NOTES:
1. Air delivery values are based on 230- or 460-volt unit operating voltage without air filter or optional electric heaters Deduct field-supplied air filter and
electric heater pressure drop to obtain external static pressure available for ducting
2 Dashes indicate portions of table that are beyond blower motor capability,
3 Do not operate unit at a cooling airflow less than 350 cfm for each 12,000 Btuh of rated cooling capacity. Indoor coil icing may occur at airflows below
this point
3. Using duct flange as a template, make sure marked
locations line up with clearance holes on flanges.
4. At marked locations, drill screw engagement holes
using a #26 (.147-in.) twist drill.
