GROUNDING INSTRUCTIONS
STAY ALERT! Watch what you are doing and use
common sense. Do not use vacuum cleaner
when you are tired, distracted, or under the
use of drugs, alcohol or medication causing
diminished control.
This appliance must be grounded. If it should
malfunction or breakdown, grounding provides a path
of least resistance for electric current to reduce the
risk of electric shock. This appliance is equipped with
a cord having an equipment-grounding conductor
and grounding plug. The plug must be inserted into
an appropriate outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
WARNING: Improper connection of the
equipment-grounding conductor can result in
a risk of electric shock. Check with a qualified
electrician or service person if you are in
doubt as to whether the outlet is properly
grounded. Do not modify the plug provided
with the appliance—if it will not fit the outlet,
have a proper outlet installed by a qualified
electrician.
1. This appliance is for use on a nominal 120-volt
circuit, and has a grounded plug that looks like the
plug illustrated in sketch A. (See Figure 1)
2. A temporary adapter, like the adapter illustrated
in sketches B and C, may be used to connect this
plug to a 2-pole receptacle (as shown in sketch B)
if a properly grounded outlet is not available. (See
Figure 1)
Figure 1
3. The temporary adapter should be used only until a
properly grounded outlet (sketch A) can be installed
by a qualified electrician. The green colored rigid
ear, lug or the like extending from the adapter must
be connected to a permanent ground such as a
properly grounded outlet box cover. Whenever the
adapter is used, it must be held in place by a metal
screw. (See Figure 1)
NOTE: In Canada, the use of a temporary
adaptor is not permitted by the Canadian
Electrical Code. Make sure that the appliance
is connected to an outlet having the same
configuration as the plug. No adapter should
be used with this appliance.
EXTENSION CORDS
When using the appliance at a distance where an
extension cord becomes necessary, a 3-conductor
grounding cord of adequate size must be used for
safety and to prevent loss of power and overheating.
Use the table below to determine A.W.G. wire size
required. To determine ampere rating of your vacuum,
refer to nameplate located on rear of motor cover.
Before using appliance, inspect power cord for loose
or exposed wires and damaged insulation. Make any
needed repairs or replacements before using your
appliance. Use only three-wire outdoor extension cords
that have three-prong grounding-type plugs and three-
pole receptacles that accept the extension cord's plug.
When vacuuming liquids, be sure the extension cord
connection does not come in contact with the liquid.
PAGE 2 OF 25 0115 IH -2603
NOTE: Static shocks are common in dry areas
or when the relative humidity of the air is low.
This is only temporary and does not affect the
use of the appliance. To reduce the frequency
of static shocks in your home, the best remedy
is to add moisture to the air with a console or
installed humidifier.

OPERATION
WET PICK-UP
See the Shop-Vac® vacuum filter guide on page 4 to
determine which type of wet filtration is best for your
needs. Remove the dry filters plus all dirt and debris
found in the tank assembly. Wet pick-up requires only
the foam sleeve OR cartridge filter to be in place.
Do not use dry filters for wet pick-up. When picking
up several tanks full of liquid, the filter will become
saturated and misting may appear in the exhaust air.
At this time, you should dry the filter or change to a dry
filter to eliminate the misting and possible dripping of
liquid around the lid. After completing a wet pick-up
job, raise the hose to drain into tank before shutting off
the vac. The interior of the tank should be periodically
rinsed clean.
NOTE: Wet pick-up accessories should be
washed periodically with soap and water,
especially after picking up wet, sticky liquids.
DRY PICK-UP
See the Shop-Vac® vacuum filter guide on page 4 to
determine which type of dry filtration is best for your
needs. Better quality filtration is required for finer dry
materials. Collection filter bags are recommended for
very fine materials such as dry wall dust.
NOTE: When using the vacuum to pick up very
fine dust, such as sawdust or dry wall dust, it
will be necessary to empty the tank and clean
the filter at more frequent intervals to maintain
maximum pick-up power or upgrade to
collection filter bags.
KEEP FILTERS CLEAN
installing it. Check the filter for tears or small holes. Even
a small hole can cause dust to be exhausted. Do not
use a filter with holes or tears. Replace it immediately.
INSTALLING AND CLEANING THE CARTRIDGE
1. Slide cartridge filter down over filter cage.
(See Figure 9)
2. Place filter retainer on top of cartridge filter.
(See Figure 10)
3. Hold onto base of lid cage with one hand and turn
retainer clockwise to tighten. (See Figure 11)
4. To remove filter for cleaning, hold onto base
of lid cage with one hand and turn retainer
counterclockwise to loosen. (See Figure 12)
5. Slide cartridge filter off filter cage. (See Figure 13)
6. Clean wet filter by rinsing from the inside. (See Figure 14)
7. Clean dry filter by tapping it on inside of waste can.
(See Figure 15)
8. When wet (to prevent mold and/or mildew buildup), the cartridge filter should be removed and
allowed to air dry for a 24-hour period before being
re-installed back onto the filter cage.

