Installation and Application Information

Operational Spacing Requirements

Sufficient clearance must be maintained between the unit

and adjacent walls or other units to allow the required unit air

flow to reach the coils. Failure to do so will result in a capacity

reduction and an increase in power consumption. No solid

obstructions are allowed above the unit at any height, see

page

for details.

The clearance requirements shown are a general guideline

and cannot account for all scenarios. Such factors as prevailing

winds, additional equipment within the space, design outdoor

air temperature, and numerous other factors may require more

clearance than what is shown. Additional clearances may be

required under certain circumstances.
Graphs on the following pages give the minimum clearance for

different types of installations and also capacity reduction and

power increase if closer spacing is used. The graphs are based

on individual cases and should not be combined with other

scenarios.

CAUTION

Unit performance may be impacted if the operational

clearance is not sufficient.

Case 1: Building or Wall on One Side of Unit

NOTE:

Assumes a solid height wall taller than unit. Refer to

Case 4 for partial wall openings.

For models AGZ030-101E, maintain a 4 feet minimum from a

wall of any height.
For models AGZ110-130E, maintain a 6 feet minimum from a

wall of any height.
For models AGZ140-241E, maintain a 8 feet minimum from a

wall of any height.

Figure 4: Building or Wall on One Side of Unit

Case 2: Two Units, Side-by-Side

For models 030-180, there must be a minimum of 4 feet

between two units placed side-by-side; however, performance

may be affected at this distance. For models 191-241,

the minimum is 6 feet as closing spacing may cause air

recirculation and elevated condenser pressure. Assuming

the requirement of one side having at least 8 feet of

service clearance is met, Case 2 figures show performance

adjustments as the distance between two units increases.
