a) The unit must be installed outside in a well ventilated area.
b) The unit must not be installed near the following:
sources of heat.
combustible materials.
return/air intake of an adjacent building.
c) It is necessary to ensure that adequate clearance around the unit is provided (Fig. 16).
d) The installation must be as simple as possible to aid maintenance.
e) The unit must be fixed on a hard base and must be protected from risks of flooding.
f) We recommend that the apparatus be raised 100 mm off the ground using blocks in order to connect a
condensate drain pipe (as required).
g) Use the anti-vibration mountings supplied (within the removable panel). Ensure these are not
overcompressed when tightening and that a minimum amount of bolt shows after fitting (approx.12mm)
h) The blown air must not be directed towards surrounding windows.
i) Vibrations and noise must not be transmitted to any nearby buildings.
j) Avoid siting the unit in any area where there is a possibility of the fan guards becoming blocked, eg.
under or near to deciduous trees. Ensure there is adequate ventilation around the unit to avoid the airflow
being restricted. Consider the potential for problems caused by corrosive atmospheres, other extractor
fans nearby and any area where strong winds may impair the performance of the unit.
k) Noise levels should also be considered when siting the unit. Your Local Authority may enforce a
maximum permissible noise level, measured at neighbouring properties. For information on calculation
maximum or permissible noise levels, please call Baxi on 0844 871 1568.
l) The outdoor sensor must be fitted to a north facing wall.
5.2 Guarding
1. This unit contains electrical components and moving parts.
These components, and the surrounding system pipework, operate at high temperatures. Where young
children or animals are concerned, Baxi recommend a barrier or guard to avoid tampering. The guard
must be of a suitable design and not restrict the air flow through the unit. A risk assessment MUST be
carried out prior to installing the unit.
NOTE: A guard is available from Baxi as an accessory if required.
Part number 5134518 – Guard Ambiflo™ 75 & 90.
Part number 5134519 – Guard Ambiflo™ 105.
2. See Fig. 16 for the orientation of the guard and please refer to the separate instructions for fixing details
and clearances required.
