Installation Guidelines 

 

Location Considerations 

The chiller must be installed with enough clearance for service and for unrestricted air intake and exhaust. The 
chiller must be located sufficiently close to the process to ensure adequate flow rate of coolant by not exceeding 
the capabilities of the chil

ler’s pumps. The following sections outline recommended installation practices. 

The 

chiller has potential for misuse that could result in unplanned downtime. The main disconnect, drain, and field 
installed service valves can be operated by unauthorized personnel. If unauthorized operation is a concern, then 
a security fence should be provided to reduce the potential for misuse. Fencing must not obstruct airflow and 
must leave room or be removable for service

. The chiller’s air intake and exhaust clearances must adhere to the 

following: 

Table 4: Chiller Air Intake and Exhaust Requirements 

Criterion 

Value 

Vertical clearance 

≥ 8ft (2.4m)

 

Horizontal clearance (Door, Enclosure, and Rear Sides) 

≥ 3ft (.9m)

 

Horizontal clearance (Air intake side) 

≥ 6ft (1.8m)

 

Exhaust air must be freely discharged by the chiller’s fans. This air must not be recirculated to the air intake side 

of the chiller. Avoid installing deflectors that redirect air to the air intake side of the chiller or installing ducting 

that directly connects to the chiller’s top. The chiller uses axial fans that are not compatible with exhausting air 

through ducting. Ducting increases the pressure drop of the fans severely and lowers the volumetric air flow. 

 

NOTICE 

Improper air intake and exhaust clearances can lead to reduced capacity, thermal 
overloading of the fan motors and/or compressors, high pressure refrigeration 
faults, and/or rendering the chiller inoperable. 

If ducting must be installed at the chiller’s location a suitable duct auxiliary fan 

must be provided. Consult the factory for guidelines and recommendations. 

 
Make sure the unit is placed, on a level, hard surface. The chiller must be level or less than ½ inch of slope per 10 
feet. Use shims to correct level if needed. If the chiller is mounted on a concrete slab, the slab should be 4-inch 
thick and at least 5 feet x 12 feet. If the chiller is roof mounted, two I-beam runners are typically provided to 
support the chiller feet at both ends. For rooftop mounting, chiller should be anchored through the mounting 
holes provided in the feet. When the chiller is mounted above an office space, optional vibration mounting 
springs can be used to isolate the chiller from the building structure.
