Maximum Test Pressure: 31 bar pe (450 psig)
A cross-section of the CPCE regulator shows an internal spring-loaded mechanism. Inlet and outlet connections are depicted. The diagram indicates three connection sizes: 14 mm (9/16 in.), 22 mm (7/8 in.), and 32 mm (1 1/4 in.). The Danfoss part number A34N132.13 is associated with this diagram.
A diagram illustrates the brazing process for a pipe connection using 15% silver (Ag) solder. Heat is applied to the joint, and solder flows into the gap, indicated by melting solder and flux residue.
This diagram shows the tightening procedure for a fitting. It indicates a torque of 4 Nm, described as 'finger tight + 1/4 turn'. Rotational arrows show the direction of tightening. The Danfoss part number A34N147.13 is associated with this diagram.
A pressure gauge is depicted, calibrated in both bar and psig. The needle indicates a pressure of 0.4 bar (6 psig).
An adjustment mechanism is shown with rotational arrows and indicators for positive (+) and negative (-) adjustment. The adjustment range is specified as 360 degrees corresponding to approximately 1 bar (15 psi).
System Overview
A refrigeration system schematic is presented, showing the flow of refrigerant. Key components labeled include TE (Thermostatic Expansion Valve), LG (Liquid Gas Mixer), 69G (likely a filter/accumulator), KVP (shut-off valve), KVR (check valve/regulator), NRD (non-return device), and CPCE (Hot Gas Bypass Regulator). Arrows indicate the direction of refrigerant flow through the system, which includes a compressor (represented by a round tank) and a heat exchanger with a fan. The system also shows a manual shut-off valve labeled 'off'.
