Safety instructions 

iDRY iRDP CT 20-500 

 

 

 

Warning! 

Refrigerant leak! 

A refrigerant leak involves the danger of serious injury and damage to the environment. 

 

 

 

 

The iDRY iRDP CT 20-500 compressed-air refrigeration dryer contains fluorinated greenhouse 
gas/refrigerant. 
Installation, repair and maintenance works at the refrigeration system must only be carried out by 
certified skilled personnel (specialists). A certification in accordance with EC regulation 303/2008 must 
be available. 
The requirements of the EC 842/2006 directive must be met under all circumstances. 
Please refer to the indications on the type plate as regards the type and amount of refrigerant. 

Comply with the following protective measures and rules of conduct: 

 

Storage:

 Keep the container tightly closed. Keep it in a cool and dry place. Protect it against heat 

and direct sunlight. Keep it away from ignition sources. 

 

Handling:

 Take measures against electrostatic charging. Ensure good ventilation/suction at the 

workplace. Check fittings, connections and ducts for tightness. Do not inhale the gas. Avoid contact 
with the eyes or the skin.  

  Prior to carrying out works on refrigerant-carrying parts, remove the refrigerant to such an extent 

that safe working is possible. 

 

Do not eat, drink or smoke during work. Keep out of the reach of children. 

 

Breathing protection:

 ambient-air-independent respirator (at high concentrations). 

 

Eye protection:

 sealing goggles. 

 

Hand protection:

 protective gloves (e.g. made of leather). 

 

Personal protection:

 protective clothing. 

 

Skin protection:

 use protective cream. 

In addition, the safety data sheet for the refrigerant needs to be observed!

 

 

Caution! 

Hot surfaces!  

During operation, several components can reach surface temperatures of more than 140°F 
(60°C). There is the risk of burns. 

 

All components concerned are installed inside of the closed housing. The housing must only be 
opened by certified skilled personnel

Caution! 

Improper use!

 

 

 

The device is intended for the separation of water in compressed air. The dried air cannot be used for 
breathing-air purposes and is not suitable for the direct contact with food. 

This dryer is not suitable for the treatment of contaminated air or of air containing solids.
