R22 Retrofit Capability

Smiley face

The Daikin Premium Inverter can be retrofitted onto an existing R22 system by simply replacing both the indoor and outdoor units whilst retaining the field piping intact*.

This allows for a convenient and cost effective way of upgrading an existing system that may be towards the end of its useful operating life.

The Daikin Premium Inverter Series is equipped with three unique technologies that enable its R22 retrofit capability.

These are
  1. Inclusion of acid neutralising agents to counteract any residual chlorine ions that may impact system reliability
  2. Reinforced Electronic Expansion Valve to strengthen its corrosion resistance qualities
  3. Re-designed accumulator to effectively capture any residue that may impact on compressor reliability

ASSESSING RETROFIT SUITABILITY

Prior to undertaking a changeover of an existing R22 system, the following considerations must be taken into account by the Daikin specialist dealer:*

  • Does the existing pipe size and wall thickness meet guidelines?
  • Check pipe lengths and the condition of the piping
  • Is the existing system operational? Can it operate in cooling mode?
  • Can the existing system perform a pump down operation?
  • Has the compressor experienced a prior failure?
  • Is the system contaminated?

Strict guidelines apply. Please speak to a Daikin representative for more information.
