Extra Procedures Pumping down refrigerant Pump down will be carried out when an evaporator is replaced or when the unit is relocated in another area. 1 Remove the cap from the low pressure side. 5 Disconnect the pipes connected to the outdoor units. At this time, cover the valve of the outdoor units and the other pipes using a cap or vinyl plug to avoid foreign material entering. Note: Make sure you do not bend the connection pipes in the middle and store together with the cables.
Extra Procedures NOTE ŷ Do not apply excessive force to the stop valve and always use special instruments. Otherwise, the stopping box can be damaged and the back sheet can leaks. ŷ If the watertight sheet leaks, turn the axis back by half, tighten the stopping box, then check the leakage again. If there is no leakage any more, tighten the axis entirely. Closing the stop valve 1 Remove the cap. 2 Turn the stop valve clockwise by using a hexagonal wrench.

Appendix [Spanish-ES] 1 Las fugas de refrigerante contribuyen al cambio climático. Cuanto mayor sea el potencial de calentamiento global (GWP) de un refrigerante, más contribuirá a dicho calentamiento su vertido a la atmósfera. Este aparato contiene un líquido refrigerante con un GWP igual a [2088].
[Portuguese-PT] 1 A fuga de fluido refrigerante contribui para as alterações climáticas. Os fluidos refrigerantes com menor potencial de aquecimento global (PAG) contribuem menos para o aquecimento global do que os fluidos refrigerantes com maior PAG, em caso de fuga para a atmosfera. Este aparelho contém um fluido refrigerante com um PAG igual a [2088].
Appendix [Polish-PL] 1 Wycieki czynników chłodniczych przyczyniają się do zmiany klimatu. W przypadku przedostania się do atmosfery czynnik chłodniczy o niższym współczynniku ocieplenia globalnego (GWP) ma mniejszy wpływ na globalne ocieplenie niż czynnik o wyższym współczynniku GWP. Urządzenie zawiera płyn chłodniczy o współczynniku GWP wynoszącym [2088].
[Romanian-RO] 1 Scurgerea de agent frigorific contribuie la schimbările climatice. Dacă s-ar scurge în atmosferă, agenții frigorifici cu un potențial de încălzire globală (GWP) mai redus ar contribui într-un mod mai puțin semnificativ la încălzirea globală decât un agent frigorific cu un GWP mai ridicat. Acest aparat conține un fluid refrigerant cu un GWP egal cu [2088].
Appendix [Danish-DA] 1 Kølemiddeludslip medvirker til klimaforandringerne. Slipper kølemidlet ud i atmosfæren, bidrager det mindre til den globale opvarmning, hvis dets potentiale for global opvarmning (GWP) er lavt, end hvis det er højt. Dette apparat indeholder en kølevæske, hvis GWP-tal er [2088]. Det betyder, at lækkes 1 kg af dette kølemiddel til atmosfæren, så vil det gennem en periode på 100 år bidrage [2088] gange mere til den globale opvarmning end 1 kg CO2.

Šajā ierīcē atrodas dzesēšanas šķidrums, kura globālās sasilšanas potenciāls GSP ir [2088]. Tas nozīmē, ka, ja vidē nokļūst 1 kg šā dzesēšanas šķidruma, ietekme uz globālo sasilšanu 100 gadu laikā ir [2088] reizes lielāka nekā 1 kg CO2.
