7 Heat recovery section, rotating
7.1 Operating conditions
•
The operating temperature range is -40 °C ... +40 °C.
•
The maximum permitted pressure drop is 250 Pa.
• The pressure differences between supply and exhaust air must be designed to be as small as possible.
Large pressure differences lead to larger leaks.
7.2 Safety
WARNING
Observe general and section-specific safety instructions
7.3 Commissioning
• The units should not be started during the construction phase. If this cannot be avoided, the fan must
not be used without the heat exchanger in operation. Make sure that the filters are in place.
• Make sure that the supply or exhaust ducts are free from foreign objects that could damage the faces
of the heat exchanger.
•
Use a spirit level on the face of the heat exchanger to ensure that the rotor is upright.
• Make sure that the rotor rotates freely.
•
Make sure that the rotor belt is suitably tight and running freely in its proper place.
• Make sure that the brush seals on the circumference touch the surface of the arch plate. Also check
that the brush seals on the lower surface of the rotor mid-beams touch the surface of the exchanger.
•
Make sure that the access door gaskets are in place and intact. Close the access door and make sure
that each latch tightens properly.
• Go through the section-specific instructions, check that the access doors are shut, and then start the
unit.
• Check the functioning of the rotor after two weeks of use.
