• It is advisable to examine carefully the unit upon receipt.
• Inspect equipment received for damage or missing element. If units are damaged or shipment is
incomplete, immediately file the claim with the transport company. (Within the first 48h)
• Check if unit nameplate voltage is correct and agrees with local power supply.
• In case of detecting any damage or anomaly it is recommended to contact our customer support.
If the unit is to be stored before installation, several precautions must be kept to avoid any damages,
corrosion or any other type of deterioration:
• Do not store the unit in locations with temperatures over 50ºC and preferably without exposure to direct
sunlight.
• Minimum storage temperature: -10ºC
• Maximum humidity: 90%
Moreover it is recommended:
- Move it carefully
- Avoid placing other objects on the unit (Unless this is done within the overlay limits indicated in the
packaging)
- Avoid placing the unit with heat shrink protection under the sun, as the pressure of the circuits might
assume values that could lead to activation of the safety valves
• Before moving the unit be sure that all units panels are well fixed.
• Raise and set down the equipment carefully.
• Never tilt the unit more than 15 degrees during transportation (Fig. 2).
• When lifting the unit ensure that it is balanced and steady, keep in mind that the heaviest part is where
the compressor is installed.
• Always transport unit to installation place in original packaging.

• If is necessary to add or recuperate refrigerant 410A always do it in LIQUID phase. Supplying refrigerant
in gas or vapor form, by mistake, will result in wrong mixture conditions.
• Due to its high pressure and quick evaporation, refrigerant R410A cannot be kept in liquid phase inside
charge cylinder because bubbles would form, altering the readings.
• The electronic scale is reinforced with a four support-point structure for the weight sensor of the
refrigerant bottle.
• In addition, it can also be used for any type of refrigerant’s charge. The refrigerant’s charge is carried out
opening and closing the valve manually.
• Immediately repair all refrigerant leaks.
• Never overcharge the system.
• Never use compressor as vacuum pump.
• If during operation will appear symptoms of refrigerant loss is necessary to make leak test. Leak
detectors usually employed with CFC and HCFC cannot be used with R410a, due to chlorine in its
composition. A leak detector for R134A may be used but the sensibility will be lower (when sensibility is 1
for R134A, it falls to 0,6 for R410A).
• To find small leaks, you will need a detector for HCF. Sensibility for R410A is approximately 23 grams
per year.
• If gas leak is detected is necessary to remove and recuperate complete refrigerant charge. Pressurize
system with dry nitrogen. If leakage has been not detected break a vacuum, dehydrate and charge with
refrigerant.
Compressors with R410A refrigerant use polyester synthetic oil. Each compressor’s manufacturer
recommends a specific type of oil for its products. The compressor or the system should not be left opened
to atmosphere more than 15 minutes. Synthetic lubricants are used as ester (POE, Polyol Ester) that have
a high solubility with R410A. Since these types of oils are very hygroscopic, more care should be taken
rather than with the conventional ones. Furthermore, when these synthetic oils are mixed with minerals or
alkylbenzene, they deteriorate producing capillary obstruction or failures in the compressor. Do not mix
them under any circumstance.
COMPRESSOR LUBRICANT
REFRIGERANT CHARGE
Never use oxygen to pressurize system or purge lines for leak test. Oxygen reacts
violently with oil, which can cause an explosion resulting in damage, personal injury
or death.
If it is necessary to make brazing operation, first fill the circuit with dry nitrogen.
Burning refrigerant 410A results in toxic gas emissions.

START UP
• Start up to be performed by qualified technical people.
• Make start-up check list and use similar check up for service and maintenance. Record chilled water inlet
and outlet temperatures and pressures, outdoor air temperature, volts and amps of each compressor and
fan motor, suction and discharge pressure of each compressor.
• Should remind that after four hours of system operation is necessary to clean air filters.
• Observe at least 3 cooling cycle operations.
• Due to the fact that the unit has frequency converters for compressors and fans, it’s essential that the
supply be at a minimum of 300 mA to prevent supply cuts caused by the differential switch.
LCX CONTROL
► START UP:
► SHUTDOWN:
•Check if all wires are well tightened.
•Check if all panels are firmly secured with screws.
•Verify if there is no refrigerant or oil leakage.
•Verify if unit is installed on level.
•Verify if there is enough space for service and maintenance.
• Check if drain holes in unit base are not blocked.
• Check if the cranckcase heater of each compressor has been energized at least 24 hours before unit start up.
• Check if air filters are clean and correctly mounted.
• Check all grills, air diffusers, air ducts and flexible connections.
• Be sure that electrical power source agrees with unit nameplate rating.
•Fans rotate in the right direction.
