later on. Charged objects are only a problem if they are in the vicinity of
the electronics. Observe a safety clearance of at least one metre from
foam rubber, protective film and other packaging materials, and do not
wear clothing made of synthetic fibres (e.g. fleece pullovers) and similar,
when you start work.
An earthed wrist strap offers good ESD protection when working with
electronics. This wrist strap must be worn when opening the screened
metallic bag/packaging or prior to exposing a fitted PCB. The wrist strap
must be worn until the PCB has been placed inside its screened
packaging or has been connected inside the closed control device.
Replaced PCBs that are returned must be handled in this way.
8.5 Pump down the refrigerant
▶ Remove the side cover to access the valves (instructions to remove
side cover at Fig. 15).
▶ Ensure that the system is installed correctly and ready for operation.
▶ Connect the manifold gauge to the service valve of low pressure side
(larger diameter).
▶ Select “tt” >> “PD” option in the ODU HMI menu.
▶ After approximately 1 minute the message “Cls Liq” will show in the
HMI. Close the liquid service valve (smaller diameter) with a hex key.
▶ When the message “End” is visible in the HMI, immediately close the
gas service valve with a hex key.
