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.
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 5—Make 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.
NOTE:
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 line 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.
7. Do not suspend refrigerant tubing from joists and studs with a
rigid wire or strap which comes in direct contact with the
tubing. (See Fig. 3.)
