REFRIGERATOR 220V 70LTR 174642

Give the frequency as well as the voltage, because the code states 220 V only. One maker’s manual gives its operating voltage as 220–240 V at 50 Hz. It says to check that the rating plate matches the mains supply before connecting, and to use a socket with an efficient earth connection. Copy the ship’s voltage and frequency onto the order and ask for the rating plate to match.^[1]

Ask for the climate class. It is shown on the rating plate and gives the room temperatures the appliance is built for: SN +10 to +32 °C, N +16 to +32 °C, ST +16 to +38 °C and T +16 to +43 °C. An SN-T appliance can run from +10 to +43 °C. The maker advises running an appliance within its climate class. For a ship in the tropics, or a hot space, ask for class T or SN-T.^[2]

Give the space it will stand in. Makers set clearances for air flow: the manual above asks for at least 150 mm clear above the appliance and keeps it at least 50 cm from gas cookers and heaters. Check the manual of the model offered, measure the recess, and give the outside dimensions, the door hinge side and whether it must be built in.^[1]

Ask which refrigerant the offered model uses. The same manual says R600a is environmentally friendly but explosive. If the cooling circuit is damaged and leaks, move the appliance away from open flames and heat sources and ventilate the room for a few minutes.^[1]

MARPOL Annex VI regulation 12 prohibits installations containing HCFCs on ships built on or after 1 January 2020. On older ships it prohibits them for equipment delivered on or after that date. Do not accept an HCFC fridge. A ship with rechargeable systems containing ozone-depleting substances keeps an ODS Record Book. One is not required for ODS held in permanently sealed systems with no refrigerant charging connections or potentially removable components containing ozone-depleting substances.^[3]
