Information regarding the refrigerant used in this appliance (R410A)
NOTE: Any work requiring access to the refrigerant circuit must only be carried out by a refrigerant
competent engineer.
R 410 A is a high-pressure refrigerant (+ 50% in relation to R 22 and R 407 C). Compressors approved
for operation with this fluid are filled beforehand with polyalcohol oil.
Contrary to mineral oil, it is very hygroscopic: it absorbs the humidity of the ambient air very quickly.
This can modify its lubricant properties and will lead to serious damage to the compressor. Refrigerant
material can be hazardous.
Contact Baxi Technical Enquiries 0844 871 1568 for further information.
Maintenance Instructions
1. Never add oil to the appliance; the compressor is filled with polyalcohol oil, a special oil which cannot
tolerate the presence of other oils.
2. Instruments used for the following:
- filling,
- pressure measurements,
- emptying under vacuum,
- recovering the fluid,
must be compatible with and only used for R410A fluid.
NOTE: the pressure taps of the refrigerating circuit are 5/16 SAE (112-20- UNF)
3. In the case of a new charge:
- the charge must be undertaken in liquid phase,
- use a balance and a dip pipe type R 410A cylinder,
