Holymus Pro 1/4 HP 3.5 CFM Single-Stage 5 Pa Rotary Vane Air Vacuum Pump and R134a AC Manifold Gauge Set Kit for HVAC R22 R410a Air Conditioning Refrigeration Recharging Tool, Oil Included : Automotive

Description

Vacuum Pump is designed to have high efficiency and low noise output; High quality copper motor provide long-term durability, saves energy; The oil sight level glass on the front of the compressor section can tell how much oil is in the chamber as well as it's condition. The vacuum pump features a simple Oil Fill Port for a clean pour and Oil Drain Plug positioned beneath the oil reservoir to quickly drain when needed. Built-in high volume cooling is used to cool down the electrical motor and it will blow ambient air over the casing to dissipate this. Vacuum pump come with Intelligent radiator, when something is stuck, it can protect pump safety prevent it burning out. Extra large and colored dials with fahrenheit degree unit is easy to read, gauge rated 500psi (red) and 350psi (blue) max pressure; Sight glass design will help you see the flowing liquid refrigerant, when charging the refrigerant; Precise movement with upgraded gauge shell, stands up to heavy use and accidental drops, all metal parts made from durable bass and aluminum materials Professional 3 way automotive air conditioning diagnostic manifold gauge set will compatible with R134A, R410A and R22 refrigerants; Multicolored Coupler help identify the high-pressure side (red), low-pressure side (blue) . The Coupler feature a leak-proof seal design, which is very flexible, durable and not easy to damage; Come with additional 2pcs free Adapters for R410a air conditioning systems. The fins on the casing increase the surface area of the casing which allows us to remove more unwanted heat. Die-cast Aluminum Alloy Casing enables the vacuum pump be light and durable at the same time. No-slip rubber foot provide stability during working process. Vacuum pumps are used extensively by air conditioning and refrigeration engineers to remove air and non-condensables, such as water, from a system. We need to remove these with a vacuum pump because they cause the refrigeration system to operate inefficiently and they can also corrode the internal parts. Steps of introduction how to make air conditioning system cooler better. STEP-1 Find the high and low ports on the system, Before we get started make sure both of these valves are closed. (The low side port is the a big hose, and the high side port is usually on a small hose.) STEP-2 Attach the gauge set. Pull up on the coupler and make sure it's locked into place, next your are going to start to slowly run the valve in keep an eye one the gauge and as soon as the gauge start to move means the hose is connected, it's the time to stop. STEP-3 Connect Vacuum Pump through the yellow charge hose in the middle. Open the Valve, Start the pump keep working about one and half an hour. Until the pressure reaches -30. STEP-4 Leak Test. Close the valve on the gauge, turn off the pump and observe after 45 minutes. If the pressure can remain -30 unchanged, the confidentiality is good. Step-5 Add Refrigerant through the charge hose. You want to add a little bit at a time if you add too much it can be just as bad as not having enough.
