Water Connections NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE MAIN WATER SUPPLY VALVE. After shutting the main water supply valve, open a faucet to relieve the water line pressure to prevent any water from leaking out of the pipes while making the water connections to the water heater.
Page 9
Water Connections continued- Your water supplier or local plumbing inspector should be contacted on how to control this situation. After installation of the water lines, open the main water supply valve and fill the water heater. While the water heater is filling, open several hot water faucets to allow air to escape from the water system.

Water Connections continued- WARNING Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system.
Electrical Connections Before any electrical connections are made, be sure that the water heater is full of water and that the manual shut-off valve in the cold-water supply line is open. Check the rating plate and wiring diagram before proceeding. This electric water heater was built and wired in accordance with the IEC testing approvals requirements.

GENERAL OPERATION 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.
Thermostat Adjustment Setting the Water Temperature 1. The thermostat has been set at the factory at about 52 °C to reduce the risk of scald injury. We recommend this setting as this ensures the most safe and economic operation of the water heater. This way the water temperature is maintained at about 52 °C.
Page 16
Thermostat Adjustment continued- LIGHT INDICATOR The operation of the heating element is indicated by the light indicator that stays on until the temperature in the tank has reached the set level or until the heater has been deliberately switched off. ANTIFREEZING PROTECTION When the water heater is not in use for longer periods of time, it should be protected from freezing by setting the temperature to minimum possible...
MAINTENANCE IMPORTANT The water heater should be inspected at a minimum of annually by a qualified service technician for damaged components. DO NOT operate this water heater if any part is found damaged. Shut off the electric power whenever the water supply to the water heater is off.
Page 18
Maintenance continued- 3. At least once a year, check the combination temperature and pressure relief valve to ensure that the valve has not become encrusted with lime. Lift the lever at the top of the temperature-pressure relief valve several times until the valve seats properly without leaking and operates freely. WARNING When lifting lever of temperature-pressure relief valve, hot water will be released under pressure.
Page 19
Maintenance continued- Draining the Water Heater 1. Unplug the water heater. 2. Open the hot tap to let hot water go out. Continue flowing until cold water is running out from faucet. 3. Turn off cold water supply. 4. Close the hot water faucet. 5.
