Carrier 51CV/GY - Manual (Page 6)

Timer pins are positioned inwards (toward center of
dial) from factory to allow continuous operation.
SETTING THE TIMER FOR AUTOMATIC ON/OFF
OPERATION
To set the timer, simply slide a pin outward from the dial’s
center for each hour (approximately) that you wish the
unit to be off.
CXDOLING EXAMPLE; You work days 8-4 and want the
unit off while you are at work, and cooling your room
when you arrive home at 5:00 p.m.
1) Slide the pins beginning at 8;00 a.m. through 3;00
p.m. on the dial, away from the center.
2) Switch the timer to AUTO setting.
Now the unit will automatically turn off at 8:00 a.m. and
start at 4:00 p.m. (an hour before you return home so
that the room where your unit is installed is cool and
refreshing).
You can program the timer similarly for the heating
operation.
NOTE: If timer’s switch is on MAN, timer setting will be
overridden and the unitwill run continuously.
You may adjust the cooling or heating speed
while unit is on AUTO, without changing your
timer’s setting.
The timer can be programmed to turn off and on,
one or more times during 24-hour period.
Vent Exhaust
AIR EXCHANGE
Your Carrier unit is equipped with vent and exhaust air
exchange systems. Use the following guide when
choosing the appropriate system;
Vent: Draws outside air into the room.
Exhaust: Expels stale, smoky or odor laden air from the
room to the outside.
For either system operation, push appropriate button
and turn cooling/heating mode dial to FAN ONLY
setting.
When air exchange is completed, return to normal
cooling or heating by pushing vent or exhaust button
again and rotating mode dial from FAN ONLY to desired
setting.
NOTE; Vent and exhaust usage is not recommended
during cooling or heating as these operations either vent
outside air into the room, or exhaust cooled or heated
air out,
REMEMBER; Button pushed in opens vent or exhaust
system. Button pushed out closes vent or exhaust
system.
AIR DIRECTION
Your 51 CV/GY unit has an Auto Air Circulator control
feature, allowing vertical air deflectors to move automa­
tically from left-to right for better air distribution around
the room. For straight forward air discharge, vertical •
air deflectors may be adjusted manually (with auto air
circulator switch in OFF position). The horizontal air
deflectors are also adjusted manually.
FAN CYCLE
OFF-
ON-
o
I — This setting lets fan cycle on and off with compres­
sor or electric heater. Fan stops when thermostat
setting is satisfied. This mode is recommended for
maximum comfort during heating operations, to
eliminate circulation of unheated room air by the
unit. When used in cooling, this mode results in
longer off time and wider variations in temperature
and humidity.
O — This setting allows continuous fan function, circu­
lating air even when compressor or heater has
cycled off and thermostat setting has been
reached. This mode is recommended for maximum
comfort during cooling operation.
Important HEAT/COOL Feature:
Drain Valve: Your unit has a thermostatically operated ^
drain valve located in its basepan. Valve remains closed M
in warm weather, channeling condensate to outdoor ^
coil to increase cooling efficiency. In cooler weather
(50°F or lower), valve automatically opens, draining
condensate and preventing possible ice build-up in
basepan. It may be necessary to re-direct drainage flow
in the winter to prevent possible build-up of ice on
pedestrian walkways. To re-direct drainage flow, an
Accessory External Drain Kit is available. Contact your
independent Carrier Dealer or call 1-800-CARRlER
for information.
