1 General notes and safety notes You have purchased a technically fully proven product which has been produced in Germany with the use of high-grade materials and the application of the latest manufacturing techniques; it has been factory tested for many hours. For this unit we guarantee availability of spares for 10 years Observation of the Operating Instructions is necessary forfaultless operation and for any possible claims under warranty.
2 Installation It is important that the oven is set up accurately horizontally; the door may have to be adjusted (see section 21) cm min. 20 The oven can be placed on the floor or on a bench (working surface). min. 8 min. 8 min. 15 cm cm cm The spacing from the back of the oven to the wall should be at least 15 cm. The spacing to the ceiling must not be less than 20 cm and that at the side to the wall not less than 8 cm. Generally it is essential to have adequate air ventilation around the oven.
2.3 Initial start-up When the oven is started up for the first time, it should be supervised continuously until steady conditions have been reached. Severe vibrations during transport may cause movement of the temperature probes in their holder inside the chamber. Note therefore that before the first start-up the temperature probes should be checked for their correct position and, if necessary, carefully aligned in their mounting (see ill). 2.

3.3 Material quality For the external housing MEMMERT employs stainless steel (Mat.Ref. 1.4016). The chamber is made from stainless steel (Mat.Ref. 1.4301) which exhibits high stability, optimal hygienic properties and corrosion resistance against many (not all) chemical compounds (care required e.g. with chlorine compounds). The oven load has to be checked carefully for its chemical compatibility with the above materials. A compatibility table for materials can be requested from MEMMERT.
4 Oven construction and operation 1 2 1 1 1 1 3 The special feature of the HCP is the particularly uniform conditions inside the chamber. The air is heated by large-area allround heating (1). Humidity is provided by a dry steam generator which produces controlled evaporation of the water. The sterile dry steam is introduced into the chamber above the fan and mixed into the air flow (2). A continuous uniform atmosphere is ensured by the turbulence-free chamber ventilation (3). 4.
4.3 Switching on The oven is switched on by pressing the push/turn control. Oven switched off. The push/turn control is pushed in and protected against damage. Oven switched on and can be operated using the push/turn control and the SET key. 4.4 Setting the temperature (quick setting) Hold down the SET key and set the temperature setpoint with the push/turn control. After the SET key has been released the display briefly flashes the temperature setpoint.
7 Normal operation PRINT SETUP In this operating mode the oven operates continuously. The settings for operating the oven can be selected. The settings act directly on the operation of the oven.
Setting example Normal operation The unit has to heat up to 50°C at a humidity of 95%rh. The monitor function has to be activated at 51°C. temperature °C relative humidity (rh) % 100 100 80 80 60 60 temperature monitor 40 40 20 20 time time 1. Select operating mode “Normal operation“ After holding down the SET key (approx. 3 sec), the current operating mode is flashing. Select operating mode I with the push/turn control while holding down the SET key.
8 Weekly programmer PRINT SETUP In this operating mode the weekly programmer is activated and the oven switches on and off automatically at the programmed times. While the weekly programmer is in the OFF phase the unit is in stand-by mode. Heating and the supply of humidity are switched off, the controller display is dimmed and shows the clock time. The sequence of the weekly programmer is repeated every week. A maximum of 9 time blocks, each consisting of ON time and OFF time, can be programmed.
Programming example Weekly programmer The unit has to switch on at 9.30 hrs from Mo to Fr (workday group) and switch off at 19.00 hrs. In addition it has to operate on Saturday from 10.00 to 14.00 hrs. 9:30h - 19:00h Fr Su 9:30h - 19:00h Th 9:30h 14:00h 9:30h - 19:00h We Sa 9:30h - 19:00h Tu 01:00h 9:30h - 19:00h 12:00h Mo 24:00h 1.

