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 ex-
cluded. National Electrical Codes, local codes and
regulations must be followed.
7.1 Installation
CAUTION! Possible damage of the pump!
Dirt and solder drops in to the pump body can ef-
fect the pump operation.
• It is recommended that any welding and solder-
ing work be done before installing the pump.
• Thoroughly flush the system out before
installing the pump.
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.
- Install the pump in a dry place protected from
frost.
- The installation surface must be level and flat:
any tilting of the pump would cause premature
bearing wear. Horizontal deviation allowed ± 5°
maximum.
- Install the pump on a concrete block (at least ¾"
/ 20mm high) Install an insulating material under
the concrete block (cork or reinforced rubber) to
avoid any noise and Vibration transmission into
the installation.
- The installation and connection dimensions are
given §5.2
- The flow direction of the fluid is indicated on the
identification label of the pump.
- Pump must be installed in such a way that it is
not stressed by the pipework. The pipes must be
attached so that the pump does not bear their
weight.
- It is recommended that isolation valves be in-
stalled on the suction and discharge side of the
pump. This will save having to drain and refill the
system if the pump needs replacing. The valves
are to be installed so that any water that escapes
cannot drip onto the pump motor or terminal
box.
- Suction pipe diameter should not be less than the
pipe size of the pump itself.
