Location Requirements
To achieve optimum performance and trouble-free
service, it is essential that the proposed installation site
meet with the location and space requirements for the
model being installed.
500 mm
clearance

3500 mm

800 mm
The clearances recommended are nominal for the safe
operation and maintenance of the unit and power and
control panels. Local health and safety regulations, or
practical considerations for service replacement of large
components, may require larger clearances than those
given in this manual.
Units are designed for indoor installation and not
intended for wet, corrosive or explosive atmospheres.
Installation should allow for water drain, ventilation
and suffi cient clearance for service, including tube
cleaning/removal.

INSTALLATION
800 mm
FORM 150.27-NM2.EN.CE (0312)
For installation in equipment rooms near noise-critical
areas, common walls should be of adequate sound
attenuating construction, all doors should be tightly
gasketed, and the unit should have vibration isolators
fi tted.
The concrete base must capable of supporting 150% of
the operating weight. In case of upper fl oors, the unit and
piping should be isolated from walls and ceiling. The
unit may be bolted to the foundation using the 13mm
Ø holes. When lower transmitted vibration levels are
required optional anti-vibration isolators can be supplied
loose for site installation.
Installation of Vibration Isolators
An optional set of spring type vibration isolators can be
supplied loose with each unit.
Pipework Connection
The following piping recommendations are intended
to ensure satisfactory operation of the unit. Failure to
follow these recommendations could cause damage to
the unit, or loss of performance, and may invalidate the
warranty.
The maximum fl ow rate and pressure drop for
the cooler must not be exceeded at any time.
The water must enter the heat exchanger by the inlet
connection.
A flow switch must be installed in the customer
pipework at the outlet of the exchanger as shown in the
arrangement diagrams, and wired back to the control
panel using screened cable. This is to prevent damage
to the exchanger caused by inadequate liquid fl ow.
The liquid pumps installed in the pipework systems
should discharge directly into the unit heat exchanger
sections of the system. The pumps require an auto-starter
(by others) to be wired to the control panel.
Pipework and fi ttings must be separately supported to
prevent any loading on the heat exchanger. Flexible
connections are recommended which will also minimize
transmission of vibrations to the building. Flexible
connections must be used if the unit is mounted on anti-
vibration mounts as some movement of the unit can be
expected in normal operation.
