General Information 1.1 Introduction This instruction manual describes the Airbloc ACR Recessed range of air curtains. 0 F1 Models range from 1000mm to 2000mm in length, in both Standard and High capacity and are available in either Electrically heated, Ambient or LPHW. They are designed for discreet positioning in a suspended ceiling or bulkhead in the doorways of retail or commercial premises. Optional case for doorways with restricted space and no suspended ceiling/bulkhead are available.
BMS control, time switches, room thermostats and door interlocks can be installed at the discretion and responsibility of the installer. below. The clearance allows for cable entry and prevents combustible surfaces overheating. All units must be wired in accordance with I.E.E regulations for the Electrical Equipment of Buildings and the installer should ensure that a suitable isolating switch is connected in the mains supply. The minimum mounting height (floor to grille) is 1.8m.

5. Installation Details. 5.1 Mounting Airbloc units should be installed horizontally directly over the door opening. They are designed for discreet positioning in a suspended ceiling or bulkhead in the doorways of retail or commercial premises. The unit can also be mounted within an optional case for doorways with restricted space or no suspended ceiling or bulkhead.
Step 3 Step 6 Access to the inside of the air curtain grille can be made. Open the grille. The grille is hinged to prevent the inner frame from dropping. Either drop rods or catenary wire (available from manufacturer) can be used to fasten the air curtain to the ceiling support structure. Note When using drop rods the casing mounting brackets are slotted and the mounting plates provided must be used on assembly.
After fitting the product in the ceiling recess and adjusting the height to ensure that the grille sits flush to the ceiling (when re-fitted) take the grille assembly and refit using the screws removed during Step 5. 5.5 Installation details Option SmartElec2 Controller 5.4 Installation details AC-ACR-PANEL programmer The SmartElec2 program panel is installed in a separate housing and connected to a surface mounted back box in a suitable location. Please see fig 7.
5.6 Installation details - LPHW Only Fig.9 LPHW connections. Flow connections To avoid risk of transit damage to the flow and return connections, ON LPHW STANDARD CAPACITY ONLY the heating coil is provided loose inside the case together with the air deflector plate and side supports. NOTE: HIGH CAPACITY LPHW COILS ARE PRE-FITTED. To install, unpack the loose items and identify the two side supports as shown below and fit to the inner side of the case using the screws provided.
5.7 Installation wiring Install the ACR unit using drop rods as previously described. With the grille door open, connect the electrical supply and program panel interconnecting wiring/ factory supplied cables to the relevant terminals on the controller base unit. Connect any interconnecting wiring/factory supplied cables to the programme panel. Connect any optional wiring as required. For full details see wiring diagrams in section 4.
6. Servicing & Maintenance. ALWAYS ENSURE THAT THE MAIN EXTERNAL ELECTRICITY SUPPLY IS SWITCHED OFF BEFORE COMMENCING ANY MAINTENANCE ON THIS HEATER. Step 2 Access to the inside of the air curtain grille can be made. To obtain the best results from the heater, it is essential to avoid the accumulation of dust and dirt within the unit on the air inlet and discharge grilles. For this reason regular cleaning is necessary, paying particular attention to the removal of dirt build up on the rotor blades.

8. Fault Finding. 8.1 General 8.4 SmartElec2 Controllers. If the air curtain does not operate after running through the detail provided in Section 6, then a suitably competent service engineer should be called to identify the nature of the fault. The SmartElec2 control raises an alarm if any of its inputs are outside their normal working scope. Alarms are displayed on the program panel as a code with a prefix "E". 0 E6 The first number represents the air curtain address. See chart over.
The system can be reset by powering-up the panel whilst holding down the and . buttons. Alternatively, the engineer’s mode automatically self-clears after approximately 10 minutes of non -activity on the switches. The display shows the ‘start’ pattern but then goes blank. Release the buttons where upon the display resumes and the system addressing commences, finding only those air curtains which are actually connected and working.
9. Parts replacement. 9.1.1 Electrical element replacement SE. 9.1.2 Electrical element replacement HE. Step 1 Using a 4mm Allen key slacken the M6 Allen screws at the side of the grille. Access to the inside of the air curtain grille can be made. Open the grille. The grille is hinged to prevent the inner frame from dropping. Step 1 Using a 4mm Allen key slacken screws securing the grille. Remove 4 screws securing the top of the case and remove. Slacken two hinging bolts on both ends.
9.2.1 Rotor and motor replacement SE Step 1 Using a 4mm Allen key slacken the M6 Allen screws at the side of the grille. Access to the inside of the air curtain grille can be made. Open the grille. The grille is hinged to prevent the inner frame from dropping. Note: when refitting ensure that the grub screw bears on the flat of the motor shaft. Step 5 Push the rotor support bracket away from the rotor to release the rotor bearing.
Step 9 Swing the movable bracket clear and remove the motor. Step 4 Turn retaining latch to release chassis. Movable bracket 9.2.2 Rotor and motor replacement HE Step 5 Holding handle, carefully pull motor and air wheel assembly forward. Step 1 Using a pozidrive screwdriver undo screws securing the grille and remove. Remove 4 screws securing the top of the case and remove. Slacken two hinging bolts on both ends. Remove three bolts securing the access plate. Carefully hinge down the access plate.
9.3 LPHW coil replacement. Step 1 Using a 4mm Allen key slacken screws securing the grille. Remove 4 screws securing the top of the case and remove. Slacken two hinging bolts on both ends. Remove three bolts securing the access plate. Carefully hinge down the access plate. Note: Take the weight as access plate swings down. Step 2 Disconnect flow connections with appropriate tools. Step 8 Disconnect the wires from the motor to the controller base unit.
