Electrical The installation of this appliance should be carried out by a competent electrician and be in accordance with the current IEE wiring regulations. 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. 4A & 4B. If the unit is to be operated in conjunction with a door switch, a normally open switch should be wired as per ‘D’ in Fig. 8 & 9 as appropriate. Note: If using a door switch, an additional 2 core (low voltage) cable is required between the door switch and the air curtains. If the unit is to be connected to a Building Energy Management System, connections are made as per ‘S0, S1, & S2’ in Fig. 8 & 9 as appropriate. 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. 3) are: ½” BSPT (CAB series) and isolation valves (see ‘b’ in Fig. 3) should be fitted as close to the air curtain connection points as possible. For commissioning, air bleed valves (see ‘c’ in Fig. 3) are fitted to the coil, which can be accessed by removal of the ceiling tile - see Fig. 2. Thermostatic control A capillary type thermostat is factory fitted within the unit, as per ‘C’ in Fig. 8, giving a selection scale of 0-40ºC. When the thermostat operates, the power output will reduce depending on the switch setting. - Fan only - No effect - Half Heat - Heater will reduce to Fan only - Full Heat - Heater will reduce to Half Heat To override the thermostat, first Isolate the supply to the heater. Remove the connection on terminal ‘1’ of the thermostat and reconnect it onto the piggy back connection on terminal ‘C’. Door switch control (Electric models) By including a door switch in the circuit (as per ‘D’ in Fig. 8) the air curtain will respond to door openings as follows: (1) (2) Maximum water supply conditions are 125ºC 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. (3) (4) (5) If the door re-opens during this 3 minute run on cycle, the process will restart at (1). Switch Panel Installation The backing box (standard double gang) should be surface mounted onto a suitable wall, alternatively a recessed box can be used (not supplied). Suitable conduit should be used where applicable to carry the cable between the heater and the switch. A CAT5 computer network 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. Note: If using a door switch, an additional 2 core (low voltage) cable is required between the door switch and the air curtains. 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 desired 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 control, and not by mains power supply interruption. When the unit is switched off (via the switch box) the fan will run on for 1 minute without heat to discharge any residual energy from the heating elements. When first turned on the control will run through a system check. The selected settings will be reached and maintained after a 30 second period. Door opening will energise the air curtain at the set conditions (switch box settings). On door closure operation will continue at the set conditions for a further 1 minute. Between 1 minute and 2 minutes from door closure, set back operation, ½ heat (if heat selected) and ½ fan will activate. Between 2 minutes and 3 minutes, the fan only (½ speed) shut down cycle will be engaged. After 3 minutes, the air curtain will return to a dormant state until the door is re-opened. Thermal Safety cut outs The power supply to the heating elements will be interrupted if one or a combination of the following abnormal events occur: 1. Air inlet or outlet grilles are obstructed. 2. Internal ventilation is impaired due to build up of dust and fluff. 3. Blower unit stalls. Before resetting the thermal safety cut-outs you must turn the power OFF. Unlock the grille by moving the two sliders into the open position ‘x’ as shown in Fig. 2A, using a small screw driveror other suitable tool. With the grille partially open disconnect the safety cord to allow the grille to fully open. Then access the reset buttons as shown in ‘y’ in Fig. 2B. Before re-setting the reason for activation must be determined and corrective action taken.
