2 .11 Location: The preferred APU Midi location is either on a solid wall
or on a smooth level floor, both of sufficient strength to support
the filled weight of the unit, close to the water source and a
suitable overflow position (see Section 10 - Technical
Specification for filled weight) . The APU Midi must not be installed
in a loft space . It must also be considered that the noise and
vibration from the APU Midi may be transmitted through the
structure it is sited on . Ensure the minimum clearance
requirements are followed to allow servicing of the unit .
2 .12
Access and minimum clearance requirements: For emergencies
and maintenance the APU Midi must be easily accessible and have
the minimum clearance around it as laid out in Fig . 2 . Additional
access to the front of the unit will be required to operate the
keypad and view the display .
2 .13 Protection: The APU Midi must be located in a dry, frost free area .
Ventilation: Ensure an adequate air flow to cool the APU Midi .
2 .14
Separate the APU Midi from other appliances that generate heat .
Do not block the vent holes on the front cover or the air inlet at
the rear .
2 .15 Water retention: Site the APU Midi in a location where in the
unlikely event of a water leak, any spillage is contained or
routed to avoid electrics or areas sensitive to water damage .
As part of the AB airgap (CAT 5 fluid isolation) the APU has a weir
type overflow on the right hand side, water will be discharged from
this area in the event of the failure of the inlet valve or non-return
valves .
2 .16 Supply inlet pressure: The water supply inlet pressure must not
exceed 7 bar .
2 .17 Ambient temperature: The APU Midi must be sited in a location where
the ambient temperature does not drop below 4 °C or exceed 40 °C .

2 .18 Pipework: For optimum performance inlet and outlet pipework must be a
minimum of 15 mm pipe .
2 .19 Static outlet pressure: The static outlet head must be 3 metres below pump
maximum cold fill pressure (vertically above the appliance) .
2 .20 Noise: A flexible hose is supplied as standard which will minimise the
transmission of noise and vibration from the APU Midi pump to the pipework
connected to the appliance outlet . However, care must be taken when
mounting the APU Midi that any noise is not amplified through loose panels or
pipework .
2 .21 Flexible hose: Only use the ADEY hoses supplied with the APU Midi .
2 .22 Isolating valves: Separate system isolating valves (non-restrictive) must be
fitted to allow easy service of the APU Midi . Isolating valves must be mounted
where specified to allow the system isolation and removal of the APU Midi
if needed . See Section 4 .15 for installation details .
