Provision should be made to suspend the supply or return air plenum boxes (if specified) behind the plaster board / timber frame in such a way that no weight from the plenum is transferred to the grille border. The minimum opening size for the plasterboard aperture should be based on the specified grille type and nominal size (refer to project schedule for unit sizes). Minimum opening sizes relating to the nominal grille size are detailed on pages 3, 4 & 6 of this technical leaflet. Behind the plasterboard, a sturdy timber batten frame is to be provided (by others) to match the opening size within the plasterboard. The minimum combined construction depth for plasterbord & batten should be between 40mm up to a maximum of 60mm. Each AK plenum box is to be installed using suitable threaded rod or wire supports (by others) to take the weight of the plenum. IMPORTANT; To ensure a good seal against the diffuser face, the edge of the plenum should sit square within the opening and flush with the unfinished plasterboard face. Construction Vertical section Plenum supports (By others) Timber Batten (by others) AHP / WAPP / ADMP ('H' - 4 / 'L' - 4) ALSP ('A' + 18 / 'L' + 38) MIN Plasterboard Opening Plasterboard (by others) MIN Depth 40mm MAX Depth 60mm 8 Plenum neck flush with plasterboard face (pre-plaster skim) Installation Instructions Installing the blanking plate Where optional blanking plates have been supplied, these must be fitted to the rear of the grille before the grille is installed into the builders work opening as it is not possible to install these once the grille is in situ. To determine the location for the blanking plates, offer up the grille to the builders work opening and mark on the plaster flange using removable tape, the area where supply or return plenums are not installed and where return air through the grille is not required. IMPORTANT; Ensure that the blanking plate installation does not cover any active area of the grille as this will restrict the flow of air through the grille. Remove the grille from the opening and place face down on a suitable protected work surface, ensuring the area is free from debris to avoid damaging the painted surface. Blanking plates and foam insulation are supplied loose, in lengths for site cutting and installation to the rear of the grille neck. Cut the blanking plate and foam insulation to the required length(s) to cover the areas marked as non-active, ensuring edges are clean and burr free. To install the blanking plate/tray to the grille neck; AHP / ADMP: Lay the foam insulation into the grille neck with backing facing away from the grille face. Insert the straight edge of the blanking plate into the channel on the rear of the grille neck and gently lever the tabs into the channel on the opposite side to engage the blanking plate. ALSP: With the foam insulation cut to the correct size to match the blanking tray, carefully peal off the self-adhesive backing and stick the foam insulation to the inside of the blanking tray. Place the blanking tray over the neck of the diffuser and secure into position using No. 8 self drilling screws (supplied by others) through the pre-formed Ø3.5 holes provided within the blanking tray along both sides. AHP, ADMP & ALSP: Once the blanking plate/tray is installed in the correct position, apply a continuous bead of mastic to the joint between the blanking plate and the channel on both sides to prevent vibration. Repeat these steps for each section of blanking plate until all nonactive sections of the grille are blanked. 9 Installation Instructions Installing the grille (Finite) The plaster in grille, complete with core, should be installed into the builders work opening, retaining the plastic film on the front of the grille core to prevent marks during the installation. IMPORTANT; The grille core can only be installed within the border in one orientation. Ensure correct orientation of the air blades before final screw fixing into plasterboard opening. Ensure the grille border is flat and level before fixing it in place then secure using counter sunk head 3.5 drywall screws every 300mm. Screw through the holes in the border, through the plaster board and into the timber batten behind. Ensure the screw heads are driven firmly into the border and sit below the top edge of the grille border so they will not visible when the border is plastered. The border should be firm with no movement. Jointing tape should be applied over the plaster frame to provide a good adhesion surface for the plaster skim. IMPORTANT; Care should be taken not to stretch the grille border apart during the installation as this may affect core retainment. With the grille secured in the plaster board panel, remove the grille core (refer to page 11 for details on AHP & ADMP core removal) and store in