Installing The Internal Unit; Installing The External Unit - Ariston NIVOS Serie Instrucciones Para El Uso Y El Mantenimiento

1.3 Installing the internal unit

1. Push the piping, together with all cables, through the hole made
in the wall and hook the internal unit onto the top of the tem-
plate.
2. Shape the piping and cables well.
3. Push the lower part of the internal unit well up against the tem-
plate.
Make sure that:
a. The top and bottom hooks on the internal unit are securely fas-
tened onto the template.
b. The unit is fully horizontal.
If the appliance is not level, water may leak from it onto the floor.
c. The drain pipe is at the right gradient (minimum of 3 cm for each
metre in length).
d. The drain pipe stays at the bottom of the hole in the wall.
NOTES:
- Do not kink or constrict the internal unit piping in any way.
Avoid bends measuring less than 10 cm in radius.
- Do not bend the same section of the pipe too often as it could
kink after 3 attempts.
- Only remove the closing plugs from the internal unit piping im-
mediately prior to making the connections.
- Keep the condensation drain pipe at the bottom of the hole in
the wall, otherwise it could leak.
N.B.: Drill a hole in the wall that is 5-10 mm lower on the outside
than it is on the inside, so that the slope encourages downward
flow of the condensation.

1.4 Installing the external unit

The external unit must be moved and stored in an upright position,
to ensure suitable distribution of the oil in the refrigerant circuit and
prevent damage to the compressor.
Adhere to the procedure as described, and then start connecting
the piping and electrical wiring.
- Install the external unit in a place where the noise made by the
appliance and the expelled hot air cannot be a source of incon-
venience.
- Choose a place that does not obstruct free passage and where
the condensation water produced can easily be ducted to the
outside.
- Do not install the external unit in narrow areas which limit the air
flow, or in places exposed to strong winds.
For wall installation:
- install the unit securely onto a solid wall;
- pinpoint the most suitable position on the wall, allowing enough
room for any maintenance work to be carried out easily;
- fasten the brackets to the wall using rawlplugs suitable for the
type of wall in question (take care not to damage any wiring or
piping in conduits);
- use rawlplugs which can support a weight greater than that of
the external unit: during operation the machine vibrates and
should remain installed for years without the screws becoming
loose.
