Page 5: Handling
If the unit is handled by a lifting beam + slings, tubes need to be placed in the holes provided in the support feet. Ensure that the crane hook adapter is large enough to prevent the belts applying any pressure to the AHU casing. Furthermore, ensure that the steel tubes are secured to prevent any movement. If the above-mentioned lifting methods cannot be used, the unit may be lifted using a forklift truck, taking great care not to dent the lower panel (use forks of a sufficient length). Follow the applicable handling rules. 39HXC, 39HXE and 39HXEZ models Procedure for uncoupling 39HX multi-blocks or assembling the 2 blocks for the 39HXEZ 100 & 150 1 Remove the 4 nuts and screws Undo the screws on each beam and remove them. - Page 6 3 - HANDLING Disconnect the electrical connectors on the control and disconnect switch. 4 You can now separate the blocks. Note: Follow the procedure in reverse to re-couple the blocks, particularly for the 39HXEZ100 & 150. When uncoupling the blocks, ensure that the 18X10 PVC gasket located between the blocks remains correctly in place to guarantee a perfect seal. If necessary, fit one. NB: if there is a roof, remove it first in accordance with the instructions given on the roof fitting plan (see technical specifications). 39HXC, 39HXE, 39HXEZ and 39HXV models These models are placed directly on a flat, smooth floor. The flatness value must be the best possible, around one per thousand. Under normal conditions of use, there is no need to fix the unit to the floor. The unit's support feet must be standing fully on their contact surface. It is important to allow sufficient service space to facilitate maintenance operations.

Switch off the electrical supply to the air handling unit before carrying out any work Details of hinges/handles: Allen key locks, size 4 When they are unlocked, the handles are in "hinge" mode. It is possible to unlock a single row of handles to open like a conventional door. If all of the handles are unlocked, the door can be removed. Handle locked Handle unlocked Door 7.1 - FILTERS After commissioning, the speed of filter fouling will depend on the care taken when cleaning the air flow circuits. Hence the frequency of filter checks should be increased during this period. Maintenance intervals The filter life depends essentially on the amount of dust in the air and the efficiency of the filtration system. The filtration quality cannot be maintained if the filter medium has been damaged during maintenance. We recommend that the filters be replaced once every two years, even in the case of moderate use Filter replacement method During filter maintenance operations, it is important not to spread the dust that has accumulated in the filters. Shut down the unit, Access the filters by opening the door panels, Simply pull on the filters Pull out the slide-type terminal (present on the 39HXC, 39HXE & 39HXEZ models ≥ 3000 m3/h); the filters can then be removed. For the other models, simply pull directly on the filters. Example: 39HXC Slide-type terminal Filter... -
