(7) Prospector 100 PSI Carpet Extractor
6.0 Storage and Freeze Protection
You must winterize your Prospector Carpet Extractor to protect the pump system from freezing and also damage
being caused to fittings and valves. Damage due to freezing is not covered under the warranty. Store your extractor in
temperatures over 40 degrees Fahrenheit. If you plan on storing your extractor in freezing conditions or for a long period
of time, the following procedure should help prevent your Prospector Carpet Extractor from freezing and prevent pump
and seals from drying out.
Recommended Procedure for Storage
• In a separate container, mix 1/2-gallon of water with 1/2-gallon of automotive radiator antifreeze (ethylene glycol
type). Mix well and pour into the solution tank.
• Connect the pressure hose to the female quick disconnect (QD) on the front of the machine. Insert an open-ended male
QD into the female QD on the end of the pressure hose.
• When primed, turn down the pressure to 100 PSI.
• Disconnect the open-ended QD and connect the solution hose to the male QD at the auto-fill/chemical feed connection.
CAUTION: applying high pressure (over 100 PSI) to the chemical feed system will damage the mechanism.
• With the chemical feed supply tube at the bottom of the solution tank, turn on the pump and allow to circulate for 10
minutes. Check to make sure the chemical supply tube is drawing the antifreeze solution. This will introduce antifreeze
into the chemical feed system.
• Disconnect the solution hose from the chemical feed and allow the system to bypass for 10 minutes. This will work
antifreeze into the pressure gauge.
• Attach and wands and hand tools that will also be stored with the Prospector Carpet Extractor. Open the valve for 30
seconds, directing the spray to the solution tank. Disconnect the hose and with the 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.
• Turn off the pump and disconnect all hoses and tools. Vacuum out the solution tank and thoroughly drain the recovery
tank and vacuum hose.
To return to service, flush the pressure system by repeating the above steps, using fresh water in place of
antifreeze.
