Releasing Air Charge
CAUTION
The coil is shipped from the factory pressurized with dry
air. Pierce a hole in the rubber plug that seals the vapor
line to relieve the pressure before removing the plugs.
NOTE
- If there is no pressure released when the vapor
line rubber plug is pierced, check the coil for leaks before
continuing with the installation.
The coil is shipped with a 10 + 3 psig dry air holding charge.
Puncture the suction line rubber plug to release the
charge. Remove the rubber plug. Ensure that the coil is
void of pressure.

1.
Left-Hand and Right-Hand Discharge
—
The coil
must have a 1/2" slope from the rear of the cabinet
to the drain.
Position the coil adjacent to the furnace
cabinet and align the six screw clearance holes in the
coil casing with the furnace engagement holes. Use
six field-provided #8 X 1" screws to secure the coil
casing to the furnace (see figures 3 and 4).
2.
Right-Hand Air Discharge with Field-Provided
Spacer
—
The coil must have a 1/2" slope from the
rear of the cabinet to the drain.
Position the coil in
the left-to-right configuration on the service access
side of the furnace. Insert a field-provided spacer
between the furnace and the coil. Use field-provided
screws to secure the coil casing, spacer and the
furnace together. The spacer should be long enough
to allow room for proper installation (approximately 6
inches minimum). See figure 5.
