⌦WARNING: 1. This equipment operates at high pressures and at high voltages and if improperly used may cause personal injury. 2. Must be operated by qualified and certified personnel. 3. Read instructions carefully before operating or servicing. 4. To prevent personal injury from refrigerants operators must wear safety glasses, gloves and protective clothing. 5. Do not operate equipment if damaged. 6. Safety devices require the use of authorized refillable tanks. 7.
Your SKYE EP9N is designed for vapor and liquid Refrigerant RECOVERY, RECYCLING, VACUUM and RECHARGE of systems containing R134a ONLY. The ventilation fans run when the unit is connected to power. DO NOT LAY THE UNIT DOWN - THIS MAY CAUSE LIQUID REFRIGERANT TO SETTLE IN THE COMPRESSOR. The EP9N unit comes complete with. 1 x 96" Red service hose with R134a HIGH SIDE service adapter. 1 x 96" Blue service hose with R134a LOW SIDE service adapter. 1 x Dual valve storage tank with float.
BEFORE OPERATING YOUR SKYE MACHINE FOR THE FIRST TIME, THE FOLLOWING PROCEDURES MUST BE CARRIED OUT. Your new unit and the storage tank must be evacuated (vacuumed) prior to use. Set Up Procedure: (REFER TO THE ILLUSTRATED LAYOUT ON PAGE 5.) 1. Open both the tank valves to vent the factory nitrogen charge (if any). 2.
⌦IMPORTANT: Before recovering refrigerant with your SKYE machine, the vehicle AC system must be off. OPERATING INSTRUCTIONS: 1. Close the high side and low side manifold valves and connect the (RED) high side and (BLUE) low side service hoses to the AC system. 2. Open the storage tank VAPOR port and connect the machine to power. 3. Turn the FUNCTION SELECTOR to RECOVER and press the RECOVER ON button.
1. With power connected and both service hoses connected to the AC system, turn the FUNCTION SELECTOR to the VACUUM position. 2. Turn the VACUUM PUMP SWITCH on. (NOTE: The vacuum pump will not start if there is pressure in the AC system or unit plumbing. If this occurs, recover the refrigerant in the system or unit plumbing and restart vacuum.) 3. Open the Low and High side manifold valves and evacuate the system for a minimum of 40 minutes. 4.
10. When the programmed amount of refrigerant has been dispensed, the solenoid valve will close and the scale will beep. Close the manifold valves. 11. If the refrigerant tank empties before the programmed charge is reached, press the GO/HOLD key again. The solenoid will close and the unit will beep approximately once per second; the scale will retain the current reading, indicating how much refrigerant has been charged.
NOTE: This machine features single pass recycling. It will clean most refrigerant as it is being recovered. This procedure may be used when refrigerant is extremely dirty or when a tank of recovered refrigerant is to be recycled. 1. Using the Liquid Charging/Utility Hose, connect the TANK LIQUID PORT to the LOW SIDE SERVICE HOSE PORT and the TANK VAPOR PORT to the VAPOR OUTLET PORT. 2. Open the storage tank VAPOR and LIQUID valves. Press the RECOVER ON button then open the blue manifold valve.

Connect the machine VAPOR OUTLET hose to the BLUE service hose port and open the BLUE manifold valve. 4.
6. Swing the vacuum pump platform into the original position and replace the locking pin then replace the cover panel. YOU ARE NOW READY TO BEGIN NORMAL SERVICE OPERATIONS NOTE: You may check the compressor oil level at any time using the following steps. 1. Purge the system as described in the Purge Procedure. 2. Remove the brass cap from the compressor oil port - Oil should drip rapidly from the port. If rapid oil drip is not present, tilt unit backwards until oil flows out of port.
