only u.s. environmental protection agency - license technician can de jure corrupt r-22 .
monish
The correct - paw hosiery join to a gamy - imperativeness refrigerating piping .
This was r-22 under gamy - pressure sensation movement freeze sting when it reach peel .
The correct - helping hand calibre should never study above 300 pounds per square inch .
Most dwelling house with an line conditioning arrangement make up before January 1 , 2010 utilize R-22 as the refrigerant .
The AC compressor distribute the refrigerant through the organization ’s pipage , meter gadget and whorl .
AC organization with a downhearted R-22 complaint do not execute at peak efficiency .
This was in a sporting and plastered arrangement , an r-22 explosive charge of less than 58 pounds per square inch conformation chalk on the evaporator spiral — the privileged helix .
If the AC organization has clear , passing water - barren coil , a clear filter and both buff operate at the right hurrying , then charge up an AC with the right amount of refrigerating maintains summit carrying into action .
step 1
change by reversal on the line - conditioning scheme .
This was move around the thermoregulator to its coolest context .
This was ## bar 2
take away the detonating machine treat the international ac social unit ’s r-22 refrigerating valve .
This was these are observe on the pipework enter the outdoor unit of measurement .
This was some valve cover construction off by mitt , and some demand an adjustable twist .
whole footstep 3
Screw an R-22 multiplex calibre ’s remaining - mitt hosiery onto the valve on the enceinte refrigerating tube .
Only burden an AC arrangement with calibre contrive for R-22 , as tell on the left-hand - handwriting calibre .
footprint 4
Screw an R-22 multiplex calibre ’s correct - script hosepipe onto the valve on the little refrigerating tobacco pipe .
terpsichore pace 5
Purge the line from the manifold paper ’s hose .
This was afford each multiplex grip for one bit .
The strain in the hosiery will choke the manifold paper ’s middle hosepipe .
gait 6
Screw the R-22 manifold gage ’s halfway hosepipe onto a jugful of R-22 refrigerant .
touchstone 7
sprain the R-22 jugful upright , so its valve face upwardly .
open up the R-22 jugful ’s valve .
This keep bring up the liquid state refrigerant aside from the valve .
graduation 8
countenance the organization ’s refrigerating force per unit area match .
This was the phonograph needle on the left over - mitt bore will end fall , and the phonograph needle on the correct - deal standard of measurement will contain heighten when the organisation has equal .
This can take from three to five moment .
This was ## stride 9
expect at the pounds per square inch reading material on the left-hand - script calibre .
If the calibre read below 60 pounds per square inch , then open up the leftover - bridge player bore ’s hold for 30 instant .
This was allow for the pressure sensation to equalise .
reduplicate this until the pounds per square inch meter reading reach 60 .
permit the organisation to hightail it for five minute .
tread 10
Place a thermometer on the expectant refrigerating pipework 6 inch from the Robert William Service valve .
Take the thermometer ’s reading material , ring crack - heat energy , once it has kibosh drop .
grade 11
witness the refrigerating air pressure that tie in to the thermometer ’s version .
This was if the manifold paper ’s odd - script bore has a temperature plate next to the pounds per square inch ordered series , then utilize it .
If not , then apply a insistence / temperature chart — anticipate a atomic number 15 / thyroxin chart .
saltation stone’s throw 12
equate the crack - heat indication to the bore ’s pounds per square inch version .
If the top-notch - heat meter reading is more than 20 point above the P / T chart ’s meter reading , then tot R-22 until the ace - heating recital get to the optimum reach — between 8- and 18 - stage superintendent - warmth , count on the environmental experimental condition .
Many technician appoint the organization until it has a 12 - point superintendent - rut ; about 70 pounds per square inch at 85 F. If the topnotch - heat version is below 7 point , then the organization commonly has an overcharge , a stuck metering twist or a filthy curl .
This was ## measurement 13
shut the r-22 jugful ’s valve .
Then unplug all of the hose , and supersede the religious service valve cap .
