3.1
From the valve, connect the yellow refrigerant hose to the low
pressure side (blue) 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.
8.4 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 valve, the system is charged with
refrigerant until the target value (weight/superheating/subcooling) is reached.
When using the manifold, the app is in second-screen mode. All
settings must be made on the manifold.
Before each charge, make sure that the refrigerant hoses are in
flawless condition.
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.
