Product Installation

Installation Environment

Ambient temperature: 10 °C~32 °C; ideal temperature: 18 °C~25 °C; air
conditioning system shall be used if necessary.

Ambient humidity: below 80% RH. The humidity shall be less than 60% Rh if the
maximum operating temperature is 32 °C.

Avoid large amounts of dust.

Avoid mechanical rocking or vibration.

Altitude of working position of biomedical freezer: lower than 2000m.

Input voltage: within 220V±10%.

The biomedical freezer is sensitive to ambient temperature. If installed in an
environment other than the above, the biomedical freezer cannot operate
normally. Please use it after improving the environment.

Do not install the biomedical freezer outdoors. Exposure to rain may cause an
electric leakage or electric shock.

Installation Site

It shall not be installed in a narrow and closed space. The door body of the room
where the biomedical freezer is placed shall not be smaller than or lower than
the biomedical freezer, or at least the normal access of the equipment shall be
ensured, so as to avoid maintenance di

翿

culties in the event of equipment failure

and causing damage to the stored items due to failure of repairing the equipment
in time.

The ground for installation must be solid and ﬂat, non-combustible and able to
withstand the weight of the equipment during operation.

Good ventilation, no direct sunlight.

Each refrigerator-freezer shall be provided with an independent power socket.
Please ensure that the power socket shall carry a current of ≥ 10A and the plug
shall be ﬁrmly connected to the socket. The power cord shall not be twisted or
pressed.

Check the working voltage before use. A voltage stabilizer suitable for the
equipment load shall be considered for use in areas with unstable voltage. The
voltage stabilizer power shall be more than 4000W to ensure that the input
voltage requirements in the installation environment are met.

The equipment shall be grounded securely. If the power cord socket is equipped
with a grounding wire, check that the grounding is good before use. If the socket
is not equipped with a grounding wire, be sure to have a professional engineer
install the grounding wire.

WARNING

Do not connect the grounding wire to a gas pipe, water pipe,
telephone line, or lightning rod when grounding the biomedical
freezer, otherwise it may cause an electric shock.

The power plug must be accessible after installation to facilitate
timely unplugging of the power cord in case of emergency. Do
not block the vent of the biomedical freezer.

Precautions for Use

When the biomedical freezer is running, the left and right rear sides of the biomedical
freezer may be heated, which is not a fault. In order to prevent condensation around
the biomedical freezer housing, the condensate pipe is installed.

Before putting items into the equipment, conﬁrm that the temperature in the
storage chamber has reached the set temperature, and then put the items in
batches. Do not put in items for more than 1/3 of the volume of the chamber at a
time to prevent its temperature from rising too much.

The equipment temperature display is the temperature at the temperature sensor
in the storage chamber. When the equipment is initially running, the displayed
temperature is somewhat diﬀerent from the actual temperature at the center of
the equipment. However, as the equipment enters a stable state, the displayed
temperature will gradually approach the actual temperature.

The equipment chamber is designed with a testing hole so that the test line
inside the chamber can be led out for test. After the testing line is pulled out,
it is necessary to plug the testing hole again with thermal insulation material,
otherwise the temperature in the biomedical freezer may not reach the set
temperature and cause condensation around the outside of the hole (applicable to
biomedical freezers with testing holes).

Please use diluted neutral cleaner to clean the equipment. Do not use brushes,
acid, gasoline, soap powder, polish or hot water to clean this equipment, otherwise
it may damage the painted surface and plastic rubber parts. Special care must be
taken not to use volatile solvents such as gasoline to wipe plastic and rubber parts.

When the biomedical freezer is not in use for a long period, cut oﬀ the power
supply and turn oﬀ the battery switch.

If the biomedical freezer is not started again for a long time, a low battery level
may occur. After the battery switch is placed at "ON", the battery can be charged,
and the biomedical freezer can run continuously for about one week to charge the
battery (applicable to models with batteries).

Please minimize the time of opening the door during each access to the items,
so as not to cause great ﬂuctuations in the temperature and humidity in the
biomedical freezer.

After the door is opened, the temperature in the biomedical freezer will rise
sharply in a short time, which is normal, and it will return to set temperature of
normal operation after the door is closed.

After the biomedical freezer has been running for a period of time, a layer of frost
is formed on the inner wall and evaporator of the biomedical freezer. If the frost
layer is too thick, it will aﬀect the thermal insulation eﬀect of the biomedical freezer
and increase the power consumption. Therefore, after the frost layer reaches 5
mm, the attached shovel shall be used to defrost.

Before defrosting, the frozen items in the biomedical freezer shall be taken out
and placed in an environment suitable for storage, so as not to damage the items
due to temperature rise in the biomedical freezer.

There are many refrigerating coils in the biomedical freezer. The frost from
the inner wall shall not be removed by sharp tools such as knife, ice chisel
or screwdriver. The inner wall shall not be scratched during defrosting, or the
biomedical freezer will fail.
