2 General
RUMED cooled incubators are producing ideal thermal conditions for quality control and research in science
and industry. Experiences of almost 50 years stand for a maintenance-free construction and result in longevity.
Cooled incubators are fabricated for two different temperature ranges and three unit sizes each can be chosen
from. The options alternating temperature control and programme control, lighting and humidification increase
the unit's universal applicability. Depending on equipment, the units are applicated in zoology, botany,
microbiology, bacteriology, medicine as well as in the artificial aging and testing of electric and electronic
components.
3 Transportation and Storage
The standard domestic shipment of the unit will be effected unpacked in a van. The unit should be
transported carefully in standing position. In case a short-time tilting of the unit should be unavoida-
ble, for reasons of f. ex. passing doors, it might be possible that oil of the cooling machine will enter
into the evaporator. This oil must flow back to the cooling machine. For this reason take care that
after transportations the unit should not be started before expiration of 4 hours. The unit is recommen-
ded to be stored in dry rooms at temperatures between +10°C and +30°C. The shipment within
European countries is mostly effected in stable cartons on a palette. Seaworthy and air-freight cases
are generally conserved for 12 months and the units are welded in an aluminium wrapping. Conden-
sation due to passing of different climatic zones is avoided by drying agent bags which are to be
removed prior to initial starting of the machine.

• Installation places being exposed to direct sunlight, radiators and other thermal sources are to be avoided.
Insufficiently ventilated rooms and room temperatures exceeding +25°C are also unsuitable.
• The distance between the wall and the backside of the unit should be at least 10 cm. Do not cover the
ventilation slots; even a partial covering of the slots may lead to a heat accumulation.
Uncovered ventilation slots are very important for a faultless operation of the cooling machine!
• The floor of the installation place should be even and horizontal. Slight unevennesses can be balanced by
the adjustable foots of the unit.
• Units being equiped with the option "Ultrasonic Humidification" must be installed in such a way, that the test
room bottom is in level position to ensure a correct drain of water.

The unit is not explosionproof!
Do not store explosive or easily inflammable substances in the test room!
5 Power Supply
• Current (A.C.) and voltage at the installation place must coincide with the indications on the name-plate of
the unit. The name-plate can be found at the upper part in the door frame on the left side.
• Connection is to be made to a duly earthed socket (a separately secured socket is recommended).
A multitude of units are equiped with combined universal plugs according to the German or French
standard.
6 Operation
It is recommended to clean the interior of the unit before starting. Refer to the details described in "Defrosting"
and "Cleaning" (chapter 12).
Open the door widely for removal of the insertion grids. The grids must be charged in such a way that a
circulation of the air will not be hindered.
The white rocker switch "Circulating Air" starts the fan and the unit at the same time. Cooling machine and
heating are locked by means of this switch and will be only started when the fan is in operation. On operation
of the fan the white pilot lamp is lighting.
In case the fan is fitted with a potentiometer, the air quantity can be reduced by turning the control knob to the
left.
The red rocker switch "Heating" and the blue rocker switch "Cooling" are to be switched-on.
The refrigerating machine will only start when cooling capacity is requested. On demand of cooling, the
temperature controller switches to the cooling circuit by means of a solenoid valve, and when there is no
request for cooling, it switches to the bypass-circuit. Should the period where no cooling is requested
exceed 3 minutes, the refrigerating machine will be switched-off. The blue pilot lamp will only light-up on request
of cooling capacity (cooling circuit is switched-on), the pilot lamp "heating" will only light-up on request of
heating capacity.
The test room socket (option) is switched-on by means of the yellow rocker switch ("plug socket") and the pilot
lamp is lighting. The test room socket can be charged by max. 4 Amps. In case of an overload or a failure of the
connected unit, the safety cut-out being located next to the switch on the right side will be released. Upon
repair of the failure, the pin of the safety cut-out shall be pressed down again.

7 Temperature Control
7.1 Temperature Controller
Functioning
The digital temperature controller
can be used as constant value
controller or, with optional acces-
sories, as programme controller.
Temperature sensor is a Pt 100
resistance thermometer, class A.
Further technical details can be
drawn from the PHILIPS Operating
Instructions No. 9499 040 21601.
7.2 Setpoint Control
The temperature controller keeps the test room temperature constant on an adjusted value. Actual value and
setpoint are displayed simultaneously on two different digital displays being located upon another. The upper
digits indicate the actual value, the lower digits the setpoint. The setpoint value can be decreased or increased
by pressing the keys and .
7.3 Programme Control
The option dual setpoint daily programme is achieved by configuration of the temperature controller as
programme controller. This option offers the possibility of a change between two temperatures with
programmable values for the temperature variation speed (ramps). The programme can be started at any
desired moment by the switching command (1 ON) of the timer. The switching command (1 OFF) terminates the
programme. The moment for the switching command OFF results from the running time of the programme.
During the programme cycle "W2" is displayed.
The timer can be operated in the switching modes "Auto", "Permanent ON" and "Permanent OFF". For
programme control, the timer must be switched to position "Auto". For a commutation to setpoint control, the
timer must be switched to "Permanent OFF". The controller will then be operated as setpoint controller and all the
programmed parameters will be kept in the controller as well as in the timer.
As soon as the timer is commutated again to "Auto", the programme control is reactivated (See chapter 7.4
"Programme Timer for Alternating Temperature" -> "Change of Switching Status").

7.4 Programmable Timer for Alternating Temperatures
General
The digital timer can be operated in the operating modes "daily programme" and "weekly programme". It is
recommended to programme the daily reiterating day-/night temperature change in the operating mode "daily
programme". (The small triangle in the display must aim to 1->7; if not, the "weekly programme" of the timer is
activated. Change of the operating mode is effected by a reset of the timer.
Reset of the Timer and Selection of the Mode "Daily Programme"
Please observe the following four steps exactly for starting the timer in the daily programme mode.

Daily Programme
When the mode "daily programme" is activated, maximum 6 ON- and 6 OFF-commands can be
programmed. However, for one programme cycle only 1 ON- and 1 OFF-command is required. The
command ON starts the programme, the command OFF terminates the programme. At the same time,
a programme reset is effected in the temperature controller, which is the only possibility for a further
programme start.
Correspondingly, the time delay between an OFF-command and the next ON-command must be at
least 1 minute, otherwise the programme reset cannot be effected and the programme controller will
not change to the next programme cycle (i. e. in the operating mode "daily programme" it is possible to
run a four-hour programme cycle six times per day maximum).
The following table shows the programming of the response times for our dual setpoint programme
example.
