OPERATIONS
HIGH PRESSURE SHUTDOWN &
RETURN TO LOW PRESSURE SYSTEM
1. Adjust High Pressure regulator to set pressure
at 400 psi.
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"
operations.
4. Squeeze pressure washer gun trigger again to
remove any residual pressure
5. Disconnect high pressure gun and hose from
high pressure disconnect.
6. 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 basic pressure wand (P/N 60-950168)
or 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 selection valve from the
"hot" position to the "warm" position.
2. Ensure that the system is operating in low-
pressure mode (HP units only). Adjust low-
pressure regulator to set pressure at 100 psi.
3. Allow solution temperature to cool below
160 deg F.
4. Begin de-flooding operation.
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.
