INSTALLATION

Choosing a Location

IMPORTANT:

 Consult local and 

national building codes and ordinances for special 

installation requirements� Following location 

information will provide longer life and simplified 

servicing of the outdoor unit�

NOTICE:

 These units must be installed 

outdoors� No ductwork can be attached, or 

other modifications made, to the discharge grille� 

Modifications will affect performance or operation�

Operational Issues

IMPORTANT:

 Locate the unit 

in a manner that will not prevent, impair, or 

compromise the performance of other equipment 

installed in proximity to the unit� Maintain all 

required minimum distances to gas and electric 

meters, dryer vents, and exhaust and inlet 

openings� In the absence of national codes or 

manufacturers’ recommendations, local code 

recommendations and requirements will take 

precedence�
•  Refrigerant piping and wiring should be properly 

sized and kept as short as possible to avoid 

capacity losses and increased operating costs�

•  Locate the unit where water runoff will not create 

a problem with the equipment� Position the unit 

away from the drip edge of the roof whenever 

possible� Units are weatherized, but can be 

affected by the following:

•  Water pouring into the unit from the junction 

of rooflines, without protective guttering� 

Large volumes of water entering the unit while 

in operation can impact fan blade or motor 

life, and coil damage may occur if moisture 

cannot drain from the unit under freezing 

conditions�

•  Closely follow the clearance recommendations 

on page 8�

•  24" [61.0 cm] to the service panel access
•  60" [152.4 cm] above fan discharge (unit top) 

to prevent recirculation

•  6" [15.2 cm] to coil grille air inlets 

with 12" [30.5 cm] minimum recommended

Corrosive Environment

The metal parts of this unit may be subject to 

rust or deterioration if exposed to a corrosive 

environment� This oxidation could shorten the 

equipment’s useful life�
Corrosive elements include, but are not limited to, 

salt spray, fog or mist in seacoast areas, sulphur or 

chlorine from lawn watering systems, and various 

chemical contaminants from industries such as 

paper mills and petroleum refineries�
If the unit is to be installed in an area where 

contaminants are likely to be a problem, special 

attention should be given to the equipment 

location and exposure�
•  Avoid having lawn sprinkler heads spray directly 

on the unit cabinet�

•  In coastal areas, locate the unit on the side of 

the building away from the waterfront�

•  Shielding provided by a fence or shrubs may 

give some protection, but cannot violate 

minimum airflow and service access clearances�

•  Elevating the unit off its slab or base enough to 

allow air circulation will help avoid holding water 

against the base pan�

WARNING:

Disconnect all power 

to unit before starting maintenance� Failure to do 

so can cause electrical shock resulting in severe 

personal injury or death�
Regular maintenance will reduce the buildup of 

contaminants and help to protect the unit’s finish�
•  Frequent washing of the cabinet, fan blade, and 

coil with fresh water will remove most of the salt 

or other contaminants that build up on the unit�

•  Regular cleaning and waxing of the cabinet with 

a good automobile polish will provide some 

protection�

•  A good liquid cleaner may be used several times 

a year to remove matter that will not wash off 

with water�
