change compressor!!

this coldroom compressor breakdown. so start the job.

change the service valve first.y?bc the previous low quality got corrusion,the flare nut cannot be use.


this is my first time blazing,thanks Foo Gee give me some advise :)

after that change the new compressor.n now,vacuum in progress! notice the top left, is a solenoid valve, i change that too,previous is a manual valve. but no work as pump down, just shut off if compress not run.

filling R22. estimate 5kg

the sightglass is clear! it full !

i change that high low control switch too.job done!.

ps. this compressor is MT32,bc is emergency case,i use back the same spec,no time to do research, it should use MT28.y? i refer the spec n found out the orifice n condenser is not large enough to handle this compressor(the liquid line very hot). the previous stupid technician think upgrade the compressor can upgrade the performance...damn..now it was not efficiency...

modify hp adapter for the ID pin.

since two years ago,hp notebook start using three pin adapter,
1.positive,2.ground or 0v,3.ID
what's the ID. the identity of the adapter.
this pin provide information to notebook the adapter is original or non-original.
the early stage the 3 pins notebook accept non-original adapter.
so this the way to modify a 19v adapter to create pin 3.

the old burned adapter.

buy a cheap adapter cut the pin, red is 19v.

use a 47k R.

solded on 19v. n use the old connector head.

but remember!! do not update to the newest firmware. bc newest firmware not accept non-original adapter..
