CAUTION
Keep the biomedical freezer clear of obstruction around it to ensure smooth
ventilation.
When it needs to restart the biomedical freezer after the biomedical freezer
is unplugged or the power to the biomedical freezer is interrupted, check the
settings of the biomedical freezer. Changes in settings may deteriorate the
stored items.
If the biomedical freezer is unplugged or the power to the biomedical freezer
is interrupted, do not restart the biomedical freezer for at least 5 minutes to
avoid damage to the compressor or system.
The filter screen shall be checked in time and cleaned. Dust-laden filter
screens can cause temperature rise or failure in the biomedical freezer.
If the power plug has dust, it needs to be cleaned in time. Improper
connection or plug filled with dust may cause heating or ignition.
After the power is cut off or the power switch is off, the setpoint shall be
checked when the power switch is restarted; otherwise, the stored items may
be damaged due to setting change.
Wear gloves during maintenance to avoid personal injuries caused by
touching sharp edges or corners.
The stored items shall not be contacted directly by hand. Direct contact
with the frozen items or the inner wall of the biomedical freezer may cause
frostbite.
Hold the handle to close the chamber door, so that the door does not pinch
fingers.
Tilt the biomedical freezer for 30° when handling or moving it.
Be careful not to trip over the biomedical freezer when handling the
biomedical freezer, so as to prevent damage to the biomedical freezer or
personnel injuries.
Do not use door handles to lift or carry equipment to prevent damage to the
biomedical freezer or personnel injuries.
Do not damage the refrigeration circuit.
Do not use electrical appliances inside the storage compartment of the
biomedical freezer, unless they are of the type recommended by the
manufacturer.
Never store corrosive substances such as acids or alkalis in the biomedical
freezer. Otherwise, these substances may cause damage to internal
components or electrical parts of the biomedical freezer.
Never store flammable, explosive, or volatile substances in the biomedical
freezer or use flammable sprays near the biomedical freezer, otherwise it
may cause an explosion or fire.
Do not leave the plastic packing bags in a place where they can be reached
by small children as this may result in suffocation accidents.
Do not climb on the biomedical freezer or put any objects on the biomedical
freezer, otherwise the biomedical freezer may fall and cause injuries or cause
damage to the biomedical freezer.
Do not use the biomedical freezer outdoors. Exposure to rain may cause an
electric leakage or electric shock.
Do not place the biomedical freezer in a humid location or a place where
the biomedical freezer is easy to be splashed with water. Otherwise, electric
leakage or electric shock will be caused due to degradation of insulation.
Do not pour water directly onto the biomedical freezer, otherwise it may
cause an electric shock or a short circuit.
Never disassemble, repair, or modify the biomedical freezer yourself.
Otherwise, it may cause fire or personal injury due to improper operation.
Do not connect the grounding wire to a gas pipe, power supply pipe,
telephone line, or lightning rod when grounding the biomedical freezer. The
above grounding may cause electric shock or other hazards.
Do not touch any electrical parts such as the power plug or operate any
switch with a wet hand, otherwise, it may cause an electric shock.
Do not put water containers or heavy objects on the biomedical freezer.
Falling objects may cause personal injuries, and spilled water may cause
degradation of insulation, resulting in an electric leakage or electric shock.
Never insert metal objects such as iron nails and wires into any vent, gap,
or air outlet on the biomedical freezer. This may cause electric shocks or
injuries by accidental contact of these objects with moving parts.
It is not allowed to tie, drag, pull, wind and bind the power cord, or damage
the power cord plug. Damaged power cords or plugs may cause fire or
electric shock.
The power cord with a loose plug is not allowed, because it may cause fire or
electric shock.
It is not allowed to put glass bottles or canned items in the biomedical
freezer, which may be frozen and cracked, causing injury to personnel.
