STORAGE AND FREEZE PROTECTION
Care must be taken to protect your MASTERFORCE® from freezing. Freezing could seriously damage the MasterForce
a
s well as fittings and valves. Freezing is not covered under the limited warranty and you should always store your equip-
ment in areas where the temperature remains above 40° F. If you plan on storing the MasterForce for a prolonged period
of time, the following procedure should help prevent your MasterForce from freezing, and prevent the pump seals from dry-
ing out.
Recommended Procedure for Storage:
STEP ONE:
In a separate container, mix 1 gallon of water with 1 gallon of automotive radiator antifreeze
(ethylene glycol type). Mix well, and pour into the solution tank, keeping approximately 1
pint for use in Step Five.
STEP TWO:
Connect the pressure hose to the female quick disconnect (QD) on the front of the machine.
Turn the shut off valve on the pressure hose to the off position. Insert an open-ended male
QD into the female QD on the end of the pressure hose.
STEP THREE:
Prime the solution pump, directing the flow of solution back into the solution tank. When
primed, turn down the pressure to 100psi if equipped.
Note: If your machine does not have the auto chemical feed option, skip to step 6.
STEP FOUR:
Disconnect the open-ended QD and connect the solution hose to the male QD at the auto
fill/chemical feed connection if equipped.
CAUTION: Applying high pressure (over 100 psi) to the chemical feed system will damage
the mechanism.
STEP FIVE:
Place the chemical feed supply tube into the container. With the pint of antifreeze from Step
One, turn on the pump, and allow to circulate for 10 minutes. Check to make sure the chemi-
cal supply tube is drawing the antifreeze solution. This will introduce antifreeze into the
chemical feed system. Disconnect the solution hose from the chemical feed.
STEP SIX:
Allow the system to bypass for 10 minutes. This will work antifreeze into the pressure gauge.
STEP SEVEN:
Attach any wands and hand tools that will also be stored with your MasterForce. Open valve
for 30 seconds, directing the spray to the solution tank. Disconnect hose and with valve open
and the jets pointing down, depress the dimple on the male QD. This will drain the solution
out of the tool. Drain thoroughly before storing.
STEP EIGHT:
Vacuum out the solution tank and thoroughly drain the waste tank and vacuum hose. Turn
off the pump and disconnect all hoses and tools.
The automatic pump-out option does not require freeze protection, as long as the waste
tank is completely drained, and allowed to thoroughly dry.
Return to Service:
To return the MasterForce to service, flush the pressure system by repeating the above steps,
using fresh water in place of the antifreeze solution.
