Waterbath cooling unit CDP 115

About this manual

Purpose and target group

This manual describes the construction, function, assembly and operation of CDP 115 Peltier
cooling units for MEMMERT waterbaths. It is intended for use by trained personnel of the
operator, who have the task of assembling and/or operating the unit.

If you as the operator are asked to work on the unit, you should read this manual carefully
before starting work on the unit. Familiarise yourself with the safety regulations. Only perform
the work that is described in this manual. If there is something you don't understand, or
certain information is missing, ask your superior or get in touch with the manufacturer. Do not
do anything without authorisation.

This manual cannot describe all the possible combinations of setup and connection
variations. To make matters clearer, the assembly of two representative waterbaths is
described; the depictions may therefore differ slightly from the actual appearance. But
the assembly always follows the same pattern.

Other documents that you must read:

You should also consult the instruction manual for the waterbath on which the cooling unit is
to be operated.

Storage and Forwarding

This instruction manual belongs with the unit and should always be stored so that persons
working on the unit have access to it. It is the responsibility of the operator to ensure that
persons who work on or who will work on the unit are informed as to the whereabouts of
this instruction manual. We recommend that it is always stored in a protected location close
to the cooling unit. Make sure that the instruction manual is not damaged by heat or damp.
If the cooling unit or the waterbath is sold or transported and then set up again at a different
location, this instruction manual must also go with it.

Warning!
After removing covers, current-carrying parts may be exposed.
You may get an electric shock if you touch these parts. Disconnect
the mains plug before removing any covers. Any work inside the
unit may only be performed by qualified electricians.

2.2 Function

The waterbath cooling unit CDP 115 makes it possible to cool the water in Memmert water­baths to temperatures below room temperature. To do this, water is pumped from the water­bath, cooled by a Peltier module and then returned to the waterbath (Fig. 2).

The cooling performance is constant and cannot be regulated. The temperature control of the
water is taken over by the waterbath; its controller automatically takes into account the cool­ing performance of the cooling unit.
