Construction and description

2.2 Description

The appliance can heat the working chamber up to 70 °C (IPP) or 45 °C (IPS) and cool it
down to 0 ºC (IPP) or 14 °C (IPS). 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). Condensation formation
during the cooling down process takes place outside the working chamber on the Peltier
element

Optionally, the appliance can be equipped with a light module.

2.3 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 to
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.

7.5 Adjustment

The appliances are temperature calibrated and adjusted at the factory. In case readjust­ment should be necessary later on – for example due to influence of the chamber load
– the appliance can be calibrated customer-specifically using three calibration tempera­tures of your choice:

► CAL1 Temperature calibration at low temperature
► CAL2 Temperature calibration at medium temperature
► CAL3 Temperature calibration at high temperature

For temperature adjustment, you will need a calibrated reference measuring device.

Maintenance and service

8. Maintenance and service

8.1 Cleaning

Warning!
Danger of injury by electric shock. Before any cleaning work,
pull out the mains plug.

Warning!
In case of appliances of a certain size, you can get accidentally
locked in, which is life-threatening. Do not climb into the appliance!

8.1.1 Working chamber and metal surfaces

Regular cleaning of the easy-to-clean working chamber prevents build up of material remains
that could impair the appearance and functionality of the stainless steel working chamber
over time.

The metal surfaces of the appliance can be cleaned with normal stainless steel cleaning
agents. Make sure that no rusty objects come into contact with the working chamber or with
the stainless steel housing. Rust deposits can lead to an infection of the stainless steel. If rust
spots should appear on the surface of the working chamber due to impurities, the affected
area must be immediately cleaned and polished.

8.1.2 Plastic parts

Do not clean the ControlCOCKPIT and other plastic parts of the appliance with caustic or
solvent-based cleaning agents.

8.1.3 Glass surfaces

Glass surfaces can be cleaned with a commercially available glass cleaner.

8.1.4 Peltier cooling module

In order to guarantee perfect
function and long lifetime of the
Peltier cooling modules, it is
absolutely essential that you
remove dust deposits from the
heat sink on the rear of the
appliance (with a vacuum
cleaner, paintbrush or bottle
brush, depending on the
amount).

To make cleaning easier, the
cover can be removed after the
screws have been loosened (Fig.

23).
