안전 정보

WARNING: Always read and understand all instructions before operating this equipment. Failure to follow these instructions may result in property damage, serious injury, or death.

• Always wear appropriate Personal Protective Equipment (PPE), including safety glasses and gloves, when working with refrigerants.
• Refrigerants can cause frostbite upon contact with skin or eyes. In case of contact, flush with water and seek immediate medical attention.
• Work in a well-ventilated area to prevent the accumulation of refrigerant vapors.
• Never expose refrigerant cylinders to direct heat or open flames.
• Ensure all connections are tight before pressurizing the system to prevent leaks.
• Do not over-pressurize the system. Refer to equipment manufacturer specifications for correct pressure ranges.
• Only use this manifold gauge set with refrigerants it is designed for (R-410A). Using it with incompatible refrigerants can lead to equipment damage or safety hazards.
• If you are unsure about any procedure, consult a qualified HVAC professional.

제품 끝view

The Yellow Jacket Mechanical Manifold Gauge Set is a robust tool designed for accurate measurement of pressure in air conditioning and refrigeration systems. It features two large, easy-to-read gauges and a durable brass manifold body.

주요 구성 요소:

• 매니폴드 본체: Constructed from forged brass for durability, featuring two handwheels for controlling refrigerant flow.
• 고압 게이지(빨간색): Measures pressure from 0 to 800 psig, typically connected to the high-side service port.
• 저압 게이지(파란색): Measures pressure from 30 In. Hg (vacuum) to 350 psi, typically connected to the low-side service port.
• 서비스 포트: 1/4" connections for hoses.
• 호스: Color-coded (red, yellow, blue) for easy identification of high-side, low-side, and utility connections.
• Swivel Hook: For convenient hanging during use.

포장 풀기 및 초기 검사

• 포장에서 모든 구성 요소를 조심스럽게 제거합니다.
• Inspect the manifold, gauges, and hoses for any signs of damage. Do not use if any component is damaged.
• Ensure all valve stems are fully closed (turned clockwise) before connecting hoses.

Connecting Hoses to the Manifold

• 연결하다 빨간 호스 to the high-pressure port on the manifold (typically marked "HIGH" or red).
• 연결하다 파란색 호스 to the low-pressure port on the manifold (typically marked "LOW" or blue).
• 연결하다 노란색 호스 to the central service port on the manifold (this is the utility port for vacuum pump, refrigerant tank, or recovery unit).
• Ensure all hose connections are finger-tight, then use a wrench to tighten them an additional quarter turn to ensure a leak-free seal. Do not overtighten.

General Manifold Gauge Set Demonstration

작동 지침

This section outlines common procedures using the manifold gauge set. Always refer to the specific service manual for the HVAC system you are working on for exact pressure specifications and procedures.

Pressure Testing (Static Pressure)

• Ensure the HVAC system is off and all manifold valves are closed.
• Connect the blue hose to the low-side service port and the red hose to the high-side service port of the HVAC system.
• Slowly open the low-side (blue) and high-side (red) valves on the manifold.
• Read the static pressures on both gauges. Compare these readings to the manufacturer's specifications for the system.
• Close the manifold valves and disconnect the hoses.

Refrigerant Charging (Liquid or Vapor)

• Perform a vacuum on the system first (see "Vacuuming the System" below).
• Connect the blue hose to the low-side service port and the red hose to the high-side service port of the HVAC system.
• Connect the yellow hose to the refrigerant cylinder. Ensure the cylinder is upright for vapor charging or inverted for liquid charging, as per system requirements.
• Purge air from the yellow hose by slightly opening the manifold valve connected to the yellow hose for a brief moment, then closing it.
• Start the HVAC system in cooling mode.
• Slowly open the low-side (blue) manifold valve to allow refrigerant to enter the system. Monitor the low-side pressure gauge and the refrigerant weight (if using a scale).
• Charge small amounts at a time, allowing the system to stabilize between charges. Do not overcharge.
• Once the desired charge is reached, close the low-side manifold valve and the refrigerant cylinder valve.
• Quickly disconnect the blue hose from the low-side service port to minimize refrigerant loss.

Vacuuming the System

• Ensure the HVAC system is off and all manifold valves are closed.
• Connect the blue hose to the low-side service port and the red hose to the high-side service port of the HVAC system.
• 노란색 호스를 진공 펌프에 연결하세요.
• Open both the low-side (blue) and high-side (red) manifold valves.
• Start the vacuum pump. Monitor the low-pressure gauge; it should drop into a deep vacuum (below 0 psi, into the "In. Hg" range).
• Allow the pump to run until the desired vacuum level is achieved and held for a specified period (refer to system manufacturer guidelines).
• Close both manifold valves, then turn off the vacuum pump.
• Observe the low-pressure gauge for any rise in pressure, which would indicate a leak in the system.
• Once the vacuum is held, disconnect the yellow hose from the vacuum pump.

유지

청소

• After each use, wipe down the manifold and hoses with a clean, dry cloth to remove any refrigerant oil or debris.
• Periodically check hose gaskets and O-rings for wear or damage. Replace as needed to prevent leaks.

저장

• Store the manifold gauge set in a clean, dry place, preferably in its original case or a protective bag.
• Utilize the dummy ports on the manifold to store the ends of the hoses, protecting the seals from damage and preventing contaminants from entering the hoses.
• Keep the gauges in a position where they are not subjected to impact or excessive vibration.

구경 측정

• The gauges are factory calibrated. If you suspect inaccuracy, consult a qualified technician for recalibration or replacement.
