2.3 Overview of the safety instructions
Certified skilled personnel
Installation works must exclusively be carried out by authorised and qualified skilled personnel. Prior to
undertaking any measures on the DRYPOINT®RAX 20-500 NA UL compressed-air refrigeration dryer,
the certified skilled personnel shall read up on the device by carefully studying the operating instructions.
The operator is responsible for the adherence to these provisions. The respective directives in force apply
to the qualification and expertise of the certified skilled personnel.
For safe operation, the device must only be installed and operated in accordance with the indications in
the operating instructions. In addition, the national and operational statutory provisions and safety
regulations, as well as the accident prevention regulations required for the respective case of application,
need to be observed during employment. This applies accordingly when accessories are used.
Danger!
Compressed air!
Risk of serious injury or death through contact with quickly or suddenly escaping compressed air
or through bursting and/or unsecured plant components.
Compressed air is a highly dangerous energy source.
Never work on the dryer when the system is under pressure.
Never direct the compressed-air outlet or condensate drain hoses at persons.
The user is responsible for the proper installation of the dryer. Non-observance of the instructions in the
"Installation" chapter leads to the expiration of the guarantee. Improper installation may result in
dangerous situations for the personnel and/or the device.

Danger!
Supply voltage!
Contact with non-insulated parts carrying supply voltage involves the risk of an electric shock
resulting in injuries and death.
Only qualified and skilled personnel are authorised to run electrically-operated devices. Prior to
undertaking maintenance measures at the device, the following requirements must be met:
Make sure that the power supply is switched off and that the device is off and marked for maintenance
measures. Please also ensure that the power supply cannot be re-established during the works.

Caution!
Refrigerant!
The compressed-air refrigeration dryer uses HFC-containing refrigerants as a coolant.
Please observe the corresponding paragraph entitled "Maintenance works at the refrigeration cycle".
Warning!
Refrigerant leak!
A refrigerant leak involves the danger of serious injury and damage to the environment.

Safety instructions
DRYPOINT® RAX 20-500 NA 1ph UL 9
The DRYPOINT®RAX 20-500 NA UL 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 name plate as regards the type and amount of refrigerant.
Comply with the following protective measures and rules of conduct:
1. 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.
2. 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.
3. Prior to carrying out works on refrigerant-carrying parts, remove the refrigerant to such an extent that
safe working is possible.
4. Do not eat, drink or smoke during work. Keep out of the reach of children.
5. Breathing protection: ambient-air-independent respirator (at high concentrations).
6. Eye protection: sealing goggles.
7. Hand protection: protective gloves (e.g. made of leather).
8. Personal protection: protective clothing.
9. 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 personnel3.
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.

grounded in the respective provisions and laws and capable of carrying out the required works and of identifying and avoiding any
risks during the machine transport, installation, operation and maintenance.

Note!
Contaminated intake air!
In the event that the intake air is strongly contaminated (ISO 8573.1 class 3.-3 or poorer quality), we
recommend the additional installation of a prefilter (e.g. CLEARPOINT F040), to avoid clogging of the
heat exchanger.
Caution!
Heating-up through fire!
In the event of a heating-up through fire, the containers and pipes of the refrigerant system can
burst.
In this case, please proceed as follows:
Switch off the refrigeration plant.
Switch off the mechanical ventilation of the machinery compartment.
Use ambient-air-independent respirators.
Containers and plants which are filled with refrigerant can burst violently in the event of fire.
The refrigerants themselves are incombustible, but they are degraded to very toxic products at high
temperatures.
Remove the container/plant from the fire zone, as there is the risk of bursting!
Cool down containers and bottles via a directed water jet from a safe position.
In the event of fire, please use an approved fire extinguisher. Water is not a suitable agent to extinguish
an electrical fire.
This must only be carried out by persons who are trained and informed about the hazards emanating
from the product.
Caution!
Unauthorised intervention!
Unauthorised interventions may endanger persons and plants and lead to malfunction.
Unauthorised interventions, modification and abuse of the pressure devices are prohibited.
The removal of sealings and leadings at safety devices is prohibited.
Operators of the devices must observe the local and national pressure equipment regulations in the
country of installation.

Note!
Ambient conditions!
In the event that the dryer is not installed under suitable ambient conditions, the ability of the device to
condense refrigerant gas is impaired. This can result in a higher load of the refrigerating compressor, and
in a loss of efficiency and performance of the dryer.
This in turn leads to overheated condenser fan motors, to malfunction of electric components and to a
breakdown of the dryer. Failures of this type will affect warranty considerations.
Do not install the dryer in an environment in which chemicals with a corrosive effect, explosive gases,
toxic gases, evaporation heat, high ambient temperatures or extreme dust and dirt can be found.
