SAFETY CONSIDERATIONS
Installing, startingup,and servicing air-conditioning equipment can be hazardous due to system pressures, electrical
components, and equipment location.
Only trained, qualified installers and service mechanics
should install, start-up, and service this 09BY equipment
(Fig. 1).
When working on the equipment, observe precautions in
the literature and on tags, stickers, and labels attached to the
equipment.
Follow all safety codes. Wear safety glassesand workgloves.
Keep quenching cloth and fire extinguisher nearby when brazing. Use care in handling, rigging, and setting bulky
equipment.
ELECTRIC SHOCK HAZARD
Separate power sources (main and control
power circuits) are used for these units. Be
sure both main and control power circuits are
disconnected before servicing.
GENERAL
The 09BY air-cooledcondenser is a remote air-cooled condenser designed to be used with the 50BZ vertical packaged
units. See Table 1. Airflow is horizontal, both into and out
from the same face of the unit. The unit is designed to be
mounted indoors in a window, through the wall in high-rise
buildings, or on the wall on the building exterior. See Fig. 2
for typical applications. Ductwork is not needed, but may be
added easily if required by the application. Airflow is provided by centrifugal fans with an adjustable belt drive to meet
varying static requirements. Units may also be matched with
other compressor and evaporator combinations. Contact your
local representative for more details.
Check space requirements, service clearances, floor strength,
location of piping, size of power supply,and location of ductwork (if used) before installing. See Fig. 3 for unit dimensions and Table 2 for unit operating weights.
INSTALLATION
Step 1 — Complete Pre-Installation Checks —
Examine unit for damage incurred during shipment. File claim
immediately with transit company if damage is found. Check
the shipment for completeness. Verify that the nameplate electrical requirements match the available power supply.
Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
