SAFETY PRECAUTIONS

Installation and maintenance of air conditioning equipment can be dangerous because the system is under pressure,

because some of its elements have high temperatures and include electrical components.

Only qualified and trained service staff should install, commission and carry out maintenance works. Unqualified staff

should only carry out basic tasks such as cleaning and replacement of filters, etc.

In every visit, all precautions should be taken into account: those recommended in the Installation, operation and

maintenance instructions, as well as the ones indicated in labels of the unit. Do not forget to strictly follow any other

safety codes.

Use safety glasses, work gloves and any other safety accessory necessary.

For brazing operations use a quenching cloth and have at close distance a fire extinguisher.

When repairing the unit, use only original spare parts and install them properly in the same position where old parts

were placed.

The equipment is designed to work with 100% recirculated air. For installations with external air supply, consult our

commercial department.

Do not install the unit in explosive atmosphere.

Before starting installation, service or maintenance, turn off the main power switch in

order to avoid electrical shock that may cause personal damages.

START-UP

Start-up should be performed by qualified technical people.

Use a start-up check list: record inlet and outlet temperaturesof the indoor coil, volts and amps of each compressor

and fan motor, suction and discharge pressure of each compressor.

Remember that after the first 4 hours of operation, it is necessary to clean the filters.

Monitor at least 3 cooling cycle operations.

Due to the unit has frequency converters for compressor and fans, it’s essential that the differential supply be at

minimum 300 mA to prevent supply cuts caused by the differential switch.

Check the following points:

Electrical connections are well tightened.

Panels are firmly secured with screws.

There are no oil or refrigerant leaks.

The unit is correctly leveled.

There is enough space for service and maintenance.

Drainage is not blocked.

If outdoor temperature is under 25ºC, verify the crankcase heater of the compressor.

Air filters are clean and correctly mounted.

Grilles, air diffusers, air ducts and flexible connections are in good condition.
