1) Turn both discharge and suction valves in the middle positions.
2) Connect the manifold high or low pressure hose to the discharge or suction
valve and connect it to a vacuum pump.
3) Open the manifold high and low pressure valves to evacuate the system.
4) Close the manifold high and low pressure valves and switch it to a charging
scale.
5) Open the manifold high and low pressure valves to charge the system using
the recommended initial charge.
6) Close the manifold high and low pressure valves. Turn on the power to start
the system.
7) Check the following temperatures and pressures.
8. Adjusting and Completing the Installation
1) Checking pressure control settings
I.
The
encapsulated pressure control (if applicable)
Suction pressure setting (fixed): Cut in = 32 psig; Cut out = 10 psig;
Fig. 12 Fixed Pressure Control
II.
The adjustable
pressure control (if applicable for pump-down)
Suction pressure setting: Cut out=5 psig; Cut in=25 psig; Differential=20 psig
Head pressure setting: Cut out=230 psig; Cut in=150 psig; Differential=80 psig
It is necessary to adjust the setting in the field to reach the correct cycle time.
