Maintenance Program

1. Filter: Follow the manufacturer’s instructions for disassembling filter. Remove

dirty filter bag and replace with clean bag. Do not allow adhesive to dry.

Reassemble filter immediately.

2. Pump: To remove pump from system for cleaning, disconnect fluid line at outlet

of pump and insert threaded plug into fluid line to prevent drying of adhesive.

Remove suction line from adhesive and place in 5 gallons of soapy water.** Flush

through the pump. Disconnect siphon line at inlet to pump and invert pump to

allow water to drain out. Follow disassembly instructions to remove manifold,

diaphragms and valves. Soak these parts in 3M™ Adhesive Remover or

equivalent until adhesive has been sufficiently loosened and can be rubbed off.*

Dry parts overnight at room temperature or 2 to 3 hours at 120°F (49°C) before

reassembling pump. Do not install parts until all odor is gone. If pump must be

returned to service quickly, a second set of diaphragms and valves should be

purchased and installed while the first set is being cleaned. To put the pump back

into operation, follow steps 6 through 12 in Start-Up Procedure.

3. Spray Applicator: Should the fluid tip become plugged, shut off pump by

reducing inlet air pressure to “0” psi, or disconnect inlet air. Manually trigger

applicator to relieve pressure in fluid lines. Remove tip, wipe any particles from

fluid needle with damp cloth and immediately install a clean fluid tip. (Note: Fluid

tips must be stainless steel.) Do not allow adhesive to dry in applicator or tip.

Plugged tip may be rinsed in water and soaked in mineral spirits, followed by

brushing with stiff bristle brush to remove adhesive. Air caps which become

coated with adhesive should be replaced with clean caps. Soak adhesive coated

caps in mineral spirits to clean.*

*When using solvents, extinguish all ignition sources, including pilot lights, and

follow the manufacturer’s precautions and directions for use.

**Cleaning solution: One pint cleaner to five gallons of water. Flush with clean

water.

Attention:

1. Do not use fluid lines that have previously been used with solvents whether

flammable or non-flammable.

2. Do not use “rubber” lined hose. Hose should be either flexible polyethylene

or nylon lined. All hose and pipe fittings should be plastic or stainless steel.

DO NOT use copper, aluminum, brass or steel fittings.

3. A pressure pot may be used in place of the pump. In this case, a polyethylene

bag liner should be used. Also the DIP TUBE AND FITTINGS SHOULD BE

CHANGED TO PLASTIC OR STAINLESS STEEL.
