samples to be re-introduced into the body.
If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Thank you for purchasing this GP Series cold storage equipment. Before
you first use this laboratory freezer please carry out the following actions:
• Check that the freezer has not been damaged in any way during
transportation.
• If any damage is found it must be reported to your local dealer
immediately.
• Ensure all packaging has been removed, including cardboard,
polystyrene and any tape used to hold shelves in place for
transportation.
• The freezer has been cleaned prior to dispatch; however, we advise that it
should be cleaned using lukewarm water containing a mild detergent
and a soft cloth.
• We recommend that the freezer should be left in an upright position for
24 hours prior to switching on.
• This equipment is not intended for use by persons (including children)

2 Positioning &
Safely Using your
GPSeries Freezer
CAUTION: To reduce the risk of the unit falling over, do not tip
beyond 10°.
• Make sure the equipment is placed in a dry, well ventilated site, away
from heat sources.
• The equipment must be placed on a level surface. If necessary, adjust the
feet on the product so the equipment remains level during operation.
• The equipment should have sufficient clearance around it to provide
adequate ventilation – 2'' at each side, 3'' at the rear and 1'' at the top.
• Before ANY maintenance activity, pull the plug out of the socket by
gripping the plug, DO NOT pull on the plug cord.
• DO NOT use extension cords.
• If the main power supply cord is damaged, it should be replaced by a
qualified service engineer.
• DO NOT attempt any repairs to the equipment yourself (apart from
those highlighted in the Maintenance and Service Section). Repairs
carried out by someone without the relevant training are putting their
personal safety at risk and will invalidate your warranty.

Transporting & Moving your GP Series Freezer
4 User Manual Thermo Fisher Scientific General Purpose Countertop Series
3 Transporting &
Moving your GP
Series Freezer
The freezer must always be moved in the vertical position. The cabinet must
not be tilted anymore than 10°. In the event that the cabinet is tilted more
than 10°, the power supply must not be connected until the equipment has
stood upright for at least 24 hours.
4 Energy Saving
Tips This equipment is cooled by energy-efficient R600a refrigerant. To keep
running costs as low as possible always:
• Position the equipment away from heat sources.
• Make sure the air can circulate freely around the equipment, don't block
ventilation grid.
• Ensure that products being stored are below room temperature before
placement inside the unit.
• Make sure the door is opened as little as possible while in use and closed
as quickly as possible to prevent unnecessary temperature fluctuations.

Important Information
Thermo Fisher Scientific General Purpose Countertop Series User Manual 5
5 Important
Information The freezer contains environment-friendly, non ozone depleting refrigerant
R600a. As R600a is a flammable gas, it is important to avoid damage to the
refrigeration circuit during transport and installation. If the refrigeration
circuit is damaged, avoid using a naked flame in the vicinity of the
equipment and connecting power to the equipment. Also make sure there is
good ventilation in the room. If you are in doubt, please contact your
supplier.
CAUTION: Keep ventilation openings, in the equipment enclosure or in
the built–in structure, clear of obstruction.
CAUTION: Do not use mechanical devices or other means to accelerate
the defrosting process, other than those recommended by the manufacturer.
WARNING: Do not damage the refrigerant circuit.
Note The power cord serves as the main disconnecting device.

Remote Alarm Contacts
Thermo Fisher Scientific General Purpose Countertop Series User Manual 13
10 Remote Alarm
Contacts All GP series laboratory freezers include remote alarm contacts and these
terminal contacts enable the user to connect to a remote control station;
these contacts can be found on the rear of the cabinet.
CAUTION: These contacts must only be accessed by a competent
electrician.
In order to use these contacts the following must be carried out:
1. The freezer MUST be disconnected from the power supply before
removing the terminal cover.
2. Unscrew the cover (Figure 1) on the right hand side of the rear of the
cabinet to expose the connectors (Figure 2).
3. Use the right hand outer positions that correspond to the left hand cable
positions for your connections using 0.75mm cable stripped to 0.6mm.
4. Depress the larger slot above the cable entrance on the right hand side
with a small electrical screwdriver. This allows the cable to be inserted
into the slot directly below.
WARNING: Note that the contacts supplied are voltage free. A voltage of
120VAC or 1 to 28VDC can be connected at the contacts. The maximum
load must not exceed 2A.
In a normal condition (i.e. no alarm) with the default menu settings, the
relay CLOSES the contact for the remote alarm facility. In an alarm
condition the relay OPENS the contact for the remote alarm facility. In the
case where the facility needs the contacts to close for an alarm condition,
refer to Section 8.6 for reversing the relay operation.
WARNING: For Alarm Remote Terminals any wiring connected to these
terminals shall be protected from mains voltage by reinforced or double
insulation.

Access Port
14 User Manual Thermo Fisher Scientific General Purpose Countertop Series
11 Access Port All GP freezers are provided with Access port that is located at the rear of the
unit.
IMPORTANT NOTE These units are intended for General Purpose Cold
storage. In case critical samples are stored, we recommend the use of a independent
temperature monitoring system which continuously monitors freezer performance.

Note The manufacturer recommends keeping the access port cap and plug in
place when the access port is not in use.

Electrical Connection
Thermo Fisher Scientific General Purpose Countertop Series User Manual 17
13 Electrical
Connection The equipment is intended for connection to alternating current. The
connection values for voltage (V) and frequency (Hz) are declared on the
name plate in the cabinet. Power must be connected via a wall socket with a
switch. It is strongly recommended that the wall socket is easily accessible.
All earthing requirements are stipulated by the Local Electricity Authority.
The cabinet plug and wall socket should give correct earthing. If in doubt,
contact your local supplier or an authorized electrician.
