Diagnostic tests
The following diagnostics tests can be performed:
What it tests
Full test wizard
Full functionality test of the chiller.
1
Primary pump / bypass
valve
The primary cooling circuit is tested twice, once while the bypass valve is closed and again once
opened.
Secondary pump / valve
The functionality of the secondary circuit is tested, if available.
Pressure pump
The pressure pump is given a few short bursts. Open the tank cap slightly to see if cooling liquid
fl
ows through properly.
In order to open the tank cap, the same procedure can be used as when adding coolant to the tank.
For more info, see "Adding coolant to the tank", page 31.
