UNICO INVERTER
ENGLISH
When installing models equipped with heating pump, if no condensate discharge was built into the wall, in order to drain the condensate
it will be necessary to drill a hole through the wall in the position shown on the template.
Preparing the condensate discharge
As far as machines equipped with a heating pump are concerned, connect the unit to the condensate discharge pipe (supplied)
by coupling it with the specific vent that is on the back of the machine (remove cap). When the max level is reached,
a solenoid valve ensures the condensate will flow out from the internal tray. For cold-only machines, connect the condensate
discharge pipe if you intend running the unit at low outdoor temperatures (lower than 23°C).
Since condensate drains by gravity, there must be a minimum slope of at least 3% at every point of the discharge line. Use a rigid
or flexible tube having an inside diameter of at least 16 mm.
If the line empties into a sewerage system, install a siphon before the point in which the pipe reaches the main discharge, at least
300 mm below the inlet from the unit.
If the drainpipe drains into a vessel (tank or other container), this container
should not be sealed and the drainpipe should not
remain immersed in the water.
The hole through which the condensate pipe passes should always slope towards the outside (see fig. 4).
The exact position in which to place the pipe inlet, as compared to the machine, is shown on the drilling template.
CAUTION:
make sure, in this case, that the water expelled outward does not damage or disturb persons or
property. During the winter this type of drainage may cause sheets of ice to form.
When the condensate drainage is fitted, pay much attention not to compress the rubber hose.
Assembly of the air ducts and external grids
After having drilled the holes, insert the plastic sheet supplied with the conditioner into them.
Since the sheet was made for 202 mm holes, you will have to cut off 130 mm from the long side of the sheet for the 162 mm holes.
The sheets must be 65 mm shorter than the length of the wall.
Roll the sheet and insert it into the hole (fig. 5), paying attention to the splicing line (fig. 5 ref. A),
which must always face
upwards.
Use an ordinary cutter for the foregoing operation (fig. 5).
To position the external grids, proceed as follows:
- Apply the seal (fig. 6 ref. B) to the wall flange (fig. 6 ref. A), ensuring it lines up with the outer edge of the flange as indicated in the
figure.
- Fix the two flanges using 2 pegs having a diameter of 6 and check that the two fixing holes are horizontal.
- Fit the small eyelet of the spring, with the long stem, on the cap pin (on both components) (fig. 7).
- Insert the two caps (with spring), on the front part of the external grid, on its two housings, pulling until it clicks (fig. 8) and couple
the two chains to the large eyelet of the spring.
- Using one hand, grip the two chains connected to the grid.
- Bend the external grids back, gripping them with your free hand where they bend, and insert your fingers inside the single fins (fig.
9).
- Insert your arm into the pipe until the grid protrudes completely outwards.
- Reopen the grid, being careful to keep your fingers inside the fins.
- Turn the grid until the fins are fully horizontal and tilted downwards.
- Pull the chain, tensioning the spring, and couple the chain ring to the pin of the inner flange through which the pipes pass (fig. 10).
- Use hand shears to cut off any excess chain links.
WARNING:
use exclusively the supplied grids, or grids with like characteristics.
