Assembly Instructions
STEP 1:
Place machine in a conve-
nient location providing ample
support, drainage and room for
maintenance. Remove pallet bolts
and remove pallet, then re-install
bolts to level machine by adjusting
(machine must be level).
STEP 2:
Place the pump package
on top of the heat exchange and
attach the small high pressure hose
to the fittings as shown.
STEP 3:
Remove the hex head
screws from electrical access
panel.
NOTE: bottom right screw will
only loosen; access panel is
designed to pivot on this screw.
Once access panel is rotated out
of the way, attach the electrical
harness from the pressure
washer to the heating module as
follows:
a.
Feed pressure washer wire
harness through the upper
wire hole located on the
side of the machine
b.
On the right side of the
incoming power terminal
block, connect the black
wire to line L1, the red wire
to line L2, and the white
wire to line L3.
c.
Attach the green wire to the
ground terminal block.
CAUTION: Have qualified electri-
cian attach the proper supply
cord to the terminal labeled L1,

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 was added to the hot water tank. This will
mix with the added water to prevent rust build-up inside the tank.
Install water fill spout (see Component ID page, shipped loose). Spout
opening 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 automat-
ically 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.
