Fig. 2ÐUnit Reference Drawing

Install TXV kit to indoor coil as follows:

1.Install suction tube adapter.

2.Install liquid flare-to-sweat adapter.

3.Install TXV on liquid flare-to-sweat adapter.

4.Connect external equalizer tube to fitting on suction tube adapter.

5.Position sensing bulb on horizontal portion of suction tube adapter. Secure using supplied hardware. Insulate bulb after installation. (See Fig. 6.)

NOTE: To enhance heating HSPF, flow arrow must point toward outdoor coil.

Step 6ÐMake Piping Connections

Outdoor units may be connected to indoor sections using accessory tubing package or field-supplied refrigerant grade tubing of correct size and condition. For tubing requirements beyond 50 ft, consult Long-Line Application Guideline which is available at your local distributor.

6. Leak check all connections.

DO NOT BURY MORE THAN 36 IN. OF REFRIGERANT TUBING IN GROUND. If any section of tubing is buried, there must be a 6-in. vertical rise to the valve connections on the outdoor unit. If more than the recommended length is buried, refrigerant may migrate to cooler buried section during extended periods of unit shutdown, causing refrigerant slugging and possible compressor damage at start-up.

Step 5ÐInstall Liquid Solenoid Valve (LSV)Ð Optional

Heating efficiency (HSPF) can be improved with the addition of a LSV. Refer to presale literature for rating with this enhancement. Install per Installation Instructions included in accessory kit part number KHALS0101LLS.

In some cases noise in the living area has been traced to gas pulsations from improper installation of equipment.

INSTALLATION RECOMMENDATIONS

1.Locate the unit away from windows.

2.Ensure that vapor and liquid tube diameters are appropriate to the capacity of the unit. (See Table 1.)

3.Run refrigerant tubes as directly as possible by avoiding unnecessary turns and bends.

4.Leave some slack between the structure and the unit to absorb vibration.

5.When passing refrigerant tubes through the wall, seal the opening with RTV or other pliable silicon-based caulk. (See Fig. 3.)

6.Avoid direct lineset contact with water pipes, ductwork, floor joists, wall studs, floors, and walls.
