Description
Performing a proper system evacuation prior
to charging directly increases the expected life
and efficiency of the system. Fieldpiece vacuum
pumps provide a new view at system evacuation.
Good oil is the lifeblood of every evacuation.
You need to know the condition of the oil. You
need to change the oil easily with no mess.
Clearly view the oil condition through the huge
oil tank window.The oil backlight helps to see the
condition of the oil and if the fill level is correct.
With the RunQuick™ oil change system, you
can replace the oil in under 20 seconds without
losing vacuum, even while the pump is running.
The extra wide base helps prevent tipping and
spilling oil. Four inline ports in three different

Grounding Instructions
This product must be grounded. In the event of an electrical short
circuit, grounding reduces the risk of electric shock by providing an
escape wire for the electric current. This product is equipped with a
cord having a grounding wire with an appropriate grounding plug.
The plug must be plugged into an outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
WARNING – Improper installation of the grounding plug is able to
result in a risk of electric shock. When repair or replacement of the cord
or plug is required, do not connect the grounding wire to either flat
blade terminal.The wire with insulation having an outer surface that is
green with or without yellow stripes is the grounding wire.
Check with a qualified electrician or serviceman when the
grounding instructions are not completely understood, or when in
doubt as to whether the product is properly grounded. Do not modify
the plug provided; if it does not fit the outlet, have the proper outlet
installed by a qualified electrician.

Tech Tips
General
1. Vacuum pumps are not refrigerant recovery machines and should
not be used for recovering refrigerant.
2. Purge the A/C system with a few psi of dry nitrogen before
evacuation to pre-dry the system.This extra step actually saves
time overall because it quickly removes a great amount of
moisture, oil, and other contaminants before you even connect
your pump.
3. Performing a triple evacuation is a great way to ensure a system
is dry. The nitrogen flow can help carry moisture with it out of the
system. A triple evacuation is as follows:
1. Purge with nitrogen
2. Evacuate down to 2000 microns
3. Purge with nitrogen
4. Evacuate down to 1000 microns
5. Purge with nitrogen
6. Evacuate down to below 500 microns
Cold Weather Starts
1. Open an unused input port to ambient for a few seconds until the
pump is running.
2. Warm the pump in your truck/home by letting it sit in a warm
environment.You can warm the oil in your truck/home before
adding it to the pump.
Setup
1. Always use fresh Fieldpiece vacuum pump oil. If oil is left in the
pump for more than a week, the oil may have absorbed enough
moisture from ambient air to affect performance.
2. Refrigerant manifolds can be convenient to charge the system
after evacuation, but their hoses and valves can limit or slow
evacuation. It’s best to use vacuum rated hoses, directly
connected to core removal tools at the service ports.
3. If you want to use a manifold, it’s best to use a 4 port manifold. 4
port manifolds typically have a larger bore to increase flow. They
also isolate the pump from the system and micron gauge without
the need of a shut-off valve on the hose.
4. Hoses:
Short as possible.
Widest diameter as possible.
Vacuum rated.
Core depressors removed.
Ball valve shut-offs instead of low loss fittings.
Good seals.
Replace if worn.
5. Use a vacuum rated Schrader valve core removal tool to
temporarily remove valve cores from service ports.
6. Connect multiple hoses to the inline ports on VPX7/VP87/VP67 to
further decrease hose restriction and increase air flow.

RunQuick™ Oil Change System
The only way to create a deep vacuum is to
evacuate with fresh oil, especially at the end of
the job. The RunQuick oil change system makes
this old chore a breeze.
Easy View Window and Oil Backlight
There are a few signs that remind you to change your oil.The visual
condition is one of them. If it looks old, change it. You will see tiny air
bubbles with fresh oil. Saturated oil will look more opaque.
Elevated Oil Drain Ball Valve
By elevating the oil reservoir and utilizing a fast opening ball valve,
we made it easy to drain old oil into the empty bottle without a drop
spilled.
Oil Bottle Cap Storage
When you open a fresh bottle of oil, put the cap on the side of the
bottle so you can cap the bottle after you drain old oil into it.
Wide Mouth Fill Port
It is easy to hit your target with the wide mouth fill port.
Change Oil Quickly with the Pump Running
Towards the end of the evacuation is when you need fresh oil the
most.The RunQuick system maintains a vacuum for about 30 seconds
after you drain the oil so you can drain and pump without any loss of
vacuum.
Precision Oil Circulator and Fan
Instead of submerging the pump in excess oil, a small oil pump
constantly lubricates targeted sealing zones.The quiet high speed fan
cools the heat sinks of the motor and pump.
Spare Oil Bottle Storage
Take an extra bottle to and from the job site so you always have that
fresh oil performance bump at the end of the job.

