NOncE: Indicates a situation that could result in equipment or property-damage only accidents.

Important Environmental Concerns! Scientific research has shown that certain man-made chemicals can affect the earth's naturally occurring stratospheric ozohe layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential-impact to the environment. Trane advocates the responsibl_e handling of all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs.

Responsible Refrigerant Practices! Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry .. AII technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

&wARNING R-410A Refrigerant under Higher Pressure than R-22! The unit described in this manual uses R-410A refrigerant which operates at higher pressures than R-22 refrigerant. Use ONLY R-410A rated service equipment or components with this unit. For specific handling concerns with R-410A, please contact your lOcal Trane representative. Failure to use R-410A rated service equipment or components could result in equipment or components exploding under R-410A high pressures which could resutt in death, serious injury, or equipment damage.

Refrigerant Piping

Evaporator Coil Orientation Important: Applies only to TWE/261150 and 7561180 when positioned for vertical upflow. Unit

is shipped in the horizontal position. If installing in the vertical position, the coil must be reoriented by rotating the coi/4 degrees (control box side) from the shipped position. See instructions and Figure 4 below.

Process for reorienting evaporator coil on TWE126, 150, 156 and 180 only. 1. Remove screws from top evaporator coil bracket (bracket that attaches coil to cabinet and runs

the length of the unit).

2. Rotate evaporator coil approximately 4 degrees clockwise- looking from the control box end (see Figure 4). When the evaporator coil is rotated, the lower set of evaporator coil bracket holes will align with the support bracket (from which it was originally fastened).

3. Reinsert screws in evaporator coil bracket.

Preparation

NOTICE Unit Damage!

Rotate 4° clockwise

Do not apply heat to remove seal caps until the gauge port cores have been removed. If seal caps are intact, application of heat may generate excessive pressure in the unit and result in damage to the coil or expansion valve.

The air handler is designed so that refrigerant piping can enter from either the right or left hand side. It is shipped with the intent that the refrigerant lines will enter from the left hand side. To convert to right hand entry, unbraze the elbow on the suction line and rotate 180° and rebraze.

Important: Access to refrigerant lines is limited in all horizontal and some vertical applications. Therefore, refrigerant lines should be stubbed out and temporarily capped prior to setting the air handler. Protect adjacent surfaces from heat damage when brazing in and around the air handler.

Installation

Horizontal Suspension

30

If the air handler will be suspended, use a suspension mounting kit to isolate the unit from the structure. This is usually accomplished through the use of spring or rubber isolators, which are offered as an accesSory. Mounting rods must be field supplied. Isolator selection is dependent upon total unit weight including accessories. Approximate unit weights are provided in Table 1 and Table 2, p. 7.

NOTICE Equipment Damage! Before hanging the unit on suspension rods, reinforce the cabinet around the suspension holes by using a large washer inside the cabinet. Washers should be between the skin of the air handler and the nut on the suspension rod.

Align holes in the cabinet with structural supports and secure suspension rods to the structure, then to the air handler cabinet. If hole locations do not permit proper alignment with existing structure, it may be necessary to field fabricate cross members on existing structural beams.

Note: When other than bottom return is to be used, side panel removed for return duct installation must be secured over the bottom opening.

Leveling This air handler has a double sloped drain pan. In order to assure proper drainage along the length of the drain pan, it is important to have the unit properly leveled. Be sure the air handler is level.

Auxiliary Drain Pan A field fabricated, auxiliary drain pan should be installed under the unit for all horizontal applications and when air handlers are installed above ceilings or in other locations where condensate overflow may cause damage. This drain pan will eliminate any excess condensation that may be due to extreme humidity or an obstructed drain in the primary drain pan. Drain lines from this pan must be installed, but should not be connected to the primary drain line from the unit. Isolate the auxiliary drain pan from both the air handler and the structure.

&WARNING Fiberglass Wool! Product contains fiberglass wool. Disturbing the insulation in this product during installation, maintenance or repair will expose you to airborne particles of glass wool fibers and ceramic fibers known to the state of California to cause cancer through inhalation. Glass wool fibers may also cause respiratory, skin or eye irritation.

Precautionary Measures • Avoid breathing fiberglass dust.

• Use a NIOSH approved dust/mist respirator.

• Avoid contact with the skin or eyes. Wear long-sleeved, loose-fitting clothing, gloves, and eye protection.

• Wash clothes separately from other clothing: rinse washer thoroughly.

• Operations such as sawing~ blowing, tear-out, and spraying may generate fiber concentrations requiring additional respiratory protection. Use the appropriate NIOSH approved respirator in these situations.

First Aid Measures

Eye Contact- Flush eyes with water to remove dust. If symptoms persist. seek medical attention.

Skin Contact - Wash affected areas gently with soap and warm water after handling.

