HK32EA001 Installation
1. Disconnect Power
2. Configure the dipswitch.
3. Connect terminals as shown in the wiring diagram.
4. Reapply power.
5. Check operation: (this will provide a shortened 2 second defrost
cycle).
a. Jump R to Y.
b. Jump across the DFT terminals.
c. Short across the speedup pins.
d. Verify the relays toggle on/off based on the timing below.
Test Mode Times
Function Actual Time Equivalent Test Time
Defrost Time 10 minutes 2.34 seconds
Interval Time 30 minutes 7.03 seconds
60 minutes 14.06 seconds
90 minutes 21.09 seconds
6. Disconnect power.
7. Remove all jumpers.
8. Reapply power.
HK32EA003/HK32EA008 Installation
1. Disconnect Power
2. Configure the dipswitch.
3. Connect terminals as shown in the wiring diagram.
4. Reapply power.
5. Check operation: (this will provide a full 10minute defrost cycle if
DFT pins remain shorted).
a. Jump R to Y.
b. Jump across the DFT terminals.
c. Short across the speedup pins for 2 seconds and release. The
T1/T2 relay turns on (removes the ASC timer).
d. Short across the speedup pins for 5 seconds and release.
e. Verify the relays toggle on/off (removes interval timer).
6. Disconnect power.
7. Remove all jumpers.
8. Reapply power.
