Do not add or replace refrigerant other than the specified type. It may cause
product damage, burst and injury. If the supply cord is damaged, it must be
replaced by the manufacturer, its service agent or similar qualified persons
in order to avoid hazard.
The appliance shall be stored in a room without continuously operating
ignition sources (for example: open flames, an operating gas appliance or an
operating electric heater)
In cases that require mechanical ventilation, ventilation openings shall be
kept clear of obstruction.
Ventilate any enclosed areas when installing or testing the refrigeration
system. Escaped refrigerant gas, on contact with fire or heat, can produce
dangerously toxic gas.
