1. GENERAL DESCRIPTION
GENERAL DESCRIPTION
CLIMAFLEX chiller units are built with control and design in
mind, assembled with technically specialized control
software. Some of our features are in house production of all
piping and wiring, scroll type compressors, new generation
evaporators, air cooled condensers, optional hydraulic
components, and several safety and security protections.
Our units are ecofriendly and operate with R-410A
refrigerant.
ELECTRICAL COMPONENTS
All units are equipped with a control panel, security anti-
theft devices, internal and external overheating protection,
compressor drive protection, flow protection, freezing
protection and electrical failure protection. The control
panel has LED operation indicating lights.
EQUIPMENT
Fully Factory assembled, and individually run tested with all
required piping, wiring, and controls for operation.
HYDRAULIC COMPONENTS (OPTIONAL)
Water Pump
The drive in the water pump is TEFC (Totally Enclosed
Fan Cooled) and has anti-corrosive coating on the
housing.
MODULE
Steel base, anti-corrosive painted steel panels. Easy Access
for maintenance without compromising the unit´s stability.
CONTROL

1.1 ADVANTAGES OF CLIV SERIES CHILLER UNITS
NEW CLIV MODELS
EFFICIENCY
CLIMAFLEX water chillers are designed to comply with all requirements on all commercial projects. Air
cooled CLIV-CLIMAFLEX units may be applied in many ways; the units can be installed as stand alone or
in any number combination to get the exact required capacity for the project demands. The operation
allows modulating in accordance with the building thermal load variations, and achieving the desired
temperature in a precise and fast manner with high efficiency and minimum energy consumption.
CLIV CLIMAFLEX unit capacity ranges from 3 to 5 Tons.
OPERATION
CLIV CLIMAFLEX units have reduced vibration levels making them virtually silent. The overall design
allows for easy, fast, and low price installation.
QUALITY
Each unit is carefully manufactured and individually tested under strict international standards. CLIV
CLIMAFLEX units have state of the art components that offer a high quality product.
ENVIRONMENTALLY FRIENDLY
CLIMAFLEX units use R-410A refrigerant to reduce operating costs, and contribute to a significant
reduction of CO2 emissions. We are ecofriendly and strive to make green quality products.

8. INSTALATION and STARTUP
8.1 INSTALATION
/!\ WARNING /!\
To keep warranty this unit must be
installed by trained personnel with
expertise on water chillers
installation.
Some of the voltages on the unit may
be dangerous, before servicing it is
recommended to totally de-energize
the unit.
LOCATION
CLIV Units are designed to be installed in interiors. It is
necessary that the unit has air venting, and a free air intake
(see Fig 1) to allow for good air circulation and allow access
for maintenance.
For fully functioning, CLIV units only require the connection
with the hydraulic local net and power supply connection in
accordance with technical data sheet.
Note: For optimal operation machinery room should be at a
maximum temperature of 95 °F (35 °C)

1.1. INSTALATION
The following items must be checked before the unit´s startup.
UNIT MODEL:
SERIAL NUMBER:
/!\ WARNING /!\ The following procedures are to be considered by
the installer; their personnel must be qualified, and certified to
perform installation in order to comply all specifications and good
practices to assure the correct unit´s operation.
1.- PHYSICAL INSPECTION (BEFORE ELECTRICAL CONECTION)
Check unit for possible transportation or handling damage.
Visual check for refrigerant leaks.
Only Open unit to install system piping. Do not remove connection´s protection until hydraulic
circuit is to be closed.
Check for foreign objects in fan discharge.
Check pulley alignment, and band tension.
Check that air intake is not obstructed, and has the required space suggested on Fig. 1
2.- HYDRAULIC CIRCUIT INSPECTION
Water connections are NPT type inner thread (to identify the connection diameter, see unit’s data
sheet). The installation of a water filter is necessary on all hydraulic circuits in order to avoid solid
particles in it, which must be installed on the return side of the circuit, and cleaned once the system´s
initial charge is finished.
Check water filter to be clean.
Verify that all service valves are open.
Check for adequate makeup water supply.
Verify that all piping is filled with water and air has been vented out.
Check Thermometers.
Check Manometers.
Note: Accessories such as Thermometers, manometers, measuring ports, etc. are recommended but
not necessary for the unit´s operation.
/!\ WARNING /!\ If hydraulic circuit contains air, it may compromise the units operation.

1.2.1. ELECTRICAL SUPPLY INSPECTION
The electrical pipes are nipple NPT threaded conduit (1” inch diameter on all models) the units require 3
phase grounded electrical power.
Verify that the thermo-magnetic switch is of correct capacity for the unit.
Check that all electrical connections are tight.
Check for false contacts on ground, and all wiring.
Check internal connections for control and power.
Measure voltage on all lines, and ground, neutral, and TF line.
Check for overload protection on motors to be in position to design requirements, and
on automatic mode.
Check voltage monitor control (*Motor Saver), to be adjusted to supply the correct
power voltage for the unit.
Note: The unit´s control panel has a ventilation duct, and it must not be obstructed in any manner.
*The unbalance percentage of electrical supply should
be calculated with the following formula and adjusted
on the UNBALANCE TRIP knob.
UNBALANCE PORCENTAGE = [(MAXIM AVERAGE
DEVIATION)/(AVERAGE)]X[100]
Note: CLIMA-FLEX units are previously factory
adjusted however the electrical supply may vary on
each installation, and due to this unbalance must be
adjusted before startup in order to protect all the unit´s
motors and electrical components.

1.2.2. CONTROL PANEL INSPECTION
Check the control panel to ensure that it is free of foreign objects.
Energize the unit with 3 phase electrical power. Phase unbalance must less than 2% of
average.
Cycle each fan to assure rotation is correct
Cycle water pump (if applicable) to ensure that it is correctly energized.
/!\ WARNING /!\
CLIV units are equipped with scroll compressors which must rotate freely or mayor damage to the
compressor may happen. Check rotation previously to start.
1.3. STARTUP
After finishing the inspection of the previous installation points and making sure all the unit’s items are
correct the unit may be started.
1. UNIT CONTROL
Set the UNIT CONTROL switch on the ON position (Fig 2) to energize the control panel with 24 Volts.
After energizing the controller, wait five minutes for the unit to be on line and ready.
2. ON/OFF
Operation sequence will initiate by checking all security pre-programed points on the unit. If all
required conditions are OK the unit will be ready to initiate operation.
To start operation set the ON/OFF switch (Fig 2) to the ON position.
After six seconds the controller will command the start of the water pump.
If water flow is detected on the pipes, the internal sequence of the unit will begin.

3. COMPRESSORS
Set the APG1 switch, 24V (Fig. 2) to the ON position afterwards set the APG2 switch also to the ON
position, this will enable the compressors start cycle.
Note: The APG4 switch (Fig. 3) selects the unit´s operating mode, whether is it cooling only or heat
pump. If you wish to operate the unit as heat pump turn this switch to ON.
