Product Manual ALR2-3 ALR 110F – 150F 33
Case 2, Two Units Side By Side
Two or more units sited side by side are quite common. If spaced closer than 12 feet (3.7 meters) it is
necessary to adjust the performance of each unit; circuits adjoining each other are affected. NOTE:
This case applies only to two units side by side. See Case 3 for three or more parallel units. Should
one of the two units also have a wall adjoining it, see Case 1. Add the two adjustment factors
together and apply to the unit located between the wall and the other unit.
Mounting units end to end will not necessitate adjusting performance. Depending on the actual
arrangement, sufficient space must be left between the units for access to the control panel (door
opening and/or evaporator tube removal. See “Clearance” section of this guide for requirements for
specific units.
Pit or solid wall surrounds should not be used where the ambient air temperature exceeds 105°F (40°C).
