07C2V3
Daikin Altherma monobloc compact outdoor unit
4P598847-1 – 2019.10

The outdoor unit is installed 5 m below the highest point in the water
circuit. The total water volume in the water circuit is 100 l.

No actions or adjustments are required.

Example 2

The outdoor unit is installed at the highest point in the water circuit.
The total water volume in the water circuit is 350 l. The concentration
of propylene glycol is 35%.

Actions:

▪ Because  the  total  water  volume  (350  l)  is  more  than  the  default

water volume (105 l), the pre-pressure must be decreased.

▪ The required pre-pressure is:

Pg = (0.3+(H/10)) bar = (0.3+(0/10)) bar = 0.3 bar

▪ The  corresponding  maximum  water  volume  at  0.3  bar  is  150  l.

(See the graph in the chapter above).

▪ Because  350  l  is  more  than  150  l,  the  expansion  vessel  is  NOT

appropriate  for  the  installation.  Therefore  the  system  requires  an
external expansion vessel.

Preparing electrical wiring

5.4.1

About preparing electrical wiring

INFORMATION

Also  read  the  precautions  and  requirements  in  the
"General safety precautions" chapter.

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

▪ 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

ALWAYS use multicore cable for power supply cables.

5.4.2

About preferential kWh rate power supply

Electricity  companies  throughout  the  world  work  hard  to  provide
reliable  electric  service  at  competitive  prices  and  are  often
authorized  to  bill  clients  at  benefit  rates.  E.g.  time-of-use  rates,
seasonal rates, Wärmepumpentarif in Germany and Austria, ...

This  equipment  allows  for  connection  to  such  preferential  kWh  rate
power supply delivery systems.

Consult  with  the  electricity  company  acting  as  provider  at  the  site
where  this  equipment  is  to  be  installed  to  know  whether  it  is
appropriate to connect the equipment in one of the preferential kWh
rate power supply delivery systems available, if any.

When  the  equipment  is  connected  to  such  preferential  kWh  rate
power supply, the electricity company is allowed to:

▪ interrupt power supply to the equipment for certain periods of time;

▪ demand  that  the  equipment  only  consumes  a  limited  amount  of

electricity during certain periods of time.

The  domestic  hot  water  tank  is  designed  to  receive  an  input  signal
by  which  it  switches  the  outdoor  unit  into  forced-off  mode.  At  that
moment, the compressor will not operate.

The  wiring  to  the  unit  is  different  depending  on  whether  the  power
supply is interrupted or not.

supply activation,
power supply is NOT
interrupted. The
outdoor unit is turned
off by the control.

Remark:

 The

electricity company
must always allow the
power consumption
of the hydro part of
the outdoor unit (and
of the domestic hot
water tank, if part of
the system).

During preferential

supply activation,
power supply is
interrupted
immediately or after
some time by the
electricity company.
In this case, the
hydro part of the
outdoor unit (and the
control box, if part of
the system) must be
powered by a
separate normal
