Chapter 1: Introduction
Thank you for choosing a unit manufactured by AIRSYS.
The AIRSYS UNICOOL line of wall mounted HVAC systems is optimized for energy efficient removal of
heat generated by electronics from enclosed shelters. All units are equipped with variable speed inverter
compressors, variable speed EC fans, and an advanced control system that increases system efficiency
while reducing wear and tear.
Another feature that promotes energy efficiency is the robustly designed integrated economizer,
described as “free cooling”. This feature, when conditions are suitable, provides 100% of the rated cooling
capacity of the wall pack unit (WPU) while consuming ~ 1kW or less whenever the outdoor temperature is
a few degrees lower than a predetermined setpoint. This feature alone can save equipment shelter
operators significant utility costs, especially in cooler climates.
In addition to having excellent energy efficiency, these systems are simple to operate, maintain, and
service. The AIRSYS design team is committed to listening and responding to the customer community. As
a result, these systems have continuously evolved with customer-defined features that have improved the
overall quality and the user experience.
Usability features include:
•A functional step test that facilitates complete operational verification in less than 5 minutes
•Unobstructed access to all key components for Preventive Maintenance (PM) and servicing
•A high level of operational reliability via the built in Fail-Safe mode
•Completely selectable alarm relays (NC or NO) to enable the system to adapt to the customer’s
requirements
•In depth real-time system parameter readings available remotely and on site.
•Real-time power monitoring for individual units
The AIRSYS UNICOOL WPUs are available in cooling capacities from 1.5 - 10 tons; however, the sensible
cooling capacity of these machines is as much as 40% higher than a traditional machine. An available
ordering guide can help properly match the capacity of the HVAC system to the heat load in the shelter.
With a suite of best in class components from around the globe, AIRSYS UNICOOL WPUs deliver quality
and reliability while substantially reducing cost of operation.

Chapter 2: Product Overview
The air conditioning system has three key components: the mechanical cooling system, the free cooling
system (economizer), and the control system. The control system determines the unit’s mode of
operation: free cooling or mechanical cooling, as shown in Figures 2 and 3.

Free Cooling System
When the operating conditions for free cooling are met, the control system switches the air damper to the
free cooling position. Cooler air from outside is delivered to the shelter by the supply air fan. At the same
time, hot air in the shelter is discharged to the outdoor environment.
Adaptive Free Cooling
Traditional Wall Packaged Unit control provides a fixed outdoor temperature where free cooling starts
based on indoor setpoint. With adaptive free cooling, the system will automatically learn and remember
the optimal temperatures where free cooling can take over. Adaptive free cooling will continuously
optimize toward free cooling hours with no human adjustment required. This is particularly valuable
whenever the site heat load changes as the system will also adapt to find the new optimal free cooling
setpoints.
Mechanical Cooling System
When the operating conditions for mechanical cooling are met, the control system switches the air
damper to the mechanical cooling position. The compressor compresses the refrigerant gas and sends it
to the condenser. The condenser is a heat exchanger, removing heat from the hot compressed gas and
allowing it to condense into a liquid. The liquid refrigerant is then routed to the thermal expansion valve,
which acts as a restriction device by forcing the refrigerant to go through a small hole. This causes the
pressure to drop. Then the liquid refrigerant is routed to the evaporator. The evaporator is also a heat
exchanger, absorbing heat from the indoor hot air causing the liquid refrigerant to change back into gas.
The refrigerant gas is then routed back to the compressor to complete the cycle. The refrigerant is used
repeatedly, absorbing heat from the indoor environment and discharging heat to the outdoor
environment.
Soft Start
When mechanical cooling is requested, the compressor will ramp up its capacity and continuously
modulate it to match the required site load. This minimizes mechanical stress upon startup, eliminates
startup voltage spikes, and reduces unit noise level.
The Control System (ASMUC.6 Controller)
By default, the ASMUC.6 controller can control up to 6 AIRSYS Precision Cooling WPUs (16 with expansion
module) organized in up to 4 zones. The setpoint for each zone can be adjusted independently.
The controller box is factory programmed with standard industry setpoints but can be configured on-site
or remotely to meet specific needs. Settings are retained in the event of a power loss. In addition, all
WPUs have integrated control modules that are the same as those in the controller box. If communication
between the units and controller is lost, the units will cool independently using the last given controller
settings and information from onboard temperature and humidity sensors.

