Carrier 48HJF009 User Manual

Copyright 1999 Carrier Corporation Form 48HJ-11PD
Carrier has designed the Weather-
master series based on customer
needs and requests to be the most
efficient and reliable rooftop unit ever
made.
Features/Benefits
• Most efficient rooftop line for
cooling using scroll compressor
technology
• Most efficient rooftop line for
heating using dimpled heat
exchangers on all units
• High reliability — non-corrosive
condensate pans, prepainted
cabinets and primed interior
panels, and all units are fully
protected by internal safeties
• Quietest operation — all
compressors mounted on
independent vibration isolators.
Standard, belt-driven evaporator
fan motors on all units
• Ease of maintenance achieved by
self diagnostics on the Integrated
Gas Controller (IGC), optional
direct digital controls, standard
size filters, tool-less filter access,
simple compressor access,
permanently lubricated fan
motors, optional disconnect
switch, optional 115-v
convenience outlet, and optional
hinged access panels
• Exclusive MoistureMiser
dehumidification package — a
result of recent advances by
Carrier in controlling comfort
levels. This factory-installed
option significantly improves the
dehumidification capability of the
rooftop unit and helps control
humidity levels in the building.
