Overview
Installing the ICE AIR Horizontal FCU’s
involves two main components and various
accessory components.
Application Note
It is important for heating/cooling systems
to be properly sized for each application in
order to achieve desired temperature and
humidity levels. It is highly recommended
that a professional engineer match the FCU
you are about to install with the building
structure and climate.
Prerequisite
1. Locate the unit where it can evenly
distribute air throughout the room
without obstructions. Units should be
installed no closer than 18” apart when
two units are side by side. A vertical
clearance of 60” should be maintained
between units.
2. Adequate ceiling panel access must
exist for hanger brackets, duct collars
and fittings at water and electrical
connections
3. A minimum obstructed distance of 36”
should be kept around the unit.
4. Adequate and continuous water flow
must be maintained for proper and
safe unit operation. Ensure adequate
drainage is also available.
5. Dedicated electrical circuitry and power
supply is required to properly energize
the ICE AIR unit. Verify the amperage of
the dedicated electrical service to the
unit is correct and the unit can reach the

Installation
Installing the Unit
1. Ensure all preparations are met within
the “Pre-Requisite Section.”
2. Within the concealed ceiling, mark the
position of where threaded rods will
attach to. Refer to the submittal for
specific dimensions.
3 Embed four (4) threaded rods into the
indicated positions. Ensure the ceiling is
structurally intact to support weight of
the unit.
Refer to
table at right
for specific
weights.
4. Connect the
ICE AIR unit to
the threaded
rods through
the four (4) brackets on each corner.
Attach a Vibrational Isolator beneath the
bracket and a washer below that. Latch
these pieces in place with a hex nut.
Dual hex nuts are recommended as a
precautionary measure (see below).
5. Ensure the discharge vent is level,
elsewise adjust the threaded rods to
correct the unit. WARNING: Do not
loosen the nuts, this will increase the
chance of vibrational failure.
6. Attach all necessary pipes and wiring
connections. Additional ductwork should
only be installed if instructed.
7. (RECESSED) Fasten the Access Panel
to the bottom of the unit and tighten to
the unit. Ensure the open panel is not
fastened.
8. Run the unit.
Piping Installation
ICE AIRs Horizontal Concealed Fan Coil
is available in either 2 pipe or 4 pipe
configurations (see below) that are
connected to the system through the use
of a flexible hose or rigid pipe. The piping
system should be flushed to remove dirt,
pipe shavings, chips and other foreign
material prior to operation (refer to System
Cleaning and Flushing section). The flow rate
is generally set between 2 and 3 GPM per
ton of cooling for most applications of water
loop fan coils. To ensure proper maintenance
and servicing, P/T ports are imperative for
temperature and flow verification, as well as
performance checks.
Ducting Installation
If the system calls for ducting, attach the
duct to the duct collar on the supply vent. To
secure the duct, fasten to collar until there is
no exposed airflow (See below).
Filter Installation
Only configurations with a plenum on the
return vent for the Horizontal Concealed
Fan Coil are delivered with a filter. Filters
are placed on the bottom slot and pressed
forward into place.
Filter Replacement
The ICE AIR unit is delivered with a
Dispensable Filter. Dispensable Filters should
be replaced twice every year, before the start
of every heating or cooling season. Please
contact your local sales representative for
replacements.

System Cleaning and Flushing
Cleaning and flushing the unit is the most important step to ensure
proper start-up and continued efficient operation of the system.
Follow the instructions below to properly clean and flush the system:
1. Verify that electrical power to the unit is OFF.
2. Verify that supply and return riser service valves are closed at
each unit.
3. Fill the system with water, leaving the air vents open. Bleed all air
from the system, but do not allow the system to over flow. Check
the system for leaks and make any required repairs.
4. Adjust the water and air level in the expansion tank.
5. With strainers in place, start the pumps. Systematically check
each vent to ensure that all of the air is bled from the system.
6. Verify that make-up water is available and adjusted to properly
replace any space remaining when all air is purged. Check the
system for leaks and make any additional repairs if needed.
7. Set the boiler to raise the loop temperature to approximately
85°F (29.4°C). Open the drain at the lowest point in the system.
Verify that make-up water replacement rate equals rate of bleed.
Continue to bleed the system until the water appears clean or for
at least three hours, whichever is longer.
8. Completely drain the system.

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 AIRs examination shall prove to its
satisfaction that the part was or became defective under
normal use. ICE AIRs 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
or replacements unless specifically authorized in writing
by the Company.
The Company is not obligated under this warranty for
field labor such as service for inspection, removing,
packing and/or reinstalling water source unit, nor for the
return transportation charges.
OPTIONAL Extended Refrigeration
Circuit Warranty
The Optional Extended Refrigeration Circuit Warranty
MUST be purchased from ICE AIR within thirty (30) days
from date of delivery to be valid. The hermetically sealed
refrigeration circuit (consisting of the motor, compressor
assembly, evaporator coil, coaxial/condenser coil and
interconnecting tubing) is warranted to the original
owner for four additional years from date of the
expiration of the Twelve Month Warranty. Components
under this warranty will be supplied at ICE AIRs expense
provided the failed component is returned to the factory.
This optional warranty does not include any other parts
of the equipment such as fans, fan motors, controls,
cabinet parts, electrical relays, capacitors, protective
devices, or wiring. ICE AIR is not obligated under this
warranty for field labor such as service for inspection,
removing, packing, and/or reinstalling the refrigeration
circuit, nor for return transportation charges. 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 in warranty.

ICE AIR Customer Service at 80 Hartford Avenue, Mount
Vernon, New York 10553. Telephone [phone].
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 AIRs 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 AIRs 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 AIRs equipment
is installed in conjunction with cabinets, grills, louvers,
controls or other parts manufactured by others, these
warranties shall apply only to ICE AIRs manufactured
portion of the equipment. The conditions of the standard
warranty plan 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.
