Setup And Use - Nilfisk-Advance APC 328 Information & Operating Instructions

SET-UP AND USE
1) Insert the appropriate metering tips into the chemical feed lines (see illustration, page 5).
2) Fill the holding tank with warm water (not exceeding 54 °C). Do not add any chemical to the tank.
3) Prepare the area for cleaning by emptying waste receptacles, clearing debris, removing paper
products, blowing out vents, and sweeping floors.
4) Connect the 25 ft power cord to the pig-tail on the rear of the machine.
5) PRIME THE PUMP: Attach the priming hose to the outlet quick disconnect and place the open end
of the hose into the recovery tank. Turn on the pump and let it run until the pump is completely
primed (no visible air in the water stream). Turn the pump off.
NOTE: prime the machine before you place the chemical feed tubes into chemical containers.
6) Disconnect the priming hose and attach the solution hose to the quick disconnect.
7) Attach the spray gun to the other end of the solution line.
8) Place chemicals in the molded-in chemical bottle containers on the rear of the machine. Insert one
of the feed lines into one of the chemical containers. Secure the line by screwing on the cap. The
chemical will feed from which ever container the selector valve on the switch plate is turned towards
and when the gun is used in the low pressure setting. Use chemicals with a pH of between 5 and
10. Never add chemicals to the clean water tank.
9) Set the spray gun to low pressure by sliding the pressure selector forward (low pressure = forward;
high pressure = back).
10) Turn on the pump switch (push button) and spray through the gun for a few seconds to fill the
line with solution.
11) Apply the chemical to the walls and fixtures from the bottom up. Spray the floor last as you work
your way out of the room.
12) Allow the chemical to work for the proper amount of dwell time, according to the chemical
manufacturer's directions. Agitate heavily soiled areas with a scrub brush.
13) Turn off the chemical injector valve by turning the selector to the down position.
14) Set the spray gun to high pressure and rinse the area from the top down.
15) Connect the vacuum hose, attach the squeegee, and turn on the vacuum (rocker switch).
16) Squeegee off the mirrors, pick up the liquid off the floor with the floor tool. If you have the
optional blow dry hose, use it to dry the fixtures.
17) Drain the recovered water into a utility sink or toilet. NOTE: Keep the top of the drain hose higher
than the water level in the tank to avoid uncontrolled discharge of water when you open the cap
on the hose.
CAUTION
To avoid vacuum motor damage, always use a defoamer any time foam is present.
Before you turn on the vacuum always make sure the filter screen on the ball float is clean and that the
ball can travel freely.
RE-PRIMING THE PUMP
If the pump looses prime between jobs, follow the instructions to PRIME THE PUMP, above. If that
doesn't get water flowing, put the priming hose into the vacuum inlet hose barb and cover the rest of
the space around the priming hose with your hand. Turn on the vacuum (with the pump also running)
and let the suction of the vacuum assist in getting water into the pump.
