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 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
(See Cabinet).
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.

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. Rust
inhibitor should be added when adding water after several hours of
operation to replace evaporated water.
Install water fill spout (See Cabinet). 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 auto-
matically 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.
