Xylem IM248R01 High Temp Sump Pump User Manual

Page 4

To check the seal housing oil level, where used, lay the

unit on its side with the fill plug at 12 o’clock. Remove

the plug. The oil should be within ½” (13mm) of the top.

If low, refill with an ASTM 150 turbine oil. Replace the

plug.
Oil is available in 5 gallon cans through our distributors.

You can also source oil locally at motor repair shops.

Typical oil brands are: Shell Turbo 32, Sunoco Sunvis

932, Texaco Regal R&O 32, Exxon Nuto 32 and Mobil

DTE Light.
Check the strain relief nut on power cable strain assem-

blies. Power cables should be torqued to 75 in. lbs., cable

supplied is for high temp use.
Warranty does not cover damage caused by connecting

pumps and controls to an incorrect power source (volt-

age/phase supply).
Record the model numbers and serial numbers from the

pumps and control panel on the front of this instruction

manual for future reference. Give it to the owner or affix

it to the control panel when finished with the installation.

FOR ALL SES PUMP INSTALLATIONS

LIFTING OF PUMP

DO NOT LIFT, CARRY OR HANG

PUMP BY THE ELECTRICAL

CABLES. DAMAGE TO THE

ELECTRICAL CABLES CAN CAUSE

SHOCK, BURNS OR DEATH.

Lift the pump with an adequately sized chain or cable at-

tached to the lifting eye bolt. DO NOT damage electrical

cables while raising and lowering unit.

OPTIONAL GUIDE RAIL

OR LIFT-OUT SYSTEM

In many effluent and sewage basins or lift stations it is

advisable to install the pump on a guide rail system or on a

lift-out adapter to facilitate installation and removal for in-

spection and/or service. Most codes do not allow personnel

to enter a wetwell without the correct protective equipment

and training. Guide rails are designed to allow easy removal

of the pump without the need for entry into the wetwell

or need to disturb piping. The guide rail or lift-out adapter

should locate the pump opposite the influent opening pre-

venting stagnate areas where solids can settle. The basin or

pit must be capable of supporting the weight of the pump

and guide rail. The pit floor must be flat.
NOTICE: FOLLOW THE INSTRUCTIONS THAT ARE

PROVIDED WITH THE GUIDE RAIL ASSEMBLY.

PIPING

Discharge piping should be no smaller than the pump

discharge diameter and kept as short as possible, avoid-

ing unnecessary fittings to minimize friction losses. Piping

should be rated for high temperatures if used in high

temperature applications.
Install an adequately sized check valve matched to the

solids handling capability of the pump to prevent fluid

backflow. Backflow can allow the pump to “turbine”

backwards and may cause premature seal and/or bearing

wear. If the pump is turning backwards when it is called

on to start the increased torque may cause damage to the

pump motor and/or motor shaft and some single-phase

pumps may actually run backwards.
Install an adequately sized gate valve AFTER the check

valve for pump, plumbing and check valve maintenance.
Important – Before pump installation. Drill a

⁄

”

(4.8mm) relief hole in the discharge pipe. It should be

located within the wetwell, 2” (51mm) above the pump

discharge but below the check valve. The relief hole al-

lows any air to escape from the casing. Allowing liquid

into the casing will insure that the pump can start when

the liquid level rises. Unless a relief hole is provided, a

bottom intake pump could “air lock” and will not pump

water even though the impeller turns.
All piping must be adequately supported, so as not to

impart any piping strain or loads on the pump.
The pit access cover must be of sufficient size to allow for

inspection, maintenance and crane or hoist service.

WIRING AND GROUNDING

Important notice: Read Safety Instructions before

proceeding with any wiring.

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.
Disconnect and lockout electrical power before

performing any service or installation.
The electrical supply voltage and phase must match

all equipment 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 loca-

tion. The junction box must insure dry,

safe wiring connections.
Seal all controls from gases present which

may damage electrical components.

FAILURE TO PERMANENTLY

GROUND THE PUMP, MOTOR AND

CONTROLS BEFORE CONNECTING
