11.1 PUMPING REFRIGERANT BACK INTO THE EXTERNAL
UNIT
GENERAL NOTES
In this system, only R410A refrigerant is used.
▶ Only qualified and authorised refrigeration engineers may work on to
the refrigerant system.
▶ During installation work, use the tools and components specifically
designed for handling R410A refrigerant.
▶ Ensure the tightness of the refrigerant system. Escaping refrigerant
coming into contact with a naked flame will produce poisonous gases.
▶ Never release refrigerant to the atmosphere.
PREPARING THE HYBRID MANAGER
The refrigerant must be pumped back into the refrigerant collector in the
external unit, when working on the refrigerant circuit and also when
replacing the external unit or the hybrid manager.
▶ Ensure there are no current or pending heat demands and the system
has been idle for at least 5 minuets.
▶ Disconnect the power supply of the external unit (circuit breaker) and
the hybrid manager (switch off).
▶ Undo screws at the top and bottom of the appliance.
▶ Remove casing.
▶ Undo fixing screw on the left [1] of the hybrid control module.
▶ Push out the spring plate [2] and tilt the hybrid control module
forward.

[2] Spring plate
▶ Undo two screws and remove the small cover for the internal
connections at the back.
Fig. 68 Removing the small cover
▶ Undo two screws and remove the larger cover at the back.
Fig. 69 Removing the cover
▶ The DIP switches are now accessible.
▶ Put DIP switches in “Pump back refrigerant” position.
Fig. 70 DIP switches in “Pump back refrigerant” position
DANGER: Risk to life due to escaping refrigerant!
Escaping refrigerant can result in asphyxiation and frost
bite in the case of contact at its exit point.
▶ When refrigerant escapes, never touch any
components of the air to water heat pump and ensure
adequate fresh air ventilation.
▶ Avoid skin or eye contact with refrigerant.
▶ Seek medical attention if you get refrigerant on your
skin or in your eyes.
NOTICE: Damage from wet conditions!
Ingress of rain, humidity or dust can damage the PCB
inside the external unit.
▶ Never work on the external unit when it is raining.
▶ Following work on the terminal strip check that the
service cover sits firmly.
