Floor mounting
If there is no wall that is suitable for wall mounting, the HRC can also be placed on
a concrete floor using the optional Orcon base (article number: 22700080) for floor
mounting.
1. Place the legs in the recesses on the bottom of the unit (Figure A). This works best
when the unit is on its side.
2. If necessary, use a spirit level to adjust the levelling feet so that the unit is level on
the floor (Figure B).
4.6 Connecting ducts to the unit
Once the unit is fitted, the ducts can be mounted. The ducts (return) from and to
the home (supply) are on one side of the unit, and the ducts from and to the outside
are on the other side. In order to prevent condensation on the ducts from and to the
outside, these must always be insulated externally to ensure that they are damp-
proof. It is preferable to use preinsulated plastic ducts made of PE or PUR. Try to keep
these ducts as short as possible.
It is advisable to connect the ducts to and from the home to the unit using sound
dampers with a minimum length of 100 cm. When measuring the ducts, bear in mind
that not too much energy is lost when transporting the air through ducts that are
too narrow. It is preferable not to have the total resistance of both the supply system
and the discharge system exceed 100 Pascals. The supply duct system must be fitted
in such a way that NEN 1070, table 4 is complied with in the nominal setting. Think
of crosstalk and installation noise, also with underfloor ducts. Ensure that the supply
ducts are insulated if necessary, e.g. if they are installed outside the insulated skin.
Attention: make sure no residual material is able to reach the device while
installing the pipes to prevent it from damaging the device.
