1. Overview
The Ice Air model ELA-13086 is a digital thermostat with a TFT
touch screen user interface (thin film transistor liquid crystal display;
TFT-LCD). It provides the user with control of heating or cooling
mode, temperature adjustment, 7-day programmable schedule, and
various working mode options. A time clock and calendar are integral
functions to this device.
2. Main Features
• Adjustable fan speed: High, medium, low, and auto. (2-speed or
3-speed can be set by the dip switch; 2-speed is the default)
• Optional mode: cooling, heating, auto and fan only. (heating
function can be set by the dip switch; the default assumes a
heating function present)
• Clock can be set to 12-hour (AM/PM) or 24-hour mode
• Calendar ranges: from 2020 to 2099
• 7-day programmable schedule (optional, set by the dip switch,
the default is “function available.” If the user wants to disable
the “7-day programmable schedule” they can do so via the
dip switch, which would cause the thermostat to operate like a
simple thermostat)
• Time delay function: 3 minute delay for compressor at first
power-on; (this can be using the dip switch; the default is delay
post start-up)
• System failure warning
• Heating mode: Set the heating mode type (hydronic coil heater,
electric resistance, heat pump, etc.) using the dip switch
• Space temperature sensor is integral to the thermostat; the
temperature sensing range is: 32°F to 99°F

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!
Indoor Air Filter
It is recommended that you clean the indoor
air filter after every 350 to 400 hours of
unit operation – more frequently if the unit
is running in an environment of high dust,
pet dander or other pollutants in the indoor
atmosphere.
Condensate Drain Pan and Drain Hoses
Check the unit condensate drain pan and
drain hoses annually to ensure proper
condensate drainage. If any foreign matter
build-up in the drain pan is found, clean the
drain pan and drain hoses – frequency of
cleaning depends on the level of dirt and
pollutants that may be present in the indoor
environment.
Evaporator Coil
Check and clean (if necessary) the unit
evaporator coil annually.
Evaporator Motor and Blower Assembly
Check and clean for dust and dirt build up as

water problem history, it is best to establish
a periodic maintenance program. It is the
building’s responsibility to maintain a water
system that should provide your unit with
treated and filtered water to keep water
flowing freely through your equipment.
With these simple maintenance procedures
carried out on a proper maintenance
schedule, your unit should provide many
years of trouble-free service. The procedures
are covered in greater detail on the following
pages and 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 – furniture, carpets and rugs, etc.
may restrict air movement.
• Keep the top of your cabinet free of
objects that may block air flow out of the
unit – plants, paperwork and books, etc.
should not be placed on or above the
discharge grille area.
• Keep drapes, blinds and other window
treatments clear of the air discharge
area – any blockage of discharge air will
have a negative impact on the unit and
on its ability to properly condition the
room.
General Unit Inspection
Visually inspect unit at least once a month.
Pay special attention to hose assemblies and
connections. Repair any leaks and replace
deteriorated hose immediately to avoid
potential costly damage to your property due
to component failure.

Precautions and preparations listed are for general knowledge and to define basic guidelines. Local codes and existing practices should be observed and preformed by a professional.

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.
Condenser (Water
Heat Exchanger)
Generally, if water
flow exceeds 3 gpm
per ton, the water
velocities should
keep your coil free of
scaling of debris that
could lead to erosion
and fouling.
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 additional
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.
Roomside Component Cleaning
IMPORTANT: Power MUST be disconnected
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. Remove the unit front cover/access door
by unscrewing the retaining screws
that hold it in place. You will then have
access to the unit components.
NOTE: Pictures of components and parts
may vary depending on your model.
Air Filter
1. Remove Air Filter.
2. If reusable, wash Air Filter in warm water
and biodegradable cleaner.
3. Rinse with clean water and allow to dry
completely.
4. Replace Air Filter.
5. As an alternate cleaning method, the
filter may be cleaned on both sides using
a vacuum cleaner and a soft brush type
attachment.
6. If your filter is disposable, replace with
new filter.
IMPORTANT: Do not operate unit without
filters.

