If you have all the follow conditions perform this procedure:

1. You install an auxiliary coolant filter (AF) system.
2. The machine has Through-Spindle Coolant (TCS) or High-Pressure Coolant (HPC) 300.
3. The machine was made before June, 2015.

• Mills receive a check-valve. This procedure tells you how to install the fittings for each of these conditions:
  • The standard pump body has a 90-degree outlet [1].
  • The standard pump base has an elbow fitting [2] at the outlet.
• Lathes do not receive a check valve. This procedure tells you how to install the fittings for each of these conditions:
  • The standard pump body has a 90-degree outlet [3].
  • The standard pump base has an elbow fitting [4] at the outlet.

If the pump has an elbow fitting at the outlet port, go to step 3.

If the pump body has a 90-degree outlet [1], remove the plug [2] from the outlet port.

Install the 1/4" elbow fitting [3].

If the machine is a lathe, go to Step 5.

If the machine is a mill, remove the hose adapter [4].

If the machine is a mill:

• Install the nipple [1].
• Install the check valve [2].

 Caution: Make sure that the arrow on the check valve points up.

• Install the hose adapter [3] removed in Step 1.

Go to Step 5.

If the pump has an elbow fitting [2] at the outlet port:

• Remove the hose adapter [1].
• Install the tee fitting [3] to the elbow fitting.
• Install the 1/4" elbow fitting [5] to the tee fitting

If the machine is a mill, perform Step 4.

If the machine is a lathe, install the hose adapter [4] to the tee fitting.

Go to Step 5.

If the machine is a mill:

• Install the nipple [1].
• Install the check valve [2].

 Caution: Make sure the arrow on the check valve points up.

• Install the hose adapter [3] removed in Step 3.

Perform this step for mills and lathes.

Find the 1/4" hose [1] from the auxiliary coolant filter. The illustration shows the two possible installations:

• the 1/4" elbow fitting [2] on a pump with a 90-degree outlet
• the 1/4" elbow fitting [3] on a pump with an elbow fitting at the outlet

Perform this step for mills and lathes.

Find the coolant hose [1] from the supply port for the standard coolant. Connect the hose to the pump. The illustration shows the two possible connections:

• the pump with a 90-degree outlet [2]
• the pump with an elbow fitting [3] at the outlet

 Caution: Do not apply thread sealant to the hose adapter. This makes the hose difficult to remove.
