Electrical Shock and Fire Hazards 
To prevent reduced safety protection or unwanted fusing, ALWAYS ensure 
that the code on the fuse cap matches the information printed next to the 
fuse holders. 
Spills 
Any spills in the sample compartment should be wiped up immediately. Any liquid 
spilled into the cuvette positions drains out through the drain tube located on the 
bottom of the module. It is recommended that an additional length of PTFE tubing 
is slid over the 6 mm OD drain tubing and inserted into a collection vessel to avoid 
liquid spilling onto the bench.  
The drain outlet tubing and vessel should be checked regularly for kinks in the 
tubing, blockages, or a full vessel. 
The exterior surfaces of the instrument should be kept clean. All cleaning should be 
done with a soft cloth. If necessary, this cloth can be dampened with water or a 
mild detergent. Do not use organic solvents or abrasive cleaning agents. 
The RESPONSIBLE BODY shall ensure that: 
a) appropriate decontamination is carried out if hazardous material is spilled onto 
or into the equipment; 
b) no decontamination or cleaning agents are used which could cause a HAZARD 
as a result of a reaction with parts of the equipment or with material contained in it; 
c) the manufacturer or his agent is consulted if there is any doubt about the 
compatibility of decontamination or cleaning agents with parts of the equipment or 
with material contained in it.
