NOTICE
Avoid handling aluminum coil components after handling the copper line set or other tubing without ¿ rst
cleaning hands.
Unit Sizing
Base the size of the unit on an acceptable heat loss or gain calculation for the structure. Use the ACCA
Manual J or other approved methods. Reference Figure 3 and Table 1
.
1.
Only connect the air handler to a duct system that has an external static pressure within the allowable range.
2.
AirÀ ow must be within the minimum and maximum limits approved for electric heat, indoor coils and out-
door units. Refer to the Dx-Kit section for details.
3.
Install the air handler so that supply ducts carry air circulated by the air handler to areas outside the
space containing the air handler. The return air must also be handled by duct(s) sealed to the air handler
casing and terminating in the space to be cooled/ heated.
4. Refer to the unit rating plate for the air handler model number, and then see the dimensions page of this
instruction for supply air plenum dimensions. You must install the plenum according to the instructions.
5. The installer must check available supply power and verify that it is within the normal operating voltage
range for the unit. The acceptable voltage range for these units is as follows:
