or power supply. Adhere to local electrical codes
governing pump and control installations.
A control panel is not included with the pump. Install
a simplex or duplex control panel (purchase separately)
for proper pump operation. Single phase pumps require
a start package, as shown in Product Specifications. A
full range of controls and switches are available from
yourdealer.
If a Jung Pumpen control panel is not used, install a
control panel with circuit breaker or fused disconnect
as required by local code. Use magnetic starters with
ambient compensated overload protection. Three phase
units require three line protection; single phase units
require only one line protection. Inadequate protection
voids the warranty.

keep your hands away from the pump inlet opening when
working on or handling the pump for any reason. Do not
use automatic reset controls with this pump.
Single phase units have an automatic overload protector
in the motor which will protect the motor from burning
out due to overheating/overloading. When the motor
cools down, the overload protector will automatically
reset and start the motor. This can happen at any time.
Three phase units require external overload protection.
If the overload trips frequently, check for the cause. It
NOTICE: Normal domestic sewage will cause very little
dulling or wear of the pump parts. However, pumping
abrasives (such as fine sand) will increase wear and
tear and may make it necessary to replace certain
pumpcomponents.
The pump is not equipped with thermostats or a leak
sensor probe. Check the oil condition in the seal
chamber quarterly in heavy duty service or annually in
light duty service.
NOTICE: Failure to monitor the oil condition voids the
warranty. Motors damaged by flooding of the motor
cavity due to seal or O-Ring failure may not be covered
under warranty.
Verify the capacity of the pump by checking the
discharge. Verify that the pump is free from any vibration
and noise.
To avoid overheating the motor for continuous operation,
the pump must be completely submerged in liquid. Set
the level switches to maintain this submerged condition.
Do not allow the pump to run in a dry sump. It will void
the warranty and may damage the pump.
