FTXM-V Series
1-3 For the installer
1-3-1 General
If you are NOT sure how to install or operate the unit, contact
your dealer.
The manual contains specific information about the required
qualification of the working personnel for maintenance, service
and repair operations.
Every working procedure that affects safety should only be
carried out by competent persons.
Examples for such working procedures are:
• Breaking into the refrigerating circuit
• Opening of sealed components
• Opening of ventilated enclosures
DANGER: RISK OF BURNING
• Do NOT touch the refrigerant piping, water piping or
internal parts during and immediately after operation.
It could be too hot or too cold. Give it time to return to
normal temperature. If you must touch it, wear
protective gloves.
• Do NOT touch any accidental leaking refrigerant.
WARNING
Improper installation or attachment of equipment or
accessories could result in electrical shock, short-
circuit, leaks, fire or other damage to the equipment.
Only use accessories, optional equipment and spare
parts made or approved by Daikin.
WARNING
Make sure installation, testing and applied materials
comply with applicable legislation (on top of the
instructions described in the Daikin documentation).
CAUTION
Wear adequate personal protective equipment
(protective gloves, safety glasses,...) when installing,
maintaining or servicing the system.
WARNING
Tear apart and throw away plastic packaging bags so
that nobody, especially children, can play with them.
Possible risk: suffocation.
WARNING
Provide adequate measures to prevent that the unit can
be used as a shelter by small animals. Small animals
that make contact with electrical parts can cause
malfunctions, smoke or fire.

CAUTION
Do NOT touch the air inlet or aluminum fins of the unit.
CAUTION
• Do NOT place any objects or equipment on top of the
unit.
• Do NOT sit, climb or stand on the unit.
NOTICE
Works executed on the outdoor unit are best done
under dry weather conditions to avoid water ingress.
In accordance with the applicable legislation, it might be
necessary to provide a logbook with the product containing at
least: information on maintenance, repair work, results of tests,
stand-by periods,...
Also, at least, following information MUST be provided at an
accessible place at the product:
• Instructions for shutting down the system in case of an
emergency
• Name and address of fire department, police and hospital
• Name, address and day and night telephone numbers for
obtaining service
• ISO 5149 provides the necessary guidance for this logbook.
That after completion of field piping for split systems, the field
pipework should be pressure tested with an inert gas and then
vacuum tested prior to refrigerant charging, according to the
following requirements:
• The minimum test pressure for the low side of the system
should be the low side maximum allowable pressure and the
minimum test pressure for the high side of the system should
be the high side maximum allowable pressure, unless the high
side of the system cannot be isolated from the low side of the
system, in which case the entire system should be pressure
tested to the low side maximum allowable pressure.
• The test pressure after removal of the pressure source should
be maintained for at least 1 hour with no decrease of pressure
indicated by the test gauge, with test gauge resolution not
exceeding 5% of the test pressure.
• During the evacuation test, after achieving a vacuum level
equal to or less than the vacuum level specified in the manual,
the refrigeration system should be isolated from the vacuum
pump and the pressure should not rise above 1500 microns
within 10 minutes. The vacuum pressure level is specified in
the manual, and should be less than 500 microns, or the value
required for compliance with national and local codes and
standards, which may vary between residential, commercial,
and industrial buildings.
