NB: terms such as "pending unwrapping" and "unit damaged but packaging in good condition" are not admissible by insurance companies. For all other problems, please contact your CIAT representative for further information. The unit must be stored in its packing and sheltered from weather. -
Page 4: Setup
It is also important to leave sufficient space around the units to allow access to the various components: bearings, belts, motors, filters, coils, etc. Refer to the diagram below to ensure trouble-free maintenance. a clearance of 600 mm is recommended for assembling the sections 2.3 Setup Handle the boxes carefully. -
Page 5: Assembly - Fitting
3.2 Assembly - Fitting The damper sleeve and ducts are connected to the AHU using 5.53 sheet metal screws. The box(es) making up the air handling unit must be installed on a flat, sturdy surface. To ensure a tight seal between joined sections, they must be shimmed and levelled to compensate for any unevenness of the mounting surface. - Page 6 15 x 8 mm Fastening clamps are supplied for a tighter fit between sections gasket on size 150 and higher air handling units. They may be placed on the sides or tops of each section. - Trace the mounting holes (centre distance: 38 mm) and drill a diameter 4 hole.
- Page 7 (50 x 20 foam gasket). Fit the roof panels along the entire length of the unit, placing a foam seal (supplied by CIAT) between each panel. Assemble the panels as per the roof diagram and drawing supplied with the unit...
- Page 8 In addition the rules mentioned on the previous pages, special care must be taken with the hydraulic system (do not forget the risk of freezing temperatures). If the unit is fitted with an external air intake, we recommend protecting it from prevailing winds and any exhausted air or gases (chimneys, roof extractors, etc.).

Page 9: Filtration
3.3 Filtration - G2 filters: the cell may be inserted in any direction regardless of the direction of air flow, - G4 filters: the mesh holding the medium in place must face the discharge air side, - HPS bag filters HPS (F6, F7, F8), high-efficiency and HPR filters: the cells on the frame side must face the incoming air, - HEPA filters (H10, H14): refer to the instructions supplied with filters for information on fitting and maintaining them, - Carbon filters: refer to the instructions supplied with the filters. - Page 10 Coil maintenance - Clean air is essential to the efficiency of the unit. Use an air filter. - The coil may be cleaned with compressed air. However, make sure particles are not blown into any other sections of the unit. - If a glycol/water mix is used in water-cooled heat exchangers, check the glycol/water ratio.

Page 11: Electric Heaters
Direct expansion coil Installation must be performed by qualified personnel. For coils containing "SPLIT SYSTEM" refrigerant, the unit must not be stored near to a source of heat or in direct sunlight (increase in refrigerant pressure). Droplet eliminator They are placed downstream of the cooling coil. Clean them once a year with suitable products to remove any deposits. Specially designed products are available for this operation. -
Page 12: Control System
A suitable air flow rate controller (pressure switch, switch indicator, etc.) must be placed in the circuit to shut off power to the heaters should an air flow fault occur. CIAT shall not be liable if this requirement is not followed. Never operate the coil with the fan off. - Page 13 ‡ Aligning the pulleys by placing a ruler flat against the pulley flange and adhering to the data below. for variable-diameter pulleys, align them along the centre line. - Hold the pulleys in place with the appropriate tool, Alignment axis D max <...

Page 14: System Start-Up
4. SYSTEM START-UP Keep all inspection doors closed while the unit is operating. A safety device protecting against insufficient air flow must inserted in the fan control. Connect all electric components to earth. 4.1 Connecting the electric motor The connection must be made by a qualified technician, as per the diagrams below and those included with the motor. Before powering up the motor, test the insulation resistance. -

5.3 Air filters Filter fouling can be determined by testing the pressure drop. CIAT's range of AIR air handling units are fitted with pressure tappings. The various types of filters are shown in section 3. G2 filter The cells must be periodically vacuumed. To remove greasy dust, the media may be cleaned with warm water (50°C max.) and detergent. -
Page 17: Humidifiers
5.4 Humidifiers The type of humidifier used and the water quality must comply with the regulations in force. The upper limit value for non-pathogenic bacteria is 10,000 CFU/ml (Colony Forming Units). However, it is best to check and clean the air handling unit from 1,000 CFU/ml onwards (standard EN 13053). -
Page 18: Fan Motor Assembly
5.5 Fan motor assembly Theoretically, the scroll housing, impeller and shaft require little servicing unless the air drawn in is dirty and unbalances the impeller. If the air is very dirty, check the filters and their assemblies. Once a year check the anti-vibration mounts, the sleeve seals, etc. Bearings The rate at which the bearings require servicing depends on the fan usage conditions. - Page 19 GGS warm air generator See the instructions provided with the unit. MK D and MK V air stream gas generator The electrical panel is delivered as standard on the front panel. Generator delivered in a crate, not fitted to the unit. To be assembled on site by the fitter. Outdoor MK D and MK V air stream gas generator machine room See the instructions provided with the unit.
