Operation And Installation - Master Plumber 539892 Manual Del Usuario

Electrical / Operation / Service
Use a 2" (5.1 cm) swing check valve in pump discharge to
prevent backflow of liquid into sump basin. Check valve
should be a free flow valve that will easily pass solids.
NOTICE: For best performance of check valve when han-
dling solids, do not install it with discharge angled more
than 45° above the horizontal. Do not install check valve
in a vertical position as solids may settle in valve and pre-
vent opening on startup.
Drill a 3/16" (4.7mm) hole in discharge pipe about 1"-2"
(2.5 - 5.1cm) above pump discharge connection (but
below check valve) to prevent airlocking the pump.
ELECTRICAL
Hazardous voltage. Can shock, burn, or
cause death. When installing, operating, or
servicing this pump, follow safety instructions listed
below.
1. DO NOT splice the electrical power cord.
2. DO NOT allow electrical cord plug to be submerged.
3. DO NOT use extension cords. They are a fire hazard
and can reduce voltage sufficiently to prevent pump-
ing and/or damage motor.
4. DO NOT handle or service pump while it is connected to
power supply.
5. DO NOT remove grounding prong from plug or modify
plug.To protect against electrical shock, the power
cord is a three-wire conductor and includes a 3-prong
grounded plug. Plug pump into a 3-wire, grounded,
grounding-type receptacle. Connect pump according
to electrical codes that apply.
For automatic operation, plug or wire pump into an auto-
matic float switch or pump controller. Pump will run con-
tinuously when plugged directly into an electrical outlet.
Connect or wire pump to an individual branch circuit with
no other outlets or equipment in the circuit. Size fuses or
circuit breakers according to Fuse Size Chart at right.
Risk of electrical shock and fire. Be sure
that power supply information (Voltage/
Hertz/Phase) on pump motor nameplate matches
incoming power supply exactly. Install pump according
to all electrical codes that apply.

OPERATION AND INSTALLATION

NOTICE: Do not allow pump to run in a dry sump. It will
void the warranty and may damage the pump.
An automatic overload protector in the motor will protect
motor from burning out due to overheating/overloading.
When motor cools down, overload protector will auto-
matically reset and start motor.
If overload trips frequently, check for cause. It could be a
stuck impeller, wrong/low voltage, or electrical failure in
motor. If an electrical failure in the motor is suspected,
have it serviced by a competent repairman.
Pump is permanently lubricated. No oiling or greasing is
required.
GENERAL
Hazardous voltage. Can shock, burn, or
cause death. Before removing pump from
basin for service, always disconnect electrical power to
pump and control switch.
Risk of electrical shock. Can burn or kill.
Do not lift pump by ower cord. See "Cord
Lift Warning" on Page 5.
Submerge pump in a disinfectant solution (chlorox or
chlorine) for at least one hour before disassembling
pump.
The pump motor contains a special lubricating oil which
should be kept clean and free of water at all times.
