START - UP
1. After all plumbing lines have been properly installed and secured, open all hot water taps and turn on the
water pressure system.
2. Allow water to run a few minutes until all air is expeled and all outlets flow clear of air. Failure to expel air may cause
an air pocket in the tank. This will cause the heating element to burn out, as it will not be in contact with water. All the
air may not be expelled after purge, however over a period of time (two weeks) the remaining air in the tank will be
absorbed by the water.
3. Check for leaks.
4. Replace electrical access cover and turn on power.

TROUBLESHOOTING
WARNING: If temperature and safety valve is leaking it must be replaced.

within 30 minutes check to be sure there is power at the
thermostat. This can be done by checking voltage at the
top of the thermostat, between the two top wires (on left
and right side of thermostat). If system voltage is pres-
ent, check for power at the heating element. If power is
available at heating element, heating element is burned
out. If power is not available at heating element, replace
thermostat.
