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

sizes give you tidy hose routing and hose options.

Place the power cord on the handle for tangle

free storage. Carry the machine to and from the

job site easily and well protected.

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 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 valves.

6. Connect multiple hoses to the inline ports on VP55/VP85 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.The spring loaded platform securely holds the bottle in place.

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.

ChangeOilQuicklywith

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 (VP85)

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 theVP55/VP85 motor power switch is turned OFF (down).

3. Plug VP55/VP85 into an outlet (oil backlight should illuminate).

4. Ensure the gas ballast is closed (vertical) (page 26).

5. Connect VP55/VP85 to the empty, depressurized A/C system.

6. Turn the motor power switch to ON (up).

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 LED

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.

VP55/VP85 has a unique oil suck back prevention feature to keep your

hoses clean. 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 (down), remove your hoses,

and cap the ports to keep components free of contaminants.

10. Disconnect VP55/VP85 from the system and unplug from power.

11. Drain the contaminated oil while the oil is still warm to keep the

pump as clean as possible when stored.
