10.2.4 Checking the refrigerant circuit
• Check to ensure that the stop valves on the gas and liquid
lines are fully open.
• Check the inside of the unit for refrigerant leakage. If there is
a refrigerant leak, please contact Firebird.
• Do not touch any of the parts by hand at the discharge gas
side, since the compressor chamber and the pipes at the
discharge side are heated higher than 90°C.
• DO NOT PUSH THE BUTTON OF THE MAGNETIC SWITCH(ES),
it will cause a serious accident.
• Confirm that the leakage of the refrigerant does not exist.
The flare nuts are sometimes loosened by vibration during
transportation
10.2.5 Test and check
Finally, test and check the following items:
• Water leakage
• Refrigerant leakage
• Electrical connection
10.3 Commissioning Procedure
10.4 Test Run / Air Purge
This procedure is valid regardless of what options are
on the module.
• When installation is complete and all necessary settings
(dip-switches in PCBs and user controller configuration) have
been carried out, close the electrical box and place
the cabinet as shown in the manual.
• Make the start-up wizard configuration in the user controller.
• Make a test run as shown in item “10.4 Test run / air purge”.
• After test run is completed, start the entire unit or the
selected circuit by pressing the OK button.
Initial start-up at low outdoor ambient temperatures
During commissioning and when water temperature is very low,
it is important for the water to be heated gradually. Additional
optional function can be used for starting at low water
temperature conditions: Screed drying function:
– The screed function is used exclusively for the process of
drying a newly applied screed to the floor heating system.
– The process is based on EN-1264 part 4.
– When user activates screed function, the water set point
follows a predetermined schedule:
1 Water set point is kept constant at 25ºC for 3 days
2 Water set-point is set to the maximum heating supply
temperature (but always limited to
≤
55ºC) for 4 days.
Test run is a working mode used when commissioning the
installation. Air purge function drives the pump in a way for
evacuating air bubbles in the installation.
A menu with specific function for commissioning appears by
pressing the menu+back buttons for 3 seconds at the installer
menu (OK+back buttons).
This menu shows the following test to be launched:
• Unit test run
• Air purge
• Screed drying
CAUTION
• Heating at lower water temperatures (approximately 10ºC to
15ºC) and lower outdoor ambient temperatures (<10ºC) can
be damaging to the heat pump when defrosting.
• As a result, Heating up to 15ºC when outdoor temperature is
lower than 10ºC is performed by the Electrical Heater.
NOTE
In case of Heater Forced OFF (by optional dip switch setting)
these condition is not performed and heating is performed by
Heat Pump. Firebird is not responsible for its operation.
CAUTION
It is recommended to start the unit (first power ON) with heater
forced OFF and compressor forced OFF (see “9.5 Setting of
DIP switches and RSW switches”). In order to circulate water
by water pump and remove possible air into the heater (check
heater completely filled).
