Assembly Instructions
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 (item 15, page 20, 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 automatically when
200°F is reached. Water will come out of heater fill spout due to heat expan-
sion. However, this will stop after temperature is reached.
Leave main power on to the machine to ensure hot water on pump start up.
STEP 3: Remove the hex head
screws from electricazl 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 item 16 on Exploded View -
Left Side).
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 electrician
attach the proper supply cord to the
terminal labeled L1, L2 and L3.
ATTENTION: Demander à un électricien
qualifié de raccorder le cordon
d'alimentation approprié à la borne
étiquetée L1, L2 et L3.
Use copper conductors only.
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.
