Indledning
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.
Vigtige sikkerhedsoplysninger
Always observe basic safety precautions when using this product to reduce the risk of personal injury and damage to equipment.
- Læs alle instruktioner før brug.
- Brug passende personlige værnemidler (PPE), herunder sikkerhedsbriller og handsker.
- Sørg for, at arbejdsområdet er godt ventileret.
- Brug ikke pumpen i våde forhold, og udsæt den ikke for regn.
- Afbryd strømmen, før du udfører vedligeholdelse eller service.
- Use only with specified refrigerants (R134A, R12, R22).
Opsætning
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.
- Sæt oliepåfyldningsdækslet ordentligt på.
Connecting to an HVAC System
The pump features dual ports for R134A and R12/R22 systems. Use appropriate manifold gauges and hoses for connection.

Figur 1: 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.
- Kontroller, at alle forbindelser er tætte for at forhindre lækager.
Betjeningsvejledning
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.
Opretholdelse
Regular maintenance ensures the longevity and optimal performance of your vacuum pump.
Olieskift
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.
- Placer en passende beholder under olieaftapningsproppen.
- Fjern olieaftapningsproppen, og lad al gammel olie løbe helt ud.
- Replace the oil drain plug securely.
- Refill with new, clean vacuum pump oil as described in the "Initial Oil Fill/Check" section.
Generel rengøring
Keep the exterior of the pump clean and free of debris. Do not use harsh chemicals or solvents that could damage the housing.
Fejlfinding
Dette afsnit omhandler almindelige problemer, du kan støde på med din vakuumpumpe.
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Pumpen starter ikke | No power; Thermal overload tripped; Motor fault. | Check power connection and outlet; Allow pump to cool down; Consult qualified technician. |
| Pump not pulling sufficient vacuum | Low or contaminated oil; Leaks in system/hoses; Clogged inlet filter. | Change oil; Check all connections for leaks; Clean/replace inlet filter. |
| Overdreven støj/vibration | Low oil level; Damaged internal components. | Check and add oil; Contact customer support for service. |
