WARNING:
Heaters may not function properly if
elements are not installed per these
instructions.
IMPORTANT: Application of H5HK-035Q
and H5HK-035S Electric Heat Kits.
The three (3)- 160 Deg. F High Temperature
limits installed on the element assembly
must be replaced with the three (3)- 210 Deg.
F High Temperature limits supplied with the
electric heat kit on all 7.5 Ton package Air
Conditioners and 7.5 & 10 Ton Q5,Q6 & P6
Package units. Ensure all wiring and con-
nections are to unit wiring diagram when
complete. Short cycling of equipment will
occur if proper limits are not installed. (See
table 1 for proper limit application).
Remove Element/Field Wiring Access panel.
*P4S(M,N) Series – Determine the number of
element close-off plates to be removed from
mounting panel based on size of kit being in-
stalled. Set screws aside for later use and discard
close-off plates.
P6SP/Q6SP/Q5SN Series – Remove the ele-
ment opening cover. Four (4) mounting plates
are required around the element kit to secure
and seal the opening. Mount the longer plates
to the top and bottom of the element assembly
prior to inserting into the unit. Secure the element
assembly in place using screws removed with
the cover. Attach the remaining two side close
off plates. NOTE: 240V -009Q and -018Q kits
require the addition of a blank element plate
included in the kit. See Figure 1B.
WARNING:
Install heater elements starting
closest to the blower with high
temperature limits located at the
top of the assembly. See Figure 1A.
Be careful not to damage heater
element wires or ceramic element
supports while inserting through
panel opening. Ensure heater
element support rods slide into the
alignment holes in the back of the
element housing box. Secure the
element assembly to the mounting
panel with the screws removed
when removing the element close-
off plates.
