9.  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 careful-
ly 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. Installation Base

 The unit should always be installed in a location that ensures clean air flow. Both  

 

service access and airflow have been considered in making these recommenda  

 tions.

Where multiple units are installed, due care should be taken to avoid the discharge  

 

air from each unit adversely affecting other units in the vicinity.  

Ideally, the unit should be mounted on a solid concrete slab with anti-vibration  

 

pads between unit feet and concrete. 

Ensure that there is no obstruction to air flow into or out of the unit. Remove obsta 

 

cles which block air intake or discharge 

The location must be well ventilated, so the air can pass properly through condens 

 

er by maintaining the proper condensation in the system.  

To optimize the unit running conditions, the condenser coil must be cleaned at  

 

regular intervals

c. 

Installation Clearance

It is recommended to have a minimum clearance of 800 mm between the condenser 
face and adjacent wall, while a minimum clearance of 1600 mm between two adjacent 
units for service and sufficient air circulation.
