7.7 Mount duct pipes and grilles Please note that this section and the following subsection provide a general description of fitting the ducting and subsequent sealing. Materials and methods for fitting the ducting depend on the customer’s order, the options chosen, and the actual site, hence we can only provide general guidance on this matter.
7.7.1 Sealing Figure 18 below is a sectional drawing depicting a wall with a duct hole and duct fittings. A unit is installed on the inner wall, i.e. the grey box on the right-hand side marked with the number ‘1’. Figure 18: Sealing the gaps around ducts, sectional drawing Unit Wall...
The AMX 4 unit is supplied with a drain hose, the length of the hose varies depending on the customer's order. Drainage can be done in various ways; one is to connect the drain hose to a waste-water pipe, and another is to lead the hose through the outer wall.
7.9 Remove the transportation safeguard The compressor is secured with a transportation lock, this needs to be loosened before the unit is closed up. Locate the compressor, see Figure 21 below. Locate the transportation lock, see Figure 22. Loosen the bolt and pull it downward. It cannot be disassembled, but it must be loosened completely. The compressor will now be supported/hanging by the springs.
7.10 Reassemble the side covers Reassemble the side covers using the bolts from earlier on, see Figure 23 and Figure 24. Figure 23: Reassemble the side cover – left-hand side Figure 24: Reassemble the side cover – right-hand side 30/52...
