Adjust Flow
1. With the main drain closed, and one end of the hose attached to
the vacuum regulator installed in the skimmer, while keeping the
hose under water, remove the cleaner and insert the flow indicator
into the end of the hose.
2. Keep the hose and flow indicator underwater.
3. Turn on the pump. With the pump running, adjust the vacuum
regulator (in your skimmer) until the disk on the flow indicator is
between minimum and maximum flow, see Figure 8.
4. Use the vacuum regulator in conjunction with your pool cleaner
system at all times. The vacuum regulator has an adjustment knob,
see Figure 9. If suction is too high, the knob is turned
counterclockwise to decrease the suction. If the suction is too
low, the knob is turned clockwise to increase the suction.
NOTE:
The flow indicator is calibrated for use with the “Y”
shaped vacuum regulator valve. The flow indicator will not
indicate the correct flow for the cleaner if you are not using
the “Y” shaped vacuum regulator valve.
5. Remove the flow indicator from the end of the hose and attach
the hose to the cleaner’s swivel, see Figure 6 on page 9.
Too much Vacuum/Flow?
You have too much vacuum if the cleaner sticks to the pool bottom or moves slightly or not at all or if the
cleaner climbs up the pool wall past the water line to the point that the cleaner sucks air and the pump
loses prime. Frequent loss of prime will damage the pump. To correct this, adjust the regulator by turning
the adjustment knob counterclockwise. This will decrease the suction.
Not enough Vacuum/Flow?
You don’t have enough vacuum if the cleaner moves sluggishly, or not at all. Be sure the filter system is
clean and the vacuum regulator and all valves are adjusted to give you maximum vacuum. If the cleaner
is still not moving, your pump may not be strong enough to operate the cleaner. Please refer to the
“Troubleshooting Section” on page 12.
V. Adjustments
After completing the installation,
turn the pool pump on.
Allow the pump to run for a couple of minutes
to allow air to cycle out of the system. E-Z Vac
®
should be moving about the pool at a rate of 8 to 12 feet
per minute. Check each of the following initial adjustments to E-Z Vac
®
at this time.
Hose Length
IMPORTANT:
The pump must be on when you check the hose length. The hose contracts when the
pump is operating and will look longer when the pump is off.
Position the E-Z Vac
®
at the furthest point of the pool from the skimmer. (It is easy to position E-Z Vac
®
in the pool by moving it about with your pool pole and brush.) E-Z Vac’s hose should be long enough to
reach to the end of the pool, plus one hose section. If necessary, remove extra hose sections from the
center portion of hose. Removing center hose sections avoids having to disturb the hose weight placement.
Save extra hose sections for use as needed for replacement.
Return Line Water Flow
IMPORTANT:
The water flow from your return line can push the cleaner’s hose and affect its
performance. It may cause the cleaner to steer away from the end of the pool where the return line is
located, or it may cause it to remain in one section of the pool. To correct this, use the eyeball diverter
included with your cleaner.
