PIPING INSTALLATION
Refrigerant Piping
NOTE:
For maximum serviceability, it is recommended to have refrigerant piping and
drain connections on the outside.
Piping Preparation
1. Do not open service valves or remove protective caps on pipes until all connections are made.
2. Keep tubing free of dirt, sand, moisture and contaminants.
3. Insulate each refrigerant pipe and condensate hose with minimum 3/8” (10 mm) wall
thermal pipe insulation.
4. Bind refrigerant pipes, the condensate hose and interconnecting cable together with
cable ties at 12-inch (25.4 mm) intervals.
Use refrigeration grade piping ONLY. Uses of other piping will void the Manufacturer’s Warranty.
CAUTION
Oil Return Bend
When the outdoor unit is more than 30 feet (9m) above the
indoor unit, an oil return bend must be added for every
20 feet (6m) of connection pipe.
Piping Connections to Indoor Unit
1. Feed refrigerant pipes, drain hose and interconnecting wires
assembly through wall hole from outdoor to the indoor unit.
2. Adjust the length and carefully bend refrigerant pipes to meet
indoor unit refrigerant pipe connections with proper tools to
avoid kinks.
3. Apply a small amount of refrigerant oil to the flare connection
on the refrigerant pipes.
