1.3 General
RUMED Climatic Test Cabinets are producing ideal thermal conditions for quality control and research as well
as development in science and industry. Experiences of more than 50 years stand for a maintenance-free
construction and result in longevity.
Climatic Test Cabinets are produced in two different temperature ranges, and three unit sizes each can be
chosen from. Standard test atmospheres according to DIN 50014 and constant test atmospheres according to
DIN 50015 can be run in the standard units. The options temperature- and humidity programme control ensure
the test method in damp alternating atmospheres according to DIN 50016. Standard atmospheres ensure
attaining and maintaining of a defined state of temperature- and humidity-sensitive objects. Constant test
atmospheres allow selected stress tests in the range of tempered, damp or dry heat atmospheres for testing of
temperature- and humidity-sensitive objects. The method of test in damp alternating atmospheres serves mainly
for tests on units, structural components and humidity-proof packing material in view of its applicability at
increased humidity of the air and temperature alternations causing condensation water or dew.
All models are equiped with artificial air circulation, if requested with control. Thus, a high temperature accuracy
in space and time according to the DIN-regulation 58945 is obtained.

The unit is not explosionproof!
Do not store explosive or easily inflammable substances in the test room!
2 Safety, Transportation and Installation
2.1 Safety
It is recommended to clean the interior of the unit before starting. Refer to the details described in "Defrosting"
and "Cleaning" (chapter 7).
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 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.
Option Test room socket:
The test room socket can be charged by max. 4 Amps.
2.2 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
unavoidable, 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 recommended 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. Condensation 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.

2.3 Installation
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.

2.4 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.

2.5.2 Operation with Demineralized Tap Water
Connect water intake of the humidifier with the
furnished hose to a demineralized water supply
according to DVGW (German Supply Company for
Gas/Water) which can be shut-off.
2.5.3 Operation with Demineralized Water from a
Supply Vessel
Suspend a ventilated supply vessel (recommended
volume: 10 liters) minimum 1 m above the level of
the humidifier and connect it to the water intake of
the humidifier by means of the furnished hose.
2.5.4 Operation with Tap Water
It is not possible to operate the humidifier with
directly supplied tap water. If only tap water is
available, the water must be supplied through an ion
exchanger connected in series. Connect water
intake of the ion exchanger with the furnished hose
to a tap water supply according to DVGW (avoiding reflux) which can be shut-off.

3 Start-up
3.1 General
... The unit can be switched on and off by means of the softkey ON/OFF .
Since the connection and disconnection is effected by a software switch, the mains plug is always to be
withdrawn in case of maintenance tasks to ensure that the unit is completely disconnected from the mains.
When the unit is reconnected to mains (insertion of the plug into the socket), the display of the controller will be
lighting for some seconds, and the controller will be returned to that operating mode which had been active prior
to disconnection from mains (withdrawal of the mains plug).
Connection and disconnection can only be effected on entry of the password of operating level 1.
After the first start-up (cold unit), the display might appear to be not uniform and poor in contrast. This effect will,
however, disappear, as soon as the working temperature of the display is reached.
If required, the contrast can be adjusted in the actual value screen using the keys .
