This manual contains safety instructions that must be followed during installation and maintenance of the unit. Read this manual before
installing or operating this unit.
NOTE: Installation and maintenance should be performed only by qualified personnel who are familiar with local codes and regulations
and who have experience with this type of equipment.
! DANGER !
LOCK OUT/LABEL all power sources before starting, pressurizing, depressurizing or shutting down the chiller.
Disconnect electrical power before servicing equipment. More than one disconnection may be required to deenergize the unit. Fail-
ure to follow this warning to the letter can result in serious injury or death. Be sure to read and understand the installation, operating
and service instructions in this manual.
!DANGER !
Danger indicates a dangerous situation which, if not avoided, will result in death or serious injury.
!WARNING !
Warning indicates a potentially dangerous situation which may result in property damage, personal injury or death if not avoided
! CAUTION !
Caution indicates a potentially dangerous situation which may result in minor injury or equipment damage if not avoided.
! WARNING !
Electric shock danger. Improper handling of this equipment can cause personal injury or equipment damage. This equipment must
be properly grounded. Control panel connections and maintenance should be performed only by personnel knowledgeable in the
operation of the equipment being controlled. Disconnect electrical power before servicing equipment. Be sure to install a earth
leakage breaker. Failure to install a earth leakage breaker may result in electric shock or fire.
!WARNING !
If refrigerant leaks from the unit, there is a potential choking danger as the refrigerant will displace air in the immediate area. Be
sure to follow all applicable published industry-related standards and local, state, and federal statutes, regulations, and codes if
refrigerant is produced. Avoid exposing refrigerant to an open flame or other ignition source.
! WARNING !
Polyolester oil, commonly referred to as POE oil, is a synthetic oil used in many refrigeration systems and may be present in this
Clima Flex product. POE oil, if it ever comes in contact with PCV/CPVC, will coat the inside wall of the PVC/CPVC pipe and cause
environmental stress fractures. Although there is no PCV/CPCV pipe in this product, keep this in mind when selecting piping mate-
rials for your application, as system failure and property damage could occur. Consult the pipe manufacturer’s recommendations to
determine appropriate pipe applications.
!CAUTION !
Static sensitive components. Static discharge during handling of the electronic circuit board can cause damage to components.
Use a static strap before performing any service work. Never unplug any cables, circuit board terminal blocks, or power plugs while
power is applied to the panel.
!CAUTION !
When moving refrigerant to/from the cooler using an auxiliary tank, a grounding strap should be used. An electrical charge builds
up when halo-carbon refrigerant travels in a rubber hose. A grounding strap should be used between the auxiliary refrigerant tank
and the cooler end sheet (ground to ground), which will safely carry the charge to ground. Failure to follow this procedure may result
in damage to sensitive electronic components.

EFFICIENCY
Our units are designed to meet the needs of any project.
Our intelligent process controllers and smart temperature sensors
provide maximum performance and energy savings.
The system automatically modifies the operating mode to maintain
optimum system conditions, making it very easy to operate.
All temperature sensors are calibrated and adjusted at the factory
prior to shipment. Start-up should be performed by a qualified
technician, during initial start-up the unit will be adjusted to local
conditions and all operating points will be checked.
Once the unit has been set up, operation is a matter of pressing
the start/stop button until it is certain that the unit is operating
properly.
After this the unit will operate automatically, turning itself on
according to the demand of the refrigeration system and local
conditions.

The units feature intelligent processors and sensors that
automatically control the temperature at optimum operating
conditions.
The units were designed to be coupled with each other and
combined to meet different load variations (Tandem Installation).
Up to 10 modules can be combined; these combinations can be
made with Water Chiller Units of different capacities ranging from
25 to 250 tons. Capacities vary depending on the number and
type of units.
SAFETY
All structures are made of galvanized sheet steel, coated with
electrostatic baked-on paint to ensure long durability and freedom
from corrosion under all weather conditions, such as direct
sunlight, rain and wind.
All units are designed to fit into a small installation space, thus
eliminating large installation areas. We use only high quality
components to ensure durability and safety even in harsh
environmental conditions.
NOTE: For applications in tropical climates our units are
coated inside and out with corrosion protection

