4 VALVE MANIFOLD
• Forged aluminium body – durable and lightweight
• ¼ turn control valves for fast operation and increased refrigerant flow (EL84372 & EL86372)
• Piston style valves to ensure perfect sealing (EL64372, EL66300, EL66372, EL74300,EL74400)
SAFETY INSTRUCTIONS
Read these instructions and become familiar with the specifications and operation of this JAVAC
manifold prior to use. The instructions will give you important information in regards to the operation
of the manifold.
PURPOSE AND USE:
These manifolds have been designed especially to measure pressure in refrigerant equipment.

THE MANIFOLD MUST NOT BE USED:
• for other than refrigeration applications in connection with refrigerants. The manifold is not suitable for other
liquid of gases the those indicated on the gauge.
• with pressure higher than the pressure scale indicated on the high pressure gauge with manifold.
• as a pressure regulator.
• with Ammonia (NH-3).
• for pressure testing with Oxygen Free Nitrogen (OFN).
SAFETY GOGGLES AND GLOVES MUST BE WORN AT ALL TIMES DURING THE USE OF THE MANIFOLD.

OPERATION INSTRUCTIONS
CONNECTING MANIFOLD TO A SYSTEM
• Close valves A, B,C & D
• Connect hose 1, 2, 3 & 4 as shown
• Run the system and observe the pressures, check system manual for correct diagnosis
Refrigerant recovery
• Open valves A, B & C
• Close valve D
• Connect hose 1 and 2 as shown
• Connect hose 3 to inlet of recovery unit
