Instructions on how to drain the cooling circuit
In order to drain the cooling circuit completely by means of type-approved devices, drain the refrigerant fluid from both the high and low-pressure sides and
in the liquid line. Use the load connections in every section of the circuit. In order to drain the refrigerant fluid completely all the circuit lines must be drained.
The fluid must not be discharged into the atmosphere as it causes pollution. It should be recovered in suitable cylinders and delivered to a company author-
ised for the collection.

Notes
Besides checking the various electrical devices, the electrical in-
sulation of all the cables and their correct tightening on the termi-
nal boards must be verified, paying special attention to the earth
connections.
This operation must be carried out by skilled personnel of author-
ised workshops, qualified to operate on this type of products.
Make sure the motors and fan blades are clean and that there are
no abnormal vibrations.
The motor must be kept clean with no traces of dust, filth, oil or
other impurities. These could cause it to overheat due to low heat
dissipation.
The bearings are usually watertight with permanent lubrication
and sized in order to last approximately 20.000 hours in standard
operational and environmental conditions.
This operation must be carried out by skilled personnel of author-
ised workshops, qualified to operate on this type of products.
If the unit is idle during winter months, it must be emptied. In alter-
