5.0 REFRIGERANT CONNECTIONS

Keep coil connections sealed until refrigerant connections are to be made. See outdoor
unit manual for details on line sizing, tubing installation, evacuation and charging infor-
mation.
• To install the refrigerant connections, first install the refrigerant block-off plate (locat-
ed in the Parts Bag, see Figure 10) around the refrigerant connections. Braze all fit-
tings. When refrigerant lines have cooled, insert the foam gasket (located in the parts
bag, see Figure 10) around the refrigerant lines, between the coil and the refrigerant
block-off plate.
IMPORTANT: The refrigerant block-off plate MUST be installed around the refrig-
erant connections before brazing.
• When making braze connections close to outside of cabinet, use a brazing shield to
protect cabinet paint from being damaged from torch flame.
• If the installation is in a tight location, it might be convenient to make some external
tubing connections before setting unit in place.
IMPORTANT: Install refrigerant tubing so it does not block service access to front of unit.
24 in. clearance is required for filter, coil or blower removal and service access.

5.1 FLOWCHECK PISTONS

See outdoor unit installation instructions for correct flowcheck piston sizes and proper
piston installation instructions.
• Indoor coil piston size is indicated by the digits underscored in the indoor coil model
number.
IMPORTANT: It is important that the proper piston sizes be used dependent on
indoor coil, outdoor unit combination and application.
