Filling the Tank
NOTE: When filling, avoid water spillage. Do not allow the
insulation of the heater to get wet as water can cause elec-
trical malfunction.
1. Close the drain valve, and then open a hot water faucet.
2. Open the cold water supply valve.
3. When water runs out of the hot faucet, the tank is full.
4. Check the system for leaks.
Draining the Tank (completely)
If the power is to be turned off during the cold season and
the tank is exposed to freezing temperatures, the water
heater must be drained. Water will expand when it freezes
and can damage the heater.
Completely drain as follows:
1. Make sure the electrical supply to the water heater is
"OFF".
2. Turn off cold water supply.
3. Connect a garden hose to the end of the drain valve
and direct this to a point lower than the heater.
4. Open a hot water faucet.
5. Open the drain valve on the heater - drain, keeping the
drain valve open during the shutdown period.
6. To refill the heater, see “Filling the Tank” section.
Installation Check List
Check Here
1. Are the fuse and wire sizes correct?
2. Is the certified relief valve installed?
3. Are you sure that in case of water leakage, the
building, furniture, carpeting or other property
will not be damaged?
4. Has the relief valve been piped to a suitable
drain point?
5. Is the relief valve discharge unobstructed?
6. Is the heater completely filled with water?
7. Is the cold supply valve open?
If the answers to the above are “Yes”, turn on the
power and enjoy all the hot water you need, all
the time.
WARNING
Do not supply power to this water heater
until you have verified that the unit is com-
pletely filled with water.
To ensure that the water heater is full of
water and that all the air has been purged
from the system, run all the hot water
faucets in the house continuously for three
(3) minutes.