Our products have AHRI efficiency certifications and ETL safety
certifications, in addition to meeting all industry safety standards.
We are members of the American Society of Heating,
Refrigerating and Air-Conditioning Engineers (ASHRAE). To
show our commitment to our customers and stakeholders; our
equipment comes with a 1 year major warranty after start-up.
Our units use R410A refrigerant, which is harmless to the ozone
layer and is non-toxic and non-flammable, even in case of leakage.
Finally, the efficiency of the heat exchanger and its modular
design allow for quick and easy installation.
DESIGN
Research conducted by the Engineering Department has resulted
in units with high design efficiency and optimum performance.
The selection of the main components, our quality and control
system guarantee high performance and safety.
All major components are rigorously tested and qualified before
installation. Each designed unit has undergone long hours of
rigorous testing to ensure the safety, durability and quality of the
entire system.
COMMUNICATION
The units can be controlled in tandem mode and/or can be
connected to a central control unit. Operation and user access
will be through a 7” color touch screen.
Our units can be managed through different communication
protocols; such as Modbus and BACnet, the most commonly used
protocols in the Air Conditioning industry.
Our units keep track of all programmable variables in real
time, such as performance monitoring, specific alarms of the
refrigeration cycle and the electrical system; as well as detection
of external factors such as fire or flood (optional sensors).
The control and monitoring system ensures the correct operation
of the unit by monitoring in real time the condition of the major
components (high or low refrigerant pressure, compressor and
fan motor conditions, etc.).
In case of failure, the event will be recorded for later analysis,
facilitating the localization of a possible failure and its solution.
INSTALLATION
The units have been designed for easy installation. Screw
connections provide easy installation of the water piping, which
are located on both sides of the unit, so that the piping can be
connected to either side of the unit.
The individual assembly of the units reduces installation cost, the
units have a rigid base that balances the weight of the unit and
allows for easy installation.
MAINTENANCE
The simplicity in the design of each unit allows for maximum
ease of maintenance. All major components are available to
maintenance personnel by simply opening the service panel.
If an emergency shutdown occurs, the control section will indicate
in detail the cause of the failure, helping to facilitate and accelerate
troubleshooting.

Coating is a flexible, water-based, water-reducible, synthetic
polymer corrosion coating designed specifically for the protection
of HVAC/R coils and components. Insitu® Spray Applied Coating
contains ES2 (embedded stainless steel pigment) technology, an
anti-corrosion coating specifically designed for the protection of
coils mounted in corrosive areas.
HVAC/R coils, components and enclosures will have a permanent
water-based synthetic coating with ES2 pigment applied to all
areas of the coating surface with no bridging of material between
fins. Therefore, ES2 pigments are suitable for even the most
corrosive environments and will maintain their appearance after
many years of exposure. UV degradation ES2 pigments form a
multilayer structure throughout the paint film.
This creates a barrier layer that reflects sunlight away from the
paint film preventing UV rays from penetrating. As a result, UV
degradation of individual polymer molecules is eliminated, film
integrity is maintained and the pigment particles remain well
anchored to the substrate.
The resulting smooth, hard finish prevents dirt build-up. The
multilayer structure of ES2 pigments delays the passage of water
molecules into the film and acts as an effective moisture barrier.

The unit nameplate is located on the outside of the unit power
panel. Both the model number and serial number are located on
the unit nameplates; the serial number is unique to the unit.
These numbers should be used to identify the unit in case of
service, parts or warranty questions. This nameplate also
contains the unit’s refrigerant charge and electrical ratings. The
evaporator nameplate is under the insulation and contains the
serial number. The compressor nameplate is located on each
compressor and provides pertinent electrical information.
! WARNING !
Installation should be performed by qualified personnel who
are familiar with local codes and regulations.
Check all items carefully against the bill of lading. Inspect all
units for damage upon arrival. Report shipping damage and file a
claim with the carrier. Check the unit nameplate before unloading,
making sure it matches the available power supply.
Clima Flex is not responsible for physical damage that occurs
after the unit leaves the factory.
Take care to avoid rough handling of the unit. Do not push or pull
the unit from other than the base while seated on properly sized
dollies.
To lift the unit, 2-1/2 (64 mm) diameter lifting eyes are provided
at the base of the unit. Arrange the spreader bars and cables to
prevent damage to the condenser coils or cabinet (see Figure 1).
! CAUTION !
All lifting locations must be used to avoid damage to the unit.

