INSPECTION The frequency of the cleaning schedule is dependent upon the environment the air curtain has been installed into. As a minimum Dimplex recommend a weekly inspection to ensure that there is no signifi cant build-up of dust or dirt reducing the performance of the air curtain and causing nuisance smell. Upon inspection, if any foreign objects are encountered which may cause damage to the fan, impellors or elements they must be removed. The external appearance of the air curtain can be maintained by wiping occasionally with a damp cloth. For stain removal, a weak soap solution can be applied with a cloth and the surface wiped dry. Care must be taken to avoid any moisture ingress into the product.

1. The inside of the air curtain must be cleaned at a minimum interval of once every 3 months, or

more frequently if the weekly inspection deems it necessary. To clean the product remove the inlet grills by doing the following: a. Using a fl at head screwdriver, loosen both outlet grill screws to remove the grill (‘x’ in Fig. 4) b. Using a Philips head screwdriver, remove the three M4 screws to remove the bottom panel (‘z’ in Fig. 4) c. Locate and remove the two M4 screws located behind the inlet grills on the lower left and right hand sides (fi xed to the end caps) d. Rotate and remove the inlet grill to expose the heating elements

2. Once the heater bank has been accessed the unit can be cleaned using a vacuum cleaner with

a brush attachment being careful not to disturb or damage the internal wiring or thermal cut- outs. When the element bank has been cleaned, the inlet grill must be replaced before the air curtain is turned back on.

3. Please note that the motors do not require any additional lubrication.8

Models Electrical The installation of this appliance should be carried out by a competent electrician and be in accordance with the current IEE wiring regulations. Fixing Positions This appliance may be either wall-mounted, vertically mounted (CAB only) or fi xed to a ceiling - see Fig. 3 for various fi xing positions and ‘Mounting’ sections below, for fi xing details. A minimum 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). There should be at least a distance of 500mm from the front of the heater and any obstructing surfaces. When horizontally mounted, this appliance should not be mounted less than 1.8m from the fl oor. This appliance should not be fully encased. The unit must be installed in an area where airfl ow into and out of the heater is unobstructed. 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 fl oor 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 fi bre inserts. The plug must be located in the solid part of the wall and not just in the plaster layer. When fi xing 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 fi xing. Once the wall bracket has been fi tted, 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 suffi cient strength - see Fig. 3b. Vertical Mounting When mounting the CAB units vertically use the mounting kit CABVM1. Multiple Units When connecting multiple units together use the kit CABM1. Electrical connection All products are fi tted 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. Means for disconnection must be incorporated in the fi xed wiring in accordance with the wiring rules. 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) fi tted 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) fi tted 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 or closed switch, as required for the application should be wired as per Fig. 7 & 8. 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 fi rmly clamped before operating the appliance.9 Switch Panel Installation The backing box (standard double gang) should be mounted onto a suitable 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;

Standby 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 fi tted. 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 to Standby using the switch box control, and not switched off by mains power supply interruption. When the unit is switched to Standby (via the switch box) the fan will run on for 1 minute without heat to discharge any residual energy from the heating elements. When fi rst turned on the control will run through a system check. The selected settings will be reached and maintained after a 30 second period. 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 fl ow 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 fi tted as close to the air barrier connection points as possible. For commissioning, air bleed valves (see ‘c’ in Fig. 5) are fi tted 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. Thermostatic control (optional) By including a single pole bi-metallic or electronic thermostat to the connections as per 'C' in Fig. 7 the following functionality is introduced dependant on heat switch setting. - Fan only - No eff ect - Half Heat - Heater will reduce to Fan only - Full Heat - Heater will reduce to Half Heat 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

3. Blower unit stalls.

To reset the thermal safety cut-outs, access reset buttons by following the steps below; a. IMPORTANT - Isolate electric supply. b. Remove the inlet grilles using a fl at head screwdriver, loosen both outlet grill screws to remove the grill (‘x’ in Fig. 4) c. Using a Philips head screwdriver, remove the three M4 screws to remove the bottom panel (‘z’ in Fig. 4) d. Locate and remove the two M4 screws located behind the inlet grills on the lower left and right hand sides (fi xed to the end caps) e. Rotate and remove the inlet grill to expose the safety cut-outs (‘t’ Fig. 10) Before re-setting the reason for activation must be determined and corrective action taken. Door switch control (Electric models) By including a door switch in the circuit as per ‘D’ in Fig. 7, the air barrier will respond to door openings as follows: (1) Door opening will energise the air barrier at the set conditions (switch box settings). (2) On door closure operation will continue at the set conditions for a further 1 minute. (3) Between 1 minute and 2 minutes from door closure, set back operation, ½ heat (if heat selected) and ½ fan will activate. (4) Between 2 minutes and 3 minutes, the fan only (½ speed) shut down cycle will be engaged. (5) After 3 minutes, the air curtain will return to a dormant state until the door is re opened. If the door re-opens during this 3 minute run on cycle, the process will restart at (1).10 Low pressure hot water heated / Ambient (fan only) variants Operation using switch box - CABC6 Switch on electrical supply to the air curtain. Rotate the switch to the desired heat setting. Settings available are; OFF - Low Fan - High Fan The rocker (auto / manual) switch allows for manual over- ride of a door switch if fi tted. 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 control, and not by mains power supply interruption. When fi rst turned on the control will run through a system check. The selected settings will be reached and maintained after a 30 second period. Thermostatic control (optional)

1) A thermostatic regulation valve with a remote sensing

bulb (not supplied) can be positioned in the supply water pipe-work to regulate the heat output.

2) An electrical 3-Port Solenoid Valve can also be

connected into the system. Please contact your service agent using the contact details for more details. Door switch control (Water / Ambient models) By including a door switch in the circuit as shown in Fig. 8 as appropriate, the air barrier will respond to door openings as follows: (1) Door opening will energise the air barrier at the set conditions (switch box settings). (2) On door closure operation will continue at the set conditions for a further 1 minute. (3) Between 1 minute and 2 minutes from door closure ½ fan set back operation will activate. (4) After 2 minutes, the air barrier will return to a dormant state until the door is re-opened. If the door re-opens during this 2 minute run on cycle, the process will re start at (1).
