3.1
From the valve, connect the yellow refrigerant hose to the middle port
of the manifold and connect the low pressure side (blue) and high
pressure side (red) of the manifold to the system.
Pay attention to the refrigerant flow direction. This is indicated by an
arrow on the valve.
3.2
When using the app, connect the valve directly to the system with
refrigerant hoses, without the manifold.
Ensure hoses are filled with refrigerant prior to opening valves into a
system to eliminate air from entering the system.
3.3
Click 3 times on on/off button to open the valve for 1 second and fill
the hoses with refrigerant.

Manual charging via weight
This function enables a refrigerant circuit to be charged manually via weight
using the
testo 560i
in combination with the app or
testo 550s / testo 557s
manifold.
By manually opening and closing the refrigerant bottle valve, the system is
charged with refrigerant until the target value (weight/superheating/subcooling)
is reached.
Displaying the current target values superheating/subcooling is only
possible in combination with
testo 115i
smart probes.
When using the manifold, the app is in second-screen mode. All
settings must be made on the manifold.
Before each measurement, check that the refrigerant hoses are in
flawless condition and applied to all ports tight to prevent leaks.
The system must be supervised by a competent person throughout the
entire process.
✓
testo 560i is connected via Bluetooth to the testo Smart App or the
testo 550s / testo 557s manifold.
✓
testo 560i is integrated into the refrigerant circuit.
