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 and then remove the bottom panel (‘z’ in Fig. 4). For the Water heated and Ambient models only, the pressure plate (‘w’ in Fig. 4) must also be removed. 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: .” BSPT (CAB series) and .” BSPT (DAB series) and isolation valves (see ‘b’ in Fig. 5) should be fitted as close to the air curtain 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 bottom panel and intake grille assembly - see Fig. 4. The drain (see ‘d’ in Fig. 5) can also be accessed when the intake grille assembly and bottom panel are removed. Maximum water supply conditions are 125.C and 8 bar (0.8MPa). 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. Switch Panel Installation The backing box (standard double gang) should be rebated into a suitable wall. The box should be fitted so that the switch panel will be flush with the wall. Suitable conduit should be used where applicable to carry the cable between the heater and the switch. A CAT5 LAN cable with straight through connections should be use...