Refrigerant Piping

SSA-SVX06A-EN

Installation, brazing, leak testing and evacuation of refrigerant Jines are covered in the installation instructions packaged with the outdoor unit. Read the instructions before beginning installation of refrigerant lines.

Locate cloth bag(s) attached to the refrigerant tube of the coil that contains a stainless steel clamp and insulation material (approximately 9" long by 4" wide) for each refrigerant circuit. This is for attaching and insulating the expansion valve bulb (s) to the suction line(s).

On air handlers that will have refrigerant lines entering the cabinet from the left side, remove the split rubber grommet from the knockout in the end of the air handler. Uncoil the cap tube with the bulb attached at the expansion valve and place the grommet on the cap tube. With the grommet around the tube, push the bulb through the hole and position the grommet back into its original position (one bulb and cap tube on single circuit units and two bulbs and cap tubes on dual circuit units).

Attach the bulb(s) on a horizontal section oftube where the entire length ofthe bulb is in contact with the tube, (see Figure 14, p. 31) approximately 45 degrees off vertical (a 10 or 2 o'clock position), 10 to 12 inches outside of the air handler.

On air handlers that will have refrigerant lines entering the cabinet from the right side, the bulb(s) should be attached to the suction tube(s) inside the cabinet in the sam·e manner as above. approximately 10" from the right end of the unit.

After attaching to the suction line{s), either inside or outside of the cabinet, wrap the insulation around the bulb(s) and suction tube(s). Refrigerant piping should be insulated.

NOTICE Equipment Damage!

Figure 14. Remote Bulb Installation

Between /10 and 2 O'Clock"-...,.

Bulb Retaining Clip

Ensure that the refrigerant lines passing through the cabinet are not resting on sharp sheet metal edges and that the bulb(s) are attached to the suction line of the same circuit.

Installation

Condensate Piping

Filters

The drain pan condensate connection is a female slip joint type for 1" Schedule 40 PVC pipe. Use PVC cement and tubing as required (field supplied) to construct a trap. A union or flexible tubing and clamps may be installed if the drain pan is to be removed periodically for cleaning.

Important: When air handler is instafled in the vertical position and close proximity trapping of condensate is required, use of a subbase accessory to raise the air handler for clearance of the drain trap is recommended. See Figure 15 for a typical drain trap assembly.

Air handlers are shipped with throwaway filters Figure 16. Filter Replacement installed. For replacement filters consult the air handler service facts for correct size and number.

To replace filters from the end of the unit, remove lower access panel (either end) and slide old filters out and replace with new ones. To replace from the front of the unit, remove one "L' shaped angle. Remove and replace filters and reinstaii"L' shaped angle. See Figure 16.

To convert from 1" filter to a 2" filter on units so equipped, remove lower access panels from both ends of the air handler. Remove screws and rotate the "L' shaped angles from both the top and bottom ofthefiltertrack 180°to increase the width of the filter opening.

Frame

Duct Connections

The supply and return ducts should be connected to the unit with flame retardant duct connectors to reduce vibration transmission. The return duct should be sized to the same dimensions as the return inlet of the unit.

Important: Duct flanges are provided for attachment of the duct work and are packaged on the outside of the cabinet for TWE150, 180 and 240 and TWE126, 156 and 201. The duct flanges are fastened to the top coil support bracket in the TWE051, 061, 076, 090, 101 and 120 models.

Air Flow Settings

Maintenance Perform all of the indicated maintenance procedures at the intervals scheduled. This will prolong the life of the unit and reduce the possibility of costly equipment failure.

Fan Belt Adjustment

38

.&WARNING Rotating Components! Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

The fan belts must be inspected periodically to assure proper unit operation.

Replacement is necessary if the belts appear frayed or worn.

When removing or installing the new belts, do not stretch them over the sheaves. Loosen the belts using the belt tension adjustment bolts on the motor mounting base.

Once the new belts are installed, using a Browning or Gates tension gauge (or equivalent) illustrated in Figure 20; adjust the belt tension as follows;

1. To determine the appropriate belt deflection;

a. Measure the center-to-center shaft distance (in inches) between the fan and motor sheaves.

b. Divide the distance measured in Step 1a by 64; the resulting value represents the amount of belt deflection that corresponds to the proper belt tension.

2. Set the large 0-ring on the belt tension gauge at the deflection value determined in Step 1 b.

3. Set the small 0-ring at zero on the force scale of the gauge plunger.

4. Place the large end of the gauge at the center of the belt span; then depress the gauge plunger until the large 0-ring is even with the top of the next belt or even with a straightedge placed across the fan and motor sheaves.

5. Remove the belt tension gauge. The small 0-ring now indicates a number other than zero on the plunger's force scale. This number represents the force {in pounds) required to give the needed deflection.

6. Compare the "force" scale reading (Step 51 with the appropriate "force" value listed in Table 12, p. 39. lfthe "force" reading is outside the range, readjust the belt tension.

