BEFORE USING THE TX200

Check for any shipping damage. Place a claim with carrier if damage is discovered.

DO NOT USE A DAMAGED UNIT.

The TX200 should not be operated or serviced by any person who has not read all the contents of this manual.
Failure to read and comply with these instructions or any one of the limitations noted herein can result in serious
injury and/or property damage.

These general instructions deal with the normal operation and maintenance situations encountered with the
TX200. The instructions should not be interpreted to anticipate every possible contingency.

It is the responsibility of the owner/user to operate the TX200 in accordance with all specifications an d l a w s
which may apply.

The following pages contain rules for safe operation of the TX200. Taking precedence over any specified rule
listed herein, however, is the most important rule of all:

"USE COMMON SENSE"

A few minutes spent reading these instructions can make an operator aware of dangerous practices to avoid and
precautions to take for his own safety and the safety of others.

A regular schedule of inspection of the TX200 should be established and records maintained with special
attention given to Hoses and Compressor Oil Level.

SAFETY PRECAUTIONS

! Recover R12, R22, or R502 Refrigerant only.
! Wear safety glasses and protective gloves. Refrigerant has a very low boiling point and can cause

frostbite.

! Follow the TX200 operating procedures sequentially to avoid prematurely disconnecting hoses or

opening valves which may release refrigerant to the atmosphere.

! Do not expose the TX200 to moisture or operate in wet areas.
! Use the TX200 in locations with mechanical ventilation that provides at least four air changes per hour.
! Hoses used with the TX200 must have shutoff devices within 12 inches of the connection point to the

system being serviced to minimize the release of refrigerant when being disconnected.

! Disconnect power before performing any maintenance or service on the TX200.
! Avoid using an extension cord with the TX200. If necessary , use a good condition, 3-wire grounded, 2.5

mm2 extension cord of the shortest possible length.

! Connect the TX200 to a properly protected, grounded receptacle. Do not over load the circuit.
! Unplug Power Cord while connecting the OFP (Overfill Protection) Device to avoid bodily injury due

to electrical shock. Do not force plug into OFP Device. Look at pins in plug and align them with sockets
on OFP Device.

! DO NOT CONNECT THE TX200 DIRECTLY TO THE LIQUID SIDE OF ANY A/C SYSTEM.

ALWAYS CONNECT A CYLINDER BETWEEN THE A/C SYSTEM AND THE TX200.
FAILURE TO DO SO MAY CAUSE THE TX200 COMPRESSOR TO FAIL.

RECOVERY MODE

Figure 1 shows the recommended connection of the TX200 to an A/C System.

Figure 1 TX200 Connection For Recovery

CAUTION...

The hose from the A/C System must be connected t o the LI Q UI D VAL VE of the DOT Cylinder. The Hose
from the DOT Cylinder to the External Disposable Filter (EDF) must be connected to the VAP OR VALVE of
the DOT Cylinder. This prevents introduction of large quantities of liquid refrigerant, oil and acid into the
TX200 which could damage the Compressor.

Do not depend on the colors of the Valve Knobs to indicate Liquid or Vapor. Always check the embossed
printing on the knobs.

The ERC Cylinder must have an Overfill Protection (OFP) Device.

Disconnect Power Cord from power source while connecting the OFP (Overfill Protection) Device to avoid
bodily injury due to electrical shock.

Connect Yellow Cable from TX200 to OFP Device on ERC Cylinder.

Do not force plug into OFP Device. Look at pins in plug and align them with sockets on OFP Device.

Connect TX200 Powe r Cord to a properly protected, grounded receptacle. Avoid using an extension cord. If
necessary, use a good condition, 3-wire grounded, 2.5 mm2 extension cord of the shortest possible length.

The TX200 is now ready to recover refrigerant.

Figure 2 TX200 Control Panel

Press the top of the ON/OFF Switch. The switch will illuminate to indicate that power is on.

The COMPRESSOR ON Light will illuminate and the TX200 will begin recovering refrigerant.

The CYLINDER FULL Light will illuminate if the ERC Cylinder fills to capacity.

The TX200 will recover refrigerant until a vacuum is sensed. The Compressor will turn off and the Compressor­On Light will turn off.

!!!! DO NOT TURN THE TX200 OFF OR DISCONNECT HOSES !!!!

A small quantity of Liquid refrig erant will pr obably r emain in the A/C System. This liquid will vaporize (boil
up) and increase pressure in the system as components again warm to ambient temperature.

If pressure increases to a preset level, the TX200 will again start to recover refrigerant. The Compressor will
turn on and the Compressor-On Light will illuminate.
