1. IN GENERAL
The Economic Premium is a climate cabinet, in which temperature, humidity and light can be
controlled by a programmable controller, model Jumo IMAGO 500.
To prevent temperature changes, the fluorescent tubes are located outside the working-area behind
isolated glass. The air inside the cabinet is heated by an electrical heating-element. Cooling by a
CFC-free cooling-system. The humidity inside is controlled by the Stulz (de)humidifier.
The cabinet is fitted with 3 trays, all of them adjustable in height. A maximum of 20 trays can be
placed into the Economic Premium. The exterior of the cabinet is made of electrolytic coated steel
in the colours blue and white. The interior of the Economic Premium is made of Stainless Steel. The
cabinet is fitted with a door lock and mounted on 4 swivel-castors.
The controller checks the temperature, humidity, light and CO
2
injection (optional) at fixed time
intervals and takes action when necessary. When no cooling or dehumidification is required, the
compressor will run in a bypass system. This system contributes to a longer lifetime of the
compressor.

3. INSTALLATION
Make sure that the main voltage is as specified in the documentation or as mentioned on the
identification plate of the equipment.
Verify that the equipment was transported in an upright position and has no physical damage. After
installation please wait 4 to 6 hours before switching on the equipment.
Install the equipment in a room sufficiently ventilated, not directly near heatsources and locate it at
least 15 cm from the walls, to make sure that the coolingsystem is optimum ventilated.
The equipment does not work properly at an ambient temperature above +30°C.
Before you put the equipment into use, make sure that the safety-thermostat, located at the leftside
in the machineroom, is set on approx. -5°C & +60°C in order to prevent that an alarm will occur
when the unit will be switched on. These settings can be changed afterwards also.
Note: the high setting of the safety thermostat must be set +5°C above ambient temperature.
Connect the Economic Premium to a direct watersupply by means of a waterhose and open the main
valve. When there is no direct water supply to connect to the Economic Premium, it’s necessary to
place a watertank (optional) at the backside of the machine and connect it to the water supply of the
Economic Premium by means of a waterhose. Please pay attention that the income pressure will be
between 0 and 4 bar. Fill the watertank with water and open the main valve.
Pay attention: never start the machine without a water supply, because this can damage the
magnetvalve of the humidifier.
Standard the Economic Premium is fitted with a wateroutlet (valve), which is situated on the
backside of the cabinet. By opening this valve the water, which is situated on the bottomplate of the
working area, can be removed. Keep in mind that the water will not have influences on the
aircirculation.
Connect the Economic Premium to the main supply and switch on the power.
Program the controller according to the instructions in paragraph 4, 5 & 6.
Note: Snijders Scientific advises to use softened water. You can also use demineralised water,
when the pH value is not below 6,5. Tap water with a hardness of more than 4°D will
influence the lifetime of the humidifier.

4.2. Control
With the controller IMAGO 500 it’s possible to set the temperature, humidity and light by
handmode of a program.
The lighting is divided over 4 different contact groups, which can be set independently of each
other, using contact 1 up to and including 4.
The Economic Premium can be switched on by means of the main power on/off-switch (11). The
red switch on the panel is to switch off the present buzzer (13). Light on: buzzer active, light off:
buzzer not active.
The red led (12) indicates when there is an alarm situation. It lights up when the temperature or
humidity deviates 5°C from the setpoint (above as well as below). Standard a potential free contact
is executed at the backside of the cabinet. When there is an alarm situation this contact will switch
and an external alarmsystem will be activated.
The controller allows settings of 50 different programs. Each program can be built up from a total
day/ night cycle, in which different steps, both in the day and nightperiod, can be performed. Each
program can operate continuously or can be repeated a number of times (between 1 and 99).
Note: when the controller hasn’t been touched for 15 minutes, automatically the screensaver
will start up. By pressing a soft key, the screensaver will go off.
4.3. Display
The display of the controller is fitted with three screens (screens 4-5 are optional):
1. general screen, which shows the temperature, lightposition, remain cycletime and which program is
working in which step (PG & SG)

the humidity setpoint. For the light and CO
2
injection no alarms can occur.
-When the internal temperature and humidity deviates from the settemperature and -humidity, the
buzzer, alarm led and the potential free contact (backside cabinet) will be energized.
-The buzzer is mutable by using the switch on page 7, number 14. The alarm itself stays
energized.
-When the internal temperature is too low the cooling will be switched off. When the internal
temperature will be too high, the heating, lighting & fan will be switched off.
-The safety-thermostats, located at the back of the control panel, are set on the absolute minimum
and maximum safety temperature in order to prevent that an alarm is given when switching on
the unit. Standard these safety-thermostats are set on -5°C & +60°C.

7. MAINTENANCE
- Clean the condenser on the frontside of the cabinet regularly. This can be done with a soft brush
or carefully with a vacuumcleaner. It is preferable to use compressed air when this is available.
- Check the intensity of the fluorescent tubes regularly. This intensity will decrease, as the tubes
will age. If the intensity is not sufficient anymore, the tubes need to be changed.
- Cleaning of the isolated glass results in an optimal transmittance of the light of the fluorescent
tubes.
- The shelves inside the cabinet are made of a stainless steel frame with a polystyrene inlay. These
shelves may not be sterilized and must be cleaned with a cleaning-solution or with a
desinfection solution.
- The cabinet can be cleaned with a cleaning-solution or a desinfectant. Acids will make the
stainless steel corrode and are therefore not recommended to use.
- Check regularly if the waterlevel isn’t too high because of the sealing off of the aircirculation.
7.1. Warnings
- When the exhaust is blocked, or the airflow severely deranged, accuracy of the temperature will
decrease.
- Maximum 600W can be connected to the AC-outlet (optional).
- The cabinet must be cleaned thoroughly on a regular basis, to secure optimal functioning.

7.2. Use of water for the humidification
It’s possible to use water from the tap. However, it’s advisable to use softened water when this is
available. Check regularly the operation of the humidification unit, which is located in the technical
compartment.
When the humidification is active, a plume with humid air will come out of the humidification
pipes.
When the climate cabinet isn’t used for a longer period of time, the humidification-unit has to be
emptied. This can be done by removing the black stop at the left side of the unit.
Pay attention! Collect the outcoming water by using a tube and bucket.
Warning:
When the humidification unit is not been emptied, when it’s not used for a longer period of
time, lime dismissal will appear at the membranes. This reduces the lifetime of the unit!
Note: please see chapter 3, installation.
