greenhouses, etc.), or in places with other machines that generate a strong heat
source, in proximity of a sources of salt water or sulphurous water.
• DO NOT use gas, gasoline or other inflammable liquids near to the climate controller.
• The climate controller does not have a fan for the introduction of fresh outdoor air into
the room; ventilate by opening doors and windows.
• Always install circuit breaker and a dedicated power circuit.

0.5 - FUSE SPECIFICATIONS
• The appliance is equipped with a safety fuse, the specifications are printed on the board:
T20A/250 VAC (for unit with <24000 Btu/h)

• For units with R32 refrigerant, only use explosion proof ceramic fuses.
0.6 - CHECKS TO PERFORM BEFORE INSTALLATION
a. Checks at the area
Before starting to work on the systems containing inflammable refrigerants, safety checks are
necessary to reduce the risk of ignition to a minimum.
To repair a refrigeration system, the following precautions must be complied with before working
on the system.
b. Work procedure
The job must be performed according to a controlled procedure in a way to reduce the risk of
the presence of inflammable gas or vapour to a minimum during the performance of the job.
c. General work area
All maintenance personnel and those working in the local area, must be trained regarding the
job performed.
Do not work in tight spaces.
The area around the work area must be isolated.
Guarantee that the conditions inside the area are safe by verifying the inflammable material.
d. Check the presence of refrigerant
The area must be checked using a specific refrigerant detector before, during and after the
execution of the work so as to ensure that the technician is informed about the presence of
possibly flammable atmospheres.
Check the leak detector equipment used is suitable for use with inflammable refrigerants, i.e.
does not cause sparks, is suitably sealed or intrinsically safe.
e. Presence of extinguishers
Whenever work must be performed on the refrigeration system at high temperatures or on
relative components, a suitable fire-prevention system must be prepared.
Position CO2 or dry powder extinguishers in proximity of the loading area.
f. No source of ignition
No-one working in the refrigeration systems and exposed to contact with the piping that contains
or contained inflammable refrigerant, must use sources of ignition in order to prevent the risk
