NOTICE
When purging air with the manual air purge valve of the unit, collect any fluid that
might leak out of the valve. If this fluid is NOT collected, it might drip on internal
components and damage the unit.
INFORMATION
▪
To purge air, use all air purge valves present in the system. This includes the
automatic or manual air purge valve of the outdoor unit, as well as any field-
supplied valves.
▪
If the system contains an external backup heater kit, also use the air purge valve
of the backup heater.
▪
If the system contains valve kit EKMBHBP1, it is required to – during the air purge
– manually switch the position of the valve kit's 3‑way valve by turning its knob,
this to prevent air from remaining in the bypass. For more information, see
"9.2.4 External backup heater
