STEP 2. ATTACHING A WATER FEED TANK (CUSTOMER SUPPLIED)
It Is recommended that the water supplied to the pressure washer is by an external water tank.
To connect an external water feed tank, follow the steps below:
CAUTION: Inadequate plumbing between a feed tank and the pressure washer can cause damage to the pump from water cavitation. To
avoid water cavitation:
• Use 1" hose and fittings or larger
(provided). Supply Line Hose should
be no longer than 6'.
• Place feed tank so bottom of tank is
level to the pump inlet.
• Place the feed tank as close as
possible to the pressure washer so
the supply line hose will be as short
as possible.
• Make sure the supply line hose does
not kink.
• Never allow tank to run dry. Figure 1
Step 1. Supply a 200-gallon or larger water feed tank. (The supply line hose and necessary fittings have been provided with this pressure
washer.)
Step 2. Drill 2.25" diameter hole in the bottom of the tank for the supply line – this is the supply port. Drill a second 1.5" diameter hole a
minimum of 1 foot away from the first hole for the return line – this is the return port. Both holes need to be drilled on flat surfaces of
the tank.
Step 3. Insert supplied bulkhead fitting into each hole.
Step 4. Thread the supplied 1" elbow fitting into the supply line bulkhead fitting. Thread the supplied ¾" hose barb fitting into the return line
bulkhead fitting.
Step 5. Make sure the bottom of the water tank is level with the pump inlet on the skid frame.
Step 6. Connect the supply line (1" supply line hose provided, Figure 1):
a. Connect to the 1" elbow fitting in the supply port on the water tank. Use the t-bolt hose clamp that has been provided.
b. Connect the other end to the water inlet on the inlet filter (see Component Identification section of this manual). Use the t-bolt hose
clamp that has been provided. Make sure the connection hose does not kink.
Step 7. Connect the return line (connected to the unloader on the skid, Figure 1):
a. Connect to the 3/4" elbow onto the return line bulkhead fitting on the water tank.
b. Connect the return line to the 3/4” elbow and use the t-bolt hose clamp that has been provided.
CAUTION: To protect the pump, do not add cleaning chemicals directly to the tank water. Use the quick coupler chemical injector
provided. Then follow all instructions and precautions for chemical spraying.
See Operating the Pressure Washer, Step 2. Set Up for Chemical Spray section in this manual.
