GENERAL OPERATION
When the switch is closed, the operation of this electric water heater is
automatic. The thermostats are preset to the “HOT” setting to provide a
water temperature of approximately 120°F (49°C) to reduce the risk of scald
injury.
Care must be taken whenever using hot water to avoid scalding injury.
Certain appliances require high temperature hot water (such as dishwashers
and automatic clothes washers).
TO FILL THE WATER HEATER
1. Close the water heater drain valve (if provided) by inserting a standard
flat head screwdriver into the slot and turning clockwise.
2. Open the cold water supply shut-off valve.
3. Open several hot water faucets to allow air to escape from the system.
4. When a steady stream of water flows from the faucets, the water heater
is filled. Close the faucets and check for water leaks at the water heater
drain valve, combination temperature and pressure relief valve and the
hot and cold water connections.
TO DRAIN THE WATER HEATER
Should it become necessary to completely drain the water heater, make sure
you follow the steps below:
1. Disconnect the power supply to the water heater. Consult the plumbing
professional or electric company in your area for service.
2. Close the cold water supply shut-off valve.
3. Open the drain valve (if provided) on the water heater by inserting a
standard flat head screwdriver into the slot and turning counter-
clockwise. The drain valve has threads on the end that will allow
connection of a standard hose coupling. For those models not equipped
with a drain valve, disconnect cold water inlet piping at a convenient
connection location as close to an adequate drain as possible.
CAUTION! THIS WATER MAY BE HOT.
4. Open a hot water faucet to allow air to enter the system.
To refill the water heater, refer to “TO FILL THE WATER HEATER.”
Before closing the switch to allow electric current to flow to the
water heater, make certain that the water heater is full of water and
that the cold water inlet valve is open. Complete failure of the
heating element(s) will result if they are not totally immersed in
water at all times. Failure of the element(s) due to dry-firing is not
covered by warranty.
CAUTION
Scalding may occur within five (5) seconds at a temperature setting of
140°F (60°C).
