Transporting the dryer to its installation site 

 

 

 

 

 

Warning - lifting dryer contrary to instructions! 

Lifting the dryer contrary to instructions can cause damage.  

Lift the dryer only with the supplied lifting eyebolts! 

 

 

 

 

Transport lugs 

Transportation using lifting or forklift truck  

 

 

 

 

 

Warning against damage to property! 

The dryer is supplied upright on a pallet. Therefore always use a pallet 
truck or forklift truck to transport the dryer on the pallet. 

 

 

 

►  Secure the dryer on the lifting or forklift truck against sliding movements. 
►  Transport the dryer to its installation site. 

  

Installing and anchoring the dryer 

Requirements for the installation site  

The conditions at the installation site have a large influence on the functional 
capability of the dryer and the service life of the desiccant. In order to ensure a 
mode of operation, which is as continuous as possible, and low maintenance, the 
installation site must meet the following requirements:  

 

The installation location must provide protection against the weather inside a 
building as well as against humidity (e.g., the accumulation of condensation).  

 

The ambient temperature must not drop below +1 °C (33.8 °F). If necessary, 
an auxiliary heater is to be provided.  

 

Heed the dryer’s noise level when selecting the installation location (see 
Technical data  on page 66).