Email: [e-mail] Web: http://airsysnorthamerica.com Rev 1.15
Ease of Control and Configuration
The controller is controlled through the Programmable Graphical Display (PGD) interface. The PGD and
button actions are explained in more detail starting on Page 45. Using the PGD interface, the user can:
•Check the status of the HVAC system, such as sensor readings and operating mode
•Change factory setpoints
•Place the system temporarily into comfort mode
•Review alarms and alarm history
Labeling on the outside of the controller box provides a convenient guide on how to access the most
common functions. The same functions can be accessed remotely via an IP communication interface built
into the controller. The units are also pre-wired to allow for a PGD to connect directly to the unit, allowing
for testing and configuration directly from the unit.
Synchronized Cooling
When mechanical cooling is required to maintain the site temperature, all available units will run at low
speed as opposed to one unit taking the full load. This increases overall system efficiency and reduces
wear and tear on the compressor. If one of the units is taken offline, the others will adjust their speeds
accordingly to maintain the site temperature.
Standalone Mode
The system can operate in fully functional Standalone Mode when communication is lost between HVAC
and controller. This includes including free cooling, mechanical cooling, dehumidification, and heating.
This eliminates the controller as a potential single point of failure for the HVAC system.
Heat Load Matching
The variable capacity units can adjust the compressor run speed to exactly match the heat load as
opposed to cycling on and off to maintain a setpoint. Since most of the component stress occurs during
startup and shutdown, heat load matching increases overall system reliability and efficiency.
Turbo Boost
In situations such as extreme outdoor temperature, the heat load of the building may exceed the nominal
cooling capacity of the system. In those cases, Turbo Boost can automatically overdrive the units to
provide up to 125% of the rated capacity at the cost of some efficiency.
Quiet Mode
Quiet mode reduces noise by 10-14 dBA by limiting the maximum speed that the compressor can run at.
In doing so, the maximum cooling capacity will be reduced by ~15% and Turbo Boost will be disabled.

Chapter 3: Installation
Installation Preparation
Unpack the unit carefully. Some parts are packed loosely and may move as the packaging is opened.
Before discarding the box, check the packaging carefully for any parts or documents inside. Refer to Table
3 on Page 16 for the complete list of materials shipped with each unit.
Check that:
The supply voltage meets the requirements as designated: 197-252VAC, 36-57VDC.
•The install location is clean on the inside and free of excess dirt and dust.
•Minimum install clearances are met (see “Clearances”on Page 20).
•All installer provided items, listed in Table 4 on Page 18 are accounted for.
Installation and startup must be performed by an AIRSYS Authorized Service Technician (AAST). For more
information about the AAST program, please contact:
AIRSYS North America
[e-mail]
855-874-5380
Danger. All the installation work must be done by professional technicians. Installation that does
not comply with the instructions herein can result in the loss of warranty coverage. AIRSYS shall not
be held liable for any damage caused to persons or objects due to incorrect installation or operation of
the units.
Warning. All wiring must comply with the local safety standards and building codes under all
circumstances.
Warning. Risk of electric shock can cause injury or death: disconnect all remote electric power
supplies before installation.
When no longer in use, disposal of equipment and materials must be compliant with local laws and
standards.
Delivery
When the units are delivered, be sure to inspect them to verify that they have not been damaged during
transport. Also verify that all requested accessories listed on the purchase order have been included.
Important. If packages show any signs of shipping damage or potential shipping damage, it is
very important to annotate shipping damage on the Bill of Lading prior to signing for the freight.
In order to recover for any damage, please take detailed photographs of all the packaging before the
external packaging is removed. Once detailed photos of the external packaging have been taken, then the
external packaging may be removed so the items can be inspected further. Please document with photos

Contact: AIRSYS North America Phone: [phone] Page 15 of 112
Email: [e-mail] Web: http://airsysnorthamerica.com Rev 1.15
any damage to the equipment that relates directly to the damage observed to the external packaging.
Without the detailed photos, it will be very difficult to recover equipment loss.
Warranty
The warranty duration is 12 months from the date of installation. AIRSYS warrants that its products will be
free from defects in materials and workmanship for a period of 12 months after installation.
The compressor is to be free from defects in material or workmanship for a period of 60 months from
date of installation.
Important. For sites equipped with a generator, when the generator switches to the primary
source of power, the instantaneous voltage may become lower. If this is the case, the compressor
may run at a lower voltage which can decrease the compressor’s working life. Make sure the Gen-Run
signal input is connected which can protect the compressor. The warranty does not cover damage to the
compressor caused by repetitive out of specification supply voltage during compressor operation.
AIRSYS will furnish free of charge replacement parts for any component failures that occur within the
warranty period. Customer is responsible for the cost of shipment of replacement material from AIRSYS
North America.
Note: Warranty assumes that an AAST performs the installation and submits the warranty registration
card that accompanied the units in shipment. If the warranty registration card was not filled out and
returned to the supplier, then the warranty will be assumed to expire 12 months from the date of
shipment for all components except the compressor, which will be assumed to expire 60 months from
date of shipment.
This warranty does not cover damage to the systems caused by misuse or abuse of the systems such as
physical damage due to mishandling. The warranty does not cover damage caused by force majeure.
Important. Any mishandling of the equipment or modifications to the equipment, unless agreed
upon in writing by AIRSYS, will void the warranty.
Moving the Unit
Forklifts are recommended for moving, loading, unloading, and positioning the WPU for installation. If
bands or ropes are used to create a sling, make sure that excessive force is not applied to the upper
edges of the machines or the package to avoid cosmetic or material damage. When using spacing bars,
protective materials are required around the units to prevent damage. To avoid damage to the units while
moving or transporting, ensure the units always remain in the upright position.
Note: The 28V1B5 unit may not be compatible with pallet jacks due to low pallet height. Loading dock
facilities or lift gate equipped vehicles are recommended when transporting the unit.
Note: A crane will be required to lift the 28V1B5 unit during installation due to its weight (1370 lb/621
kg).
