FUNDAMENTAL SAFETY RULES
U I A
When operating equipment involving the use of electricity and water, a number of fundamental safety rules must be observed,
namely:
The appliance is not intended for use by persons (includ-
ing children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concern-
ing use of the appliance by a person responsible for their
safety.
Children must be supervised to ensure they do not play
with the appliance.
Installation must only be performed by qualified person-
nel.
Do not touch the unit with bare feet or with wet or damp
parts of the body.
Never perform any cleaning operations before having
disconnected the unit from the mains power supply,
moving the main switch to the “off” position.
Do not modify safety or control devices without authori-
sation and instructions from the manufacturer.
Do not pull, detach or twist the electrical cables coming
from the unit, even when disconnected from the mains
electricity supply.
Do not introduce objects or substances through the air
outlet and intake grills.
Do not open doors or panels providing access to the
internal parts of the appliance, without first having
moved the main switch to “off”.
Do not dispose of, abandon or leave within reach of chil-
dren packaging materials, as they may represent a haz-
ard.
Do not sit or stand on the appliance and/or rest any type
of object on top of it.
The outside components of the appliance may reach
temperatures exceeding 70°
GENERAL WARNINGS
After having removed the packing, check that the con-
tents are intact and complete.
In the event of discrepancies, contact the service centre
that sold the appliance.
The appliances must be installed by authorised personnel,
who at the end of the work shall issue a declaration of
conformity in compliance with the legislation in force and
with the instructions provided in the booklet supplied with
the appliance.
These appliances have been designed for cooling and
heating rooms and must be used in applications compat-
ible with their performance characteristics.
Incorrect installation, adjustment and maintenance or
improper use absolve the manufacturer from all liability,
whether contractual or otherwise, for damage to people,
animals or things.
In the event of water leaks, move the main system switch
to the “off” position and close the water taps.
Contact the technical service or a qualified professional

CONDENSATE DRAIN
I A
The condensate drain line must be suitably sized (pipe with
a minimum inside diameter of 16 mm) and the pipe laid out
as to ensure a minimum slope of 1% along the entire line.
For vertical installation, the drain line is connected directly to
the drain pan, located at the bottom of the side frame,
underneath the water connections.
For horizontal installation, the drain line is connected to the
drain pipe already fitted on the unit.
For horizontal installation of DLMO versions, the horizontal
condensate collection pan kits are available as accessories.
- If possible, discharge the condensate directly into a gutter
or a storm water drain.
- If draining into the sewers, a drain trap should be fitted to
prevent bad odours from drifting back into the rooms.
The bend in the drain trap must be lower than the conden-
sate collection pan.
- If discharging the condensate into a container, this must
be open and the drain pipe must not be immersed in the
water, so as to avoid surface tension and backpressure
that would prevent correct drainage.
- If needing to overcome a raised section that wold prevent
condensate drainage, a pump must be installed:
- for vertical installation, fit the pump underneath the side
drain pan;
- for horizontal installation, the position of the pump should
be determined according to specific needs.
These pumps are widely available on the market.
In any case, following installation check correct condensate
drainage by pouring very slowly (around 1/2 l of water in
around 5-10 minutes) into the collection pan.

fitting and secure it in place.
Make sure that the drip guard is installed correctly.
WATER CONNECTIONS
I A
The choice and sizing of the water lines is the responsibility
of the designer, who must apply best working practice and
comply with the legislation in force, also considering that
undersized lines will lead to poor performance.
To make the connections:
- position the water lines
- tighten the connections using two spanners in opposite
directions
- check for any leaks
- cover the connections with insulating material
The water lines and the joints must be thermally insulated.
Make sure the pipes are completely insulated.
Avoid over-tightening so as to not damage the insulation.
To ensure water tightness of threaded connections, use
plumber’s hemp and green paste; Teflon tape is recom-
mended when antifreeze is added to the water circuit.

Assembling the condensate drain pipe on horizontal
versions
To assemble the horizontal drain pan on DLMO versions,
see the instructions supplied with the horizontal pan kit.
- make sure that the “L” pipe and the rubber hose are cor-
rectly connected to the pan.
- insert the side of the unit, keeping the pipe held against
the front grill.
- close the side, making sure the pipe remains secured in
the groove provided on the side.
- If necessary, cut the plastic tube C for the condensate
drain and fix the painted pipe to the plastic tube with the
supplied clamp so that the knot of the clamp is facing
away from the cabinet to keep the pipe to the right slope
for the correct condensate drain. (see
fig. 1
)
N.B. warnings for horizontal installation:
- make sure that the unit is perfectly level, or with a slight
slope towards the condensate drain;
- carefully insulate the outlet and return pipes all the way to
the unit, so as to prevent condensate from dripping out-
side of the collection pan;
- insulate the entire condensate pan drain pipe.

TIPS ON SAVING ENERGY
I A
- Keep the filters clean at all times;
- where possible, keep the doors and windows in the air-
conditioned room closed;
- where possible, in cooling operation limit exposure of the
air-conditioned room to direct sunlight (use curtains, shut-
ters, etc.).
Fault
Possible cause
Solution
The fan starts after a delay from changing the
temperature settings or function.
The circuit valve takes some time to open and
let hot or cold water circulate in the appliance.
Wait 2 or 3 minutes for the circuit valve to
open.
The fan does not start.
No hot or cold water in the system.
Make sure that the boiler or water chiller are
operating.
The fan does not start active even when there
is hot or cold water in the circuit.
The water valve remains closed
Remove the valve body and check if water
starts circulating.
Check valve operation by powering it sepa-
rately at 230 V.
If the valve is activated, the problem may lie in
the electronic controller.
The fan motor is blocked or burnt out.
Check the motor windings and make sure the
fan can spin freely.
The microswitch that stops the fan when
opening the filter grill does not close correctly.
Make sure that when closing the grill, the
microswitch contact is activated.
Incorrect electrical connections.
Check the electrical connections.
Water leaks from the appliance in heating
mode.
Leaks from the system water connections.
Check the leaks and fully tighten the connec-
tions.
Leaks from the valves.
Check the gaskets.
Dew forms on the front panel.
Heat insulation detached.
Make sure that the heat insulation/sound-
proofing is positioned correctly, especially at
the front above the finned coil.
There are droplets of water on the air outlet
louvers.
When relative humidity inside the room is
quite high (>60%), condensate may form,
especially at low fan speed.
When the relative humidity falls, the phenom-
enon will disappear.
In any case, the formation of some droplets of
water inside the appliance does not indicate a
malfunction.
Water leaks from the appliance in cooling
mode only.
The condensate pan is blocked.
Slowly pour a bottle of water into the bottom
of the coil to check drainage; if necessary,
clean the pan and/or increase the slope of the
drain pipe.
The condensate drain is not sloped down-
wards enough for correct draining.
The connection pipes and valves are not
properly insulated.
Check the insulation on the pipes.
The appliance is very noisy.
The fan is touching the structure.
Check the filters and clean them if necessary.
The fan is unbalanced.
An unbalanced fan will cause excessive vibra-
tions on the unit: replace the fan.
Check the filters and clean them if necessary
Clean the filters
The louvers stay open.
Possible obstruction blocking rotation.
Remove the obstruction, power off the appli-
ance, wait 2 minutes and power the appliance
on again. The louvers close correctly.
