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 upon entry.
•Make sure the door is opened as little as possible whilst in use and closed as quickly as
possible to prevent unnecessary temperature fluctuations.
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 freezer and connecting power to the freezer. Also make sure there is good ventilation in the
room. If you are in doubt please contact your supplier.
– WARNING: Keep ventilation openings, in the equipment enclosure or in the built-in
structure, clear of obstruction.
– WARNING: 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
– WARNING: Do not use electrical equipments inside the food storage compartments of
the equipment, unless they are of the type recommended by the manufacturer.

Warning Alarms
This freezer has been designed to provide both an audible and visual alarm should any of the
following situations occur:
•Door is left open for a set period
•Internal air temperature goes outside the set parameters, either too high or too low
•Internal ‘load’ temperature goes outside the set parameters, either too high or too low
Should one of these alarms occur this can be muted by pressing on the controller.
The ‘load’ temperature is a simulated temperature which is intended to provide an indication of
the temperature of the freezer’s contents (e.g. a 5ml sample). The temperature of a freezer’s
contents will change more slowly (up or down) than the air temperature within that freezer
should there be a fault or the door is left open.
Remote alarm contacts
All ES 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. WARNING: 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.
In the event of a door open alarm, high or low temperature alarm or power failure a remote relay
will switch within the controller to make an electrical circuit.
Figure 1 Figure 2

11
Please note that the contacts supplied are voltage free. A voltage of between 12V DC and 230V
AC can be connected at the contacts. The maximum load must not exceed 2A. The minimum
power rating is 500mA / 12V AC.
In a normal condition (i.e. no alarm) the relay OPENS the contact for the remote alarm facility.
In an alarm condition the relay CLOSES the contact for the remote alarm facility.

Maintenance and Service of your ES Series Freezer
Defrosting
All laboratory freezers require manual. In certain conditions (e.g. when the freezer is very full or
when any new items are stored in the freezer) frost may form on the rear wall as the compressor
must run for long periods of time.
Before manually defrosting the cabinet, make sure the power lead is disconnected from the
mains. Any loose frost found on the evaporator can be removed carefully using a wooden or
plastic scrapper.
WARNING: Do not use any knives or sharp metallic objects to remove frost.
Alternatively a non-scheduled defrost can sometimes be carried out as follows:
Cleaning
•Your freezer should be cleaned regularly.
•Before cleaning you MUST switch off and disconnect your freezer from the power
supply.
•The whole freezer except the door gasket can be cleaned with mild cleaning detergent.
•The door gasket should be cleaned with water only and wiped dry.
•The handle should be cleaned regularly with soap and water.
•Remove shelves/basket/door furniture and wipe with a soft cloth. DO NOT put then in a
dishwasher.
•Detergents containing abrasives or acids are not suitable for the cleaning.
•When all cleaning has been completed and accessories replaced, reconnect the plug with
dry hands.

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 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 authorised electrician.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualified persons in order to avoid a hazard.
WARNING: THIS EQUIPMENT MUST BE EARTHED
The flexible cord (mains lead) fitted to this equipment has three cores for use with a 3-pin 13
amp plug. If a BS 1363 (13-amp) fused plug is used it should be fitted with a 13-amp fuse.
The cores in the mains lead are coloured in accordance with the following code:
GREEN AND YELLOW: EARTH
BLUE: NEUTRAL
BROWN: LIVE
These colours might not correspond with the colour markings identifying the terminals in your