Twelve (12) Month Warranty of Ice Air units – Ice Air,
LLC, herein referred to as “Ice Air,” warrants to the
original owner that the entire unit is free from defects
in material and workmanship for a period of twelve (12)
months from the date of delivery. Any part of portion
thereof which becomes defective under normal use
during the period of this warranty will be repaired or
replaced provided Ice Air’s examination shall prove to its
satisfaction that the part was or became defective under
normal use. Ice Air’s obligations under this warranty
are limited to: (a) Repairing the defective part or (b)
furnishing a replacement part provided the defective
part is returned to the factory, without shipping damage,
transporting charges prepaid. No reimbursement will be
made for expenses incurred in making field adjustments

The Twelve Month and the OPTIONAL Extended
Refrigeration Circuit Warranty (which must be purchased
separately) constitute the buyer’s sole remedy. They are
given in lieu of all other warranties. There is no implied
warranty of merchant-ability or fitness for a particular
purpose. In no event and under no circumstance shall
Ice Air be liable for incidental or consequential damages,
whether the theory is breach of this or any warranty,
negligence, or strict tort.
No person (including any agent, salesman, dealer or
distributor) has authority to expand Ice Air’s obligation
beyond the terms of these express warranties, or to
state that the performance of the product is other than
that published by Ice Air.
General Conditions
The above warranties are void if Ice Air’s equipment has
been damaged, misused, subjected to abnormal use or
service or its serial number has been altered, defaced,
or removed, or payment for the equipment is in default.
Ice Air is not responsible for service to correct conditions
due to misapplication, improper installation, inadequate
wiring, incorrect voltage conditions or unauthorized
opening of the refrigeration circuit, nor for consequential
damages. In case Ice Air’s equipment is installed in
conjunction with cabinets, grills, louvers, controls or
other parts manufactured by others, these warranties
shall apply only to Ice Air’s manufactured portion of the

are effective for 18 months from TCO. Ice Air reserves
the right to make a handling and inspection charge in
the case of parts or equipment improperly returned as
defective and/or as being warranty.
Important
The following are the responsibility of the user. They
are not manufacturing defects, and are therefore not
included in the warranty plan.
1) Failure of unit to operate satisfactorily due to
improper amount of air on evaporator coil or air
supply to air cooled condensers.
2) Damage to unit or unsatisfactorily operation due to
improper cleaning of evaporator coil or use of unit
in corrosive atmosphere locations such as chemical
plants, refineries, or salt spray areas.
3) Damage to unit from unsatisfactory operation due
to blown fuses, inadequate or interrupted electrical
service, use of improper electrical protective devices
or operation of unit on power supply other than
covered by nameplate rating of unit.
4) Damage due to failure to properly maintain unit.
5) Damage due to transportation or handling prior to and
during installation.
6) Damage due to accident or from alteration, improper
installation, tampering.
7) Filter cleaning or replacement.
8) Misapplication.
Check, Test and Start
Check, Test and Start of the air conditioners by an
experienced person is the responsibility of the installing
contractor. This consists of physically confronting each
unit operating in both heating and cooling modes and
correcting any minor deficiencies noted. After the
equipment leaves the factory, it may become damaged
or maladjusted during transportation or on the job.
Sometimes wires are disconnected accidentally, or fan
motors move on their bases due to rough handling,
causing fans to strike; a component(s) may be
inoperable. The correction of such conditions is part of
the Check, Test and Start. Note that unless otherwise
specifically agreed to in writing, Ice Air includes no field
labor, Check, Test, and Start (or the like) in the price of
its equipment.
Installation
Ice Air is not responsible for the design, execution
and performance of the installation method or any of
the accessory items used during installation such as
seals, caulking, weatherproofing, supporting structures,
attachment means, louvers and frames supplied by
others.
