with force. Water may contain chemicals or
contaminants that can be a health hazard upon contact.
Airflow shut-off
The HVE3000 will automatically shut off airflow to the
blower when the recovery tank is full. This prevents
water and debris from entering the motor. When the
recovery tank becomes excessively dirty, or if there is
too much foam in the tank, the float may not function
properly. When the blower emits a high-pitched whine
and there is no vacuum generated, it most likely means
that the ball float has engaged and that the tank is full
and needs to be emptied, or that excessive foam is
present. When this occurs, check the tank and empty it
if necessary, and use a defoamer any time foam is
present.
MAINTENANCE
WARNING! ELECTRIC SHOCK HAZARD.
Unplug the
unit before performing any maintenance.
Before each use
Inspect the electrical cord for damage.
Look for
fraying, cuts, etc. Do not use the unit if you find any
damage. Call +1 360-757-7776 to locate the nearest
service center.
Check the filter basket and HEPA filter
(Fig. D).
Performance is greatly reduced when either filter is
clogged.
Check the sump pump float valve
(Fig. D).
Remove
any clogs or obstructions to the float mechanism.
Check the manual drain hose
for clogs or kinks.
Check all hose fittings.
Look for cracks, debris, and
damaged threads or seals.
Check ball float valve.
Ensure cover screen is clean.
After each use
Clean filter basket and top cover.
Release cover
clamps, remove the cover, and lift out basket. Rinse
basket, basket basin, and cover with water to clean.
(Clean also as needed during use.)
Clean recovery tank, float valve, and airflow shutoff
valve.
1. Release four cover assembly latches and lift off cover
assembly (see Fig. D). With gravity drain hose directed
into a suitable drain, remove any accumulated debris
and wash recovery tank interior with an all-purpose
detergent. Rinse interior with fresh water. Allow the unit
to drain completely through the gravity drain hose.
2. Slide airflow shutoff ball valve assembly downward off
of the vacuum standpipe (Fig. D
; see also “Remove float
ball assembly,” p. 6). Rinse valve assembly clean. Make
sure the float ball moves freely inside the cage and is
free of any debris. Replace ball valve assembly.
3. Wipe off pump, float, float arm assembly and tank
interior with a damp cloth. Allow tank interior and cover
assembly to dry completely before replacing the cover
assembly.
To maintain appearance
, wipe interior and exterior
surfaces with a damp cloth. For deep cleaning and to
add a protective shine to the exterior, use Dri-Eaz
MicroGuard Cleaner and MicroGuard Protectant or a
similar automotive interior treatment.
Monthly
Use an all-purpose silicone spray
to lubricate wheels,
castors and latches. Take care to wipe up any excess
spray, as it may create slippery surfaces.
As needed
Replace HEPA filter.
Replace when the filter is visibly
dirty. To access the filter, remove the filter cover plate
thumbscrews and lift off the plate. Replacement filters
are sold in packs of four. Ask for Dri-Eaz part no. F503
or Sapphire part no. 20-045.