a safe place, clearly marked with the location reference to avoid accidental damage or disposal. IMPORTANT; Mitred corners (if supplied), along with ALSP plaster in slot diffusers are fitted with non-removable cores therefore suitable site masking of the grille core is required to prevent damage. The plaster can then be applied using the top edge of the grille border to level the plaster. Excess plaster should be cleaned off the inside of the grille & border before it dries to avoid staining or damage to the paint finish. Installing the grille (Linear) Linear grilles will be supplied with alignment pins and a blade alignment fixture (AHP & ADMP). The alignment fixture is supplied flat and should be formed by hand before installation. Before installing the grille border into the builders work opening, arrange the grille sections next to each other on a clean, level surface with the alignment pins and blade allignment fixture to hand to ensure a good fit prior to installation. Blade alignment fixture Insert the alignment pins halfway into the alignment ports located in the border extrusion on one grille section. Insert the formed blade allignment fixture into the extrusion channel at the rear of grille border. IMPORTANT; Install the allignment fixture with the grille installed within the border to ensure correct orientation. The grille border sections can then be offered up to the plaster board aperture and installed in the same manner as the finite grilles detailed above, ensuring both allignment pins and blade allignment fixture are correctly installed between each section. Once the grille border has been secured in place, remove the core (refer to page 11 for details on AHP & ADMP core removal) and centre the blade alignment fixture between the two sections. Mastic should be applied to the top and bottom of the blade allignment fixture where it meets the border extrusion to prevent movement or vibration. Store the grille core sections in a safe place, clearly marked with the specific location reference to avoid accidental damage or disposal and to ensure correct core is re-installed within the relevant border section. IMPORTANT; Each core section is specific to an individual border section. 10 Alignment pin Installation Instructions Removing the grille core (AHP) Type AHP plaster in grille is supplied with a removable cores for access to supply or return air plenums or volume control dampers (if specified). The AHP core is retained within the border using friction bungs installed at the top and bottom of the grille core support tubes. To remove the grille core, use a suitable hook tool (supplied by others) to gently pull the top blade away from the border at both ends of the grille. IMPORTANT; Removal of the grille core from the border is a 2 person operation. Do not attempt to remove the grille core as a single person operation as this can cause damage to the grille or plasterwork finish. Care should be taken when removing the grille core for the first time as the safety wire restraints will not be fitted. When removing the grille core, excessive force can result in damage to the plaster finish surrounding the grille border. Installing the grille core (AHP) Once the plaster/ paint finish is properly dry, unwrap the grille core and safety wires ready for assembly. 2 No. safety wires are included in a bag supplied with each grille core section. Before installing the grille core, safety wires must be clipped to the pre-formed holes provided at each end of each grille core. The holes are located on the top blade, approximately 50mm in from each end blade support tube. For grilles with 15° angle blades, holes are provided in top and bottom blades to allow core roation and airflow direction control. Care should be taken when installing the core to ensure correct blade orientation. Disengage the clasp at the end of the safety wire, prise open the clasp and thread through the pre-formed hole within the grille core. Ensure the clasp is correctly reengaged once installed (refer to photo). Repeat this process at each end of the grille core. Open the clasp at the free end of each safety wire and prise open, ready for the final assembly to the grille border. Safety wires IMPORTANT; Installation of the grille core into the border is a 2 person operation. Do not attempt to fit the grille core as a single person operation as this can cause damage to the grille or plasterwork finish. IMPORTANT; The grille core must be supported with the blade containing the preformed hole at the top (refer to photo) and the finished grille face towards the operative (pre-fored hole will be at the back of the blade). With one operative supporting the grille core directly below the border, another operative can carefully loop the safety wire around the corresponding mullion within the border and thread the open clasp back through the pre-formed hole within the grille border. Ensure the clasp is correctly re-engaged once through. Once both wires are attached at both ends, the grille core can be offered in to the grille border. The grille core should be lifted upwards until the core is level with the opening before gently pushing the core into the border Mullion The grille core should be carefully pushed into the border ensuring even pressure along the entire length of the grille. Each grille section should be visually inspected once installed to ensure the grille core is flush with the border profile. Any areas where the grille core does not sit flush should be inspected. 