15.1.4 CHECKS ON THE WATER CONDENSED DIRECT EXPANSION CIRCUIT
Description Positive Negative
1 Make sure the cooling circuit valves are open.
2 Verifying the water circuit connections.
3
Check that all liquid supply pipes have manual shuto taps just outside the machine, and
that these taps are open.
4 Verify that the hydraulic circuits have been adequately cleaned.
5 Verify that there is no air in the hydraulic circuits.
6 Verify that there is water in the circuit and that the pressures are within the operating limits.
7
Verify that the water temperature entering the circuit is consistent with that indicated in the
project and is within the operating limits.
8
Verify any presence and concentration of glycol in the circuit and that it is consistent with
that indicated in the project.
15.1.5 CHECKS ON THE AIR CONDENSED DIRECT EXPANSION CIRCUIT
Description Positive Negative
1 Diagram of cooling circuit
2
Check that the supply and liquid pipe diameter fulls the indications in the installation
manual.
3
Check that the horizontal sections of the supply and liquid pipes have a gradient of at least
1% in the direction of refrigerant ow.
4
Make sure there are oil traps at the base of each rising pipe and every 5 m rising pipe sec-
tion (raised condenser).
5
Make sure the check valve is installed as near as possible to the compressor with the aper-
ture in the direction of refrigerant ow (raised condenser).
6
Make sure the check valve is installed as near as possible to the compressor with the aper-
ture in the direction of refrigerant ow (lowered condenser).
7
Check that the supply pipe is insulated in the sections where accidental operator contact is
possible (Pipe temperature in operation approx. 70/80 °C).
8
Check that support brackets are installed on the supply and liquid pipe are not too tight, so
as to allow expansion of the pipe.
9
Check that cooling circuit pipe connections of the condenser with the evaporator are oppo-
site the ow direction of the air ow.
10
Check that the condenser is positioned correctly, to prevent air recirculation that would
otherwise impair performance.
