Operations
Upholstery Cleaning
Upholstery tool, (See Options section)
1. To protect fabrics, reduce solution temperature as
needed by opening the solution temperature
control valve on the lower front panel. Engine
speed may also be reduced slightly to reduce heat
and vacuum.
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
water displacing lubricant into the vacuum lubrica-
tion cup and cover the vacuum inlet to draw the
water displacing lubricant into the blower. This will
prevent corrosion due to moisture.
3. Set engine throttle at idle position and allow the
water temperature to cool down, utilizing the tem-
perature control valve in the open position to bleed
off residual hot water left in the system.
4. Close temperature control valve and turn off igni-
tion 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. 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 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.
