PUMP PROTECTION
We recommend using SymCom's PumpSaver to protect the system from low
water, rapid cycling, high/low voltage, dead heading/flow restriction and
overcurrent.

Do not lift, carry or hang pump by the electrical cables.
Damage to the electrical cables can cause shock,
burns or death.
Use only stranded copper wire to pump/motor and ground.
The ground wire must be at least as large as the power supply
wires. Wires should be color coded for ease of maintenance
and troubleshooting.
Install wire and ground according to the National Electrical
Code (NEC), or the Canadian Electrical Code, as well as all
local, state and provincial codes.
Install an all leg disconnect switch where required
by code.
The electrical supply voltage and phase must match all equip-
ment requirements. Incorrect voltage or phase can cause fire,
motor and control damage, and voids the warranty.
All splices must be waterproof. If using splice kits follow
manufacturer's instructions.
Select the correct type and NEMA grade junction box for the
application and location. The junction box must insure dry,
safe wiring connections.
All motors require a minimum 5' submergence for proper refill
check valve operation.
Failure to permanently ground the pump, motor and controls
before connecting to power can cause shock, burns or death.
All three phase (3Ø) controls for submersible pumps must
provide Class 10, quick-trip, overload protection.
4" motors ≥ 2 HP require a minimum flow rate of .25 ft/sec.
or 7.62 cm/sec. past the motor for proper motor cooling.
The following are the minimum flows in GPM per well
diameter required for cooling: 1.2 GPM/4", 7 GPM/5",
13 GPM/6", 20 GPM/7", 30 GPM/8" or 50 GPM in a 10"
well.
Pumps ≥ 2 HP installed in large tanks should be installed in a
flow inducer sleeve to create the needed cooling flow or veloc-
ity past the motor.
This pump has been evaluated for use with Water Only.
