8. Installation, System processing and commissioning
a.
Inspection
Inspect the condensing unit and any accessories shipped with them for damages or
shortages before and during unloading. All items on bill of lading should be accounted
for prior to signing the shipping receipt. Note any shortages or damage on delivery
receipt (specify the extent and type of damage found). Unit should be inspected
carefully for concealed damage. Notify Emerson sales/application personnel of the
damage immediately. Request an immediate joint inspection and do not repair the
unit until inspected by Emerson’s representative.
The system is shipped with a holding charge of dry nitrogen. Check to see that
pressure is still in the unit upon receipt. Report lack of pressure immediately to the
Emerson’s application/sales representative.
b.
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 PMX
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.
Utmost care must be taken while handling the PMX condensing unit.
