It contains every necessary information for installation,
correct use and maintenance of CMV pumps.
- It's very important that the user reads this manual
before using the pump. Any damage caused by failure
to observe the directions contained in this manual will
not be covered by warranty.
- By the time you receive this pump check
if it wasn´t damaged during transpor-
tation.
- In this case, please contact our agent as soon as
possible.
2. OPERATING CONDITIONS:
- The CMV are centrifugal multistage pumps and have
been designed to work with clean water at a maximum
temperature of 35º C.
- Maximum starts/hour: 30 at regular intervals.
3. INSTALLATION:
- The pump should be fixed to a solid base by bolts
through the holes in the bottom of the pump in order
to prevent unwanted noise or vibration.
- You should place pump as near as
possible to water level so to have the
minimum suction lift and reduce loss of
head.
- Make sure that pump is never submerged and that it
rests in a dry and well aired room.
4. PIPES ASSEMBLY:
- Suction pipe (Pic. 1) must be the same or lower
diameter than the pump inlet and must always remain
in na upward inclination of 2% so to help with correct
priming.
- A foot valve with filter should be installed and
submerged to at least 30cm below the well dynamic
level to prevent air from entering the pump.
- Be sure that discharge pipe (Pic. 1) should never rest
on top of the pump.
5. ELECTRICAL CONNECTION:
- The single-phase motors have a built-in thermal
protection.
- The electrical installation must have a system of
multiple separations with contact opening of at least 3
mm.
- The protection of the system will be based on a
differential swith ( I fn = 30 ma).
- The electric cable must correspond to the EEC (2)
norm or to the type H07 RN-F.
- With three-phase motors, end-user must install
himself the correct protection to the pump as per the
aproppiate installation regulations.
- Follow directions on Pic.3. for a correct electrical
connection.
6. CONTROLS PRIOR TO THE INITIAL
STARTING:
- Check that voltage and frequency correspond to
those indicated on the technical characteristics label.
- Make sure the motor shaft is turning freely.
- Fill pump body completely with water, as well as the
suction pipe, through the priming hole (Pic. 4). Check
that there is no leaking through joints or connections.
