ZX Platform Condensing Unit
8
Installation
Copeland ZX condensing units are delivered with a holding charge of neutral gas. The condensing unit should be located in such a place
to prevent any dirt, plastic bag, leaves or papers from covering the condenser and its fins. The unit must be installed without restricting
the airflow. A clogged condenser will increase the condensing temperature, thus reduce the cooling capacity, and lead to a high-
pressure switch tripping. Clean the condenser fins on a regular basis.
Installation / Piping Instructions
It is recommended that a clearance of 8 inches from the wall (or the next unit) be maintained from the unit’s left and rear panel whereas
a clearance of 20 inches is to be maintained from the unit’s right, top and front panels. Both service access and airfl ow have been
considered in making these recommendations. Where multiple units are to be installed in the same location, careful consideration for
proper clearance needs to be given to each individual unit.
Ideally, the unit should be mounted level on a solid concrete slab with rubber strips between unit feet and concrete. However, these units
have been designed for mounting on suitable brackets for wall mounting. In this case it is equally important that the spatial guidelines
given above are followed, and additional consideration needs to be given for possible air recycling if units are stacked above and below
each other. In general terms, air by-pass around each condenser and between each unit should be avoided at all times.
Pipe sizing should not only be of sufficient size to ensure optimum performance and good oil return, but it also needs to take into
account the full capacity range through which this particular unit will need to operate. Follow the ASHRAE guidelines for proper
piping practices.
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.