11 Installation Instructions Removing the grille core (ADMP) Mullion Type ADMP plaster in grille is supplied with removable cores for access to supply or return air plenums or volume control dampers (if specified). The ADMP core is retained within the border using spring clips, captured within support mullions spaced along the length of the grille core. Spring Clip IMPORTANT; Removal of the grille core from the border is a 2 person operation. Do not attempt to remove the grille core as a single person operation as this can cause damage to the grille or plasterwork finish. To remove the grille core, first locate the spring clips by looking into the grille through the air discharge slots. Using a suitable non-abrasive pry tool (non-metallic), hook the grille support tubes and gently pull the core away from the border, supporting the weight of the core. Care should be taken when removing the grille core for the first time as the safety wire restraints will not be fitted. When removing the grille core, excessive force can result in damage to the plaster finish surrounding the grille border. Ensure support is provided along the entire length of the grille core to avoid damage to the grille or plaster finish. Installing the grille core (ADMP) Once the plaster/ paint finish is properly dry, unwrap the grille core and safety wires ready for assembly. 2 No. safety wires are included in a bag supplied with each grille core section. Before installing the grille core, the safety wires must be attached to the pre-formed holes provided at each end of the grille core. The holes are located on the bottom blade, approximatley 50mm in from each end support tube. Disengage the clasp at the end of the safety wire, prise open the clasp and thread through the pre-formed hole within the grille core. Ensure the clasp is correctly re-engaged once installed (refer to photo). Repeat this process at each end of the grille core. Open the clasp at the free end of each safety wire and prise open, ready for the final assembly to the grille border. IMPORTANT; Installation of the grille core into the border is a 2 person operation. Do not attempt to fit the grille core as a single person operation as this can cause damage to the grille or plasterwork finish. Mullion IMPORTANT; The grille core must be supported with the blade containing the pre-formed hole at the top and the finished grille face pointing away from the border opening. IMPORTANT; The grille core can only be installed within the border in one orientation. Ensure correct orientation of the air blades before final installation into the grille border. With one operative supporting the grille core directly below the border, another operative can carefully loop the safety wire around the corresponding mullion within the border and thread the open clasp back through the pre-formed hole within the grille border. Ensure the clasp is correctly re-engaged once through. Once both wires are attached at both ends, the grille core can be offered in to the grille border. The grille core should be rolled upwards into the opening ensuring the core is correctly engaged within the mullion retaining lips. Mullion Retaining Lip Carefully push the core into the border ensuring that the grille tubes allign with the spring clips fixed to border mullions. IMPORTANT; Ensure grille is secured along the full length and that all spring clips are fully engaged around the grille support tubes using a torch if necessary. 12 Spring Clip Order Details Plaster In Liner Grilles (AHP, WAPP, ADMP) F - AHP-15 / Type - Linear Construction F Finite Construction E End Section M Middle Section 1500 x 150 / P3 / RAL 9010:20% TE A1 EE EE P0 EE EE EE EE P2 EE EE EE EZE P3 EE EE EE EE P4 EE EE EE EE P6 EE EU LxH (see page 3 & 4) Grille Type AHP-0 AHP-15 WAPP-0 WAPP-15 ADMP-1 EXAMPLE Make: TROX Type: F-AHP-15 / 1500 x 150 / P3 / RAL9010:20% Mill Finish Aluminium Powder coated to RAL 9010:50% (white) Powder coated to RAL 9006:25% (silver grey) Standard Finish Powder coated to RAL 9010:20% (white) Powder coated to RAL 9005:20% (black) Special Finish State colour RAL..., BS...
