4. INSTALLATION
Materials
-
1 diaphragm pump with related accessories
-
2 (at least) pieces of flexible, reinforced hose piping, with collapsing
strength of twice the inlet collapsing pressure, hose must be mini-
mum 1/2” ID
-
4 stainless steel hose clamps and screws
-
4 screws to fasten the pump to the mounting surface
-
1 electrical cutoff switch
-
1 fuse
-
1 screwdriver
-
1 strong, cutting implement for tubing
-
Teflon tape or sealant (if desired)
Setup
1. The pump may be mounted in any position. If mounted vertically, the
pump head should be in the down position to avoid leakage into the
motor casing in the event of a malfunction.
2. Secure the feet, but do not compress them. Over-tightening the se-
curing screws may reduce their ability to dissipate noise and vibra-
tion.
3.
Intake hose must be minimum ½” (13 mm) ID reinforced hose. Main
distribution line from pump outlet should also be ½” (13 mm) ID with
branch and individual supply lines to outlets no smaller than ⅜” (10
mm).
4. Plumb the system using high pressure (2 x pump rating) braided,
flexible tubing to minimize vibration/noise.
5.
Do not apply inlet pressure in excess of 30 PSI. In general, try to
avoid any inlet pressure completely.
6.
Avoid any kinks or fittings which could cause excessive restrictions.
7. Strainer should be attached to the inlet side.
8.
The fittings must be secured to avoid leakage.
9. Use clamps at both ends of hose to prevent air leaks into the water
line.
10.
If a check valve is installed in the plumbing, it must have a cracking
pressure of no more than 2 PSI.
11. If applying a sealer or plumbing tape, be careful to not over-tighten,
as they may be sucked into pump.
12. This pump should be wired on its own dedicated circuit. Connect
the positive lead (red) to the positive terminal of the battery and the
negative wire (black) to negative terminal of the battery.
13. In an easily accessible location, install a switch to control electricity
to the pump. Turn the pump off when not used for extended periods
or when the tank is empty.
14. The electrical circuit should be protected with an over-current protec-
