1.4. For refrigeration equipment with the refrigerant R290
(propane)
According to the standard DIN EN 378-1 the refrigerant R290 (propane gas) is
assigned to the group of A3 refrigerants (flammable and explosive). Within the
limits of certain area, the refrigerant together with the air and respective ignition
power (source of ignition) can cause an exothermic reaction.
Ventilation openings at the front and rear sides of the unit have to be free. To avoid
disturbance of air circulation, make sure to maintain the minimum distance
between the bordering walls and other units. Otherwise, in the event of leakage of
the refrigeration system, a mixture of flammable gases and air can occur.
Cover the ventilation opening with a protective cover of the unit (accessory)
because they overlap. Otherwise, in the event of leakage of the refrigeration
system, a mixture of flammable gases and air can occur.
Do not damage the cooling coil of the unit: danger due to the escaped and
unexpectedly ignited mixture of gas and air.
Only the manufacturer
’
s approved electrical devices may be used for shelves of
food products.
The refrigeration system may be operated only by maintenance personnel
authorized and trained by FREOR LT to work with flammable and fluorinated
refrigerants.
Opening of the refrigerant circuit and pumping of the refrigerant are allowed only in
the well-ventilated rooms or outdoors. Only qualified maintenance personnel who
are trained to work with flammable and fluorinated refrigerants may perform the
work related to it.
When properly disposing the unit, pay the most attention that the flammable
refrigerant R290 (propane) and the thermal insulation material the polyurethane
foam would be disposed in a safe and environmentally-friendly manner.
1.5. Conditions for use and ambient temperature
The semi vertical has to be operated under suitable ambient conditions (climate
class 3):
•
Ambient tempe25°C
• Relative humidity 60%
• Front airflow rate up to 0.2 m/s
Higher temperature can affect operation of the semi vertical. Excess humidity
affects the dew point parameters. Strong front airflow can damage internal
circulation of the open semi vertical.
