2.0 INTRODUCTION
This wall mounted range of units is designed to provide mechanical
supply and extract ventilation with heat recovery.
The unit is fitted with two independent fans. Each fan has full speed
control for background and boost ventilation rates. To recover heat
from the extract air the heat exchanger block is utilised. The heat
exchanger can recover up to 95% of the normally wasted heat.
3.0 MECHANICAL INSTALLATION
Installation must be carried out by competent personnel in accordance
with the appropriate authority and conforming to all statutory
governing regulations. All mains wiring must be in accordance with the
current I.E.E. Regulations, or the appropriate standards. Ensure that the
mains supply (Voltage, Frequency and Phase) complies with the rating
label.
Please note a clear working space is required around the installed unit
to allow the cover to be removed and provide sufficient access for
maintenance such as filter change.
Please allow a minimum of 360mm in front of a HRXE-HERA unit.
The fan must be installed indoors, on a suitable wall away from direct
sources of frost, heat and water spray or moisture generation. For a
vibration-free result the unit must be mounted to a solid wall.
The unit must remain switched on at all times to maintain
ventilation within the dwelling. Turning the unit off will cause
long term damage to the unit and building fabric.

•
If fitting the mVHR in conjunction with a HRXe-HeRA-AV the
hanging brackets supplied with the mVHR are redundant and should
not be used. The installation instructions supplied with HRXe-HeRA-AV
should be followed.
The unit is designed for wall mounting, only on a solid wall. A
gypsum block or stud/plasterboard wall will not suffice.
•
One part of the mounting bracket (supplied) should be offered up
to the wall, ensuring it's located horizontally. mark the fixing points
through the pre drilled holes in the bracket and install with screws (by
others), whilst ensuring the interlock side is at the top (Figure 3).
•
Install the unit on the wall by ensuring the bracket fixed to the rear
of the unit interlocks over the wall mounted bracket (Figure 4).
Care must be taken to ensure the unit is installed true in all 3
dimensions. Failure to do so may result in overflow from the
internal condensation drip tray.
