coming power terminal block,
connect the black wire to line
L1, the red wire to line L2, and
the white wire to line L3.

STEP 4: Do not turn power on to equipment until the heating module is
filled with water, as severe damage may occur to heater elements.
Prior to shipping, a rust inhibitor powder was added to the hot water
tank. This powder will mix with the added water to prevent rust build-
up inside the tank.
Install water fill spout (item 15, page 20, shipped loose). Spout open-
ing should be facing up. Insert water hose and fill. Do not over fill to
allow for thermal expansion. (Maximum is 80 gallons). After heater
tank has been filled to the top, operate for one week and then add
one quart of oil to slow evaporation. Be sure to replace spout plug,
hand tight only.
Turn on main power supply to unit. Set 7 day programmable timer
to desired ON/OFF time and switch machine power on, Water will
heat up to operating temperature in 30 to 60 minutes. The heater will
turn off automatically when 200°F is reached. Water will come out of
heater fill spout due to heat expansion. However, this will stop after
temperature is reached.
Leave main power on to the machine to ensure hot water on pump
start up.
