6. WORKING CONDITIONS
The units must not be used when:
»
the air being transferred may contain solid, pasty, fibre and aggressive substances
causing corrosion or decomposition of zinc, copper, steel and aluminium;
»
temperature and humidity values for external air in summer or winter are outside
limits determined for Europe;
»
operation in maritime or tropical climate is expected;
»
the air is excessively dusted and involves very often replacement of air filters within
the unit;
»
power supply of water heating coil is unreliable for a long period of time that even
operable automatic equipment would not protect the exchangers against freezing
and possible resulting losses (damage to the heating coil, damages due to room
flooding).
