4. MANAGEMENT
Observe the current accident prevention standards. Risk of crushing. The pump may be heavy. Use suitable lifting methods and always
wear personal protection equipment.
Before handling the product, check its weight to identify suitable lifting equipment.
4.1 Storage
All the pumps must be stored indoors, in a dry, vibration-free and dust-free environment, possibly with constant air humidity. They are supplied
in their original packaging and must remain there until the time of installation. If this is not possible, the intake and delivery aperture must be
accurately closed.
4.2 Handling KVC-KVCX
Avoid subjecting the products to needless jolts or collisions. To lift and transport the unit, use lifting equipment and the pallet supplied standard
(If applicable). Use suitable hemp or synthetic ropes only if the part can be easily slung, connecting them if possible to the eyebolts provided.
In the case of coupled pumps, the eyebolts provided for lifting one part must not be used to lift the pump-motor assembly.
5. WARNINGS
5.1 Checking motor shaft rotation
Before installing the pump you must check that the rotating parts turn freely. For this purpose, remove the fan cover from its seat in the
motor end cover. Insert a screwdriver in the notch on the motor shaft from the ventilation side.

, page 1
Do not force the fan with pliers or other tools to try to free the pump as this could cause deformation or breakage of
the pump.
5.2 New systems
Before running new systems the valves, pipes, tanks and couplings must be cleaned accurately.
To avoid welding waste or other impurities getting into the pump, the use of TRUNCATED CONICAL filters made of corrosion resistant
materials (DIN 4181) is recommended.

6. PROTECTIONS
6.1 Moving parts
Before starting the pump all the moving parts have to be properly protected with dedicated components ( fan, cover, etc.).
During pump operation, keep well away from the moving parts ( shaft, fan, etc.).
If getting closed to the running pump is necessary, be properly dressed as from laws rules, in order to avoid injuries.
6.2 Noise level
See table A, pag. 88.
In cases where the LpA noise levels exceed 85 dB(A), suitable HEARING PROTECTION must be used in the place of installation, as required by
the regulations in force
.
6.3 Hot and cold parts
DANGER OF BURNING !!
As well as being at high temperature and high pressure, the fluid in the system may also be in the form of steam!
It may be dangerous even to touch the pump or parts of the system.
If the hot or cold parts are a source of danger, they must be accurately protected to avoid contact with them.
7. INSTALLATION
The pumps may contain small quantities of residual water from testing. We advise flushing them briefly with clean water
before their final installation.
7.1 Pump installation
−
The electropump must be fitted in a well ventilated place and with an environment temperature not exceeding 40°C.
−
Electropumps with degree of protection IP55 may be installed in dusty and damp environments, without any specific protection.
−
It is always good practice to place the pump as close as possible to the liquid to be pumped.
−
The installation baseplate, provided by the customer, if they are metallic they have to be painted rust and corrosion. They have to be
flat and stiff enough to resist to short circuit forces and avoid resonance due to vibrations.
−
Concrete basements have to be well solid and dry before installing the pumps.
−
A firm anchoring of the feet of the pump assembly on the base helps absorb any vibrations created by pump operation.
−
The pump may be installed in either horizontal or vertical position,
as long as the motor is always above the pump.
−
Ensure that the metal pipes do not transmit excess force to the pump apertures, so as to avoid causing deformations or breakages.
−
Use pipes with a suitable thread to avoid damage to the inserts.
−
The internal diameter of the pipes must never be smaller than that of the apertures of the pump.
