Note: READY appears on the top right hand corner of the screen.
Press and hold down the or keys to program
the cylinders manufacturer‚s maximum fill weight plus the empty tank. This can be calculated as
follows: 80%WC+TW WC=Water Weight Capacity of Cylinder, TW=Empty tank weight
6) Press the GO key to open the solenoid valve. This allows the flow of refrigerant to a refrigerant
recovery unit.
RECOVERY
1) Place the Scale on a level, rigid surface.
2) Press POWER key to turn the unit ON,
it zeroes out any weight on platform.
3) Select the desired unit by pressing UNITS key.
4) Connect scale as shown in Figure 1. Do not place cylinder on
platform at this time.
5) Press the SET key and the display will show:
READY
READY
000 lbs
000 kg
00.00 oz “ OR
0000 g”.
7)
Now place the cylinder on the scale platform as shown in Figure 2.
Caution: It is very important
not to place the cylinder on the platform before this step. Failure to do so could lead to
overfilling a refrigerant cylinder.
Danger- the recovery cylinder used contains liquid refrigerant. Overfilling of the recovery tank
may cause a violent explosion resulting in severe injury or even death.
8)
Turn on the refrigerant recovery unit. Follow the recovery unit‚s instructions.
9)
If the recovery process finishes before the weight exceeds the programmed maximum tank weight,
push the SET key to return to stop the RECOVERY mode and return to the Weighing mode. Reweigh
the tank to confirm the total weight of the cylinder does not exceed the maximum allowable amount.
10) If during the recovery process the gross weight exceeds the programmed maximum tank weight, the
solenoid valve will close preventing the additional filling of the refrigerant cylinder. Exchange the
cylinder with an empty one and proceed back to STEP 4.
When CHARGE mode has been completed, remove the cylinder from the platform, press and hold the
POWER key for 1 second to turn the unit OFF.
OTHER FEATURES
Battery Low Indications:
-Scale Electronics Battery
The battery indicator is shown on the LCD as a battery shape with a 3 segment Power Level Bar Graph:
Note: If the unit shuts off on low battery, the unit will revert to Auto Shut Off feature.
-Solenoid Valve Battery
The CC800A has a separate 9 VDC battery for the solenoid valve. It is located in the lower battery
compartment. Please note that the LCD low battery indicator does not detect battery levels for this battery.
If the Solenoid Valve battery is low, the CC800A will briefly sound an alarm after pushing the GO key while
in the RECOVER or CHARGE mode. Under a low battery condition, the solenoid valve will only operate
with up to 350-PSI differential. A fresh valve battery will operate the solenoid valve with up to 485-PSI
pressure difference across its ports.
