(5) Post Charging Operational Check
(see Figures 2, 3, and 5 - numbers in parentheses refer to Figure 3, numbers in brackets refer
to Figure 5)
(a) Ensure that the low pressure control valve (3) [1] and the high pressure control valve (10)
[2] are closed. Hook up the charging stand to the system as shown in Figures 4 and 5.
(b) With Robinair 34700 style stands equipped with quick disconnect couplings only, ensure
coupler valves are open.
CAUTION: ASCERTAIN THAT THE AREA AROUND THE AIRPLANE IS CLEAR AND
THAT A QUALIFIED PERSON IS AT THE CONTROLS OF THE AIRPLANE.
CAUTION: ENSURE THE AIRPLANE IS HEADED INTO THE WIND.
(c) Activate the system and operate the engine at 1,000 rpm for 2 minutes. Then operate the
engine at 2,000 rpm for 2 minutes.
(d) Check the sight gauge on the receiver-dehydrator during the engine operation at 1,000
and 2,000 rpm. Any indication of bubbles passing the sight gauge indicates that additional
refrigerant is required.
(e) If additional refrigerant is required, add it slowly through the refrigerant control valve (11)
(Kent Moore J23500 style stands only) and the low pressure control valve (3) [1] until the
sight glass remains free of bubbles. Regulate the flow of refrigerant with the low pressure
control valve. Do not allow the compound gauge (2) or the low side gauge [1] to exceed a
reading of 40 psi.
(f) With the engine operating of 1,000-1,500 rpm, the low and high side gauges should
indicate as shown in Chart 5.
(g) With the charge properly established, stop the engine and, with Robinair 34700 style
stands equipped with quick disconnect couplings only, close the coupler valves.
(h) Close the low pressure control valve (3) [1] and, with Kent Moore J23500 style stands
only, the refrigerant control valve (11).
(i) Remove the charging stand. Replace all protective caps and covers.
