1.1. CLIMA-FLEX UNITS ADVANTAGES

Clima-Flex CLIC units leave the factory as a kit ready to be installed outdoors at both the floor or
ceiling level. The use of air-cooled condensers eliminates the cost and the need to install and
maintain a cooling tower.

The  CLIC  family  has  a  smaller  footprint  and  lower  weight  than  the  competition.  Installation  of  the
cold  water  pipes  is  also  easier.  All  CLIC  units  leave  the  factory  with  the  water  quick  connect
connections  installed  and  ready  to  be  used.  Grooved  or  threaded  water  connections  are  also
available  for  easy  installation.  Optionally  the  units  may  require  a  pumping  module;  this  module
reduces installation time and space dedicated to a pump room.

All Clima-Flex CLIC units have been tested on the factory to ensure proper operation.

Clima-Flex CLIC units are designed to require less service calls. The scroll compressors can last
hundreds of thousands of hours of continuous operation in different applications and conditions.
The Adsil special anticorrosive coating ensures longer life and better performance.

The components and control sequences used in our units are designed to keep CLIC Clima-Flex
units always running, safety and health monitoring systems optimize performance on the go.

The units are designed to meet the AHRI Standard 55/590 and the UL-1995 standard security.

5. INSTALLATION AND UNIT STARTUP

WARNING /!

LOCATION

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.

CLIC Units

are designed to be installed outdoors.

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,

CLIC

units only require the

connection  with  the  hydraulic  local  net  and  power
supply  connection  in  accordance  with  technical
data sheet.

Note:

For optimal operation if the

CLIC

unit is

installed in a machinery room, it should be at a
maximum temperature of 95 °F (35 °C)

● 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). 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.

5.1.1. ELECTRICAL SUPPLY INSPECTION

The electrical piping is

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.
