8. PREPARING FOR USE
WARNING!
Installation must be performed by qualified or
factory trained personnel.
When lifting the pump/motor, use appropriate lift
equipment, and check position and tightness of
lift system so that the weight of the pump remains
balanced. Failure to observe this precaution may
result in serious accidents.
Lifting eye(s) attached to the motor (if provided)
are intended only for lifting the motor and must
not be used to lift the complete pump assembly.
8.1 COUPLING TO THE MOTOR
The motors to be coupled to the EVMU and EVMSU pumps must
meet NEMA standards. Consult motor nameplate and motor
manufacturer's specifications for additional guidance on motor
installation and operation, including maximum starts per hour.
Check that all power is off and that the motor is disconnected
from the power supply prior to ANY work performed on the
pump and/or motor.
It is strongly suggested to perform a start-up test run following cou-
pling to check operation. If possible, it is suggested to perform cou-
pling once the pump has been fastened down in its working
position and connected to the suction and discharge pipes.
8.1.1 ASSEMBLING THE MOTOR TO THE PUMP
WARNING!
The following procedure must be done with the
unit disconnected from its electrical power supply.
EVMSU1 to EVMSU20 [- A -] and EVMU32-1
1. Position and secure the pump vertically on a flat, rigid surface.
2. Unscrew the 4 coupling guard screws, then remove the two
coupling guards. [A-1]
3. Remove foam packing material from around the coupling. [A-1]
4. EVMSU only: Evenly loosen the three set screws in the
seal holder (shaft locking collar) by one full turn. [A-2]
5. Unscrew the coupling screws and remove both coupling halves
from the pump. [A-3]
6. EVMSU only: Remove the motor key from the motor and
install the half-key. [A-4]
The half-key should not protrude from the slot in

the motor shaft.
7. Set the motor vertically with its shaft downwards and place
it over the pump. [A-5]
8. Insert and evenly tighten down the 4 motor bolts to the
torque specified on page 14. [A-5]
9. Loosely reinstall the coupling halves. For EVMSU, the half-key
must face away from the gap between the coupling
halves. [A-6]
10. Use a suitable lever to pry the coupling upward until it stops
against the end of the motor shaft. [A-7]
11. With the coupling raised, evenly tighten the four coupling bolts
evenly to the torque specified on page 14. [A-7]
12. Rotate the coupling by hand and use a feeler gauge to
check that the gap between the coupling halves is even. If
not, repeat from step 9. [A-8]
13. EVMSU only: Evenly tighten the three set screws on the
seal holder to the torque specified on page 15. [A-9]
WARNING!
The seal holder set screws must be tightened prior
to operation or damage to the pump may occur.
14. Reinstall the two poupling guards. [A-10]
15. The motor is now installed.

8.2 GENERAL INSTALLATION PRECAUTIONS
WARNING!
a) Use metal or rigid plastic pipes to avoid pipe strain or collapse
b) Support and align pipes so that they do not put any stress
c) avoid throttling caused by bending suction and discharge hoses;
d) seal any piping connections: air infiltration in the suction
e) isolation valves should be installed on both the suction and
WARNING!
f) properly support and secure all piping so tha tit is not
g) use minimal bends (goosenecks) and valves;
h) in suction lift installations, the suction pipe should be fitted
i)
j)
Standard ANSI mating flanges should be used to connect the
pump to the piping. Suction and discharge piping should be no
smaller than the respective pump port sizes.
8.2.1 INSTALLATION
a) Position the pump on a flat surface that is as close as
b) use standard plumbing practices to avoid unnecessary line
8.2.2 POSITIONING THE PRODUCT
WARNING!
Note: The ambient temperature and altitude ranges are provided
in Section 10.1.
Place the pump away from walls, the ceiling or other obstacles so
that the pump can be fastened, operated and serviced safely.

Remove the suction and discharge caps before
connecting the pump to the piping.

on the pump;
pipe negatively affects pump operation;
discharge side of the pump in the event service of the
pump is required; it is recommended that a bleed valve be
installed in the discharge line to allow pressure in the pump

Installing a bleed valve is especially necessary in
hot water applications to prevent injury.
supported by the pump;
with a foot valve and filter in order to prevent foreign matter
from entering, and its end should be immersed at a depth
that is at least twice the diameter of the pipe; its distance
from the bottom of the reservoir should also be one and a
half times its diameter.
For suction piping exceeding 13 feet use an oversized pipe
(1/4" wider at suction) for improved efficiency;
ensure that the pump suction, marked by a sticker, is connected
to the liquid source and that the discharge, similarly marked,
is connected to the discharge line;
ensure that the suction and discharge gaskets are properly
installed to prevent leaks and that they do not restrict the
flow to or from the pump.

ventilation around the pump to allow safe use and mainte-

"free space" in front of the cooling fan;

Install the pump in a ventilated area protected
from weather or destructive elemdnts
