11. Installation, System Processing and Commissioning
Utmost care must be taken while handling the Large ZX condensing unit.
Please go through the contents below to ensure proper handling.
a. Location and Fixing
Large ZX should always be installed in a location that ensures clean air flow. The minimum operat-
ing space for unit is described in below figure. Both service access and airflow have been consid-
ered 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 varia-
tions 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 Large 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.
