Daikin Altherma outdoor unit
4P501819-1 – 2017.08
16.3. Service mode operation
Refrigerant recovery operation/vacuuming operation is possible by
setting the unit in mode 2.
Refer to "Field settings by push buttons" on page 26 for details how to
set mode 2.
When vacuuming/recovery mode is used, check very carefully what
should be vacuumed/recovered before starting.
See installation manual of the indoor unit for more information about
vacuuming and recovery.
Vacuum method
1 When the unit is at standstill, set the unit in mode 2 as follows:
Push the BS1 MODE button for 5 sec, the H1P LED is on
w
2 Set the unit in mode 2-21:
Push the BS2 SET button 21 times until following LED
combination is reached:
3 Push the BS3 RETURN button to confirm setting 2-21 above.
4 Push the BS2 SET button to change the charge mode from OFF
(OFF) to ON (ON). LED indication should change as follows:
5 Push the BS3 RETURN button and the setting is defined.
6 Push the BS3 RETURN button again, to confirm this setting.
When confirmed, the indoor and outdoor unit expansion valves
will fully open. At that moment the H1P LED is ON (ON) and the
remote controller of all indoor units indicate TEST (test
operation) and (external control) and the operation will be
prohibited.
7 Evacuate the system with a vacuum pump.
8 Press BS1 MODE button and reset the setting mode 2.
Refrigerant recovery operation method
This should be done by a refrigerant reclaimer.
Follow the same procedure as for vacuuming method.
17. CAUTION FOR REFRIGERANT LEAKS
17.1. Introduction
The installer and system specialist shall secure safety against
leakage according to local regulations or standards. The
following standards may be applicable if local regulations are
not available.
This system uses R410A as refrigerant. R410A itself is an entirely
safe non-toxic, non-combustible refrigerant. Nevertheless care must
be taken to ensure that air conditioning facilities are installed in a
room which is sufficiently large. This assures that the maximum
concentration level of refrigerant gas is not exceeded, in the unlikely
event of major leak in the system and this in accordance to the local
applicable regulations and standards.
17.2. Maximum concentration level
The maximum charge of refrigerant and the calculation of the
maximum concentration of refrigerant is directly related to the
humanly occupied space in to which it could leak.
The unit of measurement of the concentration is kg/m
3
(the weight in
kg of the refrigerant gas in 1 m
3
volume of the occupied space).
Compliance to the local applicable regulations and standards for the
maximum allowable concentration level is required.
According to the appropriate European Standard, the maximum
allowed concentration level of refrigerant to a humanly space for
R410A is limited to 0.44 kg/m
3
.
Pay special attention to places, such as a basements, etc. where
refrigerant can stay, since refrigerant is heavier than air.
