2 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.
In addition we guarantee the supply of spare parts over 10 years.
Observation of the Operating Instructions is necessary for faultless
operation and for any possible claims under warranty. If these
Instructions are disregarded, all claims under warranty, guarantee and
indemnification are excluded!
The right to technical modifications is reserved.
Dimensional details are not binding.
2.1 Transport

3 Installation facilities (accessories)
The oven can be placed on the floor or on a
bench (working surface). It is important that
the oven is set up accurately horizontally; the
door may have to be adjusted (see Section:
„Maintenance“)
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.
Model HPP 108 is mounted on castors. The front castors pivot and can be locked. In order to ensure the
stability of the oven the front castors must always be set facing towards the front.
Information on accessories will be found in our leaflet or on our internet page www.memmert.com.
Please note the installation instructions for our accessories.
3.1 Subframe
Model HPP 108 can be mounted on a subframe (accessory)
3.2 Stackable version
Two HPP 108 ovens of the same model size can be stacked on each other. Note
that the oven with the lower working temperature must always be placed at the
bottom.
Foot locators (accessory) have to be fitted on the bottom oven.
Take off cover of bottom oven•
Place drill jig (supplied with foot locators) into the inverted cover at the •
back
Mark holes and drill 4.2 mm dia.•
Screw the foot locators to the top of the cover using the screws and nuts •
supplied
Re-fit the cover•
Page 6
HPP page 6
3.3 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).
3.4 Oven load
Full consideration must be given to the physical and chemical properties of your load (e.g. combustion
temperature etc.) in order to prevent serious damage to load, oven and surroundings.
Please note that the MEMMERT ovens described here are not explosionproof (they do not conform to the
Industrial Association Specification VBG 24) and are therefore not suitable for drying, evaporating and
burning-in of paints, enamels or similar materials whose solvents may produce an inflammable mixture
with air. There must be no possibility of the formation of inflammable gas/air mixtures either within the
oven chamber or in the immediate surroundings of the equipment.
Large amounts of dust or corrosive fumes inside the oven chamber or in the surroundings of the equipment
may produce deposits within the oven and lead to short-circuits or damage the electronics. It is therefore
important that adequate precautions are taken against excessive dust or corrosive fumes.
In order to ensure proper air circulation inside the chamber, there must be sufficient spacing of the load
inside the oven. Do not place any load on the floor, against the side walls or underneath the ceiling of the
chamber (heating ribs). In order to ensure optimum air circulation the shelves must be so inserted that the
air spacings between door, shelf and rear chamber wall are approximately equal.
The maximum number and the loading of the shelves can be found in the table in the Section „Technical
Data“. With unfavourable loading (too closely spaced) it is possible that the set temperature may be
reached only after a longer period of time.
See stick-on label “Correct Loading“ on the oven!

4.1 Working range of the HPP units
The temperature-humidity diagram of the humidity chamber HCP indicates the range of temperature and
humidity within which continuous condensation-free operation is possible.
Range A:
Within this range, any combination of temperature and humidity is possible without any appreciable
condensation.
Range B:
Above the range indicated, e.g. 80% rH at 60°C, the steam introduced immediately condenses at the
coldest point of the unit due to the dew point.
With prolonged operation at the upper limit or outside the working
range there is a possibility of water puddles forming inside the chamber
and water can escape from the door seal!
Range C:
At low temperatures and low relative humidity, the usable range depends largely on ambient temperature
and humidity.

4.7 Water connection
The water container supplied has to be filled with distilled water and connected to the H2O connection
using the hose supplied.
4.3 Material quality
For 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, optimum hgygienic properties and corrosion
resistance against many (not all) chemicals (warning against e.g. chlorine compounds).
The oven load has to be checked carefully for its chemical compatibility with the above materials.
A compatibility table covering all these materials can be requested from MEMMERT.

