Contents

Legend The following legends are used throughout this manual:

IntroductionThe Ducted Mini Split system from SKM consists of RX (a high efficiency- TOP discharge Air Cooled Condensing Unit); matching with DDP (a low noise, ceiling suspended indoor fan coil unit). This split systems are ideally suited for apartments, houses, offices, shops, small residences, and in small commercial establishments.

SKM ducted mini split system are available in different models covering 1.5 TR to 5 TR (6 kW to 18 kW) at nominal AHRI condition, which make them ideally suited for a very small foot print for space saving and a pleasant exterior appearance.

SKM ducted mini split system are designed in accordance with ESMA, ESTIDAMA & MEW regulations.

SKM ducted mini split units are suitable to operate in a wide range of ambient temperature. (Minimum outdoor operating ambient in cooling mode is 55°F (13°C), maximum is 125°F (52°C).

SKM ducted mini split units are internally wired and all that required to be done on site is ducting, refrigerant piping, power supply and suitable room thermostat installation and field wiring, which reduces the installation work and consequently keeps to a minimum cost.

SKM provides qualified service and stock of replacement parts in all major cities of the G.C.C. countries, Egypt, Jordan, and Pakistan. See back cover for details or call SKM.

Outdoor Unit - RX

• Design - Outdoor condensing units are ideal for rooftop or ground installation. Units have a pleasant exterior appearance and have a very small footprint for space saving installation.

• High efficiency Coils - inner groove tubes; mechanically bonded to hi-efficiency aluminium fins to match for a maximum efficiency.

• Hermetic Scroll Compressor - High efficiency hermetically sealed scroll type compressor located on engineered mounts for safe, quiet and vibration free operation.Compresssors are selected for reliability, power efficiency & provided with crankcase heater.

• Cabinet Construction - Heavy gauge zinc clad steel, latest technology electrostatic powder baked finish to ensure a long lasting, durable cabinet.

• Fan Motor – Condenser fan is propeller type with aluminium alloy blades and directly driven by electric motors.

• Brass Service Valves – Factory installed service valve with sweat connections to provide quick and accurate installation for start-up and servicing.

• Ease of Service and Installation – Designed to make servicing easier for the contractor, access panels are provided for all controls and the compressor from the side of the unit.

• Compressor Short Cycling Protection – To protect the compressor against rapid short cycling.• High and Low Pressure Protection - To protect the compressor against high discharge pressure and low suction pressure, and

to guarantee safe operation of compressor.• Filter Drier - Filter drier is factory supplied ( Field installed) for all sizes.

Capacities at other ambient temperatures as shown. 2. For matched conditions,at entering condition other than shown;consult SKM. 3. Direct interpolation is permissible but extrapolation is prohibited. 4. Combination ratings are based on indoor and outdoor units at the same elevation and connected by 25 ft. (7.6 m) of refrigerant tubing.For tubing in excess of 25 feet,slight capacity reduction will occur. Do not exceed 120 feet tubing length without checking with SKM.

Notes :

1. Pipe diameters are based on equivalent length of copper tubing sizes. 2. Pipe sizes are based on 2ºF (1.1ºC) or less temperature losses for liquid and suction line in equivalent pipe length. 3. If the condensing unit is below the evaporating unit, the maximum lift should not exceed to 66 feet. 4. Do not exceed 120 feet piping length without checking with SKM. 5. These sizes are for guidance only. For detailed proper piping, refer to recognized piping references like ASHRAE Guide and Data Book. The recommended or required suction and liquid line sizes do not necessarily correspond with the refrigerant connections

available on the outdoor or indoor unit. Necessary transformation may be required and it’s field performed.

Refrigerant PipingCorrect design and size of refrigerant piping

is necessary for proper operation. The refrigerant piping generally should be designed to accomplish the following:

a. To ensure proper refrigerant feed to the evaporator.

b. To provide practical refrigerant line sizes without excessive pressure drop.

c. To maintain uniform return of lubricating oil to the compressor.

d. To prevent refrigerant from entering the compressor and causing compressor damage due to “slugging”.

Ducted mini split Air Conditioning system shall composed of a compact design indoor fan coil unit and floor or Rooftop mounted outside air cooled condensing unit, rated with AHRI standards 210/240.

CONDENSING UNIT: The condensing unit shall be composed of compressor, condenser, coil, condenser fan and motor.

CONDENSER COIL The condenser coil shall be air cooled constructed of high efficiency inner grooved copper tube mechanically expanded into hi-efficiency aluminum fins and tested against leakage by high pressure under water.

COMPRESSOR • Compressor shall be hermetic scroll type, refrigerant gas cooled, furnished with internal high temperature motor overload protection device. • Compressor have an internal pressure relief assembly to protect against excessive pressure differential.

CONDENSER FANFor top discharge air delivery, the fan shall be equipped with statically and dynamically balanced alloy blades, and inherent corrosion resistant shaft. Complete fan assembly is mounted downward on the strong and acrylic coated fan guard.

MOTORThe motor shall be totally enclosed air over (TEAO), six pole.

CONTROLSCondensing unit shall be provided with a control panel enclosure comprising all electrical control devices except for the field supplied room thermostat and shall include the following components as minimum: • Compressor and condenser fan motor contactor• Anti recycling time delay relay• Terminal for external connections.

INDOOR UNIT: The indoor unit/air handler shall be composed of evaporator coil, fan motor assembly and the metering device.

EVAPORATOR COILEvaporator coil shall be constructed of high efficiency copper tubes, mechanically bonded to aluminium fins. The coil consists of headers of seamless copper and flow control distributor.

EVAPORATOR FANFan shall be double inlet, double width, direct driven with centrifugal type wheel. Fan wheel shall be with multi forward curved blades. Fan shall be statically and dynamically balanced. Fan housing and wheel shall be made of galvanized steel sheet.

MOTORMotor shall be single phase, 3 speed permanent split capacitor type, suitable for 220-240V/1Ph/50-60Hz.Highly efficient with integral thermal protection. Motor shall have high power factor and shall be with permanent lubricated sleeve bearings.

METERING DEVICEIndoor unit shall be equipped with special type thermostatic expansion valve for R410A refrigerant.

CASINGThe unit casing shall be made of zinc coated galvanized steel sheets conforming to JIS-G3302 and ASTM-A525 that shall be phospatized and then electro statically dry powder coated of approx 60 microns to provide an extremely tough, scratch resistance, and excellent anti corrosive protection.
