INSTALLATION
3.3
Tubing Connections
Use only LMI tubing.
DO NOT USE CLEAR VINYL TUBING ON THE DISCHARGE SIDE OF THE
PUMP. The pressure created by the pump can rupture vinyl tubing, which is only for
connection to the return line of the FastPrime
™
fitting.
Before installation, all tubing must be cut with a clean square end.
Valve and head connections from the factory are capped or plugged to retain pre-prime
water. Remove and discard these caps or plugs before connecting tubing.
DO NOT USE PLIERS OR PIPE WRENCH ON COUPLING NUTS OR FITTINGS.
To assemble tubing into the fittings:
1. Put coupling nut over tubing.