10 Printer PRINT SETUP All HCP ovens are fitted as standard with a parallel printer interface, as used on personal computers. This parallel printer interface on the back of the oven is suitable for connecting conventional PCL3compatible printers which are provided with a parallel printer interface (e.g. HP Deskjet 5550 or HP Deskjet 9xx). It is important to use a screened interface cable. The screen must be connected to the plug case.
11 Basic oven settings (Setup) PRINT SETUP In this operating mode it is possible to make the basic settings of the oven. Clock time, date, day, year, and settings of sounder, of address assignment, monitoring units, heater power and calibration are set here.
Calibration correction for user-calibration (see section 17) Exit setup mode = store all settings and exit SETUP mode 11.1 Real-time clock The real-time clock is set in SETUP and includes date and clock time. The real-time clock serves for documentation according to GLP. Date and clock time are marked in the report print. On the graphics print the time axis is marked in real-time. The clock runs with a buffer battery independently of the mains power supply.
12.2 Electronic temperature monitor 12.2.1 Overtemperature protection Adjustment range: up to 10°C max above nominal temperature (for nominal temperature see label) °C MAX MIN Using the push/turn control select the symbol MAX . Hold down the SET key and set the protection temperature using the push/turn control. AUTO 12.2.2 Undertemperature protection Adjustment range: from 10°C below minimum temperature of oven to 10°C above nominal temperature of oven (for nominal temperature see label).
12.2.4 Automatic temperature monitor (ASF) A monitoring device which automatically follows the selected temperature setpoint. Automatic temperature monitor OFF °C (ASF OFF) Using the push/turn control select the symbol AUTO . Hold down the SET key and select off using the push/turn control. MAX MIN AUTO Automatic temperature monitor ON °C (ASF ON) Using the push/turn control select the symbol AUTO . Hold down the SET key and select on using the push/turn control.
Going outside tolerance margin = ASF alarm Going outside the selected tolerance margin of the setpoint (in the example 37°C, +/-3°C), for example through opening the oven door during operation, triggers the alarm. Triggering the ASF alarm is indicated by flashing symbol AUTO and . If the sounder is switched on in SETUP, the ASF alarm is additionally signalled by an interrupted tone. By pressing the SET key the sounder can be switched off temporarily until the next occurrence of an alarm event.
Setpoint changed = ASF de-activated automatically If the temperature setpoint is altered, the automatic temperature monitor is automatically de-activated temporarily (see in the example the setpoint is changed from 37°C to 30°C) until the tolerance margin of the new temperature setpoint is reached (see in the example below: the ASF is re-activated at 30°C, +/3°C).
14 Audible alert signals The interval sound indicates a fault in the temperature control system or the humidifying system. It is triggered in the following cases: Fault in the temperature control system: Tb activ - temperature limiter activated if the temperature limiter operates (see section 12.1) hi-alarm - overtemperature alarm activated if the overtemperature protection operates (see section 12.2.3) lo-alarm- undertemperature alarm activated if the undertemperature protection operates (see section 12.2.
15 Sterilisation chip card Sterilisation Parameter: 160 °C / 4:00 h Unit-ID: ________________________ Sterilisation Process Control Card As protection against contamination the HCP is equipped as standard with a STERICard. The STERICard starts an automatic and pre-set sterilisation procedure. To activate, insert the STERICard into the slit in the control field, select the Start symbol turn control and the depressed SET key.
16 User-ID-Card (available as optional extra) Name: _____________________ ID: _____________________ access authority card The User-ID-Card stores the serial number of the oven and a unique user number in encrypted format. The User-ID-Card therefore functions only in the oven with the corresponding serial number. Each log-on via the User-ID-Card is documented in the internal flash memory. If the USER-IDcard is inserted, the SETUP menu includes the additional item ID-LOCK.
17 Calibration 17.1 Temperature User-calibration of oven at the controller, with three calibration temperatures selected by the user. CAL.1 Temperature calibration at low temperature CAL.2 Temperature calibration at medium temperature CAL.3 Temperature calibration at high temperature Either a positive or a negative calibration correction can be applied to each selected calibration point.

18 Communication interface for the PC 18.1 Communication interface RS232C The oven is provided as standard with a serial communication interface RS232C according to DIN 12 9001. Using this interface it is possible to control the oven from the PC and to produce reports. This is done using the “Celsius 2007“ software. For this purpose the oven has to be assigned a unique device address in sub-menu SETUP, option ADDRESS; This is the address through which the PC communicates with the oven.
18.2 Bus interface RS485 When so ordered, the oven can be equipped at the factory with an RS485 interface instead of the RS232C interface. This permits networking of several ovens (up to 16) with a single PC using a common 2-wire circuit. The system is operated using the “Celsius 2007” software. A unique device address has to be assigned to the oven in sub-menu SETUP, option ADDRESS. This is the address through which the PC communicates with the oven. The default setting is ADDRess 0.
19 Report memory The controller continuously records all relevant measurements, settings and error messages at 1-minute intervals. The internal report memory is arranged as a ring memory, i.e. the new data always overwrite the oldest report data. The report function can not be switched off but remains active at all times. The data are stored in the controller, protected against any manipulation. The controller memory can be read to produce documentation. Every data set is stored with a unique date stamp.
20 Cleaning By regular cleaning of the (easy to clean) interior, residues are avoided which may impair the outfit and function of the incubator. The unit can be cleaned with commercial stainless steel cleaning agent. Please note that objects liable to rust must not be placed into the interior. Rust sediments lead to contamination of the interior or the external casing. If rust stains caused by contamination occur on the interior surface, the affected areas must be cleaned and polished immediately.
21 Maintenance Important for a long life of your MEMMERT product and in case of warranty claims. Note: Any work involving opening up the oven must only be carried out by a suitably qualified electrician! MEMMERT products require little maintenance. It is however recommended to lubricate all moving parts of the doors (hinges and closure) once a year (or 4 times a year with continuous operation) using a thin Silicone grease, and to check that the hinge screws are tight.
