Important Note!
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
Always use gloves!
If the oven has to be carried, at least 2 persons are required to transport it.
Do not place the oven on a readily inflammable support surface!
It is important that the oven is set up accurately horizontally!

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•

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.

4.5 Note on EMC (electromagnetic compatibility)
This product is intended to operate on a supply network with a system impedance Zmax at the transfer
point (building connection) of 0.292 Ohm max. The user has to ensure that the product is only operated
on an electrical supply network which meets these requirements. If necessary, details of the system
impedance can be obtained from the local electricity supply authority.
Note:
Any work involving opening up the oven must only be carried out by a suitably qualified
electrician!
4.6 External connection
Equipment connected to the external connections must have interfaces which meet the requirements for
safe low voltage (e.g. PC, printer).
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.

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 oven is in standby mode. Heating and fan 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.

Further clockwise rotation selects the parameters (temperature setpoint etc.) as in operating mode I.
If no further settings (temperature setpoint etc.) are made for the ON phase, the controller accepts the
values from operating mode I.
For safety reasons, always check that an ON time has been programmed only during the required time
blocks and days.
Direct setting of the temperature setpoint:
When the controller is in stand-by mode or if the weekly programmer is in the ON phase, the temperature
setpoint can be selected directly by briefly pressing the SET key. Clockwise rotation then selects fan speed,
air flap and temperature monitor. Anticlockwise rotation again selects setting the individual time blocks.
