Operations
High Pressure Shutdown & Return To Low
Pressure System
1. Turn off solution 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.

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 solution temperature control lever from
the "hot" position to the "warm" position.
2. Ensure that the solution pump switch is in the off
position.
3. Operate with all side and rear cargo doors open.
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 recom-
mended 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.
