9.7 CHARGING THE COOLING CIRCUIT
9.8 PRECAUTIONS
WARNING!
This equipment is exclusively meant for professionally prepared operators that know the fundamentals
of cooling, cooling systems, cooling gasses and the possible damages that pressured equipment may
cause.
The compressor must exclusively operate with refrigerants indicated by the manufacturer. Oxygen must
never be allowed to enter the inside of the compressor. Do not start-up the compressor when there are
signicant vacuum conditions inside of it.
The units are designed to operate with R410a refrigerant. Do not dispose of R410a refrigerant as house-
hold waste as it is a uorinated greenhouse gas subject to the Kyoto Protocol, with a Global Warming Po-
tential (GWP
100
) of 2088. The refrigerant must be disposed of in accordance with the legislation in force
in the country where the units are installed.
Do not tamper or modify the calibration of the safety and control systems. It is recommended to wear
suitable protection such as glasses and gloves; some unit components can cause physical injuries to the
operator.
9.8.1 CALCULATION FOR THE QUANTITY OF REFRIGERANT IN THE CIRCUIT
WARNING!
The weights set forth in the tables are theoretical and may change when there are accesso-
ries and special congurations!
Refrigerant charging must be carried out as shown in the subsequent chapters!
The indicative quantity of refrigerant in the circuit is determined by the amount of refrigerant contained in each single ele-
ment of the circuit, according to the following formulas:
1) Refrigerant content of the units with remote condenser:
TOTAL REFRIGERANT CONTENT (kg) = UNIT CONTENT (kg) + ACCESSORY CONTENT (kg)+ SUP-
PLY PIPE CONTENT (kg) + LIQUID PIPE CONTENT (kg) + REMOTE CONDENSER CONTENT (kg)+
LT KIT CONTENT (kg)
2) Refrigerant content of the units with integrated water-cooled condenser:
TOTAL REFRIGERANT CONTENT (kg) = UNIT CONTENT (kg) + ACCESSORY CONTENT (kg) + WA-
TER-COOLED CONDENSER CONTENT (kg)
The values of the individual circuit elements are given in the following tables.
