The (automatic) leak detection function is not by default activated and can only
start working when the additional refrigerant charge was input into the system's
logic (see [2‑14]).
The leak detection operation can be automated. By changing parameter [2‑88] to
chosen value, the interval time or the time until the next automatic leak detection
operation can be chosen. The parameter [2‑88] defines whether the leak detection
operation is executed one time (within [2‑65] days) or intermittent, respecting an
interval of [2‑65] days.
Availability of the leak detection function feature requires input of the additional
refrigerant charge amount immediately after finishing the charging. The input must
be executed before performing the test operation.
NOTICE
If a wrong value is input for the additional charged refrigerant weight, the accuracy
of the leak detection function will decrease.
INFORMATION
▪
The weighed and already recorded amount of additional refrigerant charge (not
the total amount of refrigerant present in the system) must be entered.
▪
When the height difference between indoor units is ≥50/40 m, the leak detection
function can not be used.
When the leak detection function was initially not required, but its activation is
wanted at a later moment, input the additional refrigerant charge into the system's
logic.
Executing the leak detection function one time at site can also be done by
following procedure.
1 Push BS2 one time.
2 Push BS2 one more time.
3 Push BS2 five seconds.
4 Leak detection function will start. To abort leak detection operation, push BS1.
Result: When the manual leak detection is finished, the result is shown on the
outdoor unit 7‑segment display. The indoor units are in locked state (centralised
control symbol). To return to normal state, push BS1.
