Operations
Winterizing the Unit
1. Shut off the water supply. Disconnect the water
inlet hose from the front of your console.
2. Connect all high pressure solution hoses and tools
that may have water in them.
3. Start the unit and turn solution pump on. Open the
tool valve until water pressure drops.
4. Turn off solution pump. Fill the water box with
approximately two gallons of 100% glycol base
anti-freeze.
5. Turn the solution pump switch ON.
6. 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.
7. Turn the solution pump switch OFF. Attach the
winterizing loop hose with attachment, Part
#86260700, 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.
8. Open temperature control 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. 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.
