Construction and description 2.2 Description The appliance can heat the working chamber up to 70 ºC and cool it down to 5 ºC. Low- noise, long-life and energy-saving Peltier cooling and heating technology is used for this. In heating operation, a part of the required energy is extracted from the surroundings (heat pump principle). Additionally, the humidity in the interior of constant climate chambers HPP can be regulated between 10 and 90 % rh (rh = relative humidity). The humidity is increased by water from a tank being evaporated and fed into the interior, and is reduced through condensation on a Peltier module. Optionally, the appliance can be equipped with a light module, making it possible to adjust the interior lighting in steps of 1 %. 2.3 Working range of constant climate chambers HPP The temperature-humidity diagram (Fig. 3) specifies at what range of temperature and humid- ity a permanent, condensation-free operation of the constant climate chamber HPP is possible. Caution: If in operation for long periods at the upper level or outside the working range, puddles of water may form inside the chamber and water may force its way out of the door seal. 0 10 20 30 40 50 60 70 80 90 100 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 Temperature °C Humidity % rH C A B Fig. 3 Temperature-humidity working range of constant climate chambers HPP (at an am- bient temperature of 22 °C ± 3 K, relative humidity < 50 %)

11 Construction and description Range A: In this range, temperature and humidity can be combined as you please, without resulting in any significant condensation. If there are extreme ambient conditions, the working range may be restricted. Range B: If the specified range is exceeded upwards, e.g. 80 % rh at 60°C, the hot steam fed in will im- mediately condense, due to the dew-point, at the coldest point in the appliance. Range C: At low temperatures and low relative air humidity, the effective range is heavily dependent on the degree of humidity of the chamber load. 2.4 Material For the outer housing, MEMMERT deploys stainless steel (Mat.No. 1.4016 – ASTM 430) and for the interior, stainless steel (Mat.No. 1.4301 – ASTM 304) is used, which stands out through its high stability, optimal hygienic properties and corrosion-resistance towards many (but not all!) chemical compounds (caution for example with chlorine compounds). The chamber load for the appliance must be carefully checked for chemical compatibility with the materials mentioned. A material resistance table can be requested from the manufacturer. 2.5 Electrical equipment ►Operating voltage and current consumption: See nameplate ►Protection class I, i.e. operating insulation with PE conductor in accordance with EN 61010 ►Protection type IP 20 acc. to EN 60 529 ►Interference suppression acc. to EN 55011 class B ►Appliance fuse: Fusible link 250 V/15 A quick-blow ►The temperature controller is protected with a miniature fuse 100 mA (160 mA at 115 V) 2.6 Connections and interfaces 2.6.1 Electrical connection This appliance is intended for operation on an electrical power system with a system imped- ance Zmax of a maximum of 0.292 ohm at the point of transfer (service line). The operator must ensure that the appliance is operated only on an electrical power system that meets these requirements. If necessary, you can ask your local energy supply company what the system impedance is. Observe the country-specific regulations when connecting (e.g. in Germany DIN VDE 0100 with residual current circuit breaker).

The maximum number or grids / shelves and the load capacity are specified in the technical data overview from page 14 . The chamber must not be loaded too tightly, so that proper air circulation in the working chamber is guaran- teed. Do not place any of the chamber load on the floor, touching the side walls or right below the ceiling of the working chamber (Fig. 16, see also the "correct loading" sticker on the appliance). In case of improper loading (chamber loaded too tightly), the set temperature may be exceeded or it may take longer until it is reached. To achieve the correct heating capacity, the type of slide-in unit used – Grid or Shelf – must be set in the menu under SETUP (see page 48). 5.4 Operating the appliance 5.4.1 ControlCOCKPIT In manual operation, the desired parameters are entered at the ControlCOCKPIT on the front of the appliance (Fig. 17 and Fig. 18 ).

This serves to avoid damage to the chamber load and/or appliance in case of a malfunction: ► electronic temperature monitoring (TWW) ►automatic temperature monitor ( ASF) The monitoring temperature of the electronic temperature monitoring is measured via a separate Pt100 temperature sensor in the working chamber. Temperature monitoring settings are made via the ALARM display. The settings made apply to all operating modes. If temperature monitoring has been triggered, this is indicated by the temperature display: the actual tempera- ture is highlighted in red and a warning symbol is shown ( Fig. 19 ). The type of temperature monitoring triggered (TWW in this example) is shown beneath the temperature. If the acoustic alarm has been activated in the menu mode (Sound, see page 57, indicated by the speaker symbol in the alarm display), the alarm is additionally signalled by an intermittent acoustic signal, which can be turned off by pressing the confirmation key. Information on what to do in this case are provided in the chapter Malfunctions, warning and error messages on page 40. Before reading how to adjust temperature monitoring (from page 35), please read the description of the individual monitoring functions here.

Operation and control Electronic temperature monitoring ( TWW) The manually set monitoring temperature min and max of the overtemperature control is monitored by an adjustable over/undertemperature controller (TWW) protection class 3.3 acc. to DIN 12 880. If the manually set monitoring temperature max is exceeded, the TWW takes over temperature control and begins to regulate the monitoring temperature (Fig. 20). t °C Setting MAX Set temperature Controller error Emergency operation Fig. 20 Schematic diagram of how TWW temperature monitoring works

35 Operation and control Automatic temperature monitor ( ASF) ASF is a monitoring device that automatically follows the set temperature setpoint within an adjustable tolerance band (Fig. 21). The ASF – if switched on – is automatically activated as soon as the actual temperature value reaches 50 % of the set tolerance band of the setpoint (in the example: 50 °C ± 1 K) for the first time (section A). When the temperature violates the set tolerance band around the setpoint (in the example in Fig. 21: 50 °C ± 2 K) – e.g. if the door is opened during operation (section B of illustration) – the alarm is set off. The ASF alarm is automatically triggered as soon as 50 % of the set tolerance band of the setpoint (in the example: 50 °C ± 1 K) are reached again (section C). If the temperature setpoint is altered, the ASF is automatically disabled temporarily (in this example: The setpoint is changed from 50 °C to 25 °C, section D) until the tolerance range of the new temperature setpoint is reached again (section E). 52°C 48°C ASF active 52°C 48°C ASF alarm ASF active ASF active 27°C 23°C °C 50°C 25°C t A B C D E AUTO AUTO AUTO Fig. 21 Schematic diagram of how the ASF temperature monitoring works Adjusting temperature monitoring ►For cooled incubators IPPplus: Press the activation key to the left of the ALARM display.
