    2.1 Pressure Adjustment: STEM Attach pressure gauge (optional) and bushing to 3/8” outlet on the head of the pump (Figure 2) . To adjust pressure, use HEX-NUT wrench to secure stem of unloader valve and prevent it from turning, adjust using wrench on 1/2” hex nut at end of spring to increase or decrease pressure (tighten to increase pres- sure, loosen to decrease pressure) .

    2.3 Product Recommendations: 2.5 Foam Adjustment: The Porta-Washer Model P is capable of dispensing liquid products. However, the most efficient type of product in nearly all high pressure cleaning applications is mild, general pur- pose cleaner which is high in wetting agent content. Acid product are beneficial in certain applications such as lime scale removal.

    Once the pumping section is disassembled carefully in- spect the following items. INLET Inspect inlet valves and inlet valve surfaces (Figure 8) . If MANIFOLD inlet valve is pitted or damaged, replace it. PISTON ROD SEAL If the major diameter of the piston next to the cup has a sharp edge or if the piston inlet surface is pitted or damaged, replace piston (Figure 11) .

    5.2 Reassembly Instructions: THERMAL After the above has been completed, it is time to reassemble OVERLOAD the pumping section. The preceding photographs and draw- SWITCH ings can aid you in reassembling the pumping section. Re- place the valve inlet, piston spacer, piston and cup, the piston retainer, cup washer, and the piston retainer nut - tighten nut snugly.

    SERVICING DRIVE BELT - MODEL P AND MODEL S Check drive belt for proper tension. Maximum deflection of belt drive, at center of span, should be 1/4”. If for any reason the pump or motor should be moved or replaced, align the pulleys using a straight edge. For proper tension and motor alignment, loosen motor locking nuts and use motor adjusting bolt on the motor base for correct positioning.

Liquid flows through outlet port and on through discharge line. Figure 22 PARTIAL BY-PASS WHILE SPRAYING: If the orifice in the spray nozzle is too small to take all of the pump’s capacity, pressure will build up in the plunger chamber.
