ELEMENT POWER WIRING
Elements are shipped with element power wiring 
ready for attachment to top terminals of the three 
(3) pole control contactors. Connect the two (2) 
– BLACK w/WH, two (2) – RED w/BK, and two 
(2) – Yellow w/BK wires to the corresponding T1, 
T2, and T3 terminals of the contactor.
NOTE: H5HK-030 & 035Q models only - 240 
Volt, 30 and 35 Kw kits supplied with two sets 
of six (6) element power wires - the second set 
of wires will connect to the second or top right 
control contactor. Connect the two (2) BLACK w/
WH, two (2) – RED w/BK, and two (2) – Yellow 
w/BK wires to the corresponding T1, T2, and T3 
terminals of this second contactor
.
Complete the power wiring connections for all 
kits by attaching the supplied Black, Red, and 
Yellow or (Black with Yellow markings) from the 
bottom of the three (3) pole contactors on –009Q, 
-018S, and –035S models or from the bottom 
of the Circuit Breakers on –018Q and –035Q 
models. Connect Black, Red, and Yellow to Lines 
L1, L2, and L3 respectively.
Refer to the specific detailed wiring diagram for 
all final connections. Make sure all connections 
are secure.
NOTICE TO INSTALLER - Mark the appropriate 
box on the unit rating label with a permanent 
“X” to indicate which heater kit has been 
installed.
Low Voltage Control Wiring
Connect the heater kit six (6) pin plug connector 
to the units mating plug receptacle located in 
the upper right hand side of the heater element 
control compartment. Make sure the connec-
tion is secure.
Complete the low voltage connections by joining 
the three (3) pin plug and receptacle connectors 
shipped as part of the heater kit assembly. Make 
sure the connection is secure.
Wiring Diagrams - Wiring Diagrams are shipped 
with each H5HK Heater kit assembly. Attach 
the wiring diagram in plain view on the heater 
element mounting panel. Make sure surface is 
clean and oil free before applying.
AIRFLOW
The maximum external static pressure (ESP) for 
the unit is listed on the unit rating label.
IMPORTANT: High Static Applications of the 
H5HK 30 kW & 35 kW kits. 
When installing the 30 kW & 35 kW H5HK 
Heater kits in the Q5/Q6 series packaged heat 
pumps and in conjunction with a high static 
drive kit; or on duct systems where the unit 
ESP is greater then 0.75 in-W.C. for the 7.5T 
units or 0.9 in-W.C. for 10T units; then the 
heater kit will require an additional accessory 
kit. See Table 1 for accessory description 
and part number.
The blower speed is preset at the factory for 
optimum operation in Heating and Cooling 
modes. It may be necessary for some applica-
tions to change the factory set speed. To change 
the blower speed see the “Blower Speed” sec-
tion in the Installation Instructions shipped with 
the unit.
If a lower blower speed is desired, then the 
heater element high temperature limits must 
be checked for proper operation. Nuisance 
tripping and cycling of the limits may result with 
too little of airflow. Limit operation should be 
checked with return air temperatures between 
72 F and 78 F. 
If a higher blower speed is desired from the factory 
then no other modifications are required.
