryer

Liquid line filter-dryers ensure a clean, moisture-free

refrigerant system for extended component life. The filter

drier is suitable for use with standard R22 and optional “Zero

ODP” refrigerant R407C.

Expansion valve

The externally equalised, adjustable, thermostatic expansion

valve smoothly controls refrigerant flow during varying

indoor heat loads and outdoor ambient temperatures by

controlling evaporator superheat.

Safety controls

Each compressor has a manual-reset high pressure switch for

high pressure protection and a high pressure alarm circuit to

warn of high system pressures, allowing corrective action to

be taken before a significant loss of temperature control

occurs.

The low pressure switch is auto-resetting and detects low

pressure conditions such as loss of refrigerant charge.

The pressure switch calibration values are shown in the

Installation, Operation & Maintenance Manual supplied with

the machine.

Packaged air-cooled models

Air cooled condensers

A matching Liebert air cooled condenser with fan speed

control should be ordered with the unit. The range includes

condensers with axial fans and centrifugal fans. Details of

standard condenser selections for 32oC ambient are provided

in this manual, full technical details of all condensers for all

outdoor ambients are available in the Condenser Technical

Data Manual, (P/N SLE CD TDM).

Note: Condenser selections/performances for each outdoor

ambient are based on calculated data. The actual selection of

a condenser should always be verified on the basis of the

specific working conditions on each site.

Water/glycol cooled models

Water/glycol-cooled Mini Tower units are fitted with a high

pressure plate heat exchanger and a 2-way water regulating

valve (rated at 1030kPa (150psi)) to maintain head pressure.

Plate heat exchanger

The compact brazed plate heat exchanger consists of a

number of parallel stainless steel pressed plates, the pressing

pattern being inverted on alternate plates. In this way, the

ridges on adjoining plates form contact points and the

refrigerant and fluid move in contra-flow through alternate

channels. The plate heat exchanger is designed to operate at a

maximum working pressure of 30 bar (3000 kPa)

(factory-tested to 40 bar (4000 kPa)).

The units operate with mains water, cooling tower water or

water in a closed circuit with an external drycooler.

When operating in a closed circuit, it may be necessary

(depending on outside temperatures) to add mono-ethylene

glycol to prevent the water freezing in winter, refer to the unit

Installation Manual for applicable percentages.

A pump is used to circulate water (water/glycol) through the

unit (not supplied by Liebert).

If mains water or tower water is used, it is recommended to fit

a mechanical filter on the water line to protect the plate heat

exchanger against possible impurities contained in the water

(for plate heat exchanger cleaning, refer to the Installation

Manual).

Note: Water cooled units may not be suitable for some open

cooling tower applications as good water quality is essential.

Contact Liebert Applications Engineering for details.

Water regulating valve

A 2-way water regulating valve is fitted as standard and is

designed to operate with fluid working pressures of 10.1 bar

(1010 kPa). The valve operates with a maximum fluid

temperature of 77 oC.

Drycooler

A matched Liebert drycooler should be ordered with the unit.

The range includes condensers with axial fans and centrifugal

fans. Details of standard drycooler selections for 32oC

ambient are provided in this manual, full technical details of

all drycoolers for all outdoor ambients are available in the

Drycooler Technical Data Manual, (P/N SLE DC TDM).

Note: Drycooler selections/performances for each outdoor

ambient are based on calculated data. The actual selection of

a drycooler should always be verified on the basis of the

specific working conditions on each site.

powder epoxy resin paint. The paint finish is easily cleaned

and is hard wearing. The cabinet has been designed

specifically for outdoor applications, all materials, fittings

and components have been selected to provide maximum

weather protection, durability and security (vandal-proof

cabinet). The unit has removable panels (a special key is

required) which give access to all internal components. The

condenser air inlet is through the rear of the unit and

discharges through the front. A metal safety grid prevents

accidental contact with the fan and the coil. The compressor is

located in the side of the Condensing unit, separated from the

airstream.

Condenser coil

The condenser coil is manufactured from refrigeration quality

copper tubes with mechanically bonded aluminium fins, and

is vertically mounted.

Fan/motor assembly

complete with internal thermal protection. The fan motor is

controlled by a pressure switch to maintain a steady

condensing temperature.

Fan speed control

A factory fitted solid state fan speed controller is installed to

maintain the refrigerant condensing pressure. The controller

varies airflow through the condenser to maintain a constant

pressure. The advantages of fan speed control are two-fold.

Higher reliability of the system due to less starts/stops of the

compressor and a lower noise level because the fan is running

at a lower speed, mainly during night-time.

to the internal sensor) connected to the unit controller.

