BULB LOCATION

3.2 REFRIGERANT CONNECTIONS

Keep the coil connections sealed until refrigerant connections are to be made. See the Installation Instructions for the outdoor unit for details on line sizing, tubing installation, and charging information.

Coil is shipped with a low (5 - 10 PSIG) pressure charge of dry nitrogen. Evacuate the system before charging with refrigerant.

Install refrigerant tubing so that it does not block service access to the front of the unit. Nitrogen should flow through the refrigerant lines while brazing. Use a brazing shield to protect the cabinet’s paint from being damaged by torch flames. After the refrigerant connections are made, seal the gap around the connections with

pressure sensitive gasket. If necessary, cut the gasket into two pieces for a better seal (See Figure 4.)

3.3 TXV SENSING BULB

IMPORTANT: DO NOT perform any solderiing with the TEV bulb attached to any line. After soldering operations have been completed, clamp the TEV bulb securely on the

suction line at the 10 to 2 o’clock position with the strap provided in the parts bag. Insulate the TEV sensing bulb and suction line with the provided pressure sensitive

insulation (size 4” x 7”) and secure with provided wire ties. IMPORTANT: TEV sensing bulb should be located on a horizontal section of suction line,

just outside of coil box. Sensing bulb should never be placed on any aluminum tube.

3.4 FLOW CHECK PISTON

NOTICE

FOR PROPER SYSTEM OPERATION, IT MAY BE NECESSARY TO REPLACE THE PISTON INSTALLED IN THE INDOOR COIL. CHECK THE SERVICE VALVES ON THIS UNIT TO SEE IF A NOTICE TAG ALONG WITH A PLASTIC BAG CONTAINING A PISTON IS ATTACHED. IF ONE IS PRESENT A CHANGE OF THE PISTON IS REQUIRED. FAILURE TO CHANGE THE PISTON CAN RESULT IN IMPROPER PERFORMANCE OF THE SYSTEM.

The flow check piston is a multi-purpose device. With flow into the compression nut end from the liquid line, the piston is in a check position and acts as the expansion device with flow through the metering orifice in the center of the piston. The “O” ring on the end of the piston prevents refrigerant from bypassing the metering orifice. Flow from the metering orifice is centered into a distributor which serves to evenly distribute refrigerant to the evaporator circuits. With flow in the reverse direction (direction of arrows on the distributor body), the piston is forced off the seat and liquid from the condenser is allowed to free flow around the piston.

It is essential that the heat pump indoor and outdoor sections be properly matched. Use only matched components as shown in sales specification sheets.

A piston size that is too small will cause starving and one that is too large will cause flooding. In either case, system performance, reliability and charge balance (heating and cooling) will be unacceptable.

Page 9

Change the piston in the distributor on the indoor coil before installing the coil and charging the system following the procedure below:

• Using a back-up wrench on the distributor body, loosen the compression nut to gain access to the piston.

• Using the wire provided with replacement pistons, run (hooked end) through hole in piston.

• Hook nose end of piston and lift gently from distributor body.

• Replace piston with one of proper size (see Table 4), install piston with gasket end of piston in distributor. Do not force piston into distributor.

• NOTE: With piston in distributor, seal end should be down and should not be seen looking in end of distributor. Piston must be free to rotate and move up and down. Make sure piston is free to move in distributor body.

• Insure distributor gasket is located properly in the distributor body.

• Replace compression nut using back-up wrench on distributor body. Torque compression nut end with 8 to 10 ft. lbs.

• Original piston size is stamped on outside of distributor body. Remove new piston size label from poly bag new piston came in and install new size label on outside of distributor tube.

• Check fittings for leaks after installation, evacuation and charging is complete.

IMPORTANT: Do not attempt to drill pistons to size in the field. Metering holes have a special chamfered inlet and cannot be modified.

IMPORTANT: Do not replace the neoprene “O” ring on the piston with any type of seal. Contact the parts department for the exactly replacement of “O” ring.

FIGURE 6

PISTON AND DISTRIBUTOR ASSEMBLY

3.5 CONDENSATE DRAIN TUBING

Condensate trap (on gas furnace applications) for the primary drain is optional except when required by local code or ordinance.

IMPORTANT: When making drain fitting connections to the drain pan, use a thin layer of Teflon paste, silicone or Teflon tape and install hand tight.

IMPORTANT: When making drain fitting connections to drain pan, do not overtighten. Overtightening fittings can split pipe connetions on the drain pan.

• Install drain lines so they do not block service access to front of the unit. Minimum

clearance of 24 inches is required for filter, coil or blower removal and service access.

• Make sure unit is level or pitched slightly toward primary drain connection so that

water will drain completely from the pan. (See Figure 7.)

• Do not reduce drain line size less than connection size provided on condensate drain pan.

• All drain lines must be pitched downward away from the unit a minimum of 1/8” per foot of

line to ensure proper drainage.

Page 10

• Do not connect condensate drain line to a closed or open sewer pipe. Run condensate to an open drain or outdoors.

• The drain line should be insulated where necessary to prevent sweating and damage due to condensate forming on the outside surface of the line.

• Make provisions for disconnecting and cleaning of the primary drain line should it become necessary. Install a 3 in. trap in the primary drain line as close to the unit as possible. Make sure that the top of the trap is below connection to the drain pan to allow complete drainage of pan (See Figure 7).

FIGURE 7

CONDENSATE DRAIN TRAP

DO NOT OPERATE UNIT WITHOUT

CONDENSATE DRAIN TRAP.

UNIT

DO NOT OVERTIGHTEN DRAIN FITTING

UNIT MUST BE SLIGHTLY INCLINED

TOWARD DRAIN CONNECTION.

• Auxiliary drain line should be run to a place where it will be noticeable if it becomes operational. Occupant should be warned that a problem exists if water should begin running from the auxiliary drain line.

• Plug the unused drain connection with the plugs provided in the parts bag, using a thin layer of teflon paste, silicone or teflon tape to form a water tight seal.

• Test condensate drain pan and drain line after installation is complete. Pour water into drain pan, enough to fill drain trap and line. Check to make sure drain pan is draining completely, no leaks are found in drain line fittings, and water is draining from the termination of the primary drain line.

CAUTION

4.0 MAINTENANCE

WARNING

For continuing high performance and to minimize possible equipment failure, it is essential that annual maintenance be performed on this equipment. Consult your local dealer as to the availability of a maintenance contract.

4.1 AIR FILTER

Check the system filter every ninety days or as often as found to be necessary and if obstructed, clean or replace at once.

IMPORTANT: Do not operate the system without a filter in place.

Page 11

4.2 INDOOR COIL - DRAIN PAN - DRAIN LINE

Inspect the indoor coil once each year for cleanliness and clean as necessary. In some cases, it may be necessary to remove the filter and check the return side of the coil with a mirror and flashlight.

IMPORTANT: Do not use caustic household drain cleaners or bleach in the condensate pan or near the indoor coil. Drain cleaners will quickly damage the indoor coil.
