General Information

Electric Service – All wiring should be done in accor-
dance with local and national electrical codes. Electric
service for the replacement unit is via a receptacle type
outlet furnished with 265V units. 208/230V units are
equipped with a plug and cord set to plug into a recep-
tacle which is supplied by others and field installed.
The use of an extension cord to increase the length
of the plug/cord set furnished as a part of the unit is not
recommended.
Suggested Outlet Locations
1. Floor Mounted Conditioners – 208/230V units
only. Mount an outlet in the wall to the right or left
of the conditioner (see Figure 4). The chassis' cord
has a 72 inch usable length from where it exits from
the lower right of the front panel.

2. Wall Mounted Conditioner – 208/230V units
only. A receptacle is generally mounted beneath
the conditioner on, or recessed in, the wall so it is
concealed by the conditioner overhang (see Figure
5). The chassis' cord has a 18 inch usable length
from where it exits from the lower right of the front
panel.

3. Conditioner with Subbase – Required with 265V
units, optional with 208/230V units. The subbase
includes an electrical compartment in the right front
corner providing brackets for mounting a receptacle
directly beneath the base pan knockout. There is no
need for a junction box when this method is used
(see Figure 6). Since 265V units require a subbase,
the electrical cord is only long enough to reach a
receptacle in the subbase.
In all cases, excess cord should be rolled up an stored
in the conditioner.
