TYPICAL INSTALLATION
APPLICATION DATA
1. Condensate trap — A 2-in. condensate trap must be field
supplied.
2. Ductwork — Secure downflow discharge ductwork to roof
curb. For horizontal discharge applications, attach ductwork
to unit with flanges.
Units are equipped with factory-installed duct covers on both
the downflow and horizontal openings. Remove appropriate
duct panel covers for intended discharge application. Units
utilizing downflow option do not require duct panel cover
removal.
3. Thermostat — To achieve simultaneous economizer cooling
and mechanical cooling, use of 2-stage cooling thermostat
is recommended for all units equipped with accessory
economizer.
4. Airflow — Units are draw-thru on cooling and blow-thru on
heating.
5. Maximum cooling airflow — To minimize the possibility of
condensate blow-off from evaporator, airflow through units
should not exceed 450 cfm/ton.
Minimum cooling airflow is 350 cfm/ton.
Minimum ambient operating temperature for standard units
is 40 F. With accessory low ambient temperature kit, units
can operate at temperatures down to 0° F.
