Instruction book Safety precautions Safety icons Explanation Danger to life Warning Important note Safety precautions, general General precautions All responsibility for any damage or injury resulting from neglecting these precautions, or non-observance of the normal caution and care required for installation, operation, maintenance and repair, even if not expressly stated, will be disclaimed by the manufacturer.
Instruction book Safety precautions during installation Precautions during installation 1. The dryer must only be lifted using suitable equipment and in accordance with the applicable safety regulations. Loose or pivoting parts must be securely fastened before lifting. It is strictly forbidden to dwell or stay in the risk zone under a lifted load. Lifting acceleration and deceleration must be kept within safe limits.
Instruction book 17. If the maximum pressure of the compressor is higher than the design pressure of the dryer, a full flow safety valve must be installed between the compressor and the dryer in order to blow off the excessive pressure. This is done in case the safety valve of the dryer is out of order or blocked.
Instruction book atmospheric pressure shall be protected by a pressure relieving device or devices as required. 12. Yearly inspect the air receiver. Minimum wall thickness as specified in the instruction book must be respected. Local regulations remain applicable if they are more strict. Also consult following safety precautions: Safety precautions during installation Safety...
Instruction book 18. Make sure that all sound-damping material and vibration dampers, e.g. damping material on the bodywork, is in good condition. If damaged, replace with genuine material from the manufacturer to prevent the sound pressure level from increasing. 19. Never use caustic solvents which can damage materials of the air net, e.g. polycarbonate bowls.

Instruction book Disposal of other used material Used filters or any other used material (e.g. filter bags, filter media, desiccant, lubricants, cleaning rags, machine parts, etc.) must be disposed of in an environmentally friendly and safe manner, and in line with the local recommendations and environmental legislation. 2920 7111 23...
Instruction book General description General description Introduction The air dryers described in this book are heatless adsorption dryers, designed to remove humidity from compressed air for industrial applications. PH dryers are available in a version to reach a pressure dew point down to -20 °C (-4 °F) or down to -40 ˚C (-40 ˚F) and are equipped with a DC1 electronic controller.
Instruction book PH 230 – Main parts Reference Description Reference Description DC1 controller Silencer Right tower Air outlet Left tower Operation General With its simple construction, the air dryer is both reliable and easy to service. A dryer module basically consists of two towers, containing the adsorption material or desiccant. The desiccant is a very porous grain material, able to adsorb large amounts of water vapor.

Page 16
Instruction book After a preset period (or when triggered by the PDP sensor) the function of the towers is reversed. The fully regenerated tower will now dry the air, while the desiccant in the other tower will be regenerated. By default, the regeneration timer will restart from the beginning of the cycle in case of a power failure during operation or in case the dryer was switched off.

Instruction book Installation in case X2 is connected The entire flow from the compressor passes the dryer. The dry air is stored in the air receiver downstream of the dryer. With X2 connected, the dryer will stop the purge air flow at the end of the cycle. (< 2 minutes) and it will restart when the air compressor resumes to deliver compressed air.
Instruction book Electrical connections General The electrical wiring must comply with the local regulations. The air dryer must be earthed and protected by fuses against short-circuiting. Consult the electric diagram delivered with the dryer. Before switching on the main power supply, check the voltage requirements in the technical specifications or on the dryer’s data plate.
