d) Check of V-belt tension and wear (as needed).
e) Regular check of input filters (min. once a month) - if the heater is equipped with
them or they are in the air-conditioning line with the heater. When clogged, clean
them or replace the filter cloth. Filter clogging time depends on the intake air
pollution. Clogging of the filters significantly reduces the amount of air supplied by
the heater and increases the temperature of the heat exchanger chamber. The heat
exchanger may be overheated and thus its service life may be reduced.
f) Lubrication of fan bearings - applies only to some fans, e.g. fans with bearings for
high temperatures (of ADH-RDH K / K2 type).
Note: for MTP (MTPAL) standard sets, maintenance-free bearings with permanent
grease filling are used.
Defects:
a) Overheating of heat exchanger, failure of safety thermostat T1
- check whether the suction and discharge spaces (piping, ...) are passable
- check fan condition, loose V-belts, seized bearings
- check the filter cloth, or also filter inserts
- if the filters are not clogged, it is necessary to consult the defect with the
production plant.
b) Flue gases flow into the heated space or higher oxygen content is measured in flue
gases
- check bolt tightening of the tube plate cover and the burner flange.
- replace the seal of the burner flange and the tube plate cover.
- check whether the combustion chamber is not burned.
