Instruction for unloading on the site as well as installation and connection F.1 | 11 Air handling unit in operation The pressure difference between interior and exterior of the unit must not exceed 8 in w.g.. Before start-up of the unit, all ducts and protective devices must be mounted to prevent any access to rotating fan impellers. All inspection doors must be closed and locked when the unit is in operation. Do not use the unit without filters.
12 G.1.4 | Instruction for unloading on the site as well as installation and connection Pre-assembly storage The AHU must be protected from the weather and accidental impact. Plastic packaging must be removed and the unit covered with tarpaulin or similar materials. In order to minimize condensation, sufficient air circulation must be ensured between the covering and the unit. G.2 G.2.
Instruction for unloading on the site as well as installation and connection G2.3 | 13 Outdoor units — support under the base frame of the unit The installer must provide a platform that supports the base frame of the unit under the inspection side and under the back side of the unit.

14 G.2.4 | Instruction for unloading on the site as well as installation and connection Installation on the site of unit sections Caution It is strictly forbidden to lift a section under the top of the section. The plastic corners and brackets are not at all reinforced for lifting the unit under the top. There is serious risk of injury and damage to property from heavy components falling. Pull sections together with a strap.
Instruction for unloading on the site as well as installation and connection | 15 Note: Never place the strap on the vertical profile too close to a corner, because the plastic corners and the profiles are not reinforced for the heavy load and stress created by the tensioner when a section is pulled along the base frame or on the floor. Place the strap on the bottom profiles of the unit to avoid any load and stress on the vertical profiles when sections are pulled together along the base frame.

Panel filters are available in MERV 8 and 13 ratings. Other MERV ratings can also be ordered. 2 inch deep panel filters are available as a standard option. 4 inch deep panel can also be ordered. Note: Special sizes of filters and MERV ratings are available from Camfil. M.4.
Adjustment and maintenance operations Place the self-adhesive strip on one vertical side of the filter fame Check that the end of the strip is fully even with the horizontal side of the filter frame. Remove excess of the strip. The end of the strip must be fully even with the horizontal side of the filter frame. Push the filters carefully in the U-profile to be sure that there are no leakages between the filters.
40 | Adjustment and maintenance operations The end of the last filter is fully even with the end of the U-profile. The rubber profile on the inspection door will close the gap between inspection door and filter. Job is done. Check that rubber profiles on the back panel as well as rubber profiles on the inspection door are without wear and damage — still sufficient for avoiding any air leakage. M.4.2 Panel filters The filter cell guide rails are to be cleaned before fitting the new filters.
Adjustment and maintenance operations M.5 | 41 Other Components to maintain M.5.1 The unit It is very easy to remove inspection doors for access to cleaning, service, repairs and replacement of components in the unit. Lift the stainless steel shaft in the hinge to remove the door The unit should be cleaned once a year when operating with normal air quality for comfort ventilation with no special hygiene requirements.
42 | Adjustment and maintenance operations The damper blades are fitted with synthetic bearings requiring no lubrication. Air-tightness of the damper, when the damper motor is in the closed position, must be visually checked once a year. The damper motor is to be adjusted if the damper does not close tightly. M.5.3 Energy recovery wheel The energy wheel is to be checked at least once a year to ensure that it can turn freely and easily.
Instructions to enable adjustment and maintenance safely M.5.10 | 43 Plug fans Dust can accumulate on the fan impeller which can cause imbalance and vibrations. The fan impeller must therefore be checked once a year and cleaned, if necessary. Anti-vibration mounts and flexible connections should be checked at the same time. If the anti-vibration mounts are damaged in any way they must be replaced. M.5.
44 | Instructions to enable adjustment and maintenance safely N.1.2 Personal protective equipment for maintenance staff – health and safety Use the below-mentioned personal protective equipment for maintenance: • Cut-resistant gloves for protection against injury from sharp metal plate edges. • Hard Hat • Particulate respirator – maintenance free including foam face-seal and adjustable pre-threaded headbands – for replacing filters.

4-1 | ERW maintenance Annex 4 ERW maintenance Applies to Innergy tech Wheels installed in Geniox Units 4.1 ERW Bearing Wheel bearings are greased before shipping, but it is recommended to grease them again before start-up. Proper care and maintenance of the wheel bearings should allow it to last for up to twenty years. The recommended lubrication interval is every 6 months.
ERW maintenance | 4-2 Belt tensioner replacement The belt tensioner replacement is achieved by following these simple steps: 1) Lift the locking pin while pushing down on the motor to release the belt tension (a). 2) Incline the motor to remove the belt around the tensioner (b). 3) Unscrew the belt tensioner (c). 4) Install a new tensioner with a small angle inclined away from the motor (about 5-degree angle).
4-3 | ERW maintenance Belt Installation To install a spare belt or reduce the length of the current belt, follow these 5 easy steps: 1. Open/separate the belt by twisting the link tabs sideways and pulling the surplus out of the belt (see image below). If needed, adjust the length of the belt by replacing or removing the undesired links. a. Twist tab at a 90° angle b. Pull link out c. Twist belt end d. Pull out belt end 2. Tape one end of the belt on the perimeter of the wheel.
ERW maintenance | 4-4 3. Pull the belt tightly around the wheel and the gear reducer’s pulley. Connect both ends of the belt (see above image d. to a.). 4. Pass the belt over the tensioner idler sheave and place the motor to its initial position (a). 5. Visually inspect that the belt is not twisted around the rotors and is properly located through the side seals. If the belt tension is too low (see figure), reduce the length of the belt. 4.

It is factory installed and adjusted. No seal adjustment is required in the field. LOW FRICTION SIDE & CENTER The low friction side and center seal are contact seals fixed to the wheel frame.
ERW maintenance | 4-6 Media Cleaning Due to their inner laminar flow and self-cleaning feature, the I4 wheels are resistant to dust build-ups. As no particle will accumulate inside the media, only the edges need to be cleaned. If the wheel application is such that cleaning is needed, a vacuum cleaner with soft brush tip and compressed air with a flat nozzle blowgun (70 psi) is recommended to clean both sides of the media.
