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 3075SS.
4. Shutoff the main water supply valve to the household.
5. Open any faucet to relieve water pressure in the plumb-
ing. 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 3075SS. The locations of the cuts must take into con-
sideration 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 connec-
tion 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 highest 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. See Figure 4.
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 sys-
tem, 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 pres-
sure less than 100 psi (689 kPa), follow the code require-
ments. 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 sys-
tem.
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 3075SS comes factory preset at 30
psi (207 kPa), and we recommend starting there and
adjusting it later according to your experience 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.
