Installation
Due to safety and operating reasons, the cabinet must not be used
outdoors. The cabinet should be installed in a dry and suciently
ventilated area. To ensure ecient operation, the cabinet should not be
installed in direct sunlight or close to heat sources.
Avoid placement of the cabinet in a chloric/acidic environment due to
risk of corrosion.
Clean the cabinet with a mild soap solution prior to use.
If the cabinet has been laying down (e.g. during transport.).
The cabinet must stand up-right for 24 hours prior to being turned on.
Initial setup steps
Certain cabinets are shipped
with a protective lm that
should be removed prior to
putting the cabinet into service.

BIOBASIC MANUAL | 7
Cabinets equipped with legs
should be levelled as shown in the
illustrations to the left.
For cabinets equipped with
castors, the oor must be level
to ensure stable positioning and
safe use. When the cabinet is
positioned, the 2 front castors
should be locked.
Adjusting the base

8 | BIOBASIC MANUAL
Installation
Cabinets with drawers and/or glass door must be secured to a stable
vertical surface, ensuring that the cabinet can not tip over when the
drawers are drawn to the outermost position, or the door is open.
Brackets for securing the cabinet are included from the factory.
Find the instructions for the tilt bracket below.
The anti-tilt brackets must be tted when installing the cabinet,
ensuring that the users, surroundings and stored items are not
damaged.
Anti tilt bracket

BIOBASIC MANUAL | 9
Wall mounting
Wall mounting brackets can be supplied if specied. Allowing the
cabinet to be lifted from the oor. Find instructions on wall mounting
of a BIOBASIC 210 below, the same procedure applies for mounting 310
and 410.

10 | BIOBASIC MANUAL
Installation
There must be at least a 30mm gap between cabinets and/or walls.
A visual inspection of the cabinet must be conducted prior to putting
the cabinet into service. Check the cabinets structural integrity, that
door frames and doors don’t have deformities, gaskets seal properly
and the doors sit ush up against the door frame.

The illustration below shows the three connectors for the relay (e.g..
in connecting to CTS or other external monitoring systems). The three
connections, are respectively Common, NO (Normally Open) and NC
(Normally Closed).
The moment voltage is applied, the controller draws the relay, this
makes it possible for the controller to respond to both high and low
temperature alarms, door alarms and power failures. Find instructions
on setting the alarms in the controller settings section.

Installation
When setting up in an ordinary scenario that is not subject to
regulations for EN 60079-15 zone 2:
The appliance may be connected in accordance with applicable local
heavy current regulations.
Note that there are special regulations for products that are in
accordance with EN 60079-15 zone 2.
The appliance has been manufactured in accordance with EN 60079-
15: Electrical apparatus for explosive gas atmospheres - Part 15: Type
of protection “n”. Zone 2 is the applicable zone. If the appliance is to be
installed in a zone 2 environment, specialist personnel should perform
the installation, or be consulted beforehand, in order to ensure that
the appliance is installed in compliance with the guidelines currently
contained in the standard.
The cabinet is intended for connection to alternating current. The
connection values for voltage (V) and frequency (Hz) are given on the
type/number-plate.
The power cord from the mains is plugged in
the terminal box on the back of the cabinet.
The plug is then xated in place by the
hanger that is built into the terminal box.
Please note that the hanger should be tted
tightly around the plug, as shown.
Connecting to electricity

BIOBASIC MANUAL | 13
The appliance must be connected to the external power supply using a
suitable device which mechanically prevents the plug and socket from
being separated unintentionally. The connection must be labelled:
”DO NOT SEPARATE WHEN ENERGIZED” .
Fuses and similar must never be removed or replaced while the
appliance is connected to a power source. The electrical terminal box
must never be opened while the appliance is connected to a power
source. The compressor starting equipment must never be dismantled
while the appliance is connected to a power source. The LED lighting
must never be dismantled while the appliance is connected to a power
source. Whenever electrical components are dismantled or replaced,
the appliance must be moved to an area in which there is no risk of
ignition caused by the electrical components or gases contained in the
appliance. Never use the cabinet if the plug is damaged. The cabinet
should be examined by a Gram Commercial A/S authorised service
technician in such cases.
In both cases:
Use a three-wire plug, if the power outlet is intended for a three-wire
plug, the lead in green / yellow insulation should be connected to the
ground terminal. Power must be connected via a wall socket. The wall
socket should be easily accessible. All earthing requirements stipulated
by the local electricity authorities must be observed. The cabinet plug
and wall socket should then give correct earthing. If in doubt, contact
your local supplier or authorized electrician.
In case of technical diculties or breakdowns, always
contact authorized service personnel. Never dismantle the
terminal box or any other electrical component.

Start up
Turn On/O:
Press shortly to turn the cabinet on and press for 6 seconds to turn
the cabinet o.
Initiation procedure:
Readout of the software version and variant will occur shortly after
turning the cabinet on. The cabinet will then automatically start a
defrost-cycle, and terminate it again after a system check.
The cabinet is ready when the temperature is displayed.
The cabinet will always commence operation when initially connected
to a power supply. For instance after a power outage or when plugging
the cabinet in for the rst time.
Setpoint temperature adjustments:
Temperature adjustments are done by pressing for 3 seconds,
prompting the set point temperature. Adjust the set point temperature
by either pressing or . Conrm the settings by pressing .
Servicing:
Make sure the appliance is switched o at the socket before service is
performed on the cabinet. It is not sucient to switch o the cabinet on
the On/O button, as current will persist in some electrical parts of
the cabinet.
If fuses or similar are to be replaced, the appliance must be moved to a
no-risk area for safe replacement.
