Installation Recommendations; Check The Water Flow - Polaris PB4-60 Installation And Operation Manual

3.3.4 Install the Pump
1. Mount the pump using two (2) concrete expansion
anchors to ensure stability.
2. Apply four (4) to six (6) wraps of Teflon® tape
to the tapered thread of the connecter barb. See
Figure 5 (a).
CAUTION
Pipe dope should NEVER be used on barb threads.
Pipe dope will severely weaken the plastic, causing
leakage and may cause the plastic to fracture. DO
NOT OVERTIGHTEN.
3. Thread and tighten the tapered thread of the
connector barb into the pump port on the pump
body. See Figure 5 (b).

4. Trim reinforced hose to required length. Make sure
cut is clean and square. Avoid unnecessary loops
or bends in the hose.
5. Slide connector nut onto the trimmed end of the
hose with threaded end toward the cut end of the
hose. See Figure 5 (c).
6. Apply water to connector barb to help hose slide
over barbs. Push trimmed edge of hose fully onto
the connector barb. See Figure 5 (d).

7. Slide/Rotate the connector nut to the barb to
engage threads correctly, do not cross thread
connector nut. Tighten the connector nut until
threads are no longer visible (gap about 1/8" or
just less than the width of two dimes), or until it
touches the barb face. See Figure 6.

3.3.5 Installation Recommendations

1. If the pump is located below water level, isolation
valves must be installed on both sides of the pump
to prevent back flow of pool water during any
routine or required servicing.
2. To help prevent difficulty in priming, install the
suction pipe without high points (above inlet of
pump - inverted "U"s in plumbing), which can trap
air.
3. The piping must be well supported and not forced
together where constant stress will be experienced.
4. Always use properly sized valves. Jandy

have the best flow capabilities.
5. Use the fewest fittings possible. Every additional
fitting has the effect of moving the equipment
farther away from the water.
NOTE If more than 10 suction fittings are needed, the
pipe size must be increased.

3.3.6 Check the Water Flow

NOTE This pump must have minimum outlet pressure
of 45 psi. Lower pressure may cause an over-
current motor condition.
After the system is plumbed, verify water flow to
the booster pump by disconnecting the inlet supply line
at the booster pump and then turning on the filtration
pump. Water should flow from the line.
