8.2.3 MAINTENANCE OF ROTATION REGENERATION EXCHANGER
The rotation exchanger is accessible through service doors. 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 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, cleaning and service work on the rotary heat exchanger, the power supply must be switched off and measures must be taken to
prevent the electric motor from being switched on during these works. The exchanger is accessible through front doors by turning the locks. As
part of the maintenance, it is necessary to check the tension of the drive belt, the rotor seal, the clogging of the rotor and the tension of the
circumferential casing of the split rotation heat exchanger. The device is cleaned with compressed air, steam or pressurized water. Cleaning must
be performed by trained personnel. Improper cleaning can seriously damage the rotor of the rotary heat exchanger. For split rotors, the
manufacturer of the rotation exchanger recommends light tightening of the circumferential casing after the first 80 hours of operation (performed
evenly around the entire circumference of the rotation exchanger - ATTENTION TO OVALITY !!!), including the adjustment of the sealing
elements.
8.2.4 PERIODIC INSPECTIONS
Perform periodic inspections at least once a year as part of a summer service inspection. It is optimal to carry out inspections twice a year, usually
before and after the end of the winter season.
During the regular service inspection it is necessary in particular:
–
–
–
–
Perform regular inspection and cleaning of the heat exchange surfaces of the exchangers
Clean or replace filter inserts in air filters
check the condition of the damping inserts, especially their tightness, and replace them in time
Perform inspections and checks of the function of electrical components (contactors contacts, tightening of terminals, condition of
insulation…)
Check the hinges and supports of the device
Carry out regular inspections of those facilities for which the applicable laws, decrees, standards and rules so require
Keep proper records and monitoring of the outcome of inspections and revisions and monitor the implementation of the measures taken
Check the siphons for condensate drainage, especially their permeability and tightness, especially the tightness of the mounting on the unit
and the tightness of the ball seating
