1 Safety 

information 

1.1 

General safety information 

 
The PTT Peltier Thermostating Unit cools or heats tempering liquids and sample liquids. Hazards arise 
from this due to high or low temperatures, fire and the general hazards due to the application of electri-
cal energy. 
The user is extensively protected by the application of the relevant standards. Further hazard sources 
can arise from the type of material for which the temperature is to be stabilised, e.g. by exceeding or 
undercutting certain temperature thresholds or with the fracture of the sample liquid container and reac-
tion with the tempering liquid. 
 
It is not feasible to include all possible situations. They remain essentially subject to the judgement and 
responsibility of the operator. 
 
The device may only be used as intended, that is as described in these operating instructions. This in-
cludes operation by instructed specialist personnel. 
The device conforms to the EMC standard DIN EN 61326-1 Class A. 
 
The device is not designed for use under medical conditions according to DIN EN 60601-1 or
