Safety Regulations 1. Safety Regulations 1.1 Terms and signs used In this manual, certain common terms and symbols are used to warn you of dangers or to give you hints that are important in avoiding injury or damage. Observe and follow these hints and regulations to avoid accidents and damage. These terms and signs are explained below. 1.1.1 Terms used "Warning" is always used whenever you or somebody else could be injured if you do not observe the accompanying safety regulation.
Safety Regulations 1.2 Product safety and dangers ICH cooled incubators are technically sophisticated, manufactured using high-quality materials and subject to many hours of testing in the factory. They contain the latest technology and comply with recognised technical safety regulations. However, there are still dangers involved, even when the appliance is used as intended. These dangers are described below. Warning! After removing covers, live parts may be exposed.
Safety Regulations 1.2.2 Additional safety regulations for cooled incubators with CO2 supply. Warning! Danger of suffocation. CO2 can have a suffocating effect in high concentrations. In normal operation, the cooled incubator gives off small amounts of CO2 to its surroundings. You should therefore ensure that the room in which it is installed is properly ventilated. Always close the stop valve or pressure reducer on the gas bottle if there is no gas bottle connected or if the bottle connected is empty.

It is used for logging purposes in accordance with GLP.
Advanced Functions 7.3.1 Mechanical temperature monitoring: Temperature limiter (TB) The cooled incubator is equipped with a mechanical temperature limiter (TB) of protection class 1 in accordance with DIN 12880. If the electronic monitoring unit should fail during operation and the factory-set maximum temperature is exceeded by approx. 20 °C, the temperature limiter, as the final protective measure, switches off the heating permanently. As a warning, the icon lights up.
Advanced Functions Setting: Overtemperature protection: Adjustment range: up to max. 10 °C above nominal temperature (for details of the nominal temperature, see nameplate) Setting: 1. Select the MAX icon with the push-turn control. 2. Hold down the SET key and set the desired temperature limit with the push-turn control (e.g. to 38.5 °C).
Advanced Functions 7.3.3 Automatic temperature monitor (ASF) ASF is a monitoring device that automatically follows the set temperature setpoint within an adjustable tolerance band (Fig. 25). The ASF is activated – if switched on – automatically if the actual temperature value reaches 50 % of the set tolerance band of the setpoint (in the example: 37 °C – 1.5 °C) reached for the first time (section A). The activation of the ASF is shown by the brightly lit AUTO icon.
Advanced Functions 7.4 Communication interfaces 7.4.1 USB interface The cooled incubator is equipped by default with a USB interface. In accordance with USB specification (see Fig. 5 on page 14). With this interface, it is possible to control and log the appliance remotely from the computer. This is done with the help of the “Celsius“ software.
Advanced Functions 7.5 Log memory The controller continually logs all relevant measured values, settings and error messages at 1-minute intervals. The internal log memory is listed as a ring buffer, i e. the oldest log data is always overwritten automatically with new data. The logging function cannot be switched off and is always active. The measured data are stored in the controller, safe from manipulation.
Advanced Functions Due to this automatic defrosting, there is a minor brief increase in the chamber temperature at regular intervals. If you would like to further reduce this detraction in performance, you can decrease the defrosting frequency, e.g. to every 24 hours. In this case, please observe if there is a permanent drop in the cooling performance or a strong fluctuation of the actual value, which may be an indication that the cooling unit is icing over.
Advanced Functions For each selected balance point (Fig. 28), a positive or negative compensation correction value can be set between -2.9 ºC and +2.9 ºC. There must be a difference of at least 10 ºC between each of the individual balance points.

With a reference instrument, measure the deviation in the stationary state in the selected CO2 balance point. 3. Under SETUP, adjust the compensation correction value. If the measured reference CO2 content is too low, the compensation correction value must be set with a negative sign. 4. Perform a control measurement with the reference instrument. 5.
Maintenance and Servicing 8. Maintenance and Servicing 8.1 Cleaning Warning! Danger of injury by electric shock. Before any cleaning work, pull out the mains plug. 8.1.1 Interior and metal surfaces Regular cleaning of the easy-to-clean interior prevents build-up of material remains that could impair the appearance and functionality of the stainless steel chamber over time.
Maintenance and Servicing 8.1.4 Cooling compressor In order to guarantee perfect function and long lifetime of the refrigeration unit, it is absolutely essential to remove dust deposits from the condenser (Fig. 33, no. 1) (with a vacuum cleaner, paintbrush or bottle brush, depending on the amount). After the screws (2) have been loosened, the air inlet cover on the front (3) can be removed and the condenser can be cleaned.
Maintenance and Servicing 8.3 Replacing fluorescent tubes (only for models with interior lighting) Caution: ► Replace the fluorescent tubes only with fluorescent tubes of the same type; e.g. UV light tubes only with UV light tubes, not daylight tubes. For information on the specifications, please refer to chapter "Technical data" on page 17. ► Do not replace single tubes, but always the entire tube set (e.g. all UV light tubes instead of just one). Replacing single tubes can influence the light output. 1.
Maintenance and Servicing 5. Unlock the plastic fixing of the tubes that need to be replaced on both sides and pull out the tubes carefully (Fig. 38). 2 1 1 2 Fig. 38 1 Remove the plastic fixing and slide to the middle. 2 Pull the tubes carefully out of the holder. 6. Insert new tubes and screw tight. 7. Attach the glass cover and fix it with the restraining plate. To do so, screw in the two Allen screws on the side again. 8. Put the illumination box back into the cooled incubator. 9.
Maintenance and Servicing 8.4 Adjusting door A well-closing door is indispensable for cooled incubators. Thanks to the combination of a chamber seal and a door seal, MEMMERT appliances optimally guarantee the tight closing of the door. In permanent operation, the flexible seal material might begin to sag. To ensure that the door closes exactly despite this, an adjustment may be necessary (Fig. 39).
Storage and Disposal 9. Storage and Disposal 9.1 Storage The cooled incubator may only be stored under the following conditions: ► in a dry and enclosed, dust-free room ► frost-free ► disconnected from the power supply and gas supply Disconnect the gas bottle and close the valve of the gas bottle. Gas bottles may be stored in closed rooms if these are sufficiently well ventilated. Disconnect the tube of the water supply tank and empty it. 9.
