Installation - CombiSteel 7480 Serie Mode D'emploi

INSTALLATION

The installation has to be executed by skilled workers who have the necessary technical qualifications established
by the country where the unit is installed.
Proceed with the installation by following the drawings of the mounting diagrams (See diagrams a÷z2) and what
below-described:

Wall-mounting units: With the help of the forklift truck take the unit in correspondence with the installation
hole, then introduce it in the place prepared; when the unit will be in the definitive position, make holes in
correspondence with the fixing supports (fig. 2-1) and finish the positioning by using the screws provided
(fig. 2-2). As concerns the units forms 4 and 5, after having made holes for the fixing (fig. 2-3) you have to
mount bolts, nuts, washers and support plates provided together with the unit (fig. 2-4). Inject polyurethane
or other insulating material in the split between the perimeter of the hole in the cold room wall and the unit
insulated panel.

Straddle units: Make sure that the cold room ceiling has not been mounted, then take the unit in
correspondence with the installation holes and introduce it in the place prepared. When the unit will be in
the definitive position, install the cold room ceiling, then make holes in correspondence with the fixing
supports (fig. 2-1) and use the screws provided (fig. 2-2). Unscrew the spacer blocks that lie on the
evaporating side by means of the nut till its base leans on the cold room wall (fig. 2-5); screw the nut again
forcing till the evaporator is levelled (fig. 2-6). Join the drainpipe, making it pass through the hole made in
the cold room wall and then introducing it in the plastic union that lies on the condensing side back (fig. 2-
7). Inject polyurethane or other insulating material in the splits left around the evaporator supports.

Ceiling units: By using a forklift truck, take the unit near the hole made in the cold room ceiling, then put it
in the place foreseen. Remove the lifting cable and keep it for an eventual future use. Inject polyurethane
or other insulating material in the split between the perimeter of the hole in the cold room ceiling and the
unit insulated panel.

Split and Bi Block units: Put the evaporating unit in the definitive position by means of the forklift truck,
make holes in the ceiling in correspondence with those already present on the bearing beams of the unit
(fig. 2-8). Fix the evaporator to the wall following the right procedure: threaded bars passed through, like
those provided (fig. 2-9), or expansive inserts or something else according to the structure of the cold room
ceiling. Inject insulating material round the holes in the ceiling. On the wall, where the condensing unit of
the units form 1, 2, 3 is going to be installed, fix expansive inserts with hook supplied with the unit (as
concerns the dimensions, see the mounting diagram). Take the condensing unit to its definitive place and
hang it on the hooks just fixed in such a way that they stick perfectly in the buttonholes that lie on the back
of the condensing unit (fig. 2-10). The condensing units forms 4 and 5 have to be fixed as normally done for
the Wall-mounting units of the same form (figures 2-3 and 2-4). The horizontal condensing unit does not
need any fixing.

Condensing units: See what is described as concerns the installation of the condensing units of the Split
models.
N.B. For an optimal use of the Condensing unit it is advisable to connect it with an evaporating unit, asking
the distributor for the exact corresponding model. If an evaporator of a different brand or model is installed,
the installer has to check if its technical characteristics are in accordance with the dimensioning foreseen by
the manufacturer of the Condensing unit; that should not be the case, it is possible to execute the necessary
changes only after having consulted the manufacturer.

Evaporating units: See what is described as concerns the installation of the evaporator of the Split models.
