Recovering Large Quantities Of Coolant - Immergas AUDAX PRO 5 Instruction And Recommendation Booklet

8.5 RECOVERING LARGE QUANTITIES
OF COOLANT.
Should recovering the coolant be difficult due to
the large amount in play:
1 Get an empty tank for R-410A, a scale and a
manometric unit.
2 As shown in the figure, connect the central
coupling of the manometric unit to the coolant
tank and the side couplings of the manifold
itself to the outdoor unit service valves (leaving
the tank valve and the low side service valve
closed and leaving the high side service valve
open).
3 Start the coolant transfer procedure by pressing
the K2 button three times.
4 After 10 minutes, open the tank valve to trans-
fer the coolant.
5 Close the tank valve as soon as the desired
quantity of coolant has been transferred.
6 Immediately close the liquid side service valve.
Also close the gas service valve as soon as the
low side pressure goes below 0.
7 Press the reset button to abandon the Stop
procedure.
