WINTERIZING YOUR UNIT
1. Shut off the water supply. Disconnect the water
inlet hose from the front of your console.
2. Connect all high pressure hoses and tools
that may have water in them.
3. Start the unit. Open the tool valve until water
pressure drops and water stops flowing.
4. Turn off the engine.
5. Fill the water box with approximately two gallons
of 100% glycol base anti-freeze.
6. Start the unit.
7. Open the tool valve until anti-freeze begins to
come out of the tool. Recover ALL anti-freeze
that comes out of the tools into an approved
container. We strongly recommend that you re-
cycle and re-use the anti-freeze.
Repeat this procedure with all the remaining
tools. After all tools and pressure hoses have
been filled with anti-freeze, disconnect and store
them.
8. Turn unit off and attach the winterizing loop hose
with attachment, Part # 86260700, PRV NO.
10-805380, to the solution outlet connection and
the water inlet connection. Turn the solution
pump switch ON.
Allow the unit to run for approximately 3 minutes
with the winterizing loop hose attached.
Open bypass valve and allow anti-freeze to flow
to waste tank.
9. Prime the chemical system with 50/50 anti-
freeze/water mix. Insert the chemical inlet and
prime discharge tubes into the anti-freeze
container. Turn the chemical valve to PRIME
until anti-freeze begins to flow out of the prime
hose.
10. Now turn the chemical valve to the open
position, making certain that the flow meter
indicates flow and that all anti-freeze drains out
of the chemical hose into an approved container,
after 30 seconds, turn off both valves.
When disposing of used anti-freeze, observe
local laws and regulations. Do not drain onto
the ground or into storm drainage systems.
