Starting up the PowerStar
Checking for leaks and purging air
• Verify all circuit breakers supplying power to the water heater are turned off.
• Open all hot water taps supplied by the water heater and inspect all water connections for leaks.
• With all hot water taps still open, inspect each tap to ensure all air in the lines has been purged out.
• With the air purged and taps still flowing, turn on all circuit breakers supplying the water heater.
• Close all hot water taps and proceed to the next section.
Adjusting the temperature dial
• The temperature adjustment is made using the dial on the bottom edge of the unit. The adjustment
is between approximately 95°F and 135°F. Turning the dial clockwise increases the temperature
setting as indicated by the marking on the unit.
Adjusting the flow
• Open fully both inlet and outlet shut-off valves at the heater, then :
• Turn on fully the highest flowing hot water faucet (e.g., bathtub) served by the water heater.
• Adjust the outlet shut-off valve until the water flow rate from the hot faucet corresponds to the value
given in Graph 1 below.
