A NOTE ABOUT SAFETY
Any time you see this symbol in manuals, instructions and on the unit, be
aware of the potential for personal injury. There are 3 levels of precaution:
1. DANGER identifies the most serious hazards which will result in
severe personal injury or death.
2. WARNING signifies hazards that could result in personal injury or
death.
3. CAUTION is used to identify unsafe practices which could result in
minor personal injury or product and property damage.
NOTE is used to highlight suggestions which will result in enhanced
installation, reliability, or operation.
GENERAL
The Air Handler fan coil unit provides quiet, maximum comfort. In addition to
cooling and/or heating, the Air Handler fan coil unit, matched with an outdoor
condensing unit, filters and dehumidifies the air in the room to provide
maximum comfort.
IMPORTANT: The Air Handler fan coil unit should be installed by
authorized personnel only; using approved tubing and accessories. If
technical assistance, service or repair is needed, contact the installer.
The Air Handler fan coil unit can be set up and operated from the remote
control or the wired controller (both provided).
Operating Modes:
The Air Handler fan coil unit has four operating modes:
• FAN ONLY
• AUTO
• HEATING
• COOLING
FAN ONLY
In the FAN ONLY mode, the system filters and circulates the room air
without changing the room air temperature.
AUTO
In the AUTO mode, the system automatically cools or heats the room
according to the user-selected set point.
NOTE: AUTO mode is recommended for use on single zone
applications only. Using AUTO changeover on multi-zone applications
could set an indoor unit to STANDBY mode, indicated with two dashes (-
-) on the display, which turns the indoor unit off until all the indoor units
are in the same mode; either COOLING or HEATING.
NOTE: HEATING is the system’s priority mode. Simultaneous
HEATING and COOLING is not allowed.
HEATING
In the HEATING mode, the system heats and filters the room air.
COOLING
In the COOLING mode, the system cools, dries and filters the room air.
PERSONAL INJURY, DEATH AND / OR PROPERTY
DAMAGE HAZARD
Failure to follow this warning could result in personal injury,
death or property damage.
Improper installation, adjustment, alteration, service,
maintenance, or use can cause explosion, fire, electrical shock, or
other conditions which may cause personal injury or property
damage. Consult a qualified installer, service agency, or your
distributor or branch for information or assistance. The qualified
installer or service agency must use factory-authorized kits or
accessories when modifying this product.
