Introduction The 34700Z model is used on R-134a vehicles; the 17700Z model is used on R-12 vehicles. Both models are designed to be compatible with existing service equipment and standard service procedures. Both models are UL-listed, single-pass systems that meet SAE specifications for recycled refrigerant. Follow the SAE-J2210 recommended service procedure for the containment of R-134a; follow the SAE-J1991 recommended service procedure for the containment of R-12.
Introduction Keypad Functions START YES START / YES begins or resumes a function, or answers a query. STOP NO STOP / NO terminates or pauses a function, or answers a query. MENU MENU displays the selection menu. START YES UP or DOWN arrows are used for scrolling through menu items. STOP NO AUTOMATIC RECOVER RECOVER activates the recovery sequence. MENU VACUUM VACUUM activates the vacuum and automatic recycling sequence, followed by an option to activate a vacuum leak check.
Introduction Menu Functions 1. Press the MENU button on the keypad. 2. Press the UP or DOWN arrow key to scroll through the menu choices shown on the second line of the display : SELECT LANGUAGE VERSION X.XX CHANGE DEFAULTS CHANGE VACUUM PUMP OIL VACUUM OIL TIME CHANGE FILTER FILTER CAPACITY RECYCLE ONLY TANK REFILL SELECT UNITS IMPERIAL / METRIC 3. Press START / YES to make a choice from the menu. Press STOP / NO to pause during any process, and STOP / NO a second time to exit a process.
Setup The first time the unit is powered up, it will display the initial setup mode. 1. Connect the power cord to the back of the unit, and plug the other end into a correct voltage outlet. 2. Turn on the main power switch. Select a Language IMPORTANT : R-134a systems have special fittings (per SAE specifications) to avoid cross-contamination with R-12 systems. DO NOT adapt your unit for a different refrigerant — system failure will result.
Setup Fill the Internal Tank 1. Connect the service hoses to the unit, and press START / YES. See Figure 3. 2. Connect the fill hose to a full source tank. 3. Open the source tank valve. 4. Install the source tank on the unit, and secure the tank using the tank strap. Note: If using a refillable tank, install the tank upside down and connect the fill hose to the vapor valve. 5. Press START / YES, and the unit will automatically run a 5-minute vacuum to clear all internal air.
Operating Instructions Recover Refrigerant 1. Empty the oil drain bottle located on the right-hand side of the unit, if necessary, or make note of the current oil level. See Figure 4. 2. Connect the high- and low-side hoses to the vehicle A/C system. 3. Open the coupler valves on the hoses. Oil Drain Bottle 4. Press RECOVER. 5. When the system has recovered to a vacuum level of approximately 13 in. Hg, the compressor automatically shuts off.
Operating Instructions Evacuate the A/C System 1. Ensure service hoses are connected, and the coupler valves are OPEN. Operating Tips • 2. Press VACUUM. VACUUM OIL TIME XX:XX CHANGE OIL NOW? 3. Press START / YES to accept the default evacuation time of 15 minutes, or enter the desired vacuum time using the number keys, and press START / YES. The unit pulls a vacuum on the vehicle A/C system to remove any air and boil off any moisture that may be present in the system.
Operating Instructions Replenish A/C System Oil Oil may be replenished through the high side after the vacuum function, or with an oil inject tool after charging the vehicle. IMPORTANT : To prevent damage to equipment, charge only the amount of oil that was removed from the A/C system during the recovery process. If no oil was removed from the A/C system during recovery, DO NOT charge any oil into the A/C system. Empty the oil drain bottle before recovering an A/C system to prevent an inaccurate oil charge.
Operating Instructions Recharge the A/C System If an oil inject has already been performed, you may skip steps 1 and 2. 1. Press CHARGE. 2. Select START / YES, to perform an oil inject; select STOP / NO to skip the oil inject. Operating Tips After selecting the CHARGE function and entering a desired weight, if the weight entered will leave less than 3 lbs. (1.36 kg) of refrigerant in the internal tank after charge, the charge function will not start. The display reads INSUFFICIENT REFRIG.
Operating Instructions Equalize Hoses contd. 3. Place the vehicle gear selector in park or neutral, with the emergency brake ON. 4. Start the vehicle. Set the A/C system to its maximum setting. 5. Press START / YES. The unit internally connects the low- and high-side hoses, allowing the vehicle’s compressor to pull the refrigerant into the A/C system.
Operating Instructions – Automatic The automatic function allows a user to program an automatic recovery, vacuum, leak test, and / or charge sequence. The user may choose to skip any step in the automatic operation during the programming. A total automatic sequence may take an hour to complete. Note: Oil recovered during the recovery cycle can be injected by the user before the charge cycle, or can be manually injected into the vehicle after charge using a separate oil injection tool.
Operating Instructions – Automatic Automatic Function contd. Note : • If a high-side charge has been selected, before charging, the automatic sequence will pause and “beep” for 30 seconds to allow the user to inject oil, if desired. See Replenishing the A/C System Oil instructions in this manual. Operating Tips • If problems are encountered during the automatic sequence, the unit will “beep” three times, and the control panel readout will pinpoint the problem encountered.
Maintenance General Maintenance 1. On a regular basis, wipe off the unit using a clean cloth to remove grease and dirt. 2. Periodically check internal components for leaks; over time, fittings can loosen as the unit is moved. Open the door panel, and trace lines using a leak detector. Check connections on the back of the unit also. Tighten any loose fittings or connections you may find.
Maintenance Changing Vacuum Pump Oil Fill Port For maximum vacuum pump performance, change the vacuum pump oil after every 10 hours of operation. The unit will prompt the user to perform a vacuum pump oil change after 10 hours of operation. 1. Press MENU. 2. Use the arrow keys to select CHANGE VACUUM PUMP OIL, and press START / YES to begin. 3. Allow the vacuum pump to run until it automatically stops (about 2 minutes). 4. Remove the plastic plug on the oil fill port of the vacuum pump. 5.
Maintenance Filling the Internal Tank This menu item is used to transfer refrigerant from the source tank to the internal storage vessel (ISV). 1. Connect the fill hose to a full source tank. 2. Open the source tank valve. HighSide Hose 3. Install the source tank on the unit, and secure the source tank using the tank strap. Low-Side Hose Note: If using a refillable tank, install the tank upside down and connect the fill hose to the vapor valve. HIGH LOW 4.
