Consumer Reference Information
For safe and optimal enjoyment of your ICE AIR unit, please read
the following consumer safety and operating notes carefully before
operating your equipment!
p
! RECOGNIZE THIS SYMBOL AS A SAFETY PRECAUTION.
p
!WARNING: ICE AIR will not be responsible for any injury or
property damage arising from improper service or service
procedures. If you install or perform service on this unit, you
assume responsibility for any personal injury or property
damage which may result. Many jurisdictions require a license
to install or service heating and air conditioning equipment.
p
!WARNING HIGH VOLTAGE: Disconnect all power before
servicing or installing unit. Multiple power sources may be
present. Failure to do so may cause property damage,
personal injury or death.
Safety Guidelines
Read this entire manual before operating the unit.
p
!WARNING: This unit MUST be serviced only by professionally
trained, qualified technicians. Do NOT attempt to maintain or
service this unit on your own – severe injury and death can occur
from electric shock, moving parts, and other hazards.
• Your ICE AIR unit must be properly installed and commissioned
to operate correctly. Improper unit installation, adjustment or
commissioning, and/or improper heating system installation and
connection can lead to equipment malfunction and hazardous
operating conditions, and may void your warranty. If you have
any doubt about the proper installation of your ICE AIR unit,
please contact your property manager at once to have a qualified
technician inspect the equipment.
• Our ICE AIR units must each be wired on an individual, dedicated
electrical circuit with the correct voltage and proper amperage
(capacity) to match the unit nameplate requirements.
• Each unit’s electrical circuit must have a proper overcurrent
protection device, employing an approved circuit breaker or fuse
of the proper rating under NEMA and local building codes.
p
!WARNING: Do NOT operate the unit with frayed, burnt or
damaged electrical wires!
p
!WARNING: Do NOT operate the equipment when in doubt –
have it inspected first!
IMPORTANT: It is not the intent of this maintenance manual to
correct any installation deficiencies. If you have any doubt about the
proper initial installation (or reinstallation after servicing) of your
ICE AIR unit(s) – noisy or inefficient unit operation, frayed or damaged
electrical connections, improper unit appearance, etc. – please
contact a trained servicer or building maintenance staff immediately.
The following physical conditions must be maintained for
proper unit operation:
Air flow must be unobstructed into and out of the unit room enclosure
(cabinet). Therefore:
• Do not place any object directly in front of the discharge grille
(at the cabinet top).
• Do not place plants, fabrics or objects in front of the air return
access door.
• Have the unit filter properly cleaned and serviced to prevent air
blockage from dirt and dust within the filter media.
Intended for indoor use only.
Proper installation and operating environment must be maintained.
Therefore:
• Do not operate the unit in corrosive environments such as
chemical plants, refineries or salt spray areas.
• Operate only with proper electrical service and protective circuit
breakers or fuses in place.
• Operate only with all unit and enclosure sheet metal parts in
place and properly installed.
• In areas of high concentrations of dirt, dust, pet dander or
pollutants, clean the filter often (at least monthly).
• Do not clean the unit with any solvents or cleaning solutions that
may damage the equipment.
• Understand and follow the unit operating instructions before
using your ICE AIR equipment.

