OUTDOOR UNIT INSTALLATION

• The installer shall check available power to make certain it

matches the unit (Name Plate Rating) and that constant voltage
can be maintained to the unit. Unsatisfactory performance
would otherwise result. The local power company should be
contacted regarding problems or questions concerning power
supply.

• Install a line service disconnect switch within sight of the

condensing unit. The line voltage service wiring for the
condensing unit should include a fused disconnect switch.

• Use correct wire size and fuse size. To ensure that adequate

voltage will be available at the condensing unit, the line voltage
service wiring must be of adequate size. Minimum
recommended wire ampacities and maximum fuse sizes are
listed on the unit name plate.

• Two holes are provided in the control box

a.

One is for the connection of the line voltage conduit 
or cable. The hole is sized for 3/4" conduit.

b. 

One is for low-voltage wiring. Refer to the wiring 
diagram attached to electrical box cover for connection.

• Be sure to ground the condensing unit by securing the ground

wire to the grounding lug inside the control box

• Be sure to follow National Electrical Code and all local codes

Electrical equipment should be installed by a qualified, licensed
electrician. Improper electrical hook-up may damage
equipment, can create a hazard, cause personal injury or death,
and will void the warranty.
