Page 3: Use / Range Of Application
The maximum discharge rate of YET-A1 pump is 200 ml/min, and 100 ml/min for YET-A2 model. The max discharge pressure are 7 bar for YET-A1 model, and 15 bar for YET-A2 model. In order to protect the auxiliary equipments, there consists a pressure release valve to control the pipe pressure remains a constant value during lubrication times. -

Page 7: Installation
2-4 Installation 2-4.1 Mounting of lubricator Mount the lubricator on the machine by fastening it with two screws at the suspension hole (Fig. 2) to the hole on the machine for fastening the screws must have a distance of 188~206 mm. The lubricator should be mounted in the height of 0.6~1.7 m above the ground level. -
Page 8: 2-4.3 Connection Of Oil Pipe
2-4.3 Connection of oil pipe Connect the oilpipe now (Fig. 4). The elbow joint for the oilpipe is located at the right side of the lubricator. Remove the thimble nut and carefully take out the thimb inside the elbow joint and connect the oilpipe together with the nut and the thimble. - Page 9 Connect the cable at the connection points for power and alarm now (Fig. 8). First, open the screw for the point of the earthing .Next, connect the ground cable and fix it by fastening the screws. Connect the cables for plus and minus accordingly at "POWER" According to this connection the lubricator will send out an acoustic and an optic signal when the oil level reaches a critical minimum.

Close the cover after having connected all cables. For protecting the cable not to be pulled out of the box and disconnected from the ports, fasten the gland again (Fig. 9). The lubricator can be connected with the power supply now. When connected properly, you will hear a “beep”-sound first which is send out by the alarm. -

2. To protect the electrical stability, once you have turn off the power, please wait for at least 20 seconds to restart the lubricator. 3. The elbow joints of YET-A1 and YET-A2 are special parts, never change them by yourself. The YET-A2 lubricator is reacted by pressure release model. Generally, it should be compacted with piston distributers to control the mount of oil discharged per cycle precisionly. -
