AK M80/86 Manual P/N 00-15000010 Rev 3 1. DESCRIPTION This installation and operation manual covers the series AK M80/86 crossover manifold. The AK M80/86 crossover manifold is used to maintain a continuous supply of source gas when the “in use” gas cylinder is depleted by automatically drawing gas from a standby cylinder. The AK M80/86 consists of a crossover regulator and a line regulator mounted to a common panel.
AK M80/86 Manual P/N 00-15000010 Rev 3 2. SAFETY The user is strongly recommended to carefully read this section covering general safety information and to adhere to specific safety information located throughout this manual. 2.1. General Safety Information All technicians that install, operate, or maintain this equipment should be trained in the use and hazards of compressed gases. Technicians should also be familiar with the hazards associated with the particular gas being delivered.
AK M80/86 Manual P/N 00-15000010 Rev 3 3. TECHNICAL SPECIFICATIONS 3.1. AK M80/86 Specifications 3.1.1. Physical Dimensions are approximately 6 inch wide by 10 inch high by 8-1/2 inch deep Weight is approximately 9 lbs. Mounting is by 4 each 1/4 inch diameter screws 3.1.2.
AK M80/86 Manual P/N 00-15000010 Rev 3 4. INSTALLATION This section describes how to install the equipment at a user facility. 4.1. General Use Teflon® pipe thread tape on NPT connections. When mating a 316 stainless steel pipe fitting to a 316 stainless steel AK M80/86 body, it is recommended that Teflon tape be applied to the first NPT thread to prevent galling upon assembly.

Connect Gas Lines to AK M80/86 Position a gas cylinder on each side of the AK M80/86 panel. Secure cylinders in place using an appropriate restraint system. Equipment can be supplied with various types of fittings and connections. The standard connections are 1/4 inch female NPT. Inspect the system to determine if the connection is NPT, tube compression, or other.
AK M80/86 Manual P/N 00-15000010 Rev 3 Install a check valve into port labeled “HP-B” on AK M80/86 manifold. Flow arrow on check valve should be pointing into the AK M80/86 manifold inlet port. Install manual shut off valve onto check valve. Connect a “pigtail” (bent piece of tubing with loops for flexibility and to reduce stress on connections) or flexible braided hose from the outlet of the left cylinder valve to the manual valve on the AK M80/86 manifold regulator inlet port labeled “HP-A”.

General Principle of Operation The knob for the crossover regulator has an “IN SERVICE” label with an arrow.
AK M80/86 Manual P/N 00-15000010 Rev 3 The line regulator is used to maintain a constant delivery pressure since the outlet pressure from the upstream crossover regulator fluctuates as A Side and B Side cylinders empty and are replaced. The line regulator is fully adjustable to the maximum outlet pressure. Rotating the knob clockwise increases the line regulator outlet pressure. 5.1.2. Initial Pressurization Confirm that an initial leak test has been performed and all leaks repaired.
AK M80/86 Manual P/N 00-15000010 Rev 3 5.1.4. Cylinder “A” Depleted Confirm that A Side (left) side cylinder is depleted by reading the pressure gauge. The exact pressure will depend on the specific AK M80/86 model. The approximate pressure when the A Side cylinder is depleted is given in Table 4. Rotate AK M80/86 crossover manifold “selection” knob clockwise until internal stop is contacted. The knob will rotate approximately 270 degrees.

Please contact the factory for assistance with other problem conditions or to discuss a specific problem in more detail. 6.1. External leak Possible causes: Connection not assembled properly with Teflon tape. Connection not tightened properly. Correction: Inspect equipment to determine source of the leak.
AK M80/86 Manual 6.4. P/N 00-15000010 Rev 3 Low delivery line outlet pressure Possible causes: Flow restriction. High flow at point of use Regulator knob adjusted incorrectly. Correction: Shut off the supply to the point of use and see if the line outlet pressure returns to normal setting. If outlet pressure returns to normal, then high flow or a flow restriction is the likely cause. Check the flow requirement at the point of use.
