Features/Benefits (cont)
Low-cost installation and
operation
Each unit is designed to occupy a
minimum space. No complex system
controls are required for Carrier fan
coil units. Piping, drain, and wiring
connections are readily accessible and
mounting holes and slots are pre-
drilled to save installation time and field
labor expense.
42 Series quality reduces
service and maintenance
expenses
Condensate drain pan is heavy gage
galvanized steel with closed-cell, fire re-
tardant foam insulation. Units come
standard with Tuf-Skin* II insulation for
energy savings, sound absorption and
indoor air quality (IAQ) preservation.
Water never touches the pan, so corro-
sion is minimized and long,
trouble-free life is assured.
