(Appendix 2) to determine the amount of head lost for a
given application.
PRESSURE TANK
The Inline Pressure Boosting System needs a small pressure
tank placed on the pump outlet to reduce cycling. The pressure
in the tank should be set to 28 psi. The tank supplies water in
circumstances where only a small amount of water is required for
a short period of time. In addition, the tank prevents water hammer
by acting as a system buffer. This buffer also helps to prevent
pressure spikes when there is a sudden change in demand.
INSTALLATION
NOTICE: Read and follow all instructions
W A R N I N G
Hazardous voltage can shock, burn, or
cause death.
C A U T I O N
Improper wiring can result in permanent
damage to the system. Pump connection must comply with
National Electrical Code (NEC) or Canadian Electrical Code
(CEC), and all applicable local codes.
C A U T I O N
If you are not sure of the proper electrical
connections, employ a competent electrician for the installation. This
ensures the installation complies with all noted electrical codes.
Disconnect power at electrical panel before making any
electrical connections. Supply voltage must be +/- 10% of Inline
Pressure Boosting System nameplate voltage.
Low or high voltage can damage the Inline Pressure Boosting
System and will void the warranty. Connect pump to a
dedicated branch circuit with no other appliances on it.
Do not operate pump unless pump is grounded.
A fused disconnect switch or circuit breaker should be
placed at or near the pump as required by local electrical codes.
TYPICAL INSTALLATION
The Inline Pressure Boosting System is designed to increase a
system's usable pressure whenever water is in use. See Figure 1
for a graphical representation of what a typical installation may
look like.

INSTALLATION PROCEDURE – PLUMBING
1.
Disconnect electrical power at the main breaker.
2.
Drain the system (if applicable).
3.
Mount the Inline Pressure Boosting System in the desired
location using mounting screws and mounting holes. The
mounting screws are not included with the product. The
Inline Pressure Boosting System may be installed in a
horizontal or vertical orientation but must not be inverted
or hung from a horizontal surface.
4.
Install inlet and outlet plumbing and pressure tank as
shown in Figure 1. The inlet and outlet of the unit is
marked with "inlet" and "outlet" respectively. Unions on the
suction and discharge ends of the pump should be used.
Internal check valves are provided on both the suction and
the discharge ends of the pump. These valves can help in
preventing backflow. If the optional bypass loop is used, a
check valve should also be installed before the bypass. Be
sure to check all local plumbing codes to ensure that all
requirements pertaining to backflow prevention are met.
5.
Install the pressure tank downstream from the pump. The tank
should be located within 5' of the discharge of the pump.
6.
Install a pressure relief valve downstream of the check
valve. The discharge must be plumbed to a drain rated for
maximum pump output at relief pressure settings.
W A R N I N G
develop very high pressure in some situations. Always install a
pressure relief valve able to pass full pump flow at 120 psi (6.9
bar). Install the pressure relief valve near the pressure tank.
C A U T I O N
can develop very high pressure in some situations. It might
be necessary to install a pressure reducing valve to limit the
potential boost. Install the pressure reducing valve after the
pressure tank.
INSTALLATION PROCEDURE – WIRING
1.
Employ a licensed electrician to perform the wiring.
All wiring must be done in accordance with applicable
national and local electrical codes.
