FXMQ-A
VRV system air conditioner
3P701545-1 – 2022.07

CAUTION

This  equipment  is  NOT  intended  for  use  in  residential
locations  and  will  NOT  guarantee  to  provide  adequate
protection to radio reception in such locations.

Duct installation (see 

"12.2.2 Guidelines when installing the

ducting"

 [

4

 12])

CAUTION

In  case  of  installation  WITHOUT  the  duct  on  inlet  side,
make sure to install the air filter. For more information refer
to the option list of the indoor unit.

CAUTION

▪ Make sure the installation of the duct does NOT exceed

the setting range of the external static pressure for the
unit. Refer to the technical datasheet of your model for
the setting range.

▪ Make  sure  to  install  the  canvas  duct  so  vibrations  are

NOT  transmitted  to  the  duct  or  ceiling.  Use  a  sound-
absorbing material (insulation material) for the lining of
the  duct  and  apply  vibration  insulation  rubber  to  the
hanging bolts.

▪ When  welding,  make  sure  NOT  to  spatter  onto  the

drain pan or the air filter.

▪ If the metal duct passes through a metal lath, wire lath

or  metal  plate  of  the  wooden  structure,  separate  the
duct and wall electrically.

▪ Install the outlet grille in a position where the airflow will

not come into direct contact with people.

▪ Do NOT use booster fans in the duct. Use the function

to  adjust  the  fan  rate  setting  automatically  (see

"16 Configuration"

 [

4

 17]).

Electrical installation (see 

"14 Electrical installation"

 [

 15])

WARNING

ALWAYS use multicore cable for power supply cables.

WARNING

▪ All  wiring  MUST  be  performed  by  an  authorised

electrician  and  MUST  comply  with  the  applicable
legislation.

▪ Make electrical connections to the fixed wiring.

▪ All  components  procured  on-site  and  all  electrical

construction  MUST  comply  with  the  applicable
legislation.

WARNING

▪ If  the  power  supply  has  a  missing  or  wrong  N-phase,

equipment might break down.

▪ Establish  proper  earthing.  Do  NOT  earth  the  unit  to  a

utility  pipe,  surge  absorber,  or  telephone  earth.
Incomplete earthing may cause electrical shock.

▪ Install the required fuses or circuit breakers.

▪ Secure  the  electrical  wiring  with  cable  ties  so  that  the

cables  do  NOT  come  in  contact  with  sharp  edges  or
piping, particularly on the high-pressure side.

▪ Do  NOT  use  taped  wires,  stranded  conductor  wires,

extension  cords,  or  connections  from  a  star  system.
They can cause overheating, electrical shock or fire.

▪ Do  NOT  install  a  phase  advancing  capacitor,  because

this  unit  is  equipped  with  an  inverter.  A  phase
advancing  capacitor  will  reduce  performance  and  may
cause accidents.

WARNING

Use  an  all-pole  disconnection  type  breaker  with  at  least
3  mm  between  the  contact  point  gaps  that  provides  full
disconnection under overvoltage category III.

WARNING

If the supply cord is damaged, it MUST be replaced by the
manufacturer,  its  service  agent  or  similarly  qualified
persons in order to avoid a hazard.

WARNING

Prevent hazards due to inadvertent resetting of the thermal
cut-out:  power  to  this  appliance  MUST  NOT  be  supplied
through  an  external  switching  device,  such  as  a  timer,  or
connected to a circuit that is regularly turned ON and OFF
by the utility.
