Electrolux RCB 24 P Maintenance And Repair Manual page 3

EE | GENERAL DESCRIPTION
The THERMOSTABILIZER RCB42P is a refrigerating unit which is suitable for storing and transporting pre-
cooled blood products and medicinal products, such as vaccines etc..
Up to 30 bags of blood, each containing 500 ml, can be stored and transported in the cool box.
A thermoelectric unit (Peltier block) together with an electronic control unit keeps the temperature in the cool
box constant.
The thermoelectric unit is switched automatically from cooling to heating, depending on the ambient tem-
perature.
The cool box can be operated with either direct current (DC battery voltage) of 11 V to 42 V or alternating
current (AC supply voltage) of 90 V to 264 V, frequency 48 Hz to 62 Hz.
The insulation allows the temperature in the cool box to be kept constant for up to 8 hours when transpor-
ting or storing items without power supply at an ambient temperature of 25°C (77°F).
2 THE THERMOELECTRIC UNIT
The core of the thermoelectric unit is composed of two elements which operate according to the Peltier effect.
This effect is based on the connection of two different semiconductors. If direct current flows through the junc-
tion of these two conductors, heat or cold, depending on the direction of the current, is generated at this junc-
tion. By reversing the direction of the current (pole reversal), it is possible to switch from heating to cooling or
vice versa.
An electronic control unit measures the temperature in the cool box and controls the polarity and operating fac-
tor of the appliance. In this way the inside temperature of the appliance is kept constant between two set limits.
KER SAFETY INSTRUCTIONS
Please read this manual carefully before using the THERMOSTABILIZER. It contains important instructions
for the operational safety, use, maintenance and repair of the appliance. Keep the manual in a safe place for
future reference and make sure that it is retained with the appliance when the appliance is transferred to a
new location for owner, so that information about operation and safety regulations is available for every user.
Every user must be well acquainted with the operation of the appliance and with the instructions concerning
safety. Failure to observe these instructions can impair the performance of the appliance and cause dama-
ge.
@ The appliance may only be used by adults. Do not allow children to play with it or to tamper with the con-
trols.
© Do not use a damaged appliance. Any damage must be repaired before putting into operation.
@ Connection to the mains and installation are to be carried out in accordance with the operating instruc-
tions. Electrical connections must be compatible with the data on the type plate.
© The electrical safety of the appliance can only be guaranteed if the power supply earthing system has
been installed in accordance with the regulations.
© When disconnecting the electrical supply, eg plug - socket, always take hold of the plug - not the connec-
ting cable - to disconnect.
© If there is a malfunction, or before servicing or cleaning the appliance, switch off and disconnect from the
mains. Pull out the mains plug or, if this is inaccessible, disconnect the fuse.
@ Repairs to the appliance are only to be carried out by qualified persons.
@ Do not cover or block the appliance's vents. Make sure that air can flow freely through the vents.
