R290 ICE MACHINE

Charging Volume

As R290 is highly flammable, its charging volume CANNOT be greater than 150g as
required by most governments and regions. This is equivalent to the charging
volume of about 10 lighters.

Special Parts

All electrical elements of the iBeeCool’s R290 ice machines (i.e. iBC-129P,
iBC-219P, iBC-101B, iBC-289, iBC-350P, and iBC-500P), including compressor,
relay, switch and controller are

explosion-resistant parts

that passed tests and are

permitted to be used in equipment using flammable coolant. Electrical parts that are
not tested or may cause a fire or become an ignition source must be completely
sealed to avoid becoming a possible ignition source. For all the reasons above, the
parts of iBeeCool R290 ice machines can only be replaced with

original

accessories

only.
