PREVENTIVE MAINTENANCE
Note: Re-read Chapter 1 “Safety Precautions” before performing any maintenance procedures. All
maintenance procedures must be performed by qualified, trained technicians.
General Cleaning
The D15/D25/D45 SERIES ASU enclosure is f inished with an extremely durable polyurethane
paint. The enclosure may be cleaned with a variety of industrial cleaners f ollowing manufacturers’
directions. To prevent discoloration or deterioration of the ASU’s finish, avoid prolonged contact
with strong solvents.
The molded plastic lid and control and hose panels may be cleaned with mineral spirits.
Preventive Maintenance Schedule
The ASU requires little maintenance. The hopper is fitted with a coarse screen to prevent large de-
bris from entering the system. Normally this screen does not require cleaning. The ASU parts that
require regular, periodic maintenance are as follows:
Output Filter
The output (pump) filter should be replaced monthly during the first few months of operation. After
you gain experience with your system, you can determine how often you need to replace it. The out-
put filter is located on the output filter manifold on the hose connection panel of the ASU. See il-
lustration of the output filter on page 6-2.
Use the following procedure to replace the output filter.

Failure to wear a face shield or safety glasses could result in severe eye injury
during these procedures. Protect yourself from potential burns by wearing
insulated gloves and arm guards.

performing any pump filter maintenance. See page 6-5 for detailed instructions.
HOT ADHESIVE
Avoid splashing hot adhesive. The filter screen will be covered with hot
adhesive and must be h andled with proper t ools. Position a heat-resistant
