Pioneer KWIK-E-VAC is an all-new, revolutionary, patented kit designed to simplify the installation process. This product is intended to provide an alternative to a vacuum pump, a tool that was previously required to install mini splits. KWIK-E-VAC works by flushing the air and other non-condensable gases out of the copper line set and indoor unit combination, in order to ensure that the refrigerant in the system remains contaminant-free. In order to bleed the lines of any air and check for leaks, a vacuum pump and pressure gauges were previously needed. This kit allows the user to bypass that step, making any mini-split system truly DIY. Use this as an alternative for the inefficient and expensive quick-connect line sets, which reduce system efficiency and capacity, and cost 10 times more than the cost of this kit. A cost-effective, simple, and quick evacuation, perfect for most people and installations. Directions of use: This kit provides an alternative way to install a split air conditioner, if a proper vacuum pump is not available for the evacuation of the line sets. See below instructions, only to replace the specific section in the installation manual covering the use of a vacuum pump for evacuation. Follow all remaining instructions in the manual as originally written. Read all safety instructions above and wear protective gear as suggested. Keep the metal can upright at all times while using. Do not tilt or tip. Ensure the electrical power to entire equipment is switched off at the main breaker. Indoor section of the air conditioner: Connect both copper pipes of the line set to the indoor unit properly and as instructed in the equipment installation manual, using proper torque, methods, and materials approved by the equipment manufacturer. Outdoor section of the air conditioner: Connect ONLY THE GAS SIDE copper pipe (one with larger diameter) to the GAS side service valve of the outdoor unit properly and as instructed in the equipment installation m
