STARTUP & SAFE OPERATION 9 Do not use a damaged unit. Check for shipping damage and place a claim with carrier if damage is discovered. 9 The TC670RR should not be operated or serviced by any person who has not read all the contents of this manual. 9 This manual describes normal operation and maintenance for the TC670RR. 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.
RECOVER - RECYCLE To Recover - Recycle, refer to the above illustration and follow these steps: 1. Attach the Red and Blue Hoses to the A/C system per the manufacturer's instructions. 2. Open the High and Low Gauge Valves. 3. Open the Red and Blue Hose Valves. 4. Press the top (ON) of the rocker switch marked POWER. 5. Press the top (ON) of the rocker switch marked RECOVER-RECYCLE. The TC670RR will automatically recover and recycle refrigerant from the A/C System until a vacuum is sensed.
OIL DRAIN & AIR PURGE Oil and Non-condensable Gas (Air) are separated from the recovered refrigerant and MUST be removed following EACH recycling procedure as follows: 1. SLOWLY open the Oil Drain Valve (located on the side of the unit, see page 7) to drain any oil which may have been removed from the A/C System. A plastic cup is provided to collect the oil. 2. Close the Oil Drain Valve. 3. Determine the room temperature. 4.
VACUUM If the A/C System is "opened" for replacing components, it is important to draw a vacuum on the system before recharging with refrigerant. The following steps should be followed: To Vacuum the A/C System, refer to the above illustration and follow these steps: 1. Connect the Red and Blue Hoses to the High and Low sides of the A/C System. 2. Open the Low and High Gauge Valves. 3. Open the Red and Blue Hose Valves. 4. Press the top (ON) of the rocker switch marked POWER. 5.
SELF EVACUATION The TC670RR can be used for different refrigerant types. The unit needs to be cleared of one refrigerant before introducing another refrigerant. To clear (self evacuate) the TC670RR: 1. Close the hose valves on the blue and red hoses. 2. Open the High and Low Gauge Valves. 3. Press the top (ON) of the rocker switch marked POWER. 4. Press the top (ON) of the rocker switch marked RECOVER-RECYCLE. 5.
SCHEDULED MAINTENANCE & FILTER MAINTENANCE MONTHLY... Clean the Condenser to maintain high efficiency performance of the TC670RR. Disconnect power and remove the Compressor Compartment Cover and blow compressed air through the cooling fins of the Condenser to remove any debris. Do not bend the fins on the Condenser coil. Air flow will be restricted and cause damage to the TC670RR. Replace the Compressor Compartment Cover before applying power to the TC670RR. PERIODICALLY AS INDICATED ON HOUR METER...