The inside of the base rail is open to allow access to secure
mounting bolts, etc. Mounting location dimensions are indicated
on the dimensional drawing on page 15 . All compressor bolts,
rubber, grommets and fasteners should be left in place in the
base. None of these fasteners are considered “temporary
shipping bolts”.
The control panels are located at the end of the chiller and require
a minimum clearance of 1.2 meters in front of the panels. The
compressor, filter-driers and line shutoff valves are accessible on
each side or end of the unit. Do not block access to the sides or
ends of the unit with piping or ductwork.
Sufficient distance must be maintained between the unit and
adjacent walls to allow the required airflow from the unit to reach
the coils. Failure to do so will reduce capacity and increase
energy consumption.
The clearance requirements shown are a general guide and
cannot take into account all scenarios. Factors such as prevailing
winds, additional equipment within the space, outside air
temperature and many other factors may require more clearance
than shown. Additional clearances may be required under certain
circumstances.
The graphs on the following pages indicate the minimum
clearance for different types of installations and also the reduction
in capacity and increase in power if a smaller space is used. The
graphs are based on individual cases and should not be combined
with other scenarios.

! CAUTION !
The performance of the unit may be affected if the operating
clearance is not sufficient.
The use of spring isolators is recommended for roof applications.
For ground level applications, install the unit on a solid base that
will not settle.
Use a one-piece concrete slab with a foundation extended below
the frost line.
Ensure that the foundation is level to within 13 mm over its entire
length and width.
The foundation must be strong enough to support the weight of
the unit ( see “Dimension and Weight - Packaged Unit” on page
15.)
The addition of neoprene pads (customer supplied) under the unit
allows water to drain from inside the frame, which can act as a
dam. Installing optional spring or rubber isolators in the shear can
also aid drainage, see page 19 for information.
Figure 2. Building or wall on one side of the unit.
Case 1. Open protection walls
Decorative walls are often used to help conceal a unit, either on
the ground or on the roof. Whenever possible, design these walls
so that the combination of their open area and distance to the unit
does not require a performance adjustment.
If the percentage of wall openness is less than recommended for
the distance to the unit, it should be considered a solid wall. The
wall height is assumed to be equal to or less than the height of the
unit when mounted on its base bracket.
If the wall height is greater than the unit height, (refer to Case 2:
Pit Installation) for performance adjustment factors. The distance
from the sides of the unit to the side walls must be sufficient for
service, such as opening the control panel doors.
In the case of uneven wall separation, the distance from the unit
to each wall can be averaged as long as no distance is less than
4 feet. Values are based on walls on all four sides.
Case 2. Pit installation
Pit installations can cause operating problems due to recirculation
and air restriction and require that sufficient air separation be
provided, safety requirements be met, and service access be
provided.
A solid wall surrounding a unit is substantially a pit and this datum
should be used. Sometimes a steel grating is used to cover a pit
to prevent accidental falls or trips into the pit.
The grate material and installation design should be strong
enough to prevent such accidents, but should provide plenty of
open area to prevent recirculation problems.
Have the Clima Flex sales representative review the installation
of any pit prior to installation to ensure that it has sufficient airflow
characteristics and is approved by the facility’s design engineer to
avoid the risk of an accident.

• A water flow switch must be installed in the horizontal piping of the supply water line (evaporator outlet) to prevent evaporator
freezing under low or no flow conditions. The flow switch can be ordered as a factory-installed option, as a field-installed kit, or can
be supplied and installed in the field.
• Piping for units with brazed plate evaporators should have a drain and vent connection at the bottom of the bottom connection piping
and at the top of the top connection piping, respectively, (see Figure 4) These evaporators do not have drain or vent connections due
to their construction. Purge air from the water system prior to unit start-up to provide adequate flow through the evaporator.
• A suitable support for piping, separate from the unit, to eliminate weight and stress on fittings and connections.
• An expansion tank and regulating valve to maintain water pressure.
• Suitable mechanical connections. All evaporators have.
• OGS type grooved water connections (adhering to AWWA C606) optionally with flanges. PVC piping should not be used.
! WARNING !
Polyolester oil, commonly known as POE oil, is a synthetic oil used in many refrigeration systems and is present in this Clima Flex
product. POE oil, if it ever comes in contact with PVC/CPVC, will coat the inside wall of the PVC/CPVC pipe causing environmental
stress fractures. Although there is no PVC/CPVC pipe in this product, keep this in mind when selecting piping materials for your
application as system failure and property damage could occur. Consult the pipe manufacturer’s recommendations to determine
suitable pipe applications.

