To Assemble (4510W Only): Insert casters into sockets on bottom of canister. Push casters until seated. Attach
hose to coupling on front of can.
To Connect Hose: Insert the hose end into the tank inlet until it clicks. To remove the hose, press the button on
top of the hose inlet, and remove hose.
To Operate:
(1) For Dry Pickup (4520W): Install paper bag on inlet inside of tank. Insert the cloth lter assembly in the top
of the tank. Install motor head. The cloth lter located inside the can provides highly ecient separation
of dust and dirt particles from the incoming air stream.
(2) For Wet Pickup: Remove paper bag and cloth lter from tank. Make sure foam lter sleeve is installed on
oat assembly. Make sure oat moves freely. When the liquid level in the tank rises to a point just below
the inlet, the oat assembly shuts o air ow, thus preventing overow and possible damage to the
vacuum motor.
To Maintain: This vacuum cleaner contains no user serviceable parts. If repair is needed, please take the vacuum
cleaner to an authorized Sterling factory service center.
CAUTION Never operate vacuum for dry pick-up unless the cloth lter is properly installed and in good condition.
CAUTION A disposable paper bag cannot be used during liquid pick up.
CAUTION Do not use this vacuum to pick up hazardous materials without HEPA lter being installed.
CAUTION Never lubricate the vacuum cleaner motor. The motor bearings are permanently sealed. This vacuum is
intended for indoor or outdoor use and for wet pickup, however, it is not intended to be exposed to rain.

The vacuum cleaner is warranteed for 1 year from the date of purchase. Parts not covered under warranty are power
cords, lters, motor brushes and squeegee blades. The warranty covers only failure due to defective parts or workman-
ship and will be invalidated by improper application and abuse.
Under no circumstances should you return a failed unit to the factory. If you experience any problems with your vacuum

Limited Warranty
Model 4520P
Before Each Use:
(1) This vacuum cleaner is designed for wet only pickup. Please avoid picking up dry materials.
(2) Make sure the tank is clean, and that there is no debris in the tank that can impede the action of the pump
oat mechanism.
(3) Make sure the mesh lter bag is installed on the inlet inside the canister. The bag should be empty, and
the slide-on clamp should be installed on the bottom of the bag. Position the thin, at plastic strip that is
attached to the mesh lter bag, over the rim of the canister. This strip helps retain the bag when it lls with
debris.
(4) Make sure that the oat mounted on the underside of the motor head is able to move freely, and that the
lter on the outside of the oat housing is clean and properly in place. This lter will protect the vacuum
motor from debris.
(5) Attach the motor head to the canister using the two metal clamps mounted on the side of canister. The
pump cord exits the rear of the canister, near the top. Plug this cord into the electrical outlet on the top rear
of the motor head.
(6) Attach the long discharge hose to the brass tting on the rear of the canister. The tting is a ball coupling
type. Pull the collar of the female brass tting toward the canister before inserting the hose tting.
To Operate:
(1) The vacuum cleaner motor is controlled by the switch on the top left side of the motor head. The pump out
feature is controlled by the switch on the top right side of the motor head. If using the pump out feature,
the pump switch can be left on.
(2) The pump is equipped with a oat switch, which will automatically start the pump when the water level in
the canister rises. The oat switch will automatically stop the pump when the liquid level drops.
(3) If the vacuum is being used without the long discharge hose, leave the pump switch o. The liquid in the
canister can also be emptied using the short, black, corrugated hose attached to the rear of the canister. Be
sure the end of the hose is securely attached to the stationary drain hose plug after use.
(4) Check the mesh bag frequently for debris. To empty, remove the bag from the canister and slide o the
retaining clip on the bottom of the bag. Reinstall the mesh lter bag before continuing to use the vacuum.
Do not operate the vacuum without the mesh lter bag in place.
CAUTION Never lubricate the vacuum cleaner motor. The motor bearings are permanently sealed. This vacuum is
intended for indoor or outdoor use and for wet pickup, but it is not intended to be exposed to rain.
