Use the 2 way heavy duty manifold for hakko air pumps hk 25l through hk 80l. Aluminum 4 way manifold.
How To Zero A Pressure Transmitter Three And Five Valve
4 way manifold diagram. This provides a way to monitor the health of an air conditioning system. A supply of r 134a refrigerant if needed for recharging available locally open ended wrench set. Transmitter drainvent isolate. Often attached to differential pressure gauges to measure liquid level in tanks these manifolds have two isolation valves with a pressure equalizing valve between them. If unsure consult the system flow diagram. Not all 4 way valves use the spool type designhowever the spool valve enjoys the advantage of having pressure balance on its one moving part.
An air conditioning manifold gauge set is a must have tool for anyone who is interested in performing some basic system work at home such as checking pressure in ac lines determining if theres a leak adding small amounts of refrigerant. Two isolate valves provide instrument isolation and one equalize valve is positioned between the high and low process connections. 38 vacuum port for use with larger hose to cut evacuation time by up to 33 all other fittings are 14 large easy to read 3 18 90 mm steel case red and blue 1 accuracy class 1 gauges. 4 5 7 6 9 3 2 tm 2006 jb industries inc. An air conditioning manifold gauge set. 03 02 2011 0908 pm 8 tech rob.
The outlets on the manifold are 38 barb. Due to its sensitivity the gauge may need to be zeroed in prior to usage. If you examine these cut away illustrations closely you will see that the two lands present equal surface areas to the two pressures pump and tank p and t in perfect vertical symmetry such that any forces acting on the two lands from. Connect the high side service hose red to the discharge high side of the ac system. 2 i never trusted 4 way for evacuation. The brass manifold connects to your pump via a 34 barb.
To isolate your differential pressure gauge for maintenance or calibration shut off flow on both sides and equalize pressure in the manifold. A look at the 4 way ac manifold gauge set from orionmotortech omt. The hakko air pump outlet fitting comes with a white l tube that will connect directly to the 2 way manifold. Adjusting gauge recal to zero 1. Charging and testing 4 valve manifold limited warranty instructions parts list with free floating double o ring piston seal each gauge is individually tested and calibrated prior to shipment. This set while fairly complete is missing a r134a.
The three valve configuration is available on rosemount 305 and 304 manifolds for use with differential pressure and multi variable transmitters. Get yourself a ritchie vacuum manifold to hook onto the pump with 38 hoses and the valve connectors to remove the schreader cores. Start the car operate the ac on max and monitor the high and low side pressures. Use with water oil air and inert gas. They are rated for at least 6 000 psi. Connect the low side service hose blue to the suction low side of the ac system.
