CLEARANCES

NOTE : NUMBERS IN () = mm
IMPORTANT : When installing multiple units in an alcove, roof well or partially enclosed area, ensure there is adequate ventillation to prevent re- circulation of discharge air.

Control Wiring

Application Guidelines

Intended for outdoor installation with free air inlet and outlet. Outdoor fan external static pressure available is less than 0.01 -in. wc.
Minimum outdoor operation air temperature for cooling mode without low-ambient operation accessory is 55°F (12.8°C).
Maximum outdoor operating air temperature is 125°F (51.7°C).
For reliable operation, unit should be level in all horizontal planes.
Use only copper wire for electric connections at unit. Aluminum and clad aluminum are not acceptable for the type of connector provided.
Do not apply capillary tube indoor coils to these units.
Factory-supplied filter drier must be installed.

3/4” suction line should only be used for 2 ton systems if the outdoor unit is below or at the same level as the indoor unit to ensure proper oil return.
Always use the smallest liquid line allowable to minimize refrigerant charge.
Applications shaded in light gray indicate capacity multipliers between 0.90 and 0.96 which are not recommended but are allowed.
Applications shaded in dark gray are not recommended due to excessive liquid or suction pressure drop.
