Assembly And Disassembly; Preparation For Use - EBARA JEU Operating Instructions, Installation & Maintenance Manual

Ebara Self Priming Jet Pumps
Installation
Temporary Installation (For Temporary Use)
a)The pump must be placed on a level surface, as near as possible to a
source of water.
b)When positioning the pump, observe the minimum required distances from
walls, so as to allow functioning, use and maintenance operations in
safe conditions.
c) Use pipes with a suitable diameter (see page 4) fitted with threaded
couplings, and screw them onto the suction and discharge areas of the
pump.

assembly and Disassembly

The pump has no separate accessories, so no assembly is required for installation.
If the pump has to he disassembled (due to breakage or any other reason), the
user must notify their distributor or Ebara International Corporation.
FAILURE TO COMPLY WITH THIS RENDERS THE WARRANTY VOID.

Preparation for Use

On three phase JEU pumps, check the direction of rotation of the motor. The
impeller must turn in a clockwise direction when viewing the pump from above
(see the arrow on the pump). as it is not possible to check the direction of rotation
of the impeller visually, proceed as follows: before anchoring the pump in the
system and without the pipes, connect the power cables to the electric panel
and switch on the main switch for a moment; the direction of rotation of the fan
that cools the motor of the pump is the same as the direction of rotation of the
impeller. If it is turning in the wrong direction (that is counterclockwise), invert
two of the three leads on the motor base.
Electrical Connection
AVOID GETTING THE BASE WET OR DAMP WHEN CONNECTING THE PUMP.
THE ELECTRICAL CONNECTION MUST BE CARRIED OUT BY A TRAINED
ELECTRICIAN.
FOR BOTH THE THREE-PHASE AND THE SINGLE-PHASE VERSION,
EBARA RECOMMENDS FITTING A HIGH-INTENSITY DIFFERENTIAL
PRESSURE SWITCH IN THE ELECTRIC SYSTEM (0.03A).
