NOTICE

Improper  installation  or  attachment  of  equipment  or
accessories  could  result  in  electric  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.

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

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 aluminium fins of the unit.

NOTICE

▪ 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

In Europe, EN378 provides the necessary guidance for this logbook.

1.3.2

Installation site

▪ Provide  sufficient  space  around  the  unit  for  servicing  and  air

circulation.

▪ Make sure the installation site withstands the weight and vibration

of the unit.

▪ Make  sure  the  area  is  well  ventilated.  Do  NOT  block  any

ventilation openings.

▪ Make sure the unit is level.

Do NOT install the unit in the following places:

▪ In potentially explosive atmospheres.

▪ In  places  where  there  is  machinery  that  emits  electromagnetic

waves.  Electromagnetic  waves  may  disturb  the  control  system,
and cause malfunction of the equipment.

▪ In  places  where  there  is  a  risk  of  fire  due  to  the  leakage  of

flammable  gases  (example:  thinner  or  gasoline),  carbon  fibre,
ignitable dust.

▪ In  places  where  corrosive  gas  (example:  sulphurous  acid  gas)  is

produced. Corrosion of copper pipes or soldered parts may cause
the refrigerant to leak.

Instructions for equipment using R32 refrigerant

If applicable.

WARNING

▪ Do NOT pierce or burn.

▪ Do  NOT  use  means  to  accelerate  the  defrosting

process  or  to  clean  the  equipment,  other  than  those
recommended by the manufacturer.

▪ Be  aware  that  R32  refrigerant  does  NOT  contain  an

odour.

WARNING

The appliance shall be stored so as to prevent mechanical
damage and in a well-ventilated room without continuously
operating  ignition  sources  (example:  open  flames,  an
operating  gas  appliance  or  an  operating  electric  heater)
and have a room size as specified below.

NOTICE

▪ Do NOT re-use joints which have been used already.

▪ Joints  made  in  installation  between  parts  of  refrigerant

system shall be accessible for maintenance purposes.

WARNING

Make  sure  installation,  servicing,  maintenance  and  repair
comply  with  instructions  from  Daikin  and  with  applicable
legislation  (for  example  national  gas  regulation)  and  are
executed only by authorised persons.

Installation space requirements

NOTICE

▪ Pipework shall be protected from physical damage.

▪ Installation of pipework shall be kept to a minimum.

WARNING

If  appliances  contain  R32  refrigerant,  the  floor  area  of  the
room  in  which  the  appliances  are  installed,  operated  and
stored  MUST  be  larger  than  the  minimum  floor  area
defined in table below A (m

2

). This applies to:

▪ Indoor  units 

without

  a  refrigerant  leakage  sensor;  in

case  of  indoor  units 

with

  refrigerant  leakage  sensor,

consult the installation manual

▪ Outdoor  units  installed  or  stored  indoors  (e.g.  winter

garden, garage, machinery room)

▪ Pipework in unventilated spaces
