adding additional gas on mitsubishi r2 system

[colin1981]

I need to add 7kg of additional gas to a r2 system what is the best way to put it in ??? Should i open valves and run up first or put it straight into pipework ???

[stufus]

Vac it down and lob it into the pipe work.
Open valves slowly when charged .
Any other additional gas can be flashed into the suction line.
Cheers

cheers mate , im best running it in cooling arent i and throttling the liquid in slowly then to get rest of it in ??

normally you will get it all in=if the charge is calculated correctly but if not stick it in test cooling and throttle it into ur suction line

i am asuming the charge is correct because its been reclamied by someone and now ive been asked to a recharge the system now we have moved a fan coil , ive already put 10 kg back in but ran out of time to get final 6kg , was a bit unsure if running it short of 6kg would damage it

if i reclaim gas i use the reclaim rig to pump it back in,no loss then

u can open the valves and reclaim it all back into the system prior to running
