Installation
condensation coils must be protected from side winds when their speed exceeds 16 km/h. Position the unit above the average height of snow observed in the region where it is installed. Never install temporary or permanent objects (tarp or roof) over the unit, because recycling of hot air would reduce the capacity of the condensation coils. Discharged air from the fans must not be obstructed. It is prohibited to install ducts for the fan discharge air (even short ones).This is because the fans supplied on standard units do not generate any additional static pressure.
dimensions and recommended clearances. Unobstructed flow of condenser air is essential to maintain chiller capacity and operating efficiency.
Note for RTCA: When determining unit placement, give careful consideration to ensuring a sufficient flow of air across the condenser
Clearances
