7.0 REFRIGERANT CONNECTIONS
Keep the coil connections sealed until refrigerant connections are made. See the installation
instructions for the outdoor unit for details on line sizing, tubing installation, and charging
information. The coil is shipped at no charge. Evacuate the system before charging with
refrigerant. Install the refrigerant tubing so that it does not block the service access to the front of
the unit.
Nitrogen should ow through the refrigerant lines while brazing.
Use a brazing shield to protect the cabinet’s paint and a wet rag to protect the rubber grommet
from being damaged by torch ames. After the refrigerant connections are made, seal the gap
around the connections with pressure sensitive gaskets.
7.1 CONDENSATE DRAIN TUBING
Consult local codes for specic requirements.
1. When making drain tting connections to the drain pan, use a thin layer of teon paste,
silicone or teon tape to seal.
2. When making drain tting connections to the drain pan, do not overtighten. Overtightening
ttings can split the pipe connetions on the drain pan.
