[2-10]

Setting to enable or disable the external alarm output during the SV
unit test run.

This setting is only to be used during the test run of the SV unit when
a  ventilated  enclosure  is  used  as  a  safety  measure  of  the  SV  unit
and an external alarm is added as an additional measure. During the
SV unit test run, which is started by setting [2-3] to "1", the external
fan and external alarm are both active. To disable the external alarm
during the airflow rate measurements, change setting [2-10] to "1".

Once  the  SV  unit  test  run  is  finished  (setting  [2-3]  changed  to  "0"),
setting [2-10] automatically returns to its default value "0".

Mode 2: default field settings

The  table  below  shows  the  default  field  settings  for  A1P  and  A2P
(A2P only for SV6A and SV8A).

In  case  of  wrong  field  settings  made  during  the  configuration
process, it is recommended to revert to the default field settings and
then restart the configuration.

checklist.

Next 

to 

the

commissioning  instructions  in  this  chapter,  a  general
commissioning  checklist  is  also  available  on  the  Daikin
Business Portal (authentication required).

The  general  commissioning  checklist  is  complementary  to
the  instructions  in  this  chapter  and  can  be  used  as  a

hand-over to the user.

17.1

Checklist before commissioning

1

After the installation of the unit, check the items listed below.

2

Close the unit.

3

Power up the unit.

You  have  read  the  complete  installation  and  operation
instructions described in the 

installer and user reference

guide

.

The SV

 unit

 is properly mounted.

The 

field  wiring

  has  been  carried  out  according  to  the

instructions  described  in  this  document,  according  to  the
wiring  diagram  and  according  to  the  applicable  national
wiring legislation.

The 

drain  piping

  is  properly  installed  and  insulated,  and

drainage flows smoothly. Check for water leaks.

Possible consequence: 

condensate water might drip.

There are NO 

missing phases

 or 

reversed phases

.

The  system  is  properly 

earthed

  and  the  earth  terminals

are tightened.

The 

fuses

  or  locally  installed  protection  devices  are

installed according to this document, and have NOT been
bypassed.

The 

power  supply  voltage

  matches  the  voltage  on  the

identification label of the unit.

There  are  NO 

loose  connections

  or  damaged  electrical

components in the switch box.

In  case  no  safety  measures  are  required,  the  following
measures are correctly applied:

▪ No safety measures are attached.

▪ The correct field settings are made.

In case an external alarm is required, the following safety
measures are correctly applied:

▪ The external alarm is connected and powered.

▪ The correct field settings are made.

In  case  natural  ventilation  is  required  as  safety  measure,
the following safety measures are correctly applied:

▪ Partition  between  rooms  for  natural  ventilation  meets

the requirements.

▪ The correct field settings are made.

In  case  a  ventilated  enclosure  is  required,  the  following
safety measures are correctly applied:

▪ The ducting is properly installed and insulated.

▪ The extraction fan is connected and powered.

▪ The air inlet (damper) is not obstructed.

▪ The correct field settings are made.

Also follow the outdoor unit's checklist. See the installation
and operation manual delivered with the outdoor unit.

SV unit test run

17.2.1

About the SV unit test run

The  SV  unit  test  run  has  to  be  performed  on  all  SV  units  in  the
system, before the test run of the outdoor unit. The SV unit test run
has  to  confirm  that  the  required  safety  measures  are  properly
installed.  Even  when  no  safety  measures  are  required,  it  is
necessary  to  perform  this  SV  unit  test  run  and  confirm  the  result,
because the test run of the outdoor unit checks this confirmation for
all SV units in the system.

Depending  on  the  safety  measure  and  the  configuration  of  the  SV
unit,  it  is  required  to  perform  the  SV  unit  test  run  on  a  specific  SV
unit of the system.

Note: 

Do not perform a SV unit test run on more than one SV unit at

a time.
