2 LOCATION - GENERAL

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 .
