Location and fixing
The unit should always be installed in a location that ensures clean air flow. It is recommended that a clearance of 300 mm
from the wall (or the next unit) be maintained from the unit’s left and rear panels whereas a clearance of 500 mm must be
maintained from the unit’s right, top and front panels (seen facing the front of the unit). Both service access and airflow
have been considered in making these recommendations. Where multiple units are to be installed in the same location, the
contractor needs to consider each individual case carefully. There can be many variations of unit quantities and available space
and it is not the intention of this manual to go over these. Ideally, the unit should be mounted on a solid concrete slab with
anti-vibration pads between unit feet and concrete. However the ZX condensing unit has also been designed for wall mounting
on suitable brackets. Wall mounting brackets are not included. Another factor to consider in finding a good installation site is
the direction of the prevailing wind. For example if the air leaving the condenser faces the prevailing wind, the air flow through
the condenser can be impeded, causing high condensing temperatures ultimately resulting in reducing unit life. A baffle is a
remedy for this situation.
