Unit Activation
To ensure stepless air-flow control using the Unicon sensor
and to prevent the fan output cycling, we recommend setting
the frequency inverter start-up and run-down ramps to 180
s (Danfoss frequency inverter –parameters 3-41 and 3-42).
If the system is equipped with a PLC controller for compressor
output control, it is necessary to follow the provided Operat-
ing Instructions, especially to check and remove possible
failure messages. The controller has already been set and the
parameters need not be adjusted, with only some exceptions.
Now it is possible to switch the unit to RUN mode (see chapter
4.1 Main Switch).
Check the fan current consumption in each operating
mode. If higher than Imax (see motor rating plate), it must
be decreased (e.g. by decreasing the max. frequency of the
frequency inverter).
Current Date and Time Settings
According to the customer's requirements, set the desired
temperature and humidity at full operating mode (e.g. 31°C,
50%) and at reduced operating mode (e.g. 28°C, 70%). It is
also necessary to set the time schedule for full operating mode
(time of swimming pool use, e.g. 9.00-20.00 h).
Outside this time, the unit is operated in reduced operating
mode.
If the air-handling unit is equipped with the Unicon constant
air flow sensor, set this required air flow in the Carel control-
ler menu.
The swimming-pool unit should be constantly in operation,
except for service and maintenance periods.
The system is filled with a calculated quantity of coolant in
the factory.

Coolant Handling
The used HFC type coolants (e.g. R404A, R407C, R410A,...)
fall into the category of monitored greenhouse substances
in accordance with European Parliament and Council Direc-
tive EC 842/2006 on F-gases (Art. 3, par. 6) and CZ Act no.
483/2008 Sb on air conservation. The user of a cooling
device containing ≥3kg of coolant is obliged to keep records
on results of periodic leak tests, the so-called Cooling Device
Service Book, which must include the following data:
n
Volume and type of coolant used during unit installation
n
Results of performed preventive checks, especially the
results of leakage tests
n
Volume of added or drained coolant when performing
maintenance or during unit operation or liquidation.
The records must include identification of the personnel or
company who performed the maintenance or servicing. Any
checks or intervention into the cooling circuit may only be
performed by personnel certified by the Ministry of Health
of the Czech Republic. On request, the user must submit the
logs to the appropriate control authority.
The frequency of checks is determined by the volume of
coolant:
up to 30 kg ..... once a year
up to 300 kg ... twice a year
If a leak is found, it must be removed immediately. Repeat
leakage tests of the circuit must be performed one month
after the repair to verify the repair's efficiency.
