6.2 Design of product
• Helix pumps are vertical high pressure non-self
priming pumps with inline connection based on
multistage design.
• Helix pumps combine use of both high efficiency
hydraulics and motors (if any).
• All metallic parts in contact with water are made
of stainless steel.
• For models equipped with heaviest motor (>40
kgs), a specific coupling allows to change the
seal without removing the motor. A cartridge
seal is then used in order to ease maintenance.
• Special handling devices are integrated in order
to facilitate pump installation.
7. Installation and electrical connection
Installation and electrical work in compliance
with any local codes and by qualified personnel
only.
WARNING! Bodily injury!
Existing regulations for the prevention of acci-
dents must be observed.
WARNING! Electrical shock hazard!
Dangers caused by electrical energy must be
excluded.
7.1 Commissioning
Unpack the pump and dispose of the packaging
in an environmentally-responsible manner.
7.2 Installation
The pump must be installed in a dry, well-venti-
lated and frost-free place.
CAUTION! Possible damage of the pump!
Dirt and solder drops in to the pump body can
effect the pump operation.
• It is recommended that any welding and sol-
dering work be done before installing the pump.
• Thoroughly flush the system out before
installing the pump.
- The pump must be installed in an easily accessible
position to facilitate inspection or replacement.
- For heavy pumps, install a lifting hook (Fig. 2,
item 10) above the pump in order to ease its dis-
assembly.
- The motor is provided with condensate hole
(under the motor), filled in factory by caps to
guarantee the IP55 protection. For a use in tech-
nical climatological or refrigerated, these caps
must be removed to allow the evacuation of the
water of condensation.
WARNING! Risk of accident by hot surfaces!
The pump must be positioned so that someone
cannot come into contact with the hot pump sur-
faces while operation.
