The CSD mounting frame (CSD-MF) is a base frame which is designed to be built into a solid ceiling. Once the frame has been installed the CSD is then inserted into this mounting frame to complete the installation.
The CSD-MF offers a vastly improved alternative to the standard method of CSD installation. This system will not only save time for all of the contractors involved (HVAC, ceiling erectors, plasterers etc.) but will also give a much higher standard of finish than was typically able to be achieved.
Normally ceiling slot diffusers are one of the most difficult supply diffusers to install into a solid ceiling. During the process of installa tion it is not uncommon for both the plasterer and the painter to have to carry out remedial work to ensure a reasonable standard of finish is achieved. All of this work is obviously detrimental as it takes time and often damages the linear diffuser and contributes to the poor overall appearance of the CSD.
The CSD-MF is installed as part of the solid ceiling grid system. This allows the supply air boots to be installed when there is clear access to the ceiling space and there is no danger of damaging the high quality finish of the CSD. When it is time to line the ceiling the ceiling erector has a slot to
slide the gib or plaster sheet into. Once the plasterer has “stopped” the ceiling sheets the painter is free to paint the entire ceiling without having to be concerned with masking the CSD which is not yet in place. When everything has been finished to the required standard the CSD itself is just simply pushed up into place to completely conceal the mounting frame.
The CSD-MF has many features designed into it to enable a faultless CSD installation. The mounting frame is equipped with a flexible edge which is fastened to the adjacent steel or wooden ceiling battens, whichever is used. This flexible edge allows for any discrepancies in the ceiling itself.
If the flexible edge does not take up any discrepancies in the ceiling the solid main section of the frame remains rigid to provide an accurate slot for CSD. The frame is also designed to accept the gib or plaster sheet accurately, however if there were discrepancies the plasterer can plaster out those discrepancies.
With all these features the use of the CSD-MF will not only save time in installing the CSD but will also result in a much higher standard of finish for the installation.

Performance NotesGeneral Notes on performance charts for single or multi slot linear diffusers in this section.1. All pressures are Pa (N/m2).2. Projection (throw) values in metres are based upon the performance of a
one metre long active section. When only 300mm is active, the values are 0.6 times those shown. For a 3 metre long continuous length, the values are 1.8 times those shown. See table below:
H : Horizontal projection : Minimum is to a terminal velocity of 0.75m/s and maximum to 0.25m/s.
V : Vertical projection is to a terminal velocity of 0.25m/s.3. Spread is the maximum width of the jet defined by the above velocities.
4. N.C. values are based upon horizontal projection from a three metre active section and a room absorption of 10dB re 10-12 watts.
Vertical projection values are 11dB less than listed.5. N.C. correction for length:
6. Figures for plenum fed diffusers are for essentially zero inlet velocity. The velocity profile is relatively uniform for the length of the active section.
7. Figures for adapter fed diffusers take account of the effect of the adapter and inlet neck on diffuser velocities which tend to be less uniform and produce a velocity profile of the shape shown in the Velocity-Throw diagram above. The 0.25m/s isovel generally shows a projection reduction at the centre of approximately 25%.

