General warnings
Fundamental safety rules
After unpacking, make sure that all the components
are present. If not, contact your installer of your DAIKIN
affiliate office.
DAIKIN appliances must be installed by an authorised
installer who, on completion of the work, will release a
declaration of conformity to the client in respect of the
laws in force and the indications given by DAIKIN in the
instructions leaflet supplied together with the appliance.
These appliances have been designed both for
conditioning and/or heating environments and must
be destined for this use only and compatibly with their
performance characteristics.
DAIKIN EUROPE N.V. accepts no responsibility, either
contractual or extra-contractual, for any damage caused
to persons, animals of property as a result of incorrect
installation, adjustment or maintenance or improper use.
In case of water leaks, turn the master switch of the
system to "OFF" and close the water taps.
As soon as possible, call the DAIKIN technical service
department or else professionally qualified personnel
and do not intervene personally on the appliance.
The imbedded FWXM-series do not have a grill or
covering plate. Provide safety guards and air inlet/outlet
grills to prevent accidental contact with the device.
If the appliance is not used for a log period of time, the
following operations should be performed:
- Turn the master switch of the system to "OFF"
- Close the water taps
- If there is the risk of freezing, make sure that anti-freeze
has been added to the system otherwise empty the
system.
If the room temperature is too low or too high it is
damaging for the health and is also a useless waste of
energy.
Avoid prolonged contact with the direct air flow.
Do not leave the room closed for long periods.
Periodically open the windows to ensure a correct
change of air.
This instruction leaflet is an integral part of the
appliance and consequently must be kept carefully
and must ALWAYS accompany the appliance, even
when it is passed to a new owner or user or transferred
onto another system. If it is lost or damaged, please
contact the local DAIKIN technical service centre.
All repair or maintenance interventions must be
performed by the technical service department or by
professionally qualified personnel as foreseen in this
booklet. Do not modify or intervene on the appliance
as this could create dangerous situations and the
manufacturer will not be responsible for any damage
caused.
Danger from burns - take care when touching

8, and by people with reduced physical, sensory or
mental capabilities, or with no experience or necessary
knowledge, as long as they are monitored or after they
have received instructions on the safe use of the unit
and have understood the dangers involved.
Children must not play with the appliance.
The cleaning and maintenance that must be
performed by the user should not be carried out by
children without supervision.
It is forbidden to touch the appliance with wet hands
or body when barefoot.
It is forbidden to carry out any cleaning before having
disconnected the appliance from the electricity mains
supply by turning the system master switch to "OFF".
It is forbidden to modify the safety or adjustment

Positioning the unit
Installation modes
Avoid installing the unit in proximity to:
- positions subject to exposure to direct sunlight;
- in proximity to sources of heat;
- in damp areas or places with probable contact with
water;
- in places with oil fumes
- places subject to high frequencies.
Make sure that:
- the wall on which the unit is to be installed is strong
enough to support the weight;
- the part of the wall interested does not have pipes or
electric wires passing through;
- the interested wall is perfectly flat;
- there is an area free of obstacles which could interfere
with the inlet and outlet air flow;
- the installation wall is preferably an outside perimeter
wall to allow the discharge of the condensation outside;
- in case of ceiling installation (FWXM-series) the airflow is
not directed towards persons.
The following descriptions of the various mounting phase
and the relative designs refer to a version of the machine
with fixtures on the left.
The operations for the mounting of machines with fixtures
on the right are exactly the same.
Only the images are to be considered as a mirror image.
To ensure that the installation is performed correctly and
that the appliance will perform perfectly carefully follow the
instructions indicated in this manual. Failure to respect the
rules indicated not only can cause malfunctions of the
appliance but will also invalidate the warranty and hence
DAIKIN EUROPE N.V. shall not respond for any damage to
persons, animals or property.
Minimum installation distances
Figure indicates the minimum mounting distances
between the wall-mounted cooler-convector and furniture
present in the room.

Machine body
When mounting on the floor with support feet, refer to the
individual instructions leaflets supplied and the relative
manual for the mounting of the feet.
Using the paper template, trace the position of the two
fixing brackets on the wall. Use a suitable drill to make the
holes with and insert the toggle bolts (2 for each bracket);
fix the two brackets. Do not over-tighten the screws so
that the brackets can be adjusted with a spirit level.
Fully tighten the four screws to block the two brackets.
Check the stability by manually moving the brackets to the
right and to the left, up and down.
Mount the unit, checking that it fits correctly onto the
brackets and checking that it is stable.
Note: to facilitate the connection of the pipes to the fancoil
connections, install a built-in box at the outlet of the pipes
themselves.
The correct position of the box is indicated on the
installation template.

INSTALLATION
Horizontal or ceiling installation (FWXM-series)
Using the paper template, trace on the ceiling the position
of the two fixing brackets and the two rear screws. Using a
suitable drill, make the holes and insert the toggle bolts (2
for each bracket); fix the two brackets. Do not over-tighten
the screws. Position the machine on the two brackets,
keeping it in position and then fix the two screws into the
rear toggle bolts, one on each side.
Make sure that there is sufficient inclination of the unit
towards the drainage pipe to facilitate the water drainage.
Fully tighten all 6 fixing screws.
For installation of the FWXM-series, horizontal
condensation collection basin accessory kits are available
EKM(10/15/20)COH.
The installation of FWXV-series units in horizontal position
is prohibited.
Carefully check the inclination of the exhaust pipe.
Any counterslope of the discharge line can cause
water leakage

NB: the nominal diameter, unless otherwise indicated,
always refers to the internal diameter.
To avoid the formation of surface condensation, it is
always recommended to install electric valve kits, except
in the case where an electrical control (eg electrothermal
head) is provided upstream of the appliance. The choice
and sizing of the hydraulic lines must be made by an
expert who must operate according to the rules of good
technique and the laws in force, taking into account that
undersized pipes cause a malfunction.
To make the connections:
- position the hydraulic lines
- tighten the connections using the “spanner and
counter spanner” method
- check for any leaks of liquid
- coat the connections with insulating material.
The hydraulic lines and joints must be thermally
insulated.
Avoid partially insulating the pipes.
Do not over-tighten to avoid damaging the insulation.
Use hemp and green paste to seal the threaded
connections; the use of Teflon is advised when there is
anti-freeze in the hydraulic circuit.
