Operations
Winterizing Your Unit
1. Shut off the water supply. Disconnect the water
inlet hose from the front of your console.
2. Start the unit and turn solution pump on. Open the
tool valve until water pressure drops.
3. Turn off the solution pump. Fill the water box with
approximately two gallons of 100% glycol base
anti-freeze.
4. Turn the solution pump ON.
5. Connect all solution pressure hoses and tools that
may have water in them.
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. 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.
9. Turn the chemical valve and flow simulator valves
to the open position. Make 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.
10. After completing these procedures, shut the unit
down. The unit is now winterized.
