2 Installation
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 21)
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.
2.1 Subframe (accessory)
2.1 Subframe (accessory)
Models 108, 153 and 246 can be placed on a subframe.
2.2 Stackable version (accessory)
2.2 Stackable version (accessory)
Two ovens of the same model size can be stacked on each other.
Foot locators have to be fitted on the bottom oven.
Mounting:
•
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
WARNING! Always pull out the supply plug before

2.3 Initial start-up
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).
2.4 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).

Within this range, any combination of temperature and humidity is possible without any appreciable
condensation.
Range B:

At low temperatures and low relative humidity, the usable range depends largely on ambient temperature
and humidity. In order to be able to use the range of low temperatures and low relative humidity the unit
has to be set up in a cool and dry room.

3.3 Material quality
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.

(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
Any work involving opening up the oven must only be carried out by a suitably qualified
electrician!
3.6 External connection
Equipment connected to the external connections must have interfaces which meet the requirements for
safe low voltage (e.g. PC, printer).
3.7 Water connection
The water container supplied has to be filled with distilled water and connected to the H2O connection
using the hose supplied.
For steam generation, use only:
•
Steam-distilled water (aqua dest)
or
•
Demineralised water (aqua dem) in accordance with VDE 0510/DIN EN 50272; regulations must be
strictly adhered to (production conductivity ≤ 10 µS/cm). Battery water in accordance with VDE 0510 is
available in larger chemist‘s shops, super markets, hardware stores and in the wholesale trade. The standard
VDE 0510/DIN EN 50272 has to be explicitly specified on the label. Otherwise, possible calcification in the
steam generators, steam piping and peristaltic pumps could affect the operability of the device.
Use only water with a pH value of > 5 and < 7.

4 Oven construction and operation
4 Oven construction and operation
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).

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

NEXT
Follow-on with next programme segment.
SPWT (T)
SET-POINT WAIT (temperature)
Wait until the setpoint temperature is reached.
The unit only starts the next programme segment when the programmed
setpoint temperature has been reached, even if the programmed
heating time has already elapsed.
SPWT (H)
SET-POINT WAIT (humidity)
Wait until set humidity is reached.
The unit starts with the next programme segment only when the
programmed humidity setpoint has been reached, even if the
programmed heating time has already elapsed.
SPWT (TH)
SET-POINT WAIT (temperature
and humidity)
Wait until set temperature and set humidity are reached.
The unit starts with the next programme segment only when the
programmed temperature setpoint and the programmed humidity
setpoint have been reached, even if the programmed heating time has
already elapsed.
