Starting up

4.6.1 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.

These figures are based on an inlet water temperature of 55 °F
and a supply voltage of 240 volts. If the inlet water temperature
is lower than 55 °F, or if the supply voltage is less than 240
volts, then the outlet temperature will be lower than what is
shown in Fig. 8. If a higher outlet water temperature is desired,
then reduce the flow rate and/or supply the unit with 240 volts.
Before leaving the site, the installer should
demonstrate the unit to the user and give
them this guide.

4.6.2 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 131 °F. Turning the dial clockwise
increases the temperature setting as indicated by the
marking on the unit.
4.6.3 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 Fig. 8
below.
