9. Turn on booster pump.
10. At pool side, read the pressure gauge installed on
cleaner hose. Pressure should be set (see Table
1) for the length of hose in your pool.
11. If the pressure is too low, replace the speed
adjustment washer with "D" or "E" speed adjust-
ment washer (follow steps 1-10). Each letter up
will increase pressure approximately 2 psi.
12 If the pressure is too high, replace the speed
adjustment washer with "A" or "B" speed adjust-
ment washer (follow steps 1-10). Each letter
down will decrease pressure approximately 2 psi.
13. When the Ray-Vac speed is properly adjusted,
turn off all pumps.

case from the pool wall. Unthread the quick
disconnect fitting from the filter screen case.
Remove the washer and speed adjustment disk.
Place the washer back into the quick
disconnect fitting.
15. Unthread the filter screen case from the end of
the hose. Thread the quick disconnect fitting back
onto the hose end (see Fig. 6).
16. Push the quick disconnect fitting into the pool wall
fitting.
17. Shake the water out of the pressure gauge and
store the unit for future adjustment (if necessary).
