EXTRAORDINARY MAINTENANCE
REFRIGERANT GAS CHARGING
Units are pre-charged with refrigerant gas R410a and adequately
tested in factory.
Therefore, under normal conditions, they do not require any
interventions by the manufacturer’s Support Technical Service as to
checking the refrigerant gas. However, small leaks may occur over
time through connections, from which refrigerant gas might come out,
thus discharging the circuit and causing abnormal operation of the
appliance.
In these cases, the refrigerant leaks must be located and
repaired, and the cooling circuit washed with nitrogen or suitable
products and then recharged according to this procedure:
– - Drain and dehydrate the whole cooling circuit with a vacuum
pump until reading about 10 Pa on the vacuum-meter;
Wait at least 5 minutes and make sure this value does not rise
again over 200 Pa..
- Connect the refrigerant gas bottle or a charging cylinder to the
liquid line tap..
– Charge the quantity of refrigerant gas (in liquid state) indicated
on the equipment’s rating plate.
– Always check the overheating and undercooling values which,
under the appliance rated operating conditions, must be included
between 6 and 10°C (OVERHEAT.) and max. 2 °C (UNDERCOOL.),
respectively.
After some hours of operation, make sure the flow indicator
shows “dry circuit” (dry – green).
Operating conditions other than the rated ones mat generate
significantly different values
The refrigerant gas must be only charged in liquid state .
The tightness test or the leak detection must be only
performed using refrigerant gas R410A, mixed with nitrogen if
necessary, checking with an adequate leak detector
Do not charge the cooling circuits with a refrigerant gas
different from R410C. Using a refrigerant gas other than
R410A may cause serious damages to the compressor
Do not use oxygen, acetylene or other flammable or
poisonous gases in the cooling circuit, because they can
cause explosions.
COMPRESSOR
The compressor is installed already filled with oil and sealed.
Therefore, it does not normally need special interventions by the
manufacturer’s Support Technical Service.
In case of failure, if the compressor can be repaired, only use
Mobil EAL ARCTIC 22 CC ester oil.
Do not use oils other than the one indicated. The use of other
oils may cause serious damages to the compressor .
CONTROL AND DISPLAY PARAMETERS
The unit control panel enables direct access to main control parameters and display of some typical system variables.
