R22-Umrüstlösung
Possible to use on R22 pipings
An important drive to further reduce the potential damage to our ozone.
Why renewal?
It is often said that legislation is ruling our lives but sometimes it is there to help save lives. R22 phase out can be described as one of these and from Jan 1st 2010 the use of Virgin (new) R22 refrigerant was banned within the European Community.
Panasonic are doing our part
We at Panasonic are also doing our part – recognising that all finances are under pressure at the moment. Panasonic have 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.

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 VRF systems; and depending upon certain restrictions we don’t even limit the manufactures 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. The installation can also qualify for the government’s ECA (Enhanced Capital Allowance Scheme) which enables you to offset the cost against your Capital Gains Tax. Yes...

R22 - The reduction of Chlorine critical for a cleaner future
Panasonic’s Renewal system allows a completely new VRF system, indoor and outdoor units, to be installed using the existing systems pipe work. Panasonic’s advanced technology enables the system to work with previously installed pipe work by managing the working pressure within the system down to R22 (33 bar) levels, this ensures the system works safely and efficiently without loss of capacity.
The new equipment can offer increased COP/EER by using state of the art inverter compressor and heat exchanger technology. Having contacted your Panasonic supplier regarding pipe work restrictions and gained approval to use the Panasonic Renewal System there are three main tests that have to be carried out to ensure that the system can be used effectively.
Firstly a thorough inspection of the pipe work must be carried out and any damage must be repaired. Secondly an oil test has to be carried out to ensure that the system has not been subject to a compressor burnout during its lifetime, Lastly a VRF Renewal Kit (CZ-SLK2) has to be installed within the pipe work to ensure that the system is cleaned of any remnants of oil.

VRF Renewal Kit (CZ-SLK2) and Sight Glass
The following shows an overview of the VRF Renewal Kit (CZ-SLK2) that is required when existing tubing is reused. If the exact tube length and tube size of the existing tubing are uncertain, attach a sight glass in accordance with the figure below. It will be used for checking the amount of additional refrigerant charge.

Hinweis: Wenn der Leitungsdurchmesser nicht mit dem der vorhandenen Rohrleitung übereinstimmt, kann ein Reduzierstück (bauseits) verwendet werden.
Schauglas (bauseits)
Wenn Länge und Durchmesser der vorhandenen Leitungen nicht exakt bekannt sind, muss ein Schauglas in der Flüssigkeitsleitung installiert werden, mit dessen Hilfe überprüft werden kann, ob die zusätzliche Kältemittelmenge ausreichend ist.

Einbau von Filtertrockner-Kit und Schauglas
- Um das Druckniveau auf 33 bar zu begrenzen, müssen bauseits bestimmte Maßnahmen ergriffen werden.
- In die Flüssigkeitsleitungen aller Außengeräte müssen Filtertrockner eingebaut werden.
- In die Flüssigkeits- und Gasleitungen aller Außengeräte müssen Hochdruckschalter eingebaut werden.
- Filtertrockner-Kits brauchen nach dem Testbetrieb nicht entfernt zu werden, weil der normale Betrieb auch mit installierten Kits fortgesetzt werden kann.
- Beim Einbau der Filtertrockner-Kits ist auf die richtige Einbauposition sowie die korrekte Ausrichtung von Filtertrockner und Kugelventil zu achten. Bei falschem Einbau muss das Kältemittel aus dem System entfernt werden, wenn der Filtertrockner ausgetauscht wird, was die Wartung erschwert.
- Das Filtertrockner-Kit muss mit einer Wärmedämmung (bauseits, hitzebeständig bis 80 °C oder höher und mit einer Dicke von min. 10 mm) versehen werden.
- Der Filtertrockner des Filtertrockner-Kits muss in Abhängigkeit vom Zustand des vorhandenen Geräts möglicherweise ausgetauscht werden. Verwenden Sie Danfoss DMB 164 (bauseits) als Austauschteil für den Filtertrockner.
