Replacing the Low-Temperature Cutoff Thermostat:
1. Ensure that the Aqua-Hot has been completely shut down
and that all the power sources have been disconnected.
2. Locate the Low-Temperature Cutoff Thermostat on the
Aqua-Hot. See Figure 44.
3. Disconnect the defective LTCO thermostat by separating
the quick-disconnect terminals.
4. Using a ⅝” wrench or crow’s foot wrench, remove the
defective LTCO thermostat from the Aqua-Hot.
5. Install the replacement LTCO torquing it to
15 in-lbs ONLY
.
Anything more than 15 in-lbs of torque will damage the
thermostat and possibly the unit.
6. Connect wire J4-1 and wire J4-2 to the replacement Low-
Temperature Cutoff Thermostat.
7. Test for normal operation.
Failure to disconnect all power supplies and/or allow
the unit to cool before servicing could cause serious
damage or personal injury.
