factory pressure setting, the pump will
be in stand-by mode (green LED ON),
ready to start if the pressure decreases.
The pump should start immediately
when the pressure drops below the
set-point and pressure should return
to the set-point and stay there. Do not
run the pump with the discharge shut-
off valve closed! If the system goes to
PROTECTION mode, refer to the "Quick
Troubleshooting Guide".
MAINTENANCE
Hazardous voltage.
Can shock, burn, or kill. Before doing
any work on the pump or the VFD,
disconnect all power from the VFD and
wait 5 minutes for the VFD capacitors to
discharge. See "Electrical Safety" and
"Electrical Connection".
Risk of flooding. Close
system shut-off valves before removing
any plugs, caps, or fittings from the
pump. System water pressure will
prevent replacing the fittings once they
are removed.
In normal conditions, electric pumps do
not require any scheduled maintenance.
Periodically check the pressure delivered
and current draw. Reduced pressure
indicates pump wear. Increased current
draw indicates abnormal mechanical
friction in the pump.
Special maintenance may be required
to clean the pump and replace any worn
parts.
At least twice a year, inspect the
expansion tank and check the pre-charge
pressure, the sealing efficiency of the
joints, and all areas for visible signs of
damage and/or corrosion. To check the
pre-charge pressure, close the shut-off
valves on both sides of the pump, turn off
the pump, and drain all water from the
variable speed booster system until the
system water pressure has returned to
zero. On completion of the check, restore
the system to normal conditions.
If the pump is not used for prolonged
periods (e.g. for an entire season) drain
it completely, rinse it with clean water,
and store it in a dry location.
