3.6The built-in temperature high limit is factory set at 180°F (82°C). This control works best when it is set about 40°F (22°C) above the water outlet temperature. To adjust the limit control setting remove the small panel on the limit control to access the adjustment screw. Under normal operation the heater should not cycle on the limit control.

3.7If the limit trips it must be manually reset before the heater will operate. Prior to reset, the condition(s) which caused the trip shall be corrected.

4.0MAINTENANCE

4.1Service to the unit shall only be done when the power is disconnected at the mains.

4.2After the first few days of operation, and periodically thereafter, inspect for piping leaks and loose electrical connections.

4.3The EPWD unit, because it is used in an open loop water heating system, may be subject to sludge build-up if the water is hard and untreated. This unit must be drained at regular intervals (depending on water conditions and operating time) to remove sludge. Once a year a flange heater must be removed and the vessel inspected and cleaned as required. Local conditions may cause this inspection time to vary.
