Installation

These instructions do not attempt to cover all variations in systems, nor to provide for every possible contingency to be met in connection with installation. Should further information be desired or should particular problems arise which are not sufficiently covered for the purchaser’s purpose, the matter should be referred to the manufacturer.

General

This manual covers installation of the

TWE200 and 240E dual circuit air handlers. These air handler models incorporate a single slab coil assembly, improved application flexibility, servicing, maintenance accessibility and an improved accessory line. They are fully convertible, (vertical to horizontal discharge) without field removal or reorientation of the coil assembly.

They are shipped ready for horizontal installation.

All units have one drain pan that can be installed in any one of four positions. This allows for vertical or horizontal applications and right or left exit.

Note:

The TWE200E and TWE240E dual circuit units have a mixed face coil.

condensate drainage connections.

After this is determined, the following preparations should be made.

Repositioning Drain Pan

These air handlers come with one drain pan that can be installed in any one of four positions; this allows for vertical or horizontal application and right or left condensate line connection. The drain pan can also be easily removed for periodic cleaning.

Note:

All air handlers are shipped with the drain pan installed in the horizontal position and the connection on the left side (as shown in Figure 2). If an alternate position is required, the drain pan should be repositioned before setting the air handler.

Figure 2.

Inspection

Inspect material carefully for any shipping damage. If damaged, it must be reported to, and claims made against the transportation company.

Replace damaged parts with authorized parts only. Check the unit nameplate to confirm that the proper unit was shipped. Available power supply must be compatible with electrical characteristics on component nameplate.

Installation Preparations

The final position for the air handler must be dictated by required service access to it, weight distribution over structural supports, and by the locations of electrical, refrigerant and

Process for Drain Pan Relocation

1.

Remove the access plate at the opposite end of the drain connection. This plate secures and lifts the back end of the drain pan for sloping. It must be removed before the drain pan can be removed. This is done as follows: (A) remove the screw, (B) lift the access plate up, (C) pull the plate out. If the drain pan is to be moved to the vertical position also remove the other two access plates.

2.

(a) Remove the screw securing the drain pan. (b) Lift the pan up.

(c) Slide the pan out.

3.

Install the drain pan into the new position. (a) Slide the drain pan into the opening. (b) Lift the drain pan up. (c) Push it in all the way.

(d) Drop it down over the lip of the opening. Secure with screw.

4.

Install the access plate on the opposite end of the drain pain. (a)

Slide the edge of the access plate under the drain pan. (b) Lift the access plate and drain pan up. (c)

Push the access plate in. (d) Drop the access plate down over the lip of the opening. Secure with screw. If the drain pan is being moved to the vertical position, install the other access plates over the horizontal position opening.

Installation

Refrigerant Piping Preparation

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 degrees and rebraze.

Note:

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.

Caution

These air handlers are shipped with a dry nitrogen holding charge in the coil. Cut the process tube or puncture the cap to bleed off the nitrogen prior to any brazing. Temporarily cap off tubes if the refrigerant line connections are to be made later.

Caution

Properly insulate all refrigerant gas piping to prevent possible water damage due to condensation and to prevent capacity loss and possible compressor damage.

It is recommended that the dimensional drawings be studied, properly noted and checked against the selected installation site. By noting in advance which knockouts are to be used, proper clearance allowances can be made for installation and possible future service.

Note:

When installing these units

“free standing” with discharge grills and isolators, a top support with isolator should be added to prevent tipping.

Support and isolator can be attached to a wall or other appropriate structure.

Note:

If adding external accessories to the unit, additional clearances must be considered for the overall space needed.

For installation of accessories available for this air handler, follow the instructions packed with each accessory.

Installations, Limitations and

Recommendations

The general location of the air handler is normally selected by the architect, contractor and/or buyer. For proper installation the following items must be considered.

1.

Available power supply must agree with electrical data on component nameplate.

2.

If external accessories are installed on the unit, additional clearances must be provided.

3.

All duct work should be properly insulated to prevent condensation and heat loss.

4.

Refrigerant gas piping must be insulated.

Before preparing the unit for lifting, the center of gravity should be determined for lifting safety. Because of the placement of external components, the unit weight may be unevenly distributed. Approximate total unit weight and corner weights are given in Table 2.

The crated unit can be moved using a forklift of suitable capacity. For lifting the unit into an elevated mounting position, run lifting straps or slings under the unit and attach securely to the lifting device. Use spreader bars to protect the unit casing from damage. Test lift the unit to determine proper balance and stability.

Caution

Use spreader bars to prevent straps from damaging the unit. Install the bars between lifting straps, both underneath the unit and above the unit. This will prevent the straps from crushing the unit cabinet or damaging the unit finish.

Installation

Horizontal Suspension

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 2.

Caution

Before hanging the unit on suspension rods, reinforce the cabinet around the knockouts 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 (knockouts) in the cabinet with structural supports and secure suspension rods to the structure, then to the air handler cabinet. If knockout 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, the 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 or slightly sloped in the direction of the condensate connection.

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 could result in 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, loosefitting 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

Installation, brazing, leak testing and evacuation of refrigerant lines are covered in this 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 two (2) brass clamps (straps) and cork impregnated insulation material approximately 9” long by 4” wide. 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 it’s 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) approximately 45 degrees off vertical, 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 same 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 cork impregnated insulation around the bulb(s) and suction tube(s). Refrigerant piping should be insulated.

Note:

Ensure that the refrigerant lines passing through the cabinet are not resting on sharp sheet metal edges.

Installation

Condensate Piping

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.

Note:

When air handler is installed 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 4 for a typical drain trap assembly.

Filters

Air handlers are shipped with throwaway filters 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 reinstall “L” shaped angle. See Figure

5.

Figure 4.

Trap

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.

Note:

Duct flanges are provided for attachment of the duct work.

On TWE240, the duct flanges are packaged on the outside of the cabinet.

Figure 5.

Filter Replacement

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 reposition the “L” shaped angles from both the top and bottom of the filter track to increase the width of the filter opening.

Air Flow Settings

Unit is shipped for nominal airflow with nominal static pressure. Please refer to fan performance table in either the product catalog or unit service facts and select the proper drive package for each application.

Failure to do so could result in improper airflow causing coil frosting or condensate management problems. Condensate management problems such as water drip off or water blow off could be the result of too great of air face velocity across the coil.
