50 PSI MAXIMUM or loss of efficiency and motor over
heating will result. IMPORTANT: After any change to your
cut in pressure, you need to readjust the pressure tank
pre charge.
lf you are raising water vertically AND pressurizing.
Example: A pump that lifts 3 m / 10 vertical feet and
pressurizes to 2.1 bar/30 PSI must pump a total of 2.4
bar/35 PSI.
Total lift = vertical distance from water surface to
pressure tank.
INSTALL THE PRESSURE RELIEF VALVE near your
pressure tank (at the "Accessory Tee" shown in dia-
gram). Run a pipe or hose from its outlet to a drain or
drain pipe or to the outdoors where water can drain
away safely.
A GATE VALVE and DRAIN VALVE are recommended
(see diagram) for convenience during system shut
down. The drain valve is simply a garden hose outlet
which allows easy draining of the system. It also allows
water delivery by hose while water is shut off to the
house during installation or repairs to plumbing.
INSTALLATION KIT IS AVAILABLE! lf you have not yet
purchased the small parts you need to install your
Booster Pump, you can save time and confusion by
purchasing our convenient parts kit. All components are
selected for maximum quality and convenience.
12 MAINTENANCE
INTERNAL INTAKE SCREEN: The pumps of Series 1300
have an internal metal intake screen. Its purpose is to
catch solids accidentally introduced during installation
or filter servicing, dirt stuck inside your intake pipe
before installation, or mineral deposits that may
accumulate and flake off of the intake piping. 1300
SERIES "PS150 BOOST" has an angled extension with
a large brass nut on the end. Remove the nut to inspect
and empty screen.
EXTERNAL FILTRATION IS STILL REQUIRED! lf you
notice signs of intake blockage, inspect your screen. lf
solids keep accumulating, improve your filtration. See
Page 6 for details about filters and cartridges.
PUMP HEAD: Except for the internal screen, your pump
head is maintenance free. DO NOT remove its front
plate or otherwise tamper with it unless you are
11.1 Pressure Switch Wiring
1. Connect to Float switch
terminal 4 of PS Controller
2. Connect to float switch
terminal 5 or 3 depending of
NC or NO function
3. Setting of cut-in pressure
4. Earth terminals
5. Setting of pressure differ-
ential
You can also use the pressure switch to switch the
main power supply of the pump. But the recommendet
way is to avoid any switch power losses and to use the
float switch terminals of the PS controller to start and
stop the pump
WARNING: INSTALL THE PRESSURE
RELIEF VALVE INCLUDED WITH YOUR
PUMP! Some PS150 BOOST Pumps for
city water pressure systems are supplied
with a 6 bar / 85 PSI Pressure Relief Valve
as a safety feature. lf your pressure switch fails,
EXCESSIVE PRESSURE may cause your tank of piping
to burst and flood your home.
intending to get it rebuilt. The pump head is NOT USER
SERVICEABLE. It is easy to disassemble, but difficult to
reassemble without special tools.
WATER FILTER: KEEP SPARE CARTRIDGES! lf you
cannot obtain suitable cartridges locally, ask your
dealer, or the factory. The best way to determine when a
cartridge is becoming clogged is to listen for an
increasingly loud buzzing noise (cavitation). It is difficult
to determine the condition by the appearance of the
cartridge.
30" INTAKE FILTER, WARNING: Cartridges vary slightly
in outside diameter. If replacement fits loosely into end
caps, wrap ends with cloth or tape to make a snug fit. lf
cartridge is too large to fit, peel away some fibers using
a knife. End caps MUST fit snugly or dirt will enter!
Pressure Setting
Completely release nut for
setting of differential (5).
Adjust nut (3) until required
cut-in pressure is obtained.
Tighten nut (5) until required
cut-out pressure is obtained.
You need a pressure gauge
to find the right setpoints for
your application.
