Installation and Operations Manual
Unit Access
Always provide sufficient clearance for unit maintenance and service. Minimum clearances for most situations are described below (except 60 Inches of free space is required in front of the control panel). Please note that these are minimums and more clearance may be required by local codes.
Vertical Clearance
Overhead obstructions are not permitted. Vertical air discharge from the condenser must have no obstructions that can cause the discharge air to be recirculated back to the inlet side of the unit.
Lateral Clearance (Walls or Obstructions)
The unit should be located so that air may circulate freely and not be recirculated. For proper air flow and access, all sides of the unit (except control panel end ) should be a minimum of four feet (1.2 m) away from any wall or obstruction. It is preferred that this distance be increased whenever possible. Care should be taken to see that ample room is left for maintenance work through access doors and panels. When the unit is in an area where it is enclosed by three walls the unit must be installed under the guidelines for unit installations in pits.
Decorative Fences
Fences may be installed closer than the four foot (1.2 m) lateral minimum (except on the control panel end) requirement whenever fences permit sufficient free area to allow adequate air flow to the unit. Once again, care should be taken to leave ample room for unit service. Recommended service clearances are listed above.
Units in Pits
The top of the unit should be level with the top of the pit. If the top of the unit is not level with the top of the pit, a wider pit or discharge stacks must be used to raise discharge air to the top of the pit. This is a minimum requirement.
Multiple Units
For units placed side by side, the minimum distance between units is eight feet (2.4 m) to prevent air recirculation.
