The table below defines the limits and conditions for the application and operation of the
units.
Table of Conditions and Limits for Application and Operation
Before starting up the unit, observe the above conditions and the following items:
•
Check that all of the electrical connections are securely connected;
•
Check that there are no leaks of refrigerant;
•
Confirm that the force discharge is compatible with the electrical specifications of the unit;
•
Ensure that the compressors can move freely above the vibration insulators of the outdoor
unit;
•
Ensure that all of the service valves are in the correct operating position (open);
•
Ensure that area around the outdoor unit (condensing unit) is free of any obstructions the
air intake and discharge;
•
Confirm that perfect drainage occurs and that the drainage hose is not blocked.
The fan motors of the units are lubricated in the factory. DO NOT lubricate them again
when installing the units. Before starting up the motor, verify that the propeller or turbine
of the fan is not loose.
In outdoor unit assembled exclusively with Scroll-type compressors, the noise of
these compressors must be heard after start-up. If this noise is high and the
pressures are the same after start-up, invert the two feed phases! This procedure is
compulsory and failure to perform it will invalidate the warranty of the equipment.