Figure 4. Typical piping of a welded plate evaporator.
It is recommended that the field-installed water piping for the chiller include:
• Temperature sensors at evaporator inlet and outlet connections.
• Water pressure gauge connection taps and pressure gauges on evaporator inlet and outlet connections to measure water pressure
drop.
• Shut-off valves to isolate the unit from piping during unit maintenance.
• Minimum elevation changes and bends to minimize pressure drop.
• Vibration eliminators on supply and return water lines to reduce transmissions to the building.
• Thorough flushing of system water piping prior to making connections to the unit evaporator.
• Insulation of the piping, including a vapor barrier, helps prevent condensation and reduces heat loss.

WATER FLOW LIMITATIONS
Constant evaporator flow
Maximum flow rate and pressure drop are based on a 6°F temperature drop. Flow rates above the maximum values will result in
unacceptable pressure drops and may cause excessive erosion, which could lead to failure.
The minimum flow rate and pressure drop are based on a full load evaporator temperature drop of 16°F. Evaporator flow rates below
the minimum values may result in laminar flow leading to low pressure alarms, fouling and poor temperature control (See pressure drop
on page 16).
Variable evaporator flow
Reducing evaporator flow rate in proportion to load can reduce system energy consumption. The rate of flow change should be a
maximum of 10 percent of the flow per minute. For example, if the maximum design flow rate is 200 gpm and is to be reduced to a flow
rate of 140 gpm, the flow change is 60 gpm.

System water considerations
All chilled water systems need adequate time to recognize a load
change, respond to the change and stabilize to avoid undesirable
compressor short cycling or loss of temperature control.
In air conditioning systems, the potential for short cycling often
occurs when the building load drops below the minimum capacity
of the chiller plant or in tightly coupled systems with very small
water volumes. Some of the aspects that the designer should
consider when studying water volume are the minimum cooling
load, the minimum capacity of the chiller plant during the low-load
period, and the desired cycle time for the compressors. Assuming
there are no sudden loads and the chiller plant has a reasonable
drawdown, the rule of thumb of “water volume in gallons equals
two to three times the chilled water flow rate in gpm” is often used.
A storage tank may have to be added to the system to achieve the
recommended volume.
The quality of water supplied by the owner/occupant/operator/
user to a cooling system should minimize corrosion, scale
buildup, erosion, and biological growth to achieve optimum
efficiency of HVAC equipment without creating a hazard to
operating personnel or the environment. Filters should be used to
protect cooling systems from waterborne debris. Clima Flex is not
responsible for damage caused by waterborne debris or damage
to chiller heat exchangers due to improper water treatment.
Water systems should be cleaned and flushed prior to chiller
installation. Testing and water treatment should be verified during
initial chiller installation/commissioning and should be maintained
on an ongoing basis by water treatment professionals.
! CAUTION !
Improper use of detergents, chemicals and additives in the
cooling system water can adversely affect the performance
of the chiller and potentially result in repair costs not covered
under warranty. Any decision to use these products is at
the discretion of the owner/occupant/operator/user, and the
owner/occupant/operator/user assumes full responsibility for
any damage that may occur due to their use.
Evaporator freeze protection
Evaporator freezing can be a problem in the application of air-
cooled water chillers in sub-zero temperature areas. To protect
against freezing, the evaporator comes with insulation.
Although the evaporator is equipped with freeze protection, it does
not protect the water piping external to the unit or the evaporator
itself if there is a power failure or heater burnout, or if the chiller
cannot control the chilled water pumps.

