CAUTION
Risk of injury due to corrosive condensates
Condensates are often corrosive. The hoses can contain
condensate residue. These materials can flow out when the
hose connections are opened.
• Take appropriate measures where needed to collect
residual condensates.
• Appropriate precautions should be taken, and relevant
regulations on disposal should be complied with.
NOTICE
Damage to components!
The hoses on the peristaltic pumps should never be
lubricated.
