Introduction
This manual provides essential information for the safe and efficient operation, maintenance, and troubleshooting of your Pittsburgh 2.5 CFM 1/6 HP One Stage Vacuum Pump. Please read this manual thoroughly before operating the pump and retain it for future reference.
The Pittsburgh 2.5 CFM 1/6 HP One Stage Vacuum Pump is designed for deeper vacuum draw, pulling vacuum down to 75 microns. Its precision-machined one-stage pump effectively removes moisture from air conditioning systems, preparing them for safe refrigerant addition. This pump is ideal for automotive air conditioning, HVAC work, and other applications requiring high vacuum pull from a compact unit.

Жайгашуу
Before initial operation, ensure the vacuum pump is placed on a stable, level surface. Check the oil level and fill if necessary with appropriate vacuum pump oil.
Initial Oil Fill/Check
- Locate the oil fill cap and sight glass on the pump.
- Unscrew the oil fill cap.
- Pour vacuum pump oil into the fill port until the oil level is visible in the sight glass, reaching the indicated fill line. Do not overfill.

Connecting to an HVAC System
The pump features dual ports for R134A and R12/R22 systems. Use appropriate manifold gauges and hoses for connection.
1-сүрөт: The Pittsburgh 2.5 CFM 1/6 HP One Stage Vacuum Pump connected to an HVAC system. The image shows the vacuum pump on a wooden deck, connected via yellow and blue hoses to a manifold gauge set. The manifold gauge set is then connected to an outdoor HVAC unit. This setup illustrates a typical vacuuming process for an air conditioning system.
- Ensure all valves on the manifold gauge set are closed.
- Connect the appropriate vacuum hose from the manifold gauge set to the vacuum pump's inlet port.
- Connect the manifold gauge set to the service ports of the HVAC system.

Иштөө нускамалары
Follow these steps for proper operation of the vacuum pump to evacuate an HVAC system.
- With the pump connected to the system and manifold gauges, open the manifold gauge valves to the system.
- Plug the vacuum pump into a grounded electrical outlet.
- Turn on the vacuum pump. The pump will begin to pull a vacuum on the system.
- Monitor the vacuum gauge on your manifold set. Allow the pump to run until the desired vacuum level (e.g., 75 microns or lower) is achieved and held steady for a specified period (e.g., 15-30 minutes) to ensure all moisture is removed.
- Once the desired vacuum is reached, close the manifold gauge valves to isolate the system from the pump.
- Turn off the vacuum pump and then disconnect it from the manifold gauges.
- Proceed with refrigerant charging as per HVAC system manufacturer's instructions.
Техникалык тейлөө
Үзгүлтүксүз техникалык тейлөө вакуум насосуңуздун узак мөөнөттүү иштешин жана оптималдуу иштешин камсыз кылат.
Май алмаштыруу
Vacuum pump oil should be changed frequently, especially after each use on a contaminated system or when the oil appears cloudy or discolored. Contaminated oil reduces the pump's ability to pull a deep vacuum.
- Ensure the pump is off and unplugged.
- Май төгүүчү тыгындын астына ылайыктуу идиш коюңуз.
- Май төгүүчү тыгынды алып салыңыз жана эски майдын толугу менен агып кетишине жол бериңиз.
- Replace the oil drain plug securely.
- Refill with new, clean vacuum pump oil as described in the "Initial Oil Fill/Check" section.
Жалпы тазалоо
Keep the exterior of the pump clean and free of debris. Do not use harsh chemicals or solvents that could damage the housing.
