WHL-003 REV. 7.14.14
Do not thread a cap or plug into the relief valve under any circumstances! Explosion and property damage, serious injury, or death may
result.
F. FILLING THE HEATER
When filling the water heater, open a hot water tap to release air in the tank and piping. The tank must be full of water before the heater
is turned on. Failure to ensure the water heater is full before turning it on will result in damage to the water heater, and could result in
property damage. Such damages ARE NOT covered by water heater warranty.
Make certain that the field installed drain valve is completely closed.
Open the shut-off valve in the cold water supply line.
Open the hot water faucets to allow air to vent from the heater and piping.
Allow sufficient time for the heater to completely fill with water.
Verify elements are installed correctly. Check for leaks.
G. SCALDING
This heater can deliver scalding water. Be careful whenever using hot water to avoid
scalding injury. Certain appliances, such as dishwashers and automatic clothes washers
may require increased water temperature. By setting the thermostat on this heater to
obtain the increased water temperature required by these appliances, you may create
the potential for scald injury.
To protect against injury, you should install a mixing valve in the water system. This
valve will reduce point of discharge temperature by mixing cold and hot water in branch
supply lines. Such valves are available from your local plumbing supplier.
Table 3 details the relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the
safest water temperature for your applications.
A temperature limiting or mixing valve is recommended in installations servicing disabled or elderly persons, or children. Take extreme
caution to avoid scalding when temperature limiting or mixing valves are not used.
