OPERATION & SYSTEMS

HIGH PRESSURE SHUTDOWN &
RETURN TO LOW PRESSURE SYSTEM
1. Turn off water pump and release pressure.
2. Bleed off excessive pressure build-up by
operating pressure washer gun for 5 seconds.
3. Move solution selector control valve from “High
Pressure” operations to “Low Pressure”
operation.
4. Squeeze pressure washer gun trigger again to
remove any residual pressure
5. Disconnect high pressure gun and hose from
high pressure disconnect.
6. Open ball valve, located between the chemical
pump and water pump.
7. Operate under normal low pressure instruction
or follow normal shutdown procedures.
Pro-Chem recommends the use of the Pro-
Chem chemical injector (P/N 61-951538) for
use in combination with any chemical/detergent
additives.
Pro-Chem also recommends the use of Pro-
Chem high-pressure spray wands. Pro-Chem
offers a dual barrel wand (P/N 60-950505).
Contact your Pro-Chem dealer for
recommendations in your particular application.
The operation of the high-pressure system also
requires a high-pressure hose capable of
handling the increased pressure loads of the
high-pressure system. NEVER use your low-
pressure system hoses with the high-pressure
system. Pro-Chem offers a special high
pressure hose, P/N 10-805513, rated for
pressure washer activities. Only use Pro-Chem
approved hoses and fittings. Ensure that your
hoses and fittings are rated for your operational
pressures.
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. Move the temperature control lever from the
“hot” position to the “warm” position.
2. Ensure that the solution pump is in off position.
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.
