3.2 PUMP MEDIUM
Pump medium can be pure water or a mixture of pure water and glycol, which is appropriate for heating or chilled
system. The medium must be free from aggressive or corrosive additives, free from mixtures of mineral oils and solid or
fibrous particles. The pump should not be used for pumping flammable, corrosive media and in an corrosive atmosphere.
Permanent magnet rotor inside the pump is prone to accumulating magnetic particles on its surface, which can lead to
abrasion of bearings and rotor can or even blocking the rotor. Although the pump is built in a way that the effect of
magnetic particles is minimal, failures of bearings, rotor cans and blocked rotors are not covered by the warranty. To
ensure the pump is operating in optimal condition and eliminate any presence of magnetite in the system we
recommend the use of magnetite filter.
3.3 TEMPERATURES AND AMBIENT HUMIDITY
Permitted ambient and media temperature:
Ambient temperature
[°C]
Medium temperature [°C] Relative ambient humidity

4PUMPINSTALLATION
4.1 MECHANICAL INSTALLATION INTO SYSTEM PIPEWORK
The pump is packed in a double cardboard box to ensure protection during transport and handling in the plantroom.
Once the box is open, use the plastic handles to lift the pump out of the box or lift it holding the drive heat sink.
Pumps are designed to be mounted on the pipework with connecting flanges using screws in each flanges holes to ensure
water tightness between the pump and the mating pipwork. The pump flanges are designed so the pump can be installed
in PN6 or PN10 nominal pressure pipelines up to DN65. Because of the combined flange design, washers must be used
on the pump side, when installing the pump.
For the pump to operate with minimal vibrations and noise, it should be installed into the pipework with its axis (or shaft)
in horizontal position, as showed in figure 1.
The small rectangular openings at the base of the motor (showed on Fig.1, point A) are designed to prevent any
condenation forming inside the motor. These should be left open and not covered (for examples, pump clading should
not covers them).
Fig.1
Desired controls orientation can be achieved by rotating the pump head (pump positions shown in figure 3). Pump
head is mounted to hydraulic casting with four screws. By unscrewing those, the pump head can then be turned (Fig.2).
Fig.2
1. Unscrew the
pump head from
the pump casing
2. Gently pull the
head out a little. This is
to avoid damaging the
pump body gasket.
3. Rotate the head to
the desired orientation.
Note that the Electrical
connection should not be
facing up.

11
4.2 HYDRAULIC INSTALLATION INTO SYSTEM
The pump is designed to be installed into the pipework only in certain orientation, this is to avoid any air to be trapped
inside the pump and risk of damaging the bearings or overheating the pump.
Fig.3
To ensure the pump delivers the required flow and pressure, the pipework designer should also consider a minimum
length of pipwework to be straight (without bends) for 5-10 D (D = rated pipe diameter) from the flanges on the inlet
and the outlet side of the pump.
Ambient environment around the pump should be dry and illuminated as appropriate and the pump should not be in
direct contact with any objects. Pump seals prevents dust and particles from entering in the pump as per the IP class
rating. Make sure that the distribution box cover is mounted properly and that the cable glands are tightened and are
sealing.
The Pump will provide the longest lifetime with ambient temperature within the limits specified and moderate medium
temperature. Prolonged operation at elevated temperatures could increase wear. In general, aging of any rotating
machine is accelerated by high power and high temperatures.

12
xMisconnection or overload could cause pump shutdown or even permanent damage.
xPumps might be heavy. Ask for some assistance and help if needed,
xPumps must not be used in the safety pipelines,
xPumps should not be used as a holder during welding!
xWhen reassembling, care should be taken to ensure seal fit. Failing that, water could
cause damage to pumps internal parts,
xDrains between pump motor housing and hydraulic housing must be left free (should
not be thermally insulated), as it could interfere with cooling and condensate drainage
xHot medium can cause burns! The motor can also reach temperatures that could cause
injury.
xMotor housing should not be termally insulated
4.3 ELECTRICAL INSTALLATION
Electrical connection is done with connector supplied with the pump (pumps with power < 200W) or with a built in
connector for pumps with power rating above 200W (figure 4).
Fig.4
The pump has a built-in overcurrent fuse and protection, temperature protection and basic overvoltage protection. It
doesn’t need an additional thermal protection switch. The electrical power cables used should be capable of carrying
rated electrical current and should be properly fused. Ground lead connection is essential for safety. It should be
connected first. Grounding is only meant for pump safety. Pipes should be grounded separately.
