ent "Cxx" parameters, and then use
���
to access and
validate the values and the
keys to modify these
parameters in accordance with the above tables.
Horizontal air discharge assembly
0.- Check to see the packing is not damaged. Unblock the
motor and make sure the slits open and close correctly
by applying force.
1.- Disconnect power supply to the unit.
2.- Install the lower support supplied, as in figure 1. Fasten
the support with the self-threading screws of the acces-
sory.
Cut four 400 mm. long strips of the 24 x 24 mm. gasket.
Place on both verticle sides of the damper and the panel
to avoid air leaks.
3.- Lean the dampers on the previously fitted support, with
the motor at the point nearest the control panel (Fig. 7).
4.- Install the top support and fasten it to the chassis of the
unit by means of the drilled holes and self-threading
screws supplied (Fig. 7).
5.- Fasten the dampers to the lower and top supports with
the self-threading screws supplied (Fig. 7).
6.- Open the control panel and remove the roof cover.
7.- Fit the CP1 control unit in the DIN guide on the X3 con-
necting strip side. On models RTH, also install relay
RRV1 (Fig. 8).
8.- Move contactors KM1 and KM2 to attach the side aux-
iliary contacts supplied.
9.- Screw the high pressure intake switch on to the condens-
ing unit output and check for leaks. But first unscrew and
remove the plugs that protect same.
10.- Connect the pressure switch hose and fasten it by means
of the clamps supplied along with the existing wiring
cables.
11.- Insert the pressure switch hose through the hole on the
separator panel, and install the 28 ø wall hole guide
supplied.
12.- Connect the pressure switch hoses to control unit
CP1.
13.- Remove the damper motor cover, insert the damper
hoses and connect as indicated on the corresponding
diagram (Fig. 7).
14.- Drill a 22 Ø hole and insert the wall hole guide for the
damper motor hose.
15.- Connect all cables supplied, in accordance with the cor-
responding wiring diagram.
16.- Turn main power supply on and program the control
unit.
17.- Close all panels.
Checking
1.- Program the thermostat in the winter cycle (pumps only),
start the compressors and make sure the dampers open
completely.
2.- Turn the unit off and program the thermostat in the sum-
mer cycle.
3.- Start the compressors and check to be sure that when the
pressure begins to rise above the programmed 26 bars,
the dampers begin to close.
Once this pressure is reached, the dampers open to a
specific position, depending upon the outdoor tempera-
ture. With a very low outdoor temperature, the dampers
should be closed.
