Important Safety Instructions
Warning
The manual is retained for the entire service life of the machine.
The user reads the manually carefully before carrying out any operations on the machine.
The machine is a piece of professional equipment for use in industry, trades, and other professions, and it is not
intended for sale to the general public.
The machine is used exclusively for the purpose for which it is intended; incorrect use of the machine shall release the
manufacturer any liability.
This manual has been prepared to enable the end-user to carry out only the operation that can be made with the panels
closed. Any operation that require the opening of doors or equipment panels must be carried out only by qualified personnel.
Each machine is equipped with an Electric Insulation device which allows the operator to work in condition of safety. Switch
off the machine with this electric insulation device before any maintenance operation to eliminate risks remaining (electric
shocks, burns, automatic restarting, moving parts and remote control).
The panel key supplied with the unit must be kept by person responsible for maintenance.
For identification of the unit (model and serial no.) in case of the necessity for assistance or spare parts, locate the
identification label on the outside of the unit.
Potential hazards
The protective covers can be removed only after the electric power has been cut off by opening the main switch.
A warning label on the front and back panels reminds that:
The machine restarts automatically.
The main switch must be opened before opening the internal compartments for any operation.
If the doors are opened immediately after the machine has been switched off, there might be some hazard related to:
Components still at high temperature
Electrical heaters
Compressor, outlet area and outlet piping (about 100°C)
Components still at low temperature Evaporator
Rotating elements Fan impellers, they might continue to rotate for a while by inertia
These residual risks are highlighted by warning labels on the machine.
Warning -
Risk of electric shock
Risk of electric shock. Can cause injury or death.
Disconnect local and remote power supplies before working within.
Before proceeding with installation, read all instructions, verify that all the parts are included and check the nameplate to be
sure the voltage matches available utility power.
The iCOM microprocessor does not isolate power from the unit, even in the ‘unit off’ mode.
Some internal components require and receive power even during the ‘unit off’ mode of iCOM control.
The factory-supplied optional disconnect switch is inside the unit. The line side of this switch contains live high-voltage.
The only way to ensure that there is NO voltage inside the unit is to install and open a remote disconnect switch. Refer to
unit electrical schematic.
Follow all local codes.
Warning -
Risk of explosive discharge from high-pressure refrigerant
Risk of explosive discharge from high-pressure refrigerant. Can cause injury or death.
This unit contains fluids and gases under high pressure. Relieve pressure before working with piping.
