Legend
A = Altitude above sea level (m)
B = Atmospheric pressure (mbar)
C = Refrigeration capacity correction factor
D
= Power consumption correction factor
- The maximum operating altitude is 2000 metres above sea level
- If the unit is to be installed at an altitude of between 1000 and 2000 metres above sea level, contact manufacturer.

= Ambient Air Temperature (°C) (2)
A
= Ethylene glycol (%) (1)
B
= Propylene glycol (%) (1)
(1)
Minimum percentage of glycol to prevent the water circuit from freezing at the indicated ambient air temperature.
(2)
Ambient air temperature which exceeds unit operating limits.
Water circuits must also be protected in winter even if the unit is not being used.

Safety
The unit must be firmly secured to the ground.
The following instructions must be followed:
Never access electrical components without having
first closed the main switch and switched off the
power supply.
Never access electrical components without some
form of insulation. Never access electrical
components if water and/or moisture are present.
Always disconnect the power supply by closing the
main switch before carrying out any work on the
cooling fans and/or compressors. Failure to do so
may result in serious injury.
Sharp edges can cause injuries. Avoid direct
contact with components and wear suitable PPE.
Do not introduce solid objects into water pipes.
A mechanical filter must be fitted to the water pipe
connected to the heat exchanger inlet.
The unit is supplied with high pressure switches
and/or safety valves, that are installed on both the
high-pressure and low-pressure sides of the
refrigerant circuit:
pay attention.
It is absolutely forbidden to remove any protection
system covering moving parts.
In the event of a sudden stop, follow the instructions in
the
Control Panel Instruction Manual
which is part of
the documentation supplied with the unit.
We
strongly
recommend
that
installation
and
maintenance operations are be performed alone but
with other people present.
In the event of an accident or problem:
Keep calm
Press the alarm button, if present or close the main
switch
Move the injured person to a warm place far from
the unit and in place him or her in the recovery
position
Immediately contact any emergency personnel in
the building or the call the Emergency Services
Wait until emergency personnel arrive and do not
leave the injured person alone
Give all necessary information to the emergency
personnel.
