• Before any kind of work on the dryer make sure that it is depressurized (additional to
dryer this also refers to nearest upstream and downstream part of installation) and
disconnected from power supply.
• Do not exceed maximum operating pressure or operating temperature range (see
dryer and vessel type plate; Picture 1).
• The permissible working temperatures and pressures for the adsorption dryer add-on
parts are given under Technical data for those add-ons. Maximum temperature and
pressure for assembled system is the lowest of any individual part.
• It is necessary to ensure that the adsorption dryer is equipped with the corresponding
safety and test devices to prevent the permissible operating parameters from being
exceeded.
• Ensure that the adsorption dryer is not subject to vibrations that could cause fatigue
fractures.
• Adsorption dryer is not to be subjected to mechanical stresses.
• The medium used may not have any corrosive components that could attack the
materials of the adsorption dryer in a way that is not permitted. Do not use the
adsorption dryer in hazardous areas with potentially explosive atmospheres.
• All installation and maintenance work on the adsorption dryer may only be carried out
by trained and experienced specialists.
• It is forbidden to carry out any kind of work on the adsorption dryer, including welding
and constructional changes, etc.
• Depressurize the system before carrying out the installation work.
• Wear respiratory protective equipment when working with the molecular sieve.
Molecular sieve is a crumbling material that is producing fine dust which can cause
respiratory complications if inhaled in sufficient quantities.
• Ensure that the molecular sieve does not come into contact with the liquid water.
Unused molecular sieve in liquid water produces thermal energy that can cause the
water to boil and can inflict serious burns.
• At manipulation with adsorbent some amount of adsorbent can stay on the floor. In
case of adsorbent on the floor be extremely careful and immediately clean the floor to
prevent injuries due to fall on slippery surface.
• Ensure that adsorption dryer is installed as specified and without any stresses.
• Use original spare parts only.
