NOTE: Installation of a low pressure safety cutoff switch
on the pump discharge is recommended (and may be
required by your local code) to shut off the power in case
of low discharge pressure (caused by broken pipe, etc.).
2. Mount the pump on a solid base in the location you have
decided on.
3. Choose a time that will allow you to shut off the water to
the household while you install the Pressure Booster
System.
4. Shutoff the main water supply valve to the household.
5. Open any faucet to relieve water pressure in the plumbing.
Once the water pressure is relieved, close the faucet.
6. READ STEP 6 COMPLETELY BEFORE STARTING TO WORK ON
IT. You must remove a length of pipe from the main water
supply line to allow installation of elbows for the Pressure
Booster System. The locations of the cuts must take into
consideration the size of the elbows being used, the
length of the threads in threaded joints or the overlap in
glued or soldered joints, etc. Position the elbows in line
with the pump suction and discharge threads. There may
be slight water leakage while cutting the pipe. Remove
any burrs or shavings caused by the cutting tool.
NOTE: Galvanized pipe may not need to be cut. If there is
a union close to the pump location, disassemble the union
and remove (unscrew) pipe back past the pump location.
Have new lengths of pipe cut and threaded to allow for
the pump installation.
NOTE: Both female suction and male discharge ports have
1" NPT threads. Depending on your type of connection and
the size of your home's piping, you may need to install
adapters on the ports.
7. Once the short piece of pipe is removed, the piping above
the cut can be drained to prevent water mess. Place a pail
under the opening going to the household. Open the high-
est faucet in the system to let in air so the water can fall
out of the pipes into the pail. Once it's drained, close the
faucet.
8. Install the elbows in the main water supply line. Point
them toward the pump.
Risk of burst hose and flooding. Do not
install with flexible hoses. Use only rigid piping that meets
code.
9. Install piping from elbows to pump including a union in
each line and a check valve in the pump suction line. The
arrow on the check valve must point to the pump suction
(see Figure 2). If not already in the plumbing system,
install a pressure relief valve in the pump discharge line
capable of passing the full pump flow at 100 psi (689
kPa). If local code requires installation of a pressure relief
valve capable of handling the full pump flow at a pressure
less than 100 psi (689 kPa), follow the code requirements.
A low pressure safety cutoff switch should also be installed
in the discharge line, and may be required by your local
codes.

10. With all pipe and fittings installed and sealed, turn on
the main water supply slowly to pressurize the system
and check for leaks. If any leaks appear, turn the main
valve off, open a faucet to relieve the pressure, and repair
the leak. Repeat this step until there are no leaks in the
system.
11. Open a faucet to release the air from the pipes and allow
water to flow. When a steady stream of water flows out of
the faucet, the pump is full of water and fully primed.
Close the faucet.
12. Turn the controller knob to the desired pressure for the
pump to turn on. The Pressure Booster System comes fac-
tory preset at 30 psi (207 kPa), and we recommend start-
ing there and adjusting it later according to your experi-
ence with the system.
13. Before continuing with the installation, see the sections of
this manual titled "Electrical Connections", "Automatic
Pressure Controller", "Normal Operation", and "When Does
The Pump Stop Operating" for detailed information on how
the system functions.
14. At this point, you can plug in the pump for the first time.
When you plug in the power cord, the pump will start and
run for 15 seconds regardless of the controller setting. If
the inlet pressure is above the set point, the pump will
stop after 15 seconds.
15. When the pump is running and after it shuts off automati-
cally, the system is at the boosted pressures. Inspect the
pipe and fittings again for water leaks. If any leaks
appear, unplug the pump, turn the water main valve off,
open a faucet to relieve the pressure and repair the leak.
Repeat this step until there are no leaks in the system.
