FREEZE PROTECTION
!
If the unit is exposed to freezing weather
conditions, the water inside of the unit may
freeze, resulting in SERIOUS DAMAGE to
the unit. The following is recommended to
prevent this from occurring during the cold
weather season:
1. Always park the unit in a heated building
when not in use.
2. While out in operation, avoid long periods of
shut down as the unit generates heat while
running. Keep the unit running just prior to
leaving for the next job.
3. If a heated building is not available, winterize
the unit with anti-freeze.
It is not possible to winterize units that have
auxiliary water tanks. If the unit has an auxiliary
water tank(s), it must be stored in a heated
building.
WINTERIZING YOUR UNIT WITH ANTI-
FREEZE:
1. Shut off the water supply to the unit and
disconnect the water inlet hose from the
console.
2. Connect all solution hoses and a tool to the
console.
3. Start the unit with the water pump in the
ON
position. Open a valve on the tool and drain the
thermal well until liquid stops flowing.
4. Fill the water box with one gallon
of 100%
glycol based anti-freeze.
5. Start the unit and set the throttle control cable
to the idle position. Insure the water pump is on.
Open a tool valve until anti-freeze comes out of
the tool. Repeat this procedure with
ALL
remaining tools and hoses.
6. After the tools and solution hoses have been
filled with anti-freeze, disconnect and store
them.
Recover all anti-freeze that comes out of the
tools and hoses and store in an approved
container. ALWAYS re-use or re-cycle anti-
freeze.
7. Prime the chemical injection system with a
100% glycol based antifreeze. Insert the
chemical inlet and prime tube into the anti-
freeze container. Turn the chemical valve to
PRIME
until anti-freeze comes out of the prime
hose. Turn the chemical valve to the
ON
(chemical) position. Ensure that the flow meter
indicates flow while the attached tools solution
valves are opened. Ensure that all anti-freeze
that comes out of the chemical hose goes into an
approved container.
After
25 seconds
, turn the chemical valve to the
OFF
position.
8. Allow the unit to run until anti-freeze comes
out of the jets. The unit is now winterized.
REMOVING ANTI-FREEZE FROM THE
UNIT:
1. Connect the solution hoses to the unit, with a
tool attached to the opposite end. Start the unit.
Turn the water pump on. Open the tool valve
and ensure that the anti-freeze goes into an
approved container. Allow the anti-freeze to
flow into the container until all anti-freeze has
been drained.
2. Remove the cap from the water box.
3. Fill the water box with fresh water and repeat
step 1.
4. Connect the water inlet hose to the unit and
turn the water supply on. Connect all tools and
solution hoses that were winterized to the
solution outlet connection.