Note: Actual belt deflection "force" must not exceed the maximum "force" value shown in Figure 20.

Recheck the belt tension at least twice during the first 2 to 3 days of operation. Belt tension may decrease until the new belts are "run in':

Product contains fiberglass wool. Disturbing the insulation in this product during installation, maintenance or repair will expose you to airborne particles of glass wool fibers and ceramic fibers known to the state of California to cause cancer through inhalation. Glass wool fibers may also cause respiratory, skin or eye irritation.

&.WARNING Hazardous Voltage w/Capacitors! Disconnect all electric power, including remote disconnects and discharge all motor start/run capacitors before servicing. Follow proper lockout/tagout procedures to ensure the power cannot be inadvertently energized. For variable frequency drives or other energy storing components provided by Trane or others, refer to the appropriate manufacturer's Hterature for allowable waiting periods for discharge of capacitors. Verify with an appropriate voltmeter that all capacitors have discharged. Failure to disconnect power and discharge capacitors before servicing could result in death or serious injury.

NOTICE Operating Under Vacuum Do not operate or apply power to the compressor while under a vacuum. Failure to follow these instructions will result in compressor failure.

1. Inspect air filters and clean (or replace) if necessary.

2. Check unit wiring to ensure all connections are tight and that the wiring insulation is intact.

3. Check drain pans and condensate piping to insure they are free of obstacles.

4. Manually rotate the indoor fan to ensure proper operation.

5. Inspect the evaporator coils for dirt and debris. If the coils appear dirty, clean them.

6. Observe indoor fan operation and correct any unusual or excessive vibration. Clean blower wheels as needed.

Maintenance

Annually (Cooling Season}

Coil Cleaning

40

The following maintenance procedures must be performed at the beginning of each cooling seiason to ensure efficient unit operation.

1. Perform all of the monthly maintenance inspections.

2. With the unit operating, check unit superheat and record the reading in the "Maintenance Log:'

3. Remove any accumulation of dust and/or dirt from the unit casing.

4. Remove corrosion from any surface and repaint. Check the gasket around the control panel door to ensure it fits correctly and is in good condition to prevent water leakage.

5. Inspect the evaporator fan belt. If it is worn or frayed, replace it.

6. Inspect the control panel wiring to ensure that all connections are tight and that the insulation is intact.

7. Check refrigerant piping and fittings for leaks.

8. Inspect the evaporator coils for dirt and debris. If the coils appear dirty, clean them.

Regular coil maintenance, including annual cleaning-enhances the unit's operating efficiency by minimizing:

- compressor head pressure and amperage draw;

- water carryover;

- fan brake horsepower and

- static pressure losses.

At least once each year-or more often if the unit is located in a "dirty" environment-clean the coil using the instructions outlined below. Be sure to follow these instructions as closely as possible to avoid damaging the coils. To clean refrigerant coils, use a soft brush and a sprayer. Contact your local Parts Center for appropriate detergents.

1. Remove enough panels from the unit to gain safe access to coil.

.&WARNING No Step Surface! Do not walk on the sheet metal base. Walking on the base could cause the supporting metal to collapse. Failure of the base could result in death or serious injury.

2. Straighten any bent coil fins with a fin comb.

3. Remove loose dirt and debris from both sides of the coil with a soft brush.

4. Mix the detergent with water according to the manufacturer's instructions. If desired, heat the solution to 150° F maximum to improve its cleansing capability.

5. Pour the cleaning solution into the sprayer.

6. Spray the leaving-airflow side of the coil first; then spray the opposite side ofthe coil. Allow the cleaning solution to stand on the coil for five minutes.

7. Rinse both sides of the coil with coot clean water.

8. Inspect both sides of the coil; if it still appears to be dirty, repeat Steps 7 and 8.

9. Reinstall all of the components and panels removed in Step 1; then restore power to the unit.

10. Using a fin comb, straighten any coil fins that were inadvertently bent during the cleaning process.

Important Environmental Concerns!

Scientific research has shown that certain man-made chemicals can affect the earth's naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, F.luorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants-including industry replacements for CFCs such as HCFCs and HFCs.

Responsible Refrigerant Practices!

Trane believes that responsible refrigerant practices are important to the environment. our customers, and the air conditioning industry. All. technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipmentthatis used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them .

.&.wARNING Contains R-410A Refrigerant! System contains oil and refrigerant under high pressure. Recover refrigerant to relieve pressure before opening the system. See unit nameplate for refrigerant type. Do not use .non-approved refrigerants, refrigerant substitutes, or refrigerant additives. Use ONLY R-410A rated service equipment or components with this unit. For specific handling concerns with R-410A, please contact your local Trane representative. Failure to use R-410A rated service equipment or components and/or failure to follow proper procedures or the use of non-approved refrigerants, refrigerant substitutes, or refrigerant additives could result in death or serious injury or equipment damage.