16 Calibration
User-calibration of oven and controller, with three calibration temperatures selected by the user.
CAL1 temperature calibration at low temperature
CAL2 temperature calibration at medium temperature
CAL3 temperature calibration at high temperature
Either a positive or a negative calibration correction can be applied to each selected calibration point.
General calibration instructions:
1. Select the required calibration temperature in SETUP and set the corresponding calibration
correction to 0.0°C.
2. Measure the deviation from the selected calibration temperature under steady conditions, using a
reference instrument.
3. Set the calibration correction in SETUP. If the measured reference temperature is too low, the
calibration correction setting has to have a negative sign.
4. Carry out a check measurement using the reference meter.
5. The procedure can be carried out for up to 3 calibration temperatures.
Example: Correction of a temperature deviation in the load at 20°C.
1. Set calibration temperature CAL.2 to 20.0°C in SETUP and set the corresponding calibration
correction to 0.0°C.
2. Using a calibrated reference instrument, an actual temperature of 19.6°C is measured in normal
operation for a setpoint temperature of 20°C.
3. In SETUP set the calibration correction for CAL.2 to –0.4°C.
4. After the oven has settled down the reference instrument should read 20.0°C.
5. With CAL.1 a further calibration temperature can be programmed below CAL.2 , and with CAL.3 an
additional calibration temperature above CAL.2.

18 Communication interface for the PC
18.1 Communication interface USB
The oven is provided as standard with a USB-interface according to USB spezification.
Using this interface it is possible to control the oven from the PC and to produce reports. This is done
using the “Celsius“ 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. The default setting is ADDRESS 0.
Using this address each oven can be addressed by the PC and programmed.
If several ovens are connected by the USB interface to one PC, each oven requires a corresponding interface
on the PC as well as a separate cable.
The maximum cable length is 5 m.
For connection of the oven to the PC there is a USB connector on the back of the oven. The oven can be
connected to the PC using a A+B USB interface cable.
18.2 Bus interface RS485
When so ordered, the oven can be equipped at the factory with an RS485 interface instead of the USB
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” 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. Using this address each oven can be addressed by the PC
and programmed.
For this purpose the PC must be equipped with an RS485 interface or must be fitted with an RS232/RS485
converter. The cabling has to suit the individual location using a screened cable. The maximum total length
of the cable is 150 m.
A maximum of 16 devices can be addressed on the RS485 bus. A termination resistance of 220 Ohm has
to be connected to the last device.
18.3 Communication interface RS232C
The oven can be equipped as optional with a serial communication interface RS232C according to
Page 39
HPP page 39
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“ 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. The default setting is ADDRESS 0.
Using this address each oven can be addressed by the PC and programmed.
If several ovens are connected by the RS232C interface to one PC, each oven requires a corresponding
interface on the PC as well as a separate cable.
The maximum cable length is 15 m.
For connection of the oven to the PC there is a 9-pin connector on the back of the oven. The oven can be
connected to the PC using a screened interface cable. The screen has to be connected to the plug case. If
the serial interface is not being used, the cover supplied has to be fitted
Page 40
HPP page 40
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.
The size of the internal report memory is 1024kB. This corresponds to a memory capacity of approximately
6 months‘ continuous operation.
During ramp operation a larger amount of data are stored in the memory so that the maximum report
duration may be reduced.
If the power supply is interrupted, the instants of power failure and restoration of power are stored in the
controller.
19.1 Reading the report memory
Past report data can be printed either via the USB interface or by a PLC3-compatible printer connected to
the oven.
19.2 Reading the report memory into the PC via USB
Using the “Celsius“ program the record memory of the controller can be read via the RS232C interface into
a PC where it can be shown graphically, printed, and stored in memory.
Note:
The report memory of the controller is not altered or cleared by the reading procedure.
19.3 Printing the report memory from the climatic chamber
(see Section: „Printer“)
If the printer is not ready, e.g. cartridge empty or no paper, no report data are lost. Prints can be repeated
several times since the report memory is not cleared after printing.
The GLP data header is automatically included in the print-out: it contains the following information:
- Printing date
- Time period of report
- Running page number
- Serial number and oven designation
Page 41
HPP page 41
20 Memory card: MEMoryCard XL
A temperature programme with up to 40 ramps can be programmed on the MEMoryCard XL. Programming
can take place directly on the controller or through the PC program “Celsius”.
For improved clarity it is recommended that extensive programmes are prepared graphically on the PC.
Where a MEMoryCard XL is programmed, it can be read only on the same oven type for which it has been
programmed.
Marking:
The text field of the MEMoryCard XL can be marked individually with text or diagram.
20.1 Programming the MEMoryCard XL from the climatic chamber
Insert the MEMoryCard XL into the slot in the control panel field.
The selected settings are written directly to the card and stored on it. After the card has been removed, the
programme stored internally in the controller becomes again activated.
20.2 Programming the MEMoryCard XL from a PC with the climatic chamber
Link the PC to the oven with an interface cable via the serial interface (see Section: „Communication
interface“). Insert the MEMoryCard XL into the input slot in the control panel field.
Write protection:
The MEMoryCard XL can be provided with write protection using the PC program “Celsius”. The programme
on the card can then not be altered on the controller.
20.3 Programming the MEMoryCard XL from a PC using the read-write unit
Using a read-write unit (which can be purchased separately) the MEMoryCard XL can be programmed from
a PC with “Celsius” without any connection to an oven. It is important to ensure that the MEMoryCard XL
has to be inserted with the contact field pointing upwards towards the marking of the read-write unit.
Page 42
HPP page 42
Note:
The programme remains stored on the MEMoryCard XL after the card has been removed from the unit. It
can however be overwritten at any time by the PC using “Celsius”.
Details on programming the MEMoryCard XL with PC and „Celsius“ can be found in
the Celsius Operating Manual and in the Online Help.
20.4 Documentation on memory card MEMoryCard XL
The actual temperatures can be documented continuously on the memory card while the programme is
running from the chip card. After the programme has been completed they can be read and printed using
“Celsius”. The operation is described in the “Celsius” Operating Manual.
A certain amount of storage space is provided for documentation depending on the programme duration.
The sampling rate is set automatically by the controller depending on the programme duration.
With a programme duration up to 135 hours the documentation of the actual values on the MEMoryCard
XL takes place with a 1-minute cycle. With programmes of longer duration the sampling time is extended
up to 30 min max.
Documentation is started afresh on each programme start; the old report data are overwritten.

