Winterizing Your Unit - Prochem EVEREST LP Operating Instructions Manual

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 and turn water pump on. Open the
tool valve until water pressure drops and water
stops flowing.
4. Fill the water box with approximately two gallons
of 100% glycol base anti-freeze.
5. Turn the solution pump override switch to the
override position and start the unit. 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 #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.
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. Now turn the chemical valve and flow simulator
valves 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.
HIGH PRESSURE
Turn solution pressure valve to high pressure
and key the high pressure wand until anti-freeze
begins to come out of the wand. Recover all
anti-freeze into an approved container. We
strongly recommend that you recycle and re-use
the anti-freeze.
After completing these procedures, shut the unit
down. The unit is now winterized.
