1. Disconnect power to the filtration system at the breaker.
2. Install a 2" PVC tee downstream from the filter and
upstream from any sanitation or chlorination equipment.
See Figure 7.
3. Connect one leg of the tee to the pool return line.
4. On the open leg of the tee install a PVC 2" to 3/4"
NPT reducer bushing. Be sure to use approved PVC
cement. DO NOT INSTALL with open leg facing up.
See Figure 7.
CAUTION
The pump is not self priming and must be filled
with water from an upstream filter pump. Never
run the booster pump without water. Running the
pump "dry" for any length of time can cause severe
damage to both the pump and motor and will void
the warranty
WARNING
PVC cement and primer can produce vapors that
can be hazardous to your health. Use PVC cement
to join pipes only in a well ventilated area where
vapors cannot accumulate.
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

5. Apply 4-6 wraps of PTFE (Teflon™) tape to the tapered
threads on all four of the barbed fittings. Be sure to wrap
the tape in the opposite direction that the male threads will
be turning in order to create a water tight seal. See Figure 9.
6. Install the quick connect barbed fitting into the
reducer bushing.
7. Cut the reinforced hose to length. Make sure the cut is
square and clean.
8. Slide the quick connect nut over the reinforced hose.
See Figure 9.

10. Slide the hose over the barbs until a snug fit is achieved.
See Figure 8.