Evacuation with a 4 Port Manifold
This is the most common evacuation method.
Read the tech tips (page12) for optimum gauge
placement and variations to reduce recovery
times.
1. Always fill with fresh Fieldpiece Vacuum Pump Oil (page 24).
Running the pump without oil will damage the pump and void the
warranty. Oil can be drained while the pump is running if refilled
within 3 minutes (within 30 seconds to maintain your vacuum).
2. Ensure the motor power switch is turned OFF (left).
3. Plug into a matching power outlet (oil backlight should illuminate).
4. Ensure the gas ballast is closed (vertical) (page 26).
5. Connect to the empty, depressurized A/C system.
6. Turn the motor power switch to ON (right).
7. Open line set (hoses, manifolds, removal tools, etc.) to expose the
pump to the system.
To reduce oil contamination early in the job, open the gas ballast until
the sound of the pump quiets down (about 3000 microns). The yellow
LED in the oil window shines if the ballast is open.
8. After the appropriate vacuum is reached, isolate the system from
the pump. You can check the system for potential leaks at this time
by monitoring your micron gauge.
Your vacuum pump has a unique oil suck back prevention feature
to keep your hoses clear of oil. Still, it’s good practice to release the
vacuum at the input port before turning off the pump.
9. Turn the motor power switch to OFF (left), remove your hoses, and
cap the ports to keep components free of contaminants.
10. Disconnect from the system and unplug from power at the outlet.
11. Drain the contaminated oil while the oil is still warm to keep the
pump as clean as possible when stored.

Oil Change Procedure
Changing oil is easy and visible. Start each job
with fresh oil. Change as needed during the job.
DRAINING OLD OIL
1. For extended pump life, drain the oil immediatly after the job
instead of waiting until the beginning of the next job.
2. Ensure the pump oil inside is warm enough, >75°F (>24°C), for
proper drainage. Run the pump for 10 minutes if ambient temp is
low.
3. Ensure the motor power switch is turned OFF (right).
Running the pump for longer than 3 minutes without oil will damage
the pump and void the warranty.
4. Plug into power to activate the oil backlight.
5. Ensure your old empty oil bottle is located under the oil drain.
6. Open the oil drain valve clockwise (vertical) to empty the oil
reservoir of old oil.
7. Close the valve counter clockwise (horizontal).
8. Remove and cap the old oil for disposal.
ADDING FRESH OIL
9. Ensure the drain valve is closed (horizontal).
10. Unscrew the pump’s oil fill cap 1/4 turn counter clockwise.
11. Open a new 8 ounce bottle of FieldpieceVacuum Pump Oil (OIL8X3).
Put the bottle cap on the side of the bottle (CAP STORAGE).
12. Pour the entire 8 ounce bottle of fresh oil into the oil port and
ensure the oil level is between the MIN and MAX lines indicated on
the window bezel. Replace oil fill cap.
13. Place the empty bottle under the drain valve so it’s ready to gather
used oil during the next oil change.
14. Your vacuum pump is now ready to operate.
Dynamic Vacuum Measurement
During the pull down, the system’s vacuum
level drops faster at the front of the system, near
the vacuum pump.
To ensure that your full system achieves the
target micron level, place the vacuum gauge
as far to the back of the system, away from the
pump, as possible.
Remote Exhaust
Unscrew the brass EXHAUST cap and connect
an obstruction-free garden hose if you need
to exhaust oil mist and vapor remotely to the
outside of a building structure.

2928
Gas Ballast Valve Switch
Much of the air and moisture in a system are
removed before reaching 3000 microns. For wet
systems, you should open the gas ballast during
this initial pull down. Doing so helps the pump
run smoothly and keeps the oil in good condition
for when you need it most -- towards the end of
the evacuation.
At about 3000 microns, when the sound of the
pump quiets down, the gas ballast should be
closed so that a deep vacuum can be generated.
Open
• Set here for initial pumping down
(above 3000 microns) of wet
systems.
• Yellow window LED shines.
• Discharge stroke exposed to
ambient.
Closed
• Normal operating position.
• Yellow window LED off.
• Discharge stroke isolated from
ambient.
LED Indicators
Three columns of LEDs in the oil window
indicate various states. The blue lights of the
right column indicate power is connected. The
blue lights of the middle column shine when the
pump is switched on.The LEDs of the left column
typically indicate the gas ballast valve is open.
Special Messages
Yellow Blink (Solid yellow LED on VP67):
Gas ballast valve open.
Yellow Blink + Red Blink (VPX7/VP87):
Low voltage detected.