21 User-ID-Card (available as optional extra)
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-ID-Card card is inserted, the
SETUP
menu includes the additional item ID-LOCK. When the setting
is changed to ON, all changes to the oven are blocked after the chip card has been removed.
The blockage through the User-ID-Card is indicated by the illuminated key symbol on the control
panel.
Important:
If the oven is blocked through the User-ID-Card, there is no
programme operation with the MEMoryCard XL since that card could
be removed at any time and reprogrammed externally!

22 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.
A well-closing door is essential on an oven. On Memmert ovens, tight closure of the door is ensured by a
seal on the oven and another one on the door. In continuous operation the flexible sealing material may
take a permanent set. Readjustment may then be necessary in order to ensure proper closing of the door.
The top part (1) of the door hinge can, after releasing •
the 2 screws (2) at the top or bottom of the door, be
moved slightly in the direction of the arrow.
The door can be adjusted after releasing the socket •
screw (3) and rotating the excentric (4) by means of
a screwdriver. NOTE ! Screw (3) is locked with locking
varnish. It can be released by a sharp tug using a
hexagon socket key. Apply more locking varnish to
screw (3) and tighten it.
The closing panel (6) can also be adjusted in the direction of
the arrow after releasing the screw (5). It is important that the
panel is then screwed down firmly.
23 Cleaning
Regular cleaning of the easy-to-clean inside of the chamber prevents deposits which over time can
detract from the appearance and the functionality of the stainless steel chamber .
The metal surfaces of the oven can be cleaned with commercially available cleaning agents for stainless
steel. It is important to ensure that no rust-forming object comes into contact with the chamber or the
stainless steel casing. Rust deposits cause infection of the stainless steel.
If any contamination causes rust stains on the surfaces of the chamber, such spots must be cleaned off
immediately and the area polished.
The control panel, the plastic input modules and other plastic components of the oven must not be
cleaned using scouring cleaning agents or those containing solvents.

23.1 Cleaning HPP incubators
In order to ensure the proper function and long life of the Peltier cooling module it is essential to remove
any dust deposits from the heat sink on the back of the incubator (using vacuum cleaner, brush or bottle
brush depending on the amount of dust).
To assist with cleaning, the protective cover can be removed after releasing the screws.
