(1/4 TURN FASTENERS)
Interlock
These units have an interlock circuit incorporated into the control circuit, brought
out to two terminals. These terminals are shorted out for factory testing.
On site the shorting loop is to be removed and two wires taken to a pair of
volt free contacts in the water pump starter/contactor/relay or flow switch so
that the heat pump cannot operate unless the water pump is operating. (See
figures 5 & 6).