It is important that the chilled water pumps are connected to and
controlled by the chiller’s microprocessor. The controller will
activate the pump whenever at least one chiller circuit is enabled
for operation.
This helps ensure proper start-up sequence of the unit. The
pump will also turn on when the water temperature is below the
freeze set point for longer than the specified time to help prevent
evaporator freeze-up. Connection points are shown in the field
wiring diagram beginning on page 34+.
! CAUTION !
Adding glycol or draining the system is the recommended
method of freeze protection. If the chiller does not have
the ability to control the pumps and the water system is not
drained or does not have adequate glycol at subfreezing
temperatures, catastrophic evaporator failure can occur.
If the chiller is not allowed to control the pump, the following
problems may occur:
1. If the chiller attempts to start without first starting the pump,
the chiller will lock up with the no flow alarm and require a
manual restart.
2. If the chiller evaporator water temperature drops below the
“freezing set point”, the chiller will attempt to start the water
pumps to prevent evaporator freezing.
3. If the chiller does not have the ability to start the pumps, the
chiller will alarm for lack of water flow.
4. If the chiller does not have the ability to control the pumps
and the water system must not be drained in freezing tem-
peratures or contain glycol, the chiller may be subject to cata-
strophic evaporator failure due to freezing.
FLOW SWITCH
All chillers require a chilled water flow switch to verify that there
is adequate water flow through the evaporator and to shut down
the unit if necessary to prevent evaporator freeze-up under low or
no flow conditions.
A factory-installed thermal dispersion flow switch will be installed
on packaged models. On remote evaporator models, the flow
switch can be supplied separately in the field, or optionally
shipped loose for field installation. Terminals for field mounting
Ten percent of 200 gpm equals a change of 20 gpm per minute,
or a minimum of three minutes to go from the maximum flow to
the desired flow.
If the flow rate falls below the minimum allowable, large reductions
in heat transfer can occur. If the flow rate exceeds the maximum,
excessive pressure drop and tube erosion can occur.
Use one of the following recommendations for additional freeze
protection:
1. If the unit will not operate during the winter, drain the evapora-
tor and chilled water lines and flush them with glycol.
2. Add a glycol solution to the cold water system. Breakage pro-
tection should be approximately 10°F below the minimum de-
sign ambient temperature.
3. Insulate exposed piping.
4. Add thermostatically controlled heat by wrapping lines with
heat tape.
5. When glycol is added to the water system for freeze protec-
tion, the refrigerant suction pressure will be lower, the cooling
performance will be lower, and the water side pressure drop
will be higher.

GLYCOL SOLUTIONS
The use of glycol can affect system performance depending on
its concentration and should be taken into account during initial
system design. When glycol is added to the chilled water system
to protect against freezing, it should be noted that the refrigerant
suction pressure will be lower, the cooling performance will
be lower and the water side pressure drop will be higher. The
reduction in performance depends on the glycol concentration
and temperature. Test the coolant with a clean and accurate
glycol refractometer to determine the freezing point.
! CAUTION !
The installed glycol level must match the nominal glycol
percentage indicated on the submitted chiller technical data
sheet. Failure to meet the nominal glycol percentage may
result in damage to the unit and loss of unit warranty.
! CAUTION !
Do not use automotive grade antifreeze. Industrial grade
glycols should be used. Automotive antifreeze contains in-
hibitors that will cause plaque formation on the cooler evapo-
rator copper tubes. The type and handling of the glycol used
should be consistent with local codes.
and wiring of the water flow switch are provided in the unit control
center.
Wire from the Y and R terminals on the switch to the terminals on
the unit control panel shown in the field wiring diagrams, page 19
through page 22. Mount the flow switch on the outlet water line
to shut off the unit when water flow is interrupted. A flow switch
is an equipment protection control and should never be used to
cycle the unit.
Installation should be in accordance with the manufacturer’s
instructions included with the switch. Flow switches should be
calibrated to shut the unit off when operating below the minimum
flow rate.
There is also a set of paddle switch contacts on the switch that
can be used for an indicator light or alarm to indicate when a
“no flow” condition exists. Protect any flow switch that is installed
outdoors from freezing. It is not recommended that differential
pressure switches be installed outdoors. They may freeze and not
indicate a no-flow condition.