The efficiency of these vacuum cleaners is largely
dependent on the filter. A clogged filter can cause
overheating and possibly damage the vacuum
cleaner. Clean or replace filters regularly. Do not use
the vacuum or filters for collecting hazardous or other
health endangering materials.
NOTE: Never machine wash or dry filters.
BLOWER USE
The H-2603 and H-2604 Shop-Vacs® can be used as
powerful blowers by inserting the hose into the motor
housing exhaust port. To use as a blower:
CARTRIDGE FILTER MAINTENANCE
This filter is made of high-quality paper designed to stop
small particles of dust. The filter can be used for wet
or dry pick-up. A dry filter is necessary to pick up dry
material. If you use your vac to pick up dust when the
filter is wet, the filter will clog quickly and be very difficult
1. Clear hose of any obstructions.
2. Insert hose end into blower port on rear of unit. Twist
slightly to tighten.
3. Caution should be used when using attachment

to clean. The filter may become saturated when picking
up large quantities of liquid, causing misting to appear
in the exhaust air. At this time, you should dry or change
the filter to eliminate this occurrence. Please handle the
filter carefully when removing it for cleaning or when

IH-2603-SPFR.indd 59/16/19 2:47 PM
OPERATION CONTINUED
AUTOMATIC SHUTOFF
The vacuum cleaner is equipped with an automatic
shutoff that operates when picking up liquids. When the
liquid in the tank reaches a certain level, an internal
float will seat itself against a seal at the intake of the
motor, shutting off suction. When this happens, the
motor will develop a higher than normal pitch noise
indicating that you need to shut off the vacuum and
empty the liquid.
NOTE: If accidentally tipped over, the float
shutoff device could seat against the seal and
shut off suction. If this happens, simply place
the vacuum cleaner in upright position and
turn off the switch until the float returns to its
normal position.
EMPTYING THE TANK
CAUTION: Use special care when emptying
heavily loaded tanks.
The wet/dry vacuum may be emptied of liquid waste
by removing the tank cover. To empty, switch off the
vacuum and remove the plug from the wall receptacle.
Remove the tank cover and empty the tank.
NOTE: Tank can also be emptied by removing
drain cap and draining liquid waste into a
suitable drain.
STORAGE
Before storing the vacuum cleaner, always empty and
clean the tank. Never allow liquids to sit in the tank for
any extended period of time.
NOTE: Always store the vacuum cleaner indoors.
LUBRICATION
No lubrication is necessary as the motor is equipped
with lifetime lubricated bearings.
MAINTENANCE
WARNING: Be sure to disconnect power supply
before attempting to service or remove any
components.
SERVICE
Do not attempt to service your Shop-Vac® wet/dry
vacuum cleaner beyond that described in these
instructions. Refer all other servicing to Uline Customer
Service.