NotesGeneral Notes to be read in conjunction with performance tables on the following pages.This data is reliable information for cooling, ventilating and heating applications.1. All pressures are Pa (N/m2).2. Minimum throw values refer to a terminal velocity of 0.75 m/s and
maximum to 0.25 m/s, for a 1200mm active section with a cooling temperature differential of 12°C.
The multiplier factors listed in the table below are applicable for other lengths.
3. The NC values are based on a room absorption of 10dB, re 10-12 watts and a 3000mm active section.
Use the following multipliers for other active lengths.
4. Return Intake - When used as a return intake the NC value given will be increased by 4 and the negative static pressure will be 0.8 times the total pressure shown.
Fineline DiffusersSERIES LD linear bar grilles are designed for supply and return air distribution in heating, cooling and ventilating applications which call for diffusers having long or con tinuous slender appearance, fixed air discharge angles of zero or 15 degrees, and installed in walls, floors, sills or ceilings.
CONSTRUCTION is of extruded aluminium face, bars and frame of alloy 6063-T5, notched mullions, mechanically compressed together to form a powerfully bonded core, which is welded at mullion ends to the frame. ‘F’ models for floor use, have double mullions and 30 x 30 x 15 x 3 Solid ‘Z’ frames.
WIDTH maximum for ‘F’ models is:
Continuous traffic: 200mm, Occasional traffic: 300mm. All models can be furnished with mitred 90° corners, or other angles where metal templates are furnished to the factory. Refer illustrations on this sheet for corner descriptions. The minimum length is 200mm. The maximum length for a single section is 2.8m.
Accessory DamperAvailable with opposed blade dampers, lever/screwdriver operated through the face. Specify OBD#1.

Series LD – Floor Grilles
Model LDH-CF Computer Floor GrilleHeavy extruded aluminium construction with double mullion support bars notched at each blade intersection. The assembly is compressed mechanically to form a powerful bond between blades and mullions.
Vertical throw units have been independently tested to 500kg concentrated load on an area of 645mm2 (1 square inch) at the centre. Deflection under load is 0.66mm and there is no permanent deflection.
Units are also available with 15° air divergence left, centre 0° and 15° right, in equal sections, to provide a wider spread of discharge air, and a reduction of approximately 20% of rated throw.
Grilles are manufactured in standard 600 x 600 modules, 32 mm thick and are designed to replace any standard floor tile. They are compatible with most computer floor systems.
For Special Size, Thickness and Discharge applications, refer to your local Holyoake Branch.
AccessoriesVolume control damper OBD #2 (adjustable through louver face).
Modular Floor GrillesModular Floor Grilles are available with parallel or cruciform mullions, using 115 x 115mm square LD or LDH – removeable core elements.
Sizing ParametersD = Nominal Duct Size
A = Actual Neck Size
N = Number of Core Elements
D = N x 120 + 20
A = N x 120 + 3
e.g. 2 x 120 = 240 + 20 = 260 Nominal Duct
2 x 120 = 240 + 3 = 243 Actual Neck
Cores may be O degrees or offset 15 degrees to achieve a range of discharge patterns.
Construction is of Style 2 or 7 outer Frame with core and mullion as applicable.

The Holyoake Flangeless Grille Series - PMF, has been developed to keep pace with contemporary interior designs.
The Series PMF is versatile and can be used with all LD Series Linear Bar Grilles.
Designed for sidewall applications* the Grille Series – PMF offers a new approach to interior air supply/return.
For supply and return applications, the Holyoake Series PMF Flangeless Frame Grilles are the least intrusive sidewall supply or return air product on the market.
ConstructionConstructed from extruded aluminium to precise Holyoake quality standards, the Holyoake PMF Plaster Mounting Frame makes flangeless grille installation easy and provides a superior finish.
InstallationThe PMF plaster mounting frame negates the need for any costly additional aperture framing or nogging and is fitted into the wall or bulkhead cavity prior to the wall lining being applied.
The PMF mounting frame can be fitted using rivets, nails, or adhesive, although drive or Tek screws are the most efficient method.
A series of grooves in the mounting frame are provided to prevent screw run-off.
Once the wall lining is in place, the applicator can stop and finish the wall opening up to the PMF frame edge and prepare the surface for paint finishes.
The Series - PMF Flangeless Grille need only be fitted to the complete and finished wall by pushing the grille into the mounting frame firmly, the retaining clip will grip the serrations in the frame and pull the grille up neatly to the wall surface.
* Also suitable for ceiling or floor mounting, with appropriate construction.
• Attractive Appearance
• Designed for Side Wall Applications*
• Versatile
• Multiple LD Core Types
