Instructions for use

Starting and Before connecting the power, fillthe tank and system with water and check for leaks. To be

testing certain that all the air is out of the water system, open the hot water faucets on your fixtures until constant water flows from them, otherwise damage to the element may occur.

To start the heating cycle:

A)first make sure tank is full. Otherwise the heating element may be damaged.

B)move red on/off switch (letter F, Fig 3-4) to the ON position (to the left).

C)turn the thermostat dial clockwise to the preferred position. The red light will come on and remain on until that temperature has been reached, at which point

the light will go off, but will automatically come back on when the water temperature drops below the setting chosen.

protection

Warning: The "very hot" is a scalding temperature.

 

The lowest setting is that point on the dial where (with cold water in the tank) the

 

light comes on when dialing from the lowest counter clockwise position. This lowest

 

setting is for an approximate temperature of 27° C / 80° F.

 

WARNING:

Adjusting the temperature dial above the "hot" setting will increase

 

 

the risk of scald injury. Households with small children, the elderly,

 

 

or invalids may require a temperature setting below "hot".

Turning the heater's thermostat to the lowest setting provides economical and effective freeze protection.
