CAUTION: To prevent improper performance and/or unit component failures, do not leave system open to atmosphere any longer than minimum required for instal- lation. POE oil in compressor is extremely susceptible to moisture absorption. Always keep ends of tubing sealed during installation.
CAUTION: To prevent improper performance or equip- ment failure this caution must be followed. If ANY refrigerant tubing is buried, provide a 6 in. vertical rise at service valve. Refrigerant tubing lengths up to 36 in. may be buried without further special consideration. Do not bury lines over 36 in. in length.
CAUTION: To prevent damage to unit or service valves observe the following:
• Use a brazing shield.
•Wrap service valves with wet cloth or use a heat sink material.
Outdoor units may be connected to indoor section using accessory tubing package or
There are no
If refrigerant tubes or indoor coil are exposed to atmosphere, they must be evacuated to 500 microns to eliminate contamination and moisture in the system.
A. OUTDOOR UNIT CONNECTED TO FACTORY- APPROVED INDOOR UNIT
Factory refrigerant charge is for a 15 ft line set. Outdoor unit contains correct system refrigerant charge for operation with ARI rated indoor unit. Check refrigerant charge for maximum effi- ciency. The charge must be adjusted based on the actual line set length. Add or subtract 0.6 oz/ft for line sets longer or shorter than 15 ft.
B. INSTALL LIQUID-LINE FILTER DRIER
CAUTION: To avoid performance loss and compressor failure, installation of filter drier in liquid line is required.
Refer to Fig. 6 and install filter drier as follows:
1.Braze
2.Braze filter drier between connector tube and liquid tube to indoor coil. Flow arrow must point towards indoor coil.
