(1)

Fixing Positions

This appliance may be either wall-mounted or fixed to a ceiling - see Fig. 3 for

various fixing positions and ‘Mounting’ sections below, for  fixing details. A mini-

mum distance of 100mm is required from top of the appliance to ceiling (see ‘a’ in

Fig. 1) and also the distance between the bottom of the appliance and the top of the

door should be kept to a  minimum (see ‘b’ in Fig. 1).

Wall Mounting

Using the wall mounting bracket as a guide (see Fig. 2) mark off hole positions on

the wall (a minimum height of 2.0 metres is required from the floor level to the

bottom of the bracket).  Position the bracket such that the air outlet of the installed

air barriers will be as close to the top of the doorway as possible but will remain

unobstructed when installation is complete.

Solid brick or concrete block walls must be drilled and plugged (using a spirit level as

a guide - see ‘x’ in Fig. 2 - to ensure the bracket is level) with rawlplug No. 8 size fibre

inserts.  The plug must be located in the solid part of the wall and not just in the

plaster layer.

When fixing to ‘panel’ walls, the wall bracket should be attached to the stud-work

using No. 8 wood screws or by an alternative, equally secure method of fixing.

Once the wall bracket has been fitted, the air barrier can be clipped in place as

shown in Fig. 3a.

Ceiling Mounting

By using threaded inserts in the top panel of the air barrier, attachment to a ceiling

over the product can be achieved using suitable M8 threaded steel rod or similar

supports of sufficient strength - see Fig. 3b.

Electrical connection

All products are fitted with a microprocessor control. Electrical power and control

connections are made as shown in Fig. 6. A suitable local isolating switch must be

provided in the electrical supply circuit with at least 3mm clearance on each pole.

In order to access the electrical connections, remove the outlet grilles (‘x’, and ‘y’

in Fig. 4) by releasing the quick release fasteners and hinging the mouldings as

shown. Remove the bottom panel (‘z’ in Fig. 4) and also remove the pressure plate

(‘w’ in Fig. 4).

All Electric Models

 - Having removed a ‘knock out’ in the top panel, feed an

appropriate supply cable (see ‘a’ in Fig. 6A)  through a suitable cable gland (not

supplied) fitted in the top panel and attach to the terminal block (see ‘b’ in Fig. 6A).

All Water heated and Ambient Models

  - Having removed a 'knock out'

in the top panel, feed an appropriate supply cable (see 'a' in Fig. 6B) through a

suitable cable gland (not supplied) fitted in the top panel and attach to the PCB (see

'b' in Fig. 6B).

All Models

  - A suitable cable (CAT5 or equivalent) for a switch panel (kit ref. -

CABC5 for electrically heated models or CABC6 for water heated/ambient models)

can be similarly introduced through the top panel and plugged into the circuit board

as shown in Fig. 6A & 6B. If the unit is to be operated in conjunction with a door

switch, a normally open switch should be wired as per Fig. 7 & 8 as appropriate.

Note: If using a door switch, an additional 2 core (low Voltage) cable is required

between the door switch and the air barriers.

If the unit is to be connected to a Building Energy Management System, connections

are made as per Fig. 7 & 8 as appropriate. Ensure that the air curtain is securely

fastened in position and that the supply cables are firmly clamped before operating

the appliance.

Water connection

Models designed for use in conjunction with a low pressure hot water supply should

be individually connected  (in a parallel circuit) to the flow and return pipe-work.

Connections (see ‘a’ in Fig. 5) are: ½ “BSPT (CAB series) and ¾” BSPT (DAB series)

and isolation valves (see ‘b’ in Fig. 5) should be fitted as close to the air barrier

connection points as possible.  For commissioning, air bleed valves (see ‘c’ in Fig.

5) are fitted to the coil, which can be accessed by removal of the lower panel and

intake grille - see Fig. 4. The drain (see ‘d’ in Fig. 5) can also be accessed when the

grille and lower panel is removed.

Maximum water supply conditions are 125ºC and 8 bar.

To aid installation, the water coil connections may be moved to either side of the

appliance. By removing the water coil and appropriate knockouts the water coil can

then be re-inserted into the required orientation. This procedure should be carried out

before mounting the appliance.
