Releasing Air Charge
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.
CAUTION
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.
Installation
Risk of explosion or re.
Can cause injury or death.
Recover all refrigerant to relieve pressure before
opening the system.
WARNING
Install the furnace or air handler according to the installation
instructions provided with the unit.
NOTE: In areas of high humidity, use foam tape to insulate
the suction line section in the cabinet as shown in Figure 1.

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 eld-provided #8 X 1” screws to secure the coil
casing to the furnace (see Figure 3 and Figure 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 conguration on the service access side
of the furnace. Insert a eld-provided spacer between
the furnace and the coil. Use eld-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.
NOTE: When the coil is connected directly with a
condensing furnace, the coil must be level from
return end to supply end. The front (access side) of
the furnace may be pitched downward up to 1 inch to
accommodate a ½-inch pitched coil.
3. Secure the supply duct to the coil cabinet.
4. Refer to the instructions provided with the condensing
unit for leak testing, evacuating and charging
procedures. Always check the entire system for leaks
before charging.
5. Applications using BH1P-60 D-width unit with
C-width furnace — Figure 2 shows an application
that includes a D-width coil and a C-width furnace.
This application requires construction of an insulated,
eld-supplied block-o plate to cover the open space
on the coil housing.
