Proper Handling and Installation
You might have acquired the best and most efficient equipment but an improper installation will cause low performance, greater electrical consumption, unusual noises and deterioration of its components.

Special care must be also given to the handling. Keep the condenser in an upright position to prevent damages to the compressor. On the other hand, sudden movements or blows might be the cause of welding cracks originating refrigerant leakage, vibration, instability, breakdown or noises in other components.

The main aspects to be considered in the installation are:

Supply ducts must be correctly sized and insulated. Due to lack of space, it is common that their sizes are inferior to the required which restricts the passage of cool air forcing the equipment to operate under inadequate conditions.


An easy, free and fast return of air must be present in every environment.


Supply and return refrigerant pipes must have the proper diameter, length and material. They should also contain all their line accessories as drying filters, liquid viewers, etc. and be properly insulated to avoid liquid refrigerant or lack of oil in the compressor.


The supports for the condenser and evaporator unit must be installed in the upright position, that is, at zero degrees of the horizon. Also, they must be firm, capable of resisting their weight and provided with neoprene rubbers to absorb vibration. The aforesaid will help to prolong the useful life of the vital components such as compressors and motors and the entire equipment as a whole.

Filters must be of good quality, cover the whole return area of the equipment and of an easy removal for their cleaning.

The electrical power supply, main breaker and wiring of the place where the equipment is to be installed, must be checked with the purpose of making sure that there is enough capacity to resist the electrical load to be added. Likewise, electrical materials to be used in the installation must fulfill the specifications of the National Electrical Code in order to prevent failures or damages to essential components.


The thermostat must be located in an area where it receives the returned air and thus obtain the actual temperature reading to prevent starts in short periods.

A small siphon must be set up in the drainage pipe to let the water easily flow out of the equipment.

There should be nearby electrical and water supplies as well as drains for its mantenance.
