GENERAL DESCRIPTION
1.1 INTRODUCTION
The standard range of LMS cooled incubators comprises of nine models, all of
which are available with a range of optional extras to suit individual
requirements. A further two models, 410XAL and 610XAL, which have
special built in features, are also available. Details on request.
1.2 CONSTRUCTION
The outer case of all models in Series 1 and 3 is of sheet steel finished in
white stoved enamel. Foam insulation is used, to ensure maximum insulation
against external ambient temperature. The internal liner of models in Series 1
is of a high impact vacuum formed plastic with a minimum of crevices, and all
corners are radiused. Models in Series 3 have an unobstructed working space
fabricated from polished stainless steel complete with multi position plastic
moulded shelf supports, which allow the three white plastic coated steel
shelves to be randomly positioned to suit individual requirements.
All cooled Incubators within the LMS Series 1 and 3 range incorporate both a
door lock and magnetic gasket with all control features being set into a control
panel and positioned so as to minimise the risk of accidental alteration. Series
4 models have both a stainless steel exterior and interior and come with 5
stainless steel shelves (model 600) and 10 stainless steel shelves (model 1200).
1.3 TEMPERATURE CONTROL
The temperature control method utilises a controller offering digital selection
and readout of temperature.
1.4 COOLING

immediately to the Carrier and Supplier).
(iii) Check that the electrical supply details on the information Rating Plate,
which is fitted to the rear panel, are in accordance with the available
electrical supply.
(iv) All cooled incubators are supplied with a 3 pin moulded plug, which if
not suitable may be replaced by an electrician or other competent
person. Connect conductors as follows: BROWN to live, BLUE to
neutral, GREEN/YELLOW to earth.
(v) Position the cooled incubator so that approximately 100mm of free
space exists around the cooled incubator.
(vi) Adjust levelling foot or feet (depending on model) so that the cooled
incubator sits firmly. Lockable castors (where fitted) MUST be locked.
(vii) Please ensure that the refrigeration switch, which is fitted on the rear
panel on the right hand side, is in the ON position (down).
(viii) After the cooled incubator has been sited allow 24 hours before
switching on.
2.2. CONTROLS –Common to All Models
2.2.1 Fuse
A 1.25" TYPE F cartridge fuse in a screw fitting carrier is located at
the rear of the control compartment adjacent to the Serial Number plate
on which the fuse value is indicated.
2.2.2. Refrigeration Switch
To the rear of the control compartment on the right hand side is the
refrigeration isolator switch. This switch should always be in the ON
position (down) except (A) when the cooled incubator is to be used at
prolonged periods set at an operating temperature of 10ºC or more
above ambient, or (B) when defrosting the cooled incubator.
2.2.3 Non-Adjustable Overheat Protection Device

8
This device is fitted within the air mixing chamber to safeguard the
cooled incubator should a fault condition of overheating develop.
Operation of this device will be indicated by the Red ‘safety’ neon light
on the front panel being illuminated. In the event of this happening the
cooled incubator must be switched off until the reason for the fault
condition is established and the fault itself is rectified.
2.3 TEMPERATURE CONTROLLER
The Digital Controller has been factory tuned for optimum performance. To
obtain the required operational temperature press and hold the * button, the set
point temperature will be displayed (with the programmable temperature
controller the set point temperature, is the lower of the two displays, in
orange). To alter the set point temperature press and hold the * button and
press either the σor τbuttons as required, σto increase temperature, τto
decrease. When the desired set point temperature is achieved, release the *
button. The interior temperature of the cooled incubator will now be displayed
and will gradually adjust until the set point temperature is reached.
2.4 INDICATOR & CONTROL LAYOUT

OPTIONAL EXTRAS WHERE FITTED
ALL NON PROGRAMMABLE MODELS
3.0 AUTOMATIC TEMPERATURE CYCLING
On these models, the digital controllers are mounted either side of a time clock
and will be illuminated in turn according to the time clock settings. (NB –On
changeover the controller will briefly indicate 18.8.8 for few seconds –this is
quite normal).
Changing from one controller to the other is done automatically by a time
switch which can be one revolution every 24 hours or one revolution every 7
days, depending on whether a 24 hour or 7 day clock is fitted.
After removing the time switch cover, time settings can be adjusted by pulling
outwards the segments and reinserting them according to requirements.
To set the time initially, the clock hands can be turned forwards in time
(clockwise) but not backwards (anti clockwise).
3.1 AUTOMATIC DEFROST
On Series 3 and optionally on Series 1, the cabinet is set to defrost for a
duration of 10 minutes in every 6 hours. This defrost will give a slight rise in
air temperature. If this rise should create any problems the defrost can be
over-ridden by the defrost isolator switch at the back of the electrics
compartment. On Series 4 the defrost occurs 4 times every 24 hours;
duration is controlled by the ice build up internally.
On Series 1 and Series 3 cabinets, any defrost water drains away to a tray
mounted on the compressor. On Series 4 cabinets the water drains into a tray
(supplied) which must be fitted in the special tracks mounted underneath the
cooled incubator during installation. On all models this water evaporates
harmlessly away.
3.2 HIGH/LOW ALARM OPTION
The high/low alarm is a manually adjusted alarm option fitted to the
instrument’s front panel.
In the event of an alarm condition, the following action will be taken:
An audible alarm will sound and a secondary safety system will be activated,
preventing the cooled incubator temperature from rising above or falling
below the set alarm limits.

3.3 INNER PERSPEX DOOR
On incubators fitted with this feature and depending on the temperature
difference between the inner working chamber and the space between the
inner and outer doors, some slight twisting may occur.
3.4 CHART RECORDER
Chart Paper Loading (see below)
1. Remove front bezel by simultaneously pressing the retaining
catches on each side.
2. To gain access to the chart paper cassette (1). First unlock the
meter assembly by moving the locking lever (2) to the left and