The sensor can be installed up to 20m from the unit and

generates an alarm if the temperature or the relative humidity

exceeds one of the 4 user-set limits:

� High Temperature Limit

(Adjustable from 10°C to 50°C)

� Low Temperature Limit

(Adjustable from 0°C to 30°C)

� High Humidity Limit

(Adjustable from 30% to 99%)

� Low Humidity Limit

(Adjustable from 10% to 70%).

Floorstand

Floorstands are available in a range of heights: 230mm,

305mm, 380mm, 460mm, 530mm and 610mm. Each height

of floorstand is adjustable over a � 38mm range. The

floorstands permit installation and connection of the unit

prior to installation of the raised floor.

Turning vane

A factory installed turning vane may be specified to direct the

air as required within the floorstand.

Optional features - all systems (continued)

Hiromatic graphic*

The Hiromatic Graphic sets even higher standards in

purpose-designed control systems for precis ion

air-conditioning. It simultaneously monitors the critical space

and signals alarms either locally or remotely. The graphics

screen displays all the major parameters, including symbolic

representation of unit functions, such as heating, cooling etc.;

in addition temperature and humidity variations with time can

be presented graphically on the screen. All diagnostic

procedures, including the checking and calibration of input

and output signals, and of the microprocessor itself, can be run

from the front panel

Features

� Backlit LCD graphics display

� User interface via pushkeys

� Battery-backed clock for date/time and real time functions

� Password control for setpoints, unit/control setup and

service functions

� Graphics display of temperature and humidity over a 24

hour period

The Hiromatic Graphic is specifically designed for group

management of a number of individual units although it can

be used in stand-alone applications. Due to its large graphical

display area, combined with exceptional contrast, it allows

the user to move around easily within the network of

connected unit controllers (up to max. 16). It is possible to

control/adjust each connected units operations from a single

point.

The controller is menu-driven and user menu’s are available

in 10 languages. The controller records the last 120 “events”

(Alarms, Warnings etc.) occurring in the system along with a

“Graphic Data Record” for each connected unit. The Graphic

Data Record displays the temperature and humidity readings

from each unit for the last 24 hours (stored since the last

start-up of the unit).

The Hiromatic Graphic controls date and time functions using

them as operating information for the customer and as a

reference whenever a status change occurs, logging the status

change in the “Status Report”. Details of the event which

occurred, the date and time at which the event occurred are

also stored. Using buffered RAM, the Hiromatic also stores

the operating hours of each component (compressor, fan,

electric heaters, humidifier etc.) for each connected unit.

A feature uniquely available with the Hiromatic controller is

“Sleep Mode” Sleep Mode allows units to be programmed to

switch on and off at different times of the day, and on different

days of the week.

*: The Hiromatic Graphic is supplied in a wall-mounted box

for remote installation.

BEMS Interface

The Hiromatic Graphic allows units on a network to be

integrated with the Hirolink Communications Bus when an

RS422 card is installed at the back of Hiromatic. Hiromatic

can control up to 8 Microface units in this configuration and

communicate the relevant data to Hirolink.

Hirolink works as a communications manager between the

Hiromatic Graphic and Microface units and industry standard

field busses and protocols used in Building Management

Systems such as Mod-Bus, J-Bus, Satchwell, etc.

Note: For full details of the controller, refer to the Hiromatic

Graphics Controller Manual, (P/N SLE HG OM).

Special packaging

Where the unit is to be transported by sea or in other cases

where heavy duty packaging is required, special crating is

available.

This can consist of either a wooden crate over the standard

carboard/bubble wrap packaging or the entire unit can be

encased in a wooden box.

Alternative refrigerant R407C

An optional “green” refrigerant, R407C can be supplied with

all compressorised models.

The compressor is filled with a special ester oil required for

R407C. Air cooled units are filled ex-factory with a holding

charge of dry nitrogen. Water and glycol units are charged

with R407C.

Optional features - all systems (continued)

Special colour

Where required by the installation, the unit can be supplied in

any RAL colour. Minimum order quantities may apply,

consult Liebert Applications Engineering.

Extended warranty

The standard, parts-only, warranty is 15 months from the unit

ship date. This can be extended to 21, 27 or 39 months as an

option.

Flow switch

The flow switch is available as an option with chilled water

units. It is fitted as standard on the chilled water inlet line but

can be fitted on the bypass-leg (3-way valves) or between the

valve and the coil, if required by the application.

The switch is of the paddle type and is complete with volt-free

contacts. It can be wired to activate an alarm and/or shut down

the unit should the chilled water supply be interrupted.

Epoxy coated fins

- condensing unit

If the condensing unit is to be installed in a potentially

corrosive environment or close to salt water, epoxy/acrylic

coated fins are available to maximise the operating life of the

condenser coil. Capacity will be derated, contact Liebert

Applications Engineering for specific details.
