5.6.3 Positioning
The condenser must be installed on a level surface that can support the weight of the
equipment and allowing for access from all sides. If multiple condensers are used for
1 indoor unit,
the condensers must be installed on the same level and the same
distance to the indoor unit .
Whenever possible, shelter condensers from winds and avoid prevailing winds blowing
directly onto the fan(s) or the heat exchanger. Always bolt down units to ensure secure
fixing to location.
Consideration should also be given to minimising the noise created by the condenser.
Pipework and cabling running underneath the unit should be configured so as not to
obstruct airflow.
Pipework and cabling underneath the unit can cause a reduction in airflow as well as
an increase in noise as air passes around the obstruction.
All outdoor units should be fixed to a rigid structure using the holes provided (wherever
possible). If the units are in an exposed situation and normal bolting is not practical,
then alternative brackets, fixings or adhesive should be used.
Condensers are delivered with the mounting legs loose, allowing for installation on site
to decide the orientation of the unit (vertical or horizontal). The legs have been desi-
gned to maximise the clearances onto the coil, so it is essential they are installed cor-
rectly.
The hot gas discharge line MUST be positioned at the top of the condenser for hori-
zontal airflow (labelled as 1 on the diagrams below). Therefore, the liquid line (labelled
as 2) will be at the bottom of the unit.
Vertical airflow condensers must not be installed upside down.
