Safety precautions for usage and maintenance
WARNING
• When there is something unusual (like burnt smell), cut o󰀨 the power supply at once and contact the
sales agent. The ongoing unusual condition would lead to malfunctions, electrocution or re hazards.
• When refrigerant leaks, take corrective measures to prevent oxygen depletion by increasing refrigerant
concentration.
• Do not use or place inammable or explosive substances near the unit.
• Do not do troubleshooting personally, as incorrect troubleshooting would lead to electrocution or re
hazards. Instead, please contact GREE after-sales service center.
• When the unit is charged with refrigerant, do not solder or cut any pipeline, ned heat exchanger, shell-
and-tube heat exchanger or other containers.
NOTE
• Do not let the unit out of the designed application range; otherwise it would cause the heat exchanging
tube cracking, refrigerant leakage or even explosion.
• Do not let the cold/heat source directly act on the stored foods, plants, animals, precision instruments,
and curiosities, otherwise their quality would be degraded.
• Only circulating water with satisfactory water qualify are allowed for the unit, as unsatisfactory water
quality would shorten the service life of the unit or even malfunctions.
• When the unit has been put into use for some time, check for security of the installation foundation.
Unstable foundation would lead to deformation or even safety accident.
• Once the unit is started up, stop it at least 6 minutes later, otherwise it would shorten the service life of
the unit. Never deliberately start or stop the unit frequently.
• Under subzero climatic conditions, pay attention to freeze protection. When the unit is out of use in
short time, do not cut o󰀨 the power supply, as freeze protection will not act normally. When the unit is out
of used in quite long time, add anti-freezing agent to water or drain the water system, otherwise it would
make the shell and tube crack and then leak.
DANGER
• Do not use the fuse out of the normal range or replace it with the electric wire, otherwise it would
damage the unit or lead to re hazards.
• Do not start or stop the unit directly by the power switch, as it would be likely to cause electrocution or
re hazards.
• Do not change settings of safety devices; otherwise it would lead to re hazards and explosion.
• Do not operate the unit with wet hands.
• Do not clean the unit without cutting o󰀨 the power supply, as it would lead to electrocution or personal
injury.
• Do not let children pull power lines or climb the unit to prevent of electrocution or other dangers.
• Do not touch high-temperature parts of the compressor and refrigerant lines, as it would lead to burns.
• Do not touch sharp edges and ns of the heat exchanger; otherwise it would lead to personal injury.
。
• Do not touch any moving part; otherwise it would lead to accidental injury.
• Do not stand on the unit or replace objects on it.
• Do not bend pipeline and retrot the unit, otherwise it would lead to refrigerant leakage, explosion, re
hazards or personal injury.
