Maintenance Of Recuperation Plate Exchanger; Maintenance Of Regeneration Rotation - S&P DUOVENT MODULAR DV Instruction Manual

8.2.3 MAINTENANCE OF RECOVERY PLATE EXCHANGER
The heat recuperation exchanger is protected by filters and can therefore only be contaminated very lightly. Nevertheless, it is recommended to
perform a visual inspection every 5 years. If necessary, open the front door of the unit. Remove dust from the boards with a dry brush (not wire!)
Or by blowing with compressed air.
8.2.4 MAINTENANCE OF THE REGENERATION ROTATION EXCHANGER
The heat recovery exchanger is protected by filters and can therefore only be contaminated very lightly. Nevertheless, it is recommended to
perform a visual inspection every time the filters in the unit are replaced. It is forbidden to start or operate the rotary heat exchanger with the
inspection opening (door) open or the panels exposed. Before starting maintenance and service work on the rotary heat exchanger, the power
supply must be switched off and measures must be taken to prevent the regenerator electric motor from being switched on during service work.
To access the heat exchanger, open the service door on the operating side of the unit.