Sequence of Operations – Fan Coil
Manual Heat/Off/Cool System Switch: A System Heat/Off/Cool
Switch, located on the thermostat’s cover, shall allow the operator
to manually select the Heating or Cooling mode of operation or to
disable the fan and control valve in the “Off” position. The fan shall
run continuously with the system switch in the Heat or Cool mode
(On) and shall stop when the system switch is placed in the “Off”
position.
Auto Seasonal Changeover (ASC): A Auto Seasonal Changeover
switch mounted on the inlet piping to the fan coil, shall sense the
temperature of the water to determine whether the valve should be
open or closed.
If the switch is in Cooling mode and inlet water temperature is below
85°F, the Auto Seasonal Changeover switch shall open the valve
and allow cool water to circulate through the system else the valve
remains shut to prevent hot water from flowing through and heating
the space in cooling mode.
If the switch is in Heating mode and inlet water temperature is above
85°F, the Auto Seasonal Changeover switch shall open the valve
and allow hot water to circulate through the system else the valve
remains shut to prevent cold water from flowing through and cooling
the space in heating mode.
Cooling Mode: With the ASC switch in the Summer (Cooling)
position, the Heat/Cool thermostat shall cycle the water control valve,
via the thermostat’s cooling signal, to maintain the desired space
temperature in reference to the thermostat’s set point.
Heating Mode: With the ASC switch in the Winter (Heating) position,
the Heat/Cool thermostat shall cycle the water control valve, via
the thermostat’s heating signal, to maintain the desired space
temperature in reference to the thermostat’s set point.
Variable Fan-Speed:
Heating Only Mode
• High speed fan will run when room temperature is less than 4°
below set temperature
• Low speed fan will run when the room temperature is less than
or equal to 2° below the set temperature
• Fan speeds throttle from High speed to Low speed when
transitioning from a difference of 4°F to 2° of the set
temperature
• The fan will shut off when the room temperature meets the set
temperature.
Cooling Only Mode
• High speed fan will run when room temperature is higher than
4°F below set temperature
• Low speed fan and the compressor will run when the room
temperature is higher than or equal to 2°F of the set temperature
• The fan will shut off when the room temperature meets the set
temperature.

Maintenance
Your ICE AIR unit is designed to provide
many years of efficient, trouble-free comfort
conditioning service. To ensure equipment
longevity and efficiency, please make sure
that the following simple maintenance
procedures are followed. This manual
assumes that your unit has been installed
by a qualified installation professional, and
is operating properly prior to maintenance
service.
Have your unit periodically inspected by
a properly trained service professional or
building maintenance staff person. The unit
should be checked for the safe and proper
functioning of all of its systems at least
once a year. The following recommended
maintenance procedures should be carried
out only by trained personnel with strict
adherence to the Safety Guidelines outlined
at the beginning of this manual. These
procedures MUST be followed to ensure
your safety and the safety of the person
maintaining the equipment!
Component Cleaning
p
!IMPORTANT: Power to the unit must
be turned off at the electrical breaker
before carrying out any of the following
cleaning!
To access the components within the chassis
of the unit:
1. Unit must be in OFF Position.
2. Disconnect unit from power source.
3. Access to internal components may vary
based on installed conditions.
NOTE: Pictures of components and parts
may vary depending on your model.
Indoor Air Filter (if applicable)
Only configurations with a plenum on the
return vent for the ICE AIR unit are delivered
with a dispensible filter. Filters are placed
on the bottom slot and pressed forward into
place (installed filter shown above).
Dispensable Filters (shown above) should be
replaced twice every year, before the start
of every heating or cooling season. Please
contact your local sales representative for
replacements.
Evaporator Coil
Check the coil for cleanliness and uniformity
of fins. If the coil is dirty, vacuum clean with
a soft brush attachment. This is the only form
of cleaning that should be carried out within
an apartment. If the coil requires addi-
tional cleaning, the unit must be removed
and cleaned using compressed air and/or
washed. These operations MUST be carried
out in a facility properly equipped to handle
this type of work in a safe and professional
manner.
Evaporator Motor and Blower Assembly
If there is evidence of dirt or dust build-up in
the evaporator motor or blowers, they should
be cleaned either by vacuum cleaning (if
working in an apartment) or by removing the
unit to a workshop location and cleaning with
compressed air.
p
!WARNING: Always obey safety
guidelines for using compressed air
in this latter case.
Your ICE AIR unit has permanently lubricated
motor bearings that do not require additional
lubrication. Blowers and motors are factory
assembled for quiet performance – if there
is any excessive noise and vibration from this
assembly, it should be serviced by a qualified
technician.
IMPORTANT: Do not operate unit without
filters.

With these simple maintenance procedures
carried out on a proper maintenance
schedule, your unit should provide many
years of trouble-free service. The procedures
should be implemented by trained personnel.
But, there are certain items that you, the
apartment owner or tenant, can do to ensure
proper unit function:
• Keep the area around your unit clear of
objects that may block air flow into the
unit.
