SAVE THESE INSTRUCTIONS

INSPECTION:

Carefully unpack and inspect your APC 328 for shipping damage. Each machine is tested and inspected before shipping. Any shipping damage

incurred is the responsibility of the carrier. You should notify the carrier immediately if you notice damage to the box or to the machine or parts.

CLEANING SOLUTIONS:

We recommend liquid cleaning chemicals. Powder chemicals may be used, but unless mixed very thoroughly they could cause a build-up in the
pump, lines, heat exchanger and/or quick disconnects. Any problem caused by a chemical build-up is not covered by warranty. Use a neutral
cleaner with a pH between 5 and 10 to avoid premature wear of the pump, seals, and/or other components.

MAINTENANCE:

For optimum performance fl ush the machine with clear water at the end of each working day. Once a month, minimum, run a fl ushing compound
through the machine to break up any mineral or chemical build-up that may have formed. The vacuum motor and the pump do not require any
scheduled maintenance; however, the motor may require replacement brushes after 1000 - 1500 hours. Clean the body with an all-purpose
detergent, and protect it with an automobile interior polish. Lubricate the wheels, castors, and quick disconnects with an all purpose silicone
spray. Refer to the maintenance schedule on page 9.

PARTS AND SERVICE:

Repairs, when required, should be performed by your authorized distributor who maintains an inventory of original replacement parts and
accessories. Call the distributor from whom you purchased this machine if you need parts and service. Be sure to specify the machine model.
Have your serial number at hand.

KNOW YOUR MACHINE

Operator Handle (1): Operator holds onto this handle to move the machine from one location to another.
Solution Tank Lid (2): This lid screws off so the tank can be fi lled. The solution fi ll hose is tethered to the lid, and hangs inside the arm of the

Operator Handle.

Maid’s tote and Recovery tank lid (3): This removable container holds often-used items and has a handle for easy carrying. The recovery
tank lid sits under the maid’s tote and covers the opening in the Recovery Tank. This is where the operator can access the tank to clean it
and the ball fl oat cage. The tank can be fl ushed out by running clean warm water into this opening and laying the open drain hose into a
bucket or drain.

Recovery Hose (4): Waste water is picked-up through this hose.
Spray Hose (5): This hose delivers water from the machine to the cleaning tool.
Drain Hose (6): This hose is used to empty the recovery tank. NOTE: hold the end of the hose above the water level in the tank to avoid

sudden, uncontrolled fl ow of waste water when you remove the cap, then lower the hose slowly to control the rate of discharge.

Quick Disconnect (7): Point of attachment for the Spray Hose (5).
Castors and Wheels (8): Castors pivot for ease of steering, and large back wheels make it easy to roll the machine from location to

location.
Chemical Feed Lines (9): These clear tubes connect the cleaning chemical containers to the machine where the chemical can be
siphoned into the outlet water from the pump. Metering tips -- used to change the ratio of water to chemical -- are installed here.
Switch Plate (10): The machine’s on/off switches for the vacuum and for the pump are located here and this is where the valve to change
chemical feeds is located.

Power Cord (11): The 25 ft. power cord connects to a power cord pigtail on the rear of the machine.
Chemical Container Holders (12): Two molded-in bottle holders for chemical jugs.
