厂家原指令： Directions for Use: 1. Properly identify the low side and high side service ports, and make sure system is running. If unit is a heat pump, then set it in cooling mode. Injector features an adjustable valve core depressor. If valve core on the system’s low side service port is set too deep to depress, turn valve core depressor counterclockwise up to 1.5 turns to engage system valve core for installation. Connect EasySeal Ultimate’s female fitting to the suction service port of system. The one-way check valve will prevent refrigerant back flow. 2. Make sure to close both valves on manifold gauge set. Connect high side (red) line of manifold gauge set to the high side service port. Barely thread the middle manifold hose (yellow) to the male fitting of the injector. Do not thread to the point of depressing the Schrader core. Briefly crack open high side manifold valve to purge air out of the yellow hose. Then close high side manifold valve, and quickly tighten yellow hose fitting to the injector. 3.Briefly open and then close high side valve of the manifold gauge set to allow a little high side liquid to flow through the yellow hose and EasySeal Ultimate tube. With high side valve of the manifold gauge set closed, wait one minute for the yellow hose and EasySeal Ultimate to equalize to suction pressure. Disconnect the injector from suction service port and from manifold gauge set. Discard or recycle empty injector.
