SHUTDOWN AND DAILY
MAINTENANCE
1. Run fresh water through the chemical injection
system to flush out chemicals.
2. We recommend removing as much moisture
from your vacuum hoses as is reasonable. This
will prevent spillage of solution in your vehicle
when replacing hoses.
3. Position the throttle control to approximately 3/4
of the way out, but no less than 1/2 out.
4. Disconnect the vacuum hoses from the unit.
5. Push the throttle all the way in to idle and allow
the unit to run for 1 minute in order to remove
all moisture from the vacuum pump.
NOTE: If finishing for the day: Pull throttle all
the way out, plug the vacuum inlet and spray
WD-40 (or equivalent) into the vacuum
lubrication cup (located at front of console) for 5
seconds. This will lubricate the vacuum pump.
Push the throttle back to idle and continue to
step #6.
6. Turn the ignition switch to the OFF position.
7. Turn the water supply faucet off. Bleed the
pressure out of the water supply hose by
loosening the hose at the water supply. Unhook
water supply hose and store in vehicle.
8. Relieve pressure from the cleaning tools and
pressure hoses by activating the valve on the
tool. Disconnect the tools and pressure hoses
from the unit and store all items.
9. Drain the waste tank and dispose of waste in a
proper manner.
NEVER dispose of waste in storm drains, water
ways, or on ground areas. Always dispose of
waste in accordance with Local, State, or Federal
law.
10. Remove the strainer basket from the waste
tank, clean out any accumulated debris, and re-
install. Inspect the vacuum inlet filter inside the
waste tank. If there is any lint or debris, remove
and clean filter.
NOTE:
filter, grip the plastic hexagonal section of filter.
Grasping filter by the screen may collapse or
ruin the filter. Re-install the filter hand-tight.
NEVER operate this unit with this filter removed,
damaged or improperly installed.
NOTE: When replacing this filter, we recommend
using the stainless steel PROCHEM filter (Part
#14-806518) only. This will prevent rust and
corrosion from entering the vacuum system.
11. At the end of your work day, rinse out the waste
tank with fresh water. DUO Deodorizer may be
added to the waste tank to inhibit the growth of
bacteria.
12. Clean the unit, tools, hoses, van interior, etc., as
needed. Inspect ALL equipment for any
damage, wear, leaks, etc.
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.
