WARNING
RISK OF ELECTRICAL SHOCK
!
Before servicing motor-operated equipment, shut off the power at the main electrical panel and disconnect the power supply from motor and accessories.
Use safe working practices during servicing of equipment.
PERFORM INSPECTIONS MONTHLY
1. Ensure pump is still securely bolted to the foundation.
2. To avoid any fire hazards, ensure that there is adequate clearance
from any combustible materials, shelving or cabinets. Ensure
there are no leaves or debris near the pump.
3. Ensure that the motor is securely wired into a proper GFCI-
protected circuit. Test the GFCI periodically by pressing the test
switch when the pump is operating. This should shut off the
pump. If the GFCI does not shut the pump off, have an electrician
replace the GFCI as soon as possible. Remember to reset the GFCI
by pressing the reset switch.
4. Look for any signs of leaks in pipes. Replace or repair, if necessary.
5. Clean the exterior of the pump, if needed, with a solution of
vinegar and water.
DRAINING
Should the unit be subject to freezing, it will be necessary to drain the
pump and tank. To do this, shut off the power to the pump at the main
electrical panel. Open a tap in the water system to release the pressure.
Remove the drain and priming plugs from the pump casing. Remove the
pressure tank drain plug (if so equipped). Allow ample time for the system
to drain before reinstalling the plugs.
LUBRICATION
The pump requires none.
