14 Start up
the system start up has to be made by a competent staff with a
specific formation. The connection of the cooling circuit has to
be made by refrigeration engineer qualified and equipped with
the special license.
Following the correct hydraulic and electric installation of the
heat pump (HP), as specified in the previous pages, proceed as
follows.
14.1 Preliminary checks
Make sure that power cable of HP have a suitable section as
recommended in this manual, on the base of the power used
and the lenght of the cables themselves. The suitable electrical
device protections have to be inserted.
In the same way verify the signal cables of outside unit (sensors)
and of inside unit (sensors, flow switch, circulator, 3-way valve)
and and make sure they have the features demanded.
Control the Y filter is correctly connected in the return tube of
HP so tu avoid blocks or malfunction plate heat exchanger. Make
reference to this manual to use the right kind of tubes (diameter/
thickness) of the cooling circuit between the inside and outside
unit.
After having controlled the points mentioned above you can
proceed with the start up .
NOTE!
Be careful after the start up of the HP, the authomatic function
of oil heating will be activated (the duration depends on the
time necessary to bring to temperature the oil contained in the
compressor, so according the starting temperature).
NOTE!
If the inside and outside units are placed at different heights,
con with more than 3 meters difference, it is necessary to insert
some siphones to recover the every three meters in the cooling
line named “GAS”.
14.2 Test and start up
• Enter to menu “Assistance”: PRG --˃ G. Assistance --˃ g.
Manual management --˃ ASSISTANCE PASSWORD
Flow check:
• Screen Gg01 N04: Pump primary, set manual
function “MAN”.
Verify the correct water circulation of the circuit. After 5
start up attempts if the circulator doesn’t have the right
flow, an alarm red led will be lited up on the command
panel, and it is necessary to check the effective opening of
the hydraulic circuit (portcullis), air in the system or block
in Y filter can cause problems. Provide to remove it.
• Screen Gg01 N04: Pump primay, set authomatic
function “AUT”
Vent valves , split version.
Vent valves , monobloc version.
Compressor running:
Every HP is texted by the manufacturer before the supplying, in
any case we suggest to make short running, to not solicit the new
compressor too much. In this concern we suggest to use the rps
compressor manually at a medium value (50-60 rps) for one/two
hours at least.