ELECTRICAL CONNECTION
CLIC STAND ALONE units can be ordered with standard multi-point power connections or with optional single-point connections and
various disconnect and circuit breaker options. Wiring inside the unit is sized in accordance with the NEC®.
The required field wiring varies depending on the configuration of the unit. Refer to page 19-22 for wiring diagram information. Voltage
limitations are:
1. Within 10 percent of nameplate rating.
2. Voltage unbalance must not exceed 2 percent. Since a voltage unbalance of 2% can cause a current unbalance of 6 to 10 times
the voltage unbalance per NEMA MG-1, it is important that phase-to-phase unbalance be kept to a minimum.
! DANGER !
Qualified and licensed electricians must perform wiring. There is an electrical shock hazard that can cause serious injury or death.
! DANGER !
LOCK OUT / DISCONNECT all power sources before starting, pressurizing, depressurizing or shutting down the chiller. Disconnect
electrical power before servicing equipment, including condenser fan motors or compressors. More than one disconnect may be
required to deenergize the unit. Failure to comply with this warning can result in serious injury or death. Be sure to read and under-
stand the installation, operating and service instructions in this manual.
Chiller electrical wiring connections may be made with either copper or aluminum wiring, provided the size and number of wires match
the chiller terminals. All wiring must be in accordance with applicable local and national codes, including NECA/AA 10402012 for
installation of aluminum wiring in buildings (ANSI).
Wiring inside the unit is sized in accordance with the NEC®. Refer to the unit nameplate and unit selection report for correct electrical
ratings.
1. The control transformer is supplied and no separate 115V power is required. For single and multipoint power connections, the con-
trol transformer is on circuit #1 with control power wired from there to circuit #2. For multipoint power, disconnecting power from
circuit #1 disconnects the control power from the unit.
2. The size of the wiring supplied to the control panel shall be in accordance with the field wiring diagram.
3. The single point power supply requires a single disconnect to supply electrical power to the unit. This power supply must have a
fuse or use a circuit breaker.
4. All field wiring terminal range values listed in the unit selection report apply to 75°C cable per NEC.
5. It must be grounded per national and local electrical codes.
USE WITH ON-SITE GENERATORS
Switching from site mains to generator power and vice versa requires the chiller to be off or the power to be disconnected for more than
five seconds to avoid sending out-of-phase voltage to the chiller.
A properly installed and fully synchronized automatic transfer switch must be used to transfer power if the chiller is operating under load.
Generator sizing
! WARNING !
The generator should be sized by an electrical engineer familiar with generator applications.
! CAUTION !
Static discharge during handling of the circuit boards can cause damage to the components. Use an antistatic strap before perform-
ing any main tenance work. Never unplug cables, circuit board terminal blocks or plugs while the panel is powered.

! WARNING !
Electric shock danger. Improper handling of this equipment can cause personal injury or equipment damage. This equipment must
be properly grounded. Control panel connections and maintenance should be performed only by personnel knowledgeable in the
operation of the equipment being controlled. Disconnect electrical power before servicing equipment. Be sure to install a earth
leakage breaker. Failure to install a earth leakage breaker may result in electric shock or fire.
! WARNING !
When installing the earth leakage protector make sure that it is compatible with the inverter (resistant to high frequency electrical
noise) to avoid unnecessary opening of the earth leakage protector.ra.
! WARNING !
Stop the chiller before transferring power from the generator to the mains. Transferring power while the chiller is running can cause
serious damage to the chiller.
The procedure required to reconnect generator power to the mains is as follows:
1. Set the generator to always run five minutes longer than the unit start timer, which can be set from two to sixty minutes, while keeping
the chiller powered by the generator until the fully synchronized Automatic Transfer Switch properly delivers chiller power from the
site.
2. Set the transfer switch supplied with the generator to automatically shut down the chiller before the transfer is made. The automatic
shutdown function can be accomplished through a BAS interface or with the “remote on/off” wiring connection shown in the field
wiring diagrams. A start signal can be given at any time after the stop signal, as the three-minute start timer will be in effect.

Proper transfer of power from the standby generator to the grid is essential to prevent damage to the chiller and must be used to ensure
proper operation of the unit.
