RHS 900
- If, however, vacuum rises above -0.8 bar the yellow lamp indicates
VACUUM FAULT (pos. 19) and no refrigerant is charged.
- If in any case refrigerant is to be charged, refrigerant charging can be started
by activating the CHARGING switch.
- Before the actual charging process starts, the display will be indicating
“ PRESS. RIZING” in 2 minutes, where pressure is build up.
NOTE:
If the charging cylinder needs to be drained or replenished, connect the high
pressure service coupling to an external refrigerant bottle, (use the delivered
adapter if necessary). Open the high pressure valve on the RHS unit and the
service coupling.
If the charging cylinder must be drained, select the CHARGING process, (make
sure the refrigerant bottle can hold the amount).
If the charging cylinder must be replenished, select the RECYCLING process.
Also open the QUICKCHARGE-valve (pos.13), and wait till the desired amount
has been filled into the cylinder. Opening the Quickcharge valve will speed up the
process,- but remember to close the valve again during normal Recycling process,
otherwise the refrigerant quality can not be guaranteed.
Charging of Leakdetector Dye
The RHS900 is equipped with a third conection (pos. 11), wich can be used for
charging leakdetector dye or another oiltype if needed:
- Connect the oilcharging bottle (pos.B) or the Tracer Kit (pos.C) to the
connection pos.11, and wait untill the Evakuation process has been
completed.
- When using the oilcharging bottle , follow the instruction on the bottle.
 When using the Tracer Kit, first connect a Tracer on the Kit. Then open the
valve, until the colored dye has disapeared from the Tracer. Then close the
valve again.
