Thermoswitch (8732A Only) (Optional)
The 8732A, only, can be equipped with an optional interlock
thermoswitch, P/N 2450-095-x. To install or replace this:
1. Stand the unit with the water connectors up to prevent spills.
2. Remove the water outlet connector.
3. Replace the connector with the thermoswitch. Sparingly apply
pipe sealing compound to the external threads, only, of the
thermoswitch. Do not contaminate the coolant with pipe sealant.
4. Check for coolant leaks upon completion.
Connect the thermoswitch to the interlock as follows (see Figure 3):
1. Unscrew the large knurled ring-nut [A] at the lower end of the
coupling jack assembly. Pull it off the thermoswitch jack [B].
Unscrew the small knurled cover fitting from the base plug [D] of
the connector to release the base.
2. Thread the control switch wires through the clamp [E] with the
washers [F] inside and its threaded fitting in place. Use short tips
on the wires and put spaghetti sleeves over the ends if necessary.
3. Solder the switch leads to the lugs [G] of the connector base.
NOTE: The ring-nut [A] must be in place over the base plug [G]
with the knurled end facing out.
4. Screw on the cover ring, then fasten the cable clamp [E] in place
and tighten both yoke screws [H].
5. Put the plug back on the thermoswitch and tighten the nut [A].
CAUTION
If installed, connect optional interlock before applying RF power.
