2.
Disconnect electrical power at the main breaker.
3.
Verify that the dedicated branch circuit for the Inline
Pressure Boosting System is equipped with a 15 amp
circuit breaker.
4.
Check that the power supply corresponds with the
electrical rating of the Inline Pressure Boosting System
being installed. Supply voltage must be +/- 10% of the
nameplate voltage.
5.
Every installation must be grounded. There must be a
reliable ground connection between the pump and the
distribution panel.
6.
The Inline Pressure Boosting System comes with all
internal connections prewired.
7.
Unit should be plugged into an outlet that matches that of
the unit purchased.
OPERATION
W A R N I N G
Hazardous Pressure: Do not run pumps
against a closed discharge, or at a system pressure above 100
psi (10 bar).
C A U T I O N
This pump has been evaluated for use
with water only.
PRIMING
Never run the pump dry. Fill the suction pipe, pump housing, and
discharge piping completely with water. A typical installation will be
supplied by either a tank or a pressurized water source, creating
what is known as flooded suction condition. The air bleed valve
can be used to evacuate the air from the pump housing. If the unit
is mounted in a manner in which the air bleed is not at the highest
point, it should be removed from the control head and installed in a
location that will allow all air to be removed from the system.
A 1/8" NPT plug will be needed to seal the port on the control head.
STARTING
All air must be removed from the system. The Inline Pressure
Boosting System comes preinstalled with an air bleed valve to
assist with evacuating the air. The orientation of the pump may
require the air bleed to be relocated.
1)
If the pump is mounted in a vertical orientation please skip
to step 6.
2)
Remove the air bleed valve.
3)
Insert a 1/8" NPT plug into the air bleed port on the
control head.
4)
Install a tee at a location that will allow all the air to be
evacuated from the pump housing.
5)
Install air bleed in tee.
6)
Close all system outlets then open the air bleed valve. Be
prepared for air mixed with some water to be discharged
through the air bleed valve.
7)
Close air bleed valve once all the air has exited the
system. The air bleed valve's discharge should be pointing
down when closed.
Once the air has been evacuated from the system, slightly
crack a system outlet. Start the pump by pressing the button.
This will put the pump into automatic mode. Immediately begin
opening the discharge valve to half open. If after a few minutes
of running you do not get water, repeat the priming process.
4
Once the pump is operating, fully open the discharge valve
and a system outlet, letting the pump operate until the water is
running clear. No further priming should be needed unless the
pump is drained or there is a leak in the suction plumbing.
LEAKY SYSTEMS
Leaky water systems may cause the Inline Pressure Boosting
System to cycle more than expected. This is due to the unit
turning on when the outlet pressure drops below 30 psi.
Continuous running or a high number of starts and stops do
not hurt the controller, pump, or motor. The issue should still
be fixed, if possible, to eliminate an increase in power usage
of the system.
ADJUSTING PUMP SO SYSTEM DEMAND IS NOT MORE
THAN SYSTEM SUPPLY
Inline Pressure Boosting Systems are typically used to increase
municipal water pressure up to 50 psi (3.45 bar) above what
is being supplied by the water utility. For the pump to operate
properly as it boosts the municipal water to the desired
pressure, a consistent and steady flow of water is required.
The system will fail prematurely if it is set to operate at a point
beyond what can be supplied.
MAINTENANCE
LUBRICATION
The pump requires only water for lubrication and should not be
run dry for extended periods.
W A R N I N G
Before disconnecting pump, be sure
power is turned off. After reassembling the pump, refer to
priming instructions before running.
W A R N I N G
Hazardous voltage can shock, burn or
cause death. Disconnect power to pump before servicing unit.
DRAINING
NOTICE: Disconnecting the pump will not necessarily drain
all other parts of the piping system. If there are any concerns
with the proper procedure or necessity of draining the suction
plumbing, contact a water systems professional.
All piping and water tanks exposed to freezing weather
should be drained. If there are any concerns with the proper
procedure to drain the system's pressure tank, contact the tank
manufacturer for assistance.
CLEANING THE FLOW SWITCH
In some cases the flow switch may become clogged or
plugged. In those cases the switch may be cleaned by the
following steps:
1)
Turn off the system prior to removing the cover.
The system may be under pressure. As such, the
pump housing should be drained prior to performing
maintenance on the flow switch.
2)
Remove cap by removing the six Phillips screws that hold
the cap in place.
3)
Remove the three Phillips screws that hold the flow control
cap in place.
4)
Remove the flow control cap.
5)
Use a metal object, such as a screwdriver, to retrieve the
magnetic flow control piston from the cavity.
6)
Clean the magnetic flow control piston with a cloth.
7)
Clean the flow tube before reassembly.
