BEFORE USING THE TX200

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

DO NOT USE A DAMAGED UNIT.

Refer to the Maintenance Section of this manual and verify correct Compressor oil level.
If not, do not apply power to the unit. Call 800-468-2321 for instructions.

Complete and return the Warranty Card within 90 days to activate technical support service
and warranty coverage.

Warranty claims can not be honored unless this warranty card is on file within 90
days of purchase.

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 and laws 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, R134a 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, UL

listed, 3-wire grounded, #14 AWG extension cord of the shortest possible length.

! Connect the TX200 to a properly protected, grounded receptacle. Do not over load the

circuit.

! 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 to the LIQUID VALVE of the DOT
Cylinder. The Hose from the DOT Cylinder to the External Disposable Filter (EDF) must
be connected to the VAPOR 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.
