Panasonic are doing our part
We at Panasonic are also doing our part – recognising that all finances are
under pressure at the moment. Panasonic has developed a clean and cost
effective solution to enable this latest legislation to be introduced with as
minimum an effect on businesses and cash reserves as possible.
The Panasonic renewal system allows good quality existing R22 pipe work to
be re-used whilst installing new high efficiency R410A systems.
By bringing a simple solution to the problem Panasonic can renew all Split
Systems and PACi systems; and depending upon certain restrictions we don’t
even limit the manufacturer’s equipment we are replacing.
By installing a new high efficiency Panasonic R410A system you can benefit
from around 30% running cost saving compared to the R22 system.

R22 - The reduction of Chlorine critical for a cleaner future
Guidance on re-using of existing R22 piping for a new
R410A installation
R410A installation
1. Precaution
The existing R22 piping can be re-used for a R410A system installation if
the following conditions are met and the piping are finally verified to be:
· Dry (no moisture remained in the piping)
· Clean (no dust remained in the piping)
· Tight (no refrigerant leak at the joining and piping)
The existing R22 piping can be re-used for a R410A system installation if

· Dry (no moisture remained in the piping)
· Clean (no dust remained in the piping)
· Tight (no refrigerant leak at the joining and piping)
2. Conditions
· Recover the refrigerant and oil.
· Recover the refrigerant and oil.
Operate “force cooling” according to the recommended operation time,
regardless of the piping length.
Single split: 10min.
Multi split: 30min.
After that, carry out “pump down” to recover the refrigerant and oil from
the existing R22 system
regardless of the piping length.
Single split: 10min.
Multi split: 30min.
After that, carry out “pump down” to recover the refrigerant and oil from
the existing R22 system
* Note: If pump down operation is not possible due to the malfunction of the system, flush and wash the existing piping to collect
back the oil and dirt inside the system.
back the oil and dirt inside the system.
· Check the oil condition.
If the oil contains dirt, wash the existing pipes
· Check the oil color.
After pump down, use a cotton bud to wipe the oil from the existing pipe.
If the oil color is higher than ASTM3, use a new pipe as re-use of old
piping is not allowed
If the oil color is higher than ASTM3, use a new pipe as re-use of old
piping is not allowed
Deterioration Criteria for Refrigerant Oil
· Check pipe thickness.
Make sure that the pipe thickness is more than 0,8mm.
If the thickness is less than 0,8mm, use a new pipe
· Rework the flare for R410A connection.
· Rework the flare for R410A connection.
Do not reuse the old flare nuts.
Make sure to use the new flare nuts attached to the R410a system
*Note: If the existing piping size is 1/4” (6.35mm) and 1/2” (12.7mm), and the new R410a system is 1/4” and 3/8” (9.52mm), use a
pipe reducer connected at indoor and outdoor unit.
