PREVENTIVE MAINTENANCE CHECKLIST
Keep Water Out
Water tends to collect in storage tanks. This is due to moisture-laden air being drawn into the
storage tank and condensing, or to defective fill openings that are not properly protected with
watertight covers. Storage tanks should be checked after every fill-up for water and removed with
a sump pump, to forestall serious damage to equipment. Water, sediment, and other foreign
matter that accumulates in the tank can be drawn up into the pump and cause failures.
Lubricate the Pumping Unit
The pumping unit should be lubricated every six months or every 100,000 gallons. Do this by
applying a few drops of a light grade oil (SAE 10) to the felt pad located on the pump body slightly
above the shaft which connects to the pump pulley. Oil used should be suitable for temperatures
ranging from -40 F to 180 F.
Clean the Dial Face
Clean the dial face with a soft, clean, damp cloth as often as necessary.
Clean the Strainer
Clean the strainer immediately after the pump has been installed and tested, and again after a few
hundred gallons have been delivered. Thereafter, once every six months, or as required.
The symptoms of a dirty or clogged strainer in a pump are slow delivery, noisy operation, and
pulsation. To clean the strainer, turn off AC power to the pump. Locate the Suction Strainer Cap
on the plumbing unit and unscrew it to access and remove the strainer. Use compressed air
* to
blow the dirt out of the strainer.
*Wear protective safety goggles or glasses when using compressed air.
Change the Filter
If the unit is equipped with a filter, check and change it at regular intervals. A dirty filter in a pump
will cause a slower delivery rate. Refer to the accessories section of your parts manual to ensure
that you replace the filter with one designed for your model. Always use a drip pan directly below
the filter when removing the cartridges to prevent contamination of both the soil and the electrical
components within the cabinet.
Adjust the Belts
With the proper care, belts will give exceptionally good service. A loose belt not only cuts down
dispensing speed, due to slipping, but also results in excessive wear. A properly tightened belt will
allow twisting the belt 180 degrees midway between the motor and the pump pulleys.
On the 9822A and 9823A models, the belt can be tightened by loosening the cap screw which
holds the idler arm and sliding the arm to obtain the correct belt tension of 6 3/4 lbs (+ 3/4). When
the adjustment is complete, remember to retighten the cap screw.
