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 used to connect the switch panel to the appliance PCB. Warning: Ensure cable is secure and the cable path does not come into contact with heater element or other moving parts. Test all switch settings once installation is complete. Electrically heated variants Operation using switch box - CABC5 Switch on electrical supply to the air curtain. Rotate the switch to the desired heat setting. Settings available are; OFF -Low Fan -Low Fan with Low Heat & High Fan -High Fan with Low Heat -High Fan with Full Heat The rocker (auto / manual) switch allows for manual over-ride of a door switch if fitted. Manual allows the appliance to run at the desire setting, while Auto provides an energy saving feature by shutting down the appliance while the door is closed. The unit should always be switched OFF using the switch box cont...
