4 .13 Wall plate fixing:

1 . If installing the APU Midi on a wall ensure suitable fixings for the wall

structure are used and are suitable to support the unit when fully

filled with water (see technical section for filled weights) . The holes in the

wall plate are 6 mm ( section 10) in diameter, the maximum permissible screw

head height is 3 mm .

2 . All holes in the wall mounting plate must have fixings used in them as per

the image below, do not leave out fastenings as this will compromise the

integrity of the wall plate .

3 . Ensure you have sufficent room around the area you are mounting the APU

Midi to allow installation, servicing and operation . See section 2 .12 .

4 . Ensure wall plate is fixed to a flat vertical wall and the top of the plate is

horizontal .

5 . Retain the APU Midi to the wall mounting plate using the single M6

retaining screw at the top of the wall plate .

6 . Fit the plastic cover by pressing as indicated below with the palm of the

hand as until the Dual Lock

4 .14 Floor installation:

1 . If installed on a floor ensure the APU Midi is located so it cannot be kicked

or knocked over .

2 . Ensure the floor surface on which the APU Midi is located is flat and level .

3 . If possible locate the unit against a wall for added stability .

4 . If the APU Midi is located in an area that might be subjected to flooding,

mount the APU Midi on a raised plinth .

4 .15 Pipework connections & guidelines:

1 . Before connecting the APU Midi to the system ensure that system flushing

has been performed correctly and all foreign matter, including pipe scale,

has been removed .

Note: Foreign material from the system coming into contact with the

expansion vessel bladder could cause premature failure of the expansion

vessel .

2 . Isolating valves MUST be installed on the unit inlet and outlet, before

connection to the flexible hoses to allow the unit to be isolated if required .

The isolation valve on the outlet should be of a lockshield type .

See Fig . 12 .

3 . A drain valve must be fitted on the outlet of the APU Midi before the

isolation valve . See Fig . 12 .

4 . The connection to the heating/chilling system is also made with the

supplied flexible hose and a 15 mm compression fitting . The hose is made

water tight with a sealing washer on assembly, nip tight to 4 to 5 Nm

for water tight seal . (Do not overtighten) .

5 . The connection to the heating/chilling system can be made to the left or

right hand side by routing the flexible hose supplied as detailed below .
