UPHOLSTERY CLEANING
Upholstery tool, part #86285260, PRV NO. 78513
1. Set temperature as desired and slow down the
engine speed to minimize excess heat.
2. Use one (1) “86229980, PRV NO. 80015” spray
tip in tool.
SHUTDOWN AND DAILY MAINTENANCE
1. Close chemical metering valve.
2. Allow the unit to run for 2 minutes with the
vacuum hose disconnected to remove moisture.
Spray WD40 (or equivalent) into the vacuum
lubrication cup. This will prevent corrosion due
to moisture.
3. Set engine throttle at idle position and allow the
water temperature to cool down, unitizing the
bypass valve in the open position to bleed off
residual hot water left in the system.
4. Turn off ignition switch.
5. Disconnect all hoses and tools.
6. Drain waste tank and rinse with clean water.
DE-FLOODING OPERATIONS
De-flooding operations involve removal of water from
carpet and flooring. This differs from normal
cleaning operations in that no water or solution is
required. An automatic waste pump-out is highly
recommended for all de-flooding operations due to
the large amount of water removal often required.
1. Start
unit.
2. Set pressure regulator at 100 psi.
3. Shut off water pump.
4. Begin de-flooding operations.
5. Under almost all conditions, the unit will
sufficiently cool itself. If you find yourself
operating in extreme heat: Hook up a water
supply; turn on the water pump at 100 psi, and
crack the bypass valve slightly to provide
additional cooling.
FREEZING
PROTECTION
If the unit is exposed to freezing weather the
water in the unit may freeze, causing SERIOUS
DAMAGE to the unit. To avoid this, the following
is recommended during the cold weather
season.
When the unit is not in use, always park it in a
heated building.
While in operation, avoid long shutdowns as the unit
provides heat while running. Shut it down just prior
to leaving for the next job.
If a heated building is not available, we recommend
that you winterize the unit with anti-freeze. At
present, it is only possible to winterize units, which
do not have an auxiliary water tank. Units with
auxiliary water tanks must be stored in a heated
building when not in use.
OVERHEATING PROTECTION
Air cooled engines rely on the flow of air over the
engine for cooling operations. Ensure that there is
sufficient air flow in the van. Never operate the unit
with all the vehicle doors closed and no alternate
ventilation system.