Maintenance
General
Wipe with damp cloth to clean the exterior.
Do not use solvents.
Storage
Empty or replace oil at the end of every job.
Don’t leave old oil in the machine. Store the pump
and oil in dry clean areas for longest life.
Oil can lose its sealing properties if left
uncovered. Keep oil sealed until it’s ready for use.
Vacuum Isolation Test
Perform this test to ensure your vacuum pump
and your micron gauge are working properly.
1. Connect your vacuum gauge directly to a port on your pump.
2. Seal the 3 other ports.
3. Ensure the gas ballast is closed (page 26).
4. Switch your pump ON to create a vacuum at your gauge.
If your gauge measures below 200 microns within 1 minute, you
know your vacuum pump and micron gauge are working correctly.
If your gauge does not reach 200 microns, there is a problem with
your gauge, vacuum pump, or both.
Oil Window Cleaning
It’s important to see the condition of your oil
as well as the LED indicators located in the oil
reservoir.
The large oil drain ball valve will typically drain
solids and sludge when changing the oil. When
it becomes hard to see through the window, you
can remove the oil window for easy cleaning.
1. Ensure oil is drained from the reservoir.
To reduce residual oil spillage, do not lay the pump on its side.
2. While holding the black bezel (frame) in place, use a hex key (Allen
wrench) to remove the 4 hex socket screws.
3. While holding the glass oil window in place, remove the black bezel
and notice the o-ring located behind the window.
4. Slowly remove the glass oil window while making sure to locate
and remove the o-ring seal.
5. Wipe away any spilt oil, but leave a bit of oil on the o-ring to ensure
a good seal.
6. Clean the glass oil window and set aside to dry.
7. If desired, you can use a light bristle brush clean out the oil reservoir
itself, but performance is rarely affected by a dirty reservoir.
8. Place the o-ring back into its groove.
9. Place the glass oil window over o-ring and hold in place.
10. Reinstall the bezel over the glass oil window using the 4 hex socket
screws. To avoid breaking the window, start all 4 screws before hand-
tightening any of them. Do not overtighten.

Troubleshooting
Appropriate vacuum is never reached.
Ensure the gas ballast is closed (vertical position, yellow LED off).
Ensure oil is fresh.
Ensure oil level is between MIN and MAX lines.
Ensure all port caps are closed and have working seals.
Limit amount of connections. Check for leaks at connections.
Use vacuum rated hoses.
Check for blockages between the pump and the system.
Check for a system leak.
Verify your vacuum gauge is in the correct location and is accurate.
Use the right pump for the job, 6CFM up to 10CFM (over 50 tons).
Perform a triple evacuation to carry moisture out of the system by
purging the system with dry nitrogen.
Vacuum rises when isolating the system.
Ensure your micron gauge is located on the system side of the
shut-off valve.The micron gauge of a 3 port (2 valve) manifold cannot
measure a system’s vacuum if the valves are closed. Use a shut-off valve
at the third port to isolate the pump from the system (page 20).
Check for a system leak.
Oilbacklightdoesnotturnonwhenpluggedin.
Ensure power cord and outlet are functional and that source voltage
matches the pump. If backlight does not shine and the pump turns on,
the oil backlight LED module may need to be replaced.
Pump makes excessive noise.
The pump may be experiencing a high load.
Loose objects may be vibrating in the case.
Motor bearings may be bad. Motor needs to be replaced.
Motor may have come loose.Tighten motor mount bolts.
Oil level or condition may be bad. Change the oil.
Leaks may be present. Tighten or fix all connections.
Oil mist is coming out of the exhaust.
Some slight oil mist is normal due to airflow carrying oil as it passes
through, and out of the pump. You can attach a garden hose to the
exhaust port to control oil misting (page 25).
For larger systems with long evacuation times, extended high
pressure conditions can cause excessive misting to occur. Add oil as
needed if excessive oil loss occurs.
Motor does not start when switched ON.
Models VPX7/VP87 have a soft-start feature that slowly increases
speed during startup. Slow startup in cold temperatures is normal.
