Further important data on the dryer such as the details on the permissible operating pressure and the electrical connection are found on the type plate (for position of the type plate see page 8 ) KA-MT 1-8/D3...
Supplementary documents such as operating manuals for options or pertaining components must always be heeded. They contain additional information, e.g. regarding maintenance, and are therefore necessary for safe operation of the plant. * Planned dryers may be equipped with special components. KA-MT 1-8/D3...
These operating instructions must be continuously available at the site where the dryer is used. We recommend to prepare a copy and to keep the same in a safe and freely accessible place next to the dryer. Keep the original document in a safe place. KA-MT 1-8/D3...
◊ When fi lling drying agents, wear a dust mask and eye protection! ◊ If a spillage occurs, any spilt drying agent must be taken up immediately. There is a risk of skidding! KA-MT 1-8/D3...

When working at the oil indicator, always wear protective goggles. Skid risk When emptying and fi lling the vessels with drying agent, there is a risk of skidding caused by spilt drying agent. KA-MT 1-8/D3...
Inform the haulier immediately in writing of any damages. Contact the manufacturer urgently in order to report the damage. Warning! A damaged dryer must not be taken into operation! Damaged components may lead to functional faults and possibly cause further damage. KA-MT 1-8/D3...
The dryer should only be transported in an upright position. Note the weight of the dryer! Depending on its size, the dryer may weigh up to approx. 110 kg. Take this into account with regard to the following work steps! KA-MT 1-8/D3...

Retighten the screws securing the stand profi le and the muffl er. Use suitable attachment material of suffi cient carrying force to anchor the dryer to the wall. KA-MT 1-8/D3...
If you wish to take the dryer back into service after an extended period of sto- rage, please proceed as described for its fi rst commissioning and start-up (see page 26). Store drying agents Do not store drying agents in the open air. Protect drying agents against humidity. KA-MT 1-8/D3...
The stored humidity is then removed again from the drying agent and re-introduced into the ambient environment. To this end, the two chambers alternate between different operating modes. Whilst in one vessel, compressed air is de-humidifi ed (adsorption), in the other vessel the humid drying KA-MT 1-8/D3...

The humidity stored in the drying agent is taken up by the air fl ow and expelled into atmosphere via the muffl er. Regeneration in in the right drying agent chamber KA-MT 1-8/D3...
Page 18
When the drying agent in the adsorbing chamber has taken up a suffi cient level of humidity, then the switchover between the vessels will be effected between the vessels. Following switchover, the above-described process is repeated, with the adsorption and regeneration now taking place in the respective different vessel. KA-MT 1-8/D3...
This replacement optimizes the regeneration air consumption and therefore restores the energy effi ciency of the dryer. To receive more information on this conversion, please contact the manufacturer. KA-MT 1-8/D3...
The data required to meet these preconditions are contained in the technical documentation attached in the annex. Warning! If the above preconditions are not complied with, a safe operation of the dryer cannot be assured. Also, the functionality of the dryer may be detrimentally affected. KA-MT 1-8/D3...
If you fi t a bypass line (8) with additional shutdown valve: Fit the line such that, when carrying out maintenance work on the dryer, the line system can continue to be supplied with compressed air. KA-MT 1-8/D3...
Fit terminal block into the connector and use bolt to remount the connector with seal on the switchbox. In all phases the dryer must be protected against short circuits by means of fuses. In order to relief cable strain, re-tighten the PG union. KA-MT 1-8/D3...
