NOTE: The above typical installation is only for reference. It may be different from your actual system design.

WARNING: If this is a new installation, or if the oil in the lines is contaminated, flush the lines before you

install the control valve.

1. PRE-INSTALLATION PROCESS

WARNING: To reduce the risk of serious injury, the pressure release should be concerned. Please follow

the Pressure Relief Procedure in OPERATION INSTRUCTIONS section for the release process.

(1) Close the fluid shut-off valve 4 as shown in Fig. 1.

(2) Ground the hose and reel or console.

WARNING: To reduce the risk of static sparking, effectively ground all of this equipment.

 Control valve: Use proper grounding wire to connect it to the pump. Always keep the metal part of the

control valve connected with the grounding equipment.

 Pump: Follow the manufacturer's instruction to ground it.

 Air and fluid hoses: Make sure they are effectively grounded.

 Air compressor: Follow the manufacturer's instruction to ground it.

 Oil barrel: Use a barrel that meets the local standard and ground it properly. A metal barrel can be put

directly on a surface of an electrical conductor which is well grounded.

 Staying grounded during the working and oil release process: Make sure that the metal units are

effectively grounded before operating the control valve.

2. INSTALLATION PROCESS

WARNING: To reduce the risk of serious injury, the pressure relief should be done very carefully. Follow

the PRESSURE RELIEF PROCEDURE in OPERATION INSTRUCTIONS section.

WARNING: Make sure the whole system is clean before installing/replacing a new control valve. No

impurities or contaminant are allowed to enter the control valve.

Follow the following steps ① – ⑤ to clean the oil supplying system before a new control valve is installed.

(The system also needs cleaning when the oil in the system is polluted).

①. Close the fluid shut-off valve at each dispensing point in the system.

②. Make sure the main fluid outlet valve at the pump is closed, the air pressure to the pump motor is lowered,

and the air valve is open. Slowly open main fluid valve.

③. Place the hose end (with no control valve connected) into a container to drain waste oil. Secure the hose in

the container so it will not come out during draining.

. Slowly open the shut-off valve at the dispensing position. Drain out a sufficient amount of oil to ensure that
