Abnormal
completion

Refer to 

"8.4.3 Correcting after abnormal

completion of the test run" on page 36

 to take

actions for correcting the abnormality. When
the test operation is fully completed, normal
operation will be possible after 5 minutes.

8.4.3

Correcting after abnormal completion of
the test run

The test operation is only completed if there is no malfunction code
displayed.  In  case  of  a  displayed  malfunction  code,  perform
correcting actions as explained in the malfunction code table. Carry
out  the  test  operation  again  and  confirm  that  the  abnormality  is
properly corrected.

INFORMATION

If a malfunction occurs, the error code is displayed on the
user interface of the indoor unit.

INFORMATION

Refer  to  the  installation  manual  of  the  indoor  unit  for
detailed malfunction codes related to indoor units.

Hand-over to the user

Once the test run is finished and the unit operates properly, please
make sure the following is clear for the user:

▪ Make  sure  that  the  user  has  the  printed  documentation  and  ask

him/her to keep it for future reference. Inform the user that he can
find the complete documentation at the URL mentioned earlier in
this manual.

▪ Explain the user how to properly operate the system and what to

do in case of problems.

▪ Show the user what to do for the maintenance of the unit.

Maintenance and service

NOTICE

Maintenance  MUST  be  done  by  an  authorized  installer  or
service agent.

We  recommend  performing  maintenance  at  least  once  a
year. However, applicable legislation might require shorter
maintenance intervals.

NOTICE

Applicable  legislation  on 

fluorinated  greenhouse  gases

requires  that  the  refrigerant  charge  of  the  unit  is  indicated
both in weight and CO

2

 equivalent.

Formula  to  calculate  the  quantity  in  CO

2

  equivalent

tonnes:

  GWP  value  of  the  refrigerant  ×  total  refrigerant

charge [in kg] / 1000

10.1

Overview: Maintenance and
service

This chapter contains information about:

▪ Preventing  electrical  hazards  when  maintaining  and  servicing  the

system

▪ The refrigerant recovery operation

10.2

Maintenance safety precautions

DANGER: RISK OF ELECTROCUTION

DANGER: RISK OF BURNING

NOTICE: Risk of electrostatic discharge

Before performing any maintenance or service work, touch
a metal part of the unit in order to eliminate static electricity
and to protect the PCB.

10.2.1

To prevent electrical hazards

When performing service to inverter equipment:

1

Do  NOT  open  the  electrical  component  box  cover  for
10 minutes after turning off the power supply.

2

Measure  the  voltage  between  terminals  on  the  terminal  block
for power supply with a tester and confirm that the power supply
is  shut  off.  In  addition,  measure  points  as  shown  in  the  figure,
with a tester and confirm that the voltage of the capacitor in the
main circuit is less than 50 V DC.

C+

3

To  prevent  damaging  the  PCB,  touch  a  non-coated  metal  part
to  eliminate  static  electricity  before  pulling  out  or  plugging  in
connectors.

4

Pull  out  junction  connectors  for  the  fan  motors  in  the  outdoor
unit before starting service operation on the inverter equipment.
Be  careful  not  to  touch  the  live  parts.  (If  a  fan  rotates  due  to
strong  wind,  it  may  store  electricity  in  the  capacitor  or  in  the
main circuit and cause electric shock.)

Junction connector

X106A for M1F

5

After the service is finished, plug the junction connector back in.
Otherwise  the  malfunction  code 

  will  be  displayed  and

normal operation will not be performed.

For  details  refer  to  the  wiring  diagram  labelled  on  the  back  of  the
service cover.

Pay attention to the fan. It is dangerous to inspect the unit while the
fan is running. Make sure to turn off the main switch and to remove
the fuses from the control circuit located in the outdoor unit.

10.3

Checklist for yearly maintenance
of the outdoor unit

Check the following at least once a year:

▪ Heat exchanger

The heat exchanger of the outdoor unit can get blocked up due to
dust,  dirt,  leaves,  etc.  It  is  recommended  to  clean  the  heat
exchanger  yearly.  A  blocked  heat  exchanger  can  lead  to  too  low
pressure or too high pressure leading to worse performance.
