12.1 Coolant Refill - Installation

1. Coolant Tank Mount
2. Stand Alone Mount

The Coolant Refill option features include:

• Automatically monitors the machine coolant level.
• Mixes shop water supply with coolant concentrate at user controlled ratios.
• Adds correctly mixed coolant at a specified concentration as necessary.
• Saves time by keeping the machine operator in front of the machine producing parts and not behind the machine mixing coolant.

Install the COOLANT REFILL onto the handle of the coolant tank as shown.

Install the water hose [1] into the elbow fitting [2].

Connect the HOSE [B] to the water supply [1].

Make sure the screen filter [2] is installed in the hose fitting for the water supply.

 Note: The Cone Side Of The Screen Filter [2] Must Point Toward The Water Supply.

Order additional supply HOSES [B] (comes with fitting [E]) from www.HaasParts.com or from any hardware store - 3/8" appliance supply line.

Start the water supply. Check for leaks.

 Note: The water supply must have a pressure of 40-100 psi (2.8-6.9 bar) to correctly produce the desired coolant concentration.

Important: To prevent damage to the solenoid valve, make sure the screen filter is installed to clean the incoming water. Debris in the solenoid valve causes it to stay open. This causes inconsistent coolant mixing, and it could also overfill the coolant tank. Your water supply may require additional filtration. Add an aftermarket water filter [1] with a pressure regulator [2] if your water supply has high mineral content or other debris. The water filter and pressure regulator in the picture are not included.

Install the NIPPLE [C] into the outlet port [1] as shown.

 Note: Move the coolant pumps so that the hole on the tank cover is under the NIPPLE [C].

Install the Fittings: Install a 1/2" nozzle to create backpressure in the system. This is needed for thick concentrate coolants.

• 58-3048 FITG HOSE BARB1/2 NPT3/8M STR BRASS [2]
• 58-1842 HOSE 1/2 ID PU NYLON BRAIDED [3]

Put the ORINGS [N] over the SCREWS [L] as shown.

Put the COOLANT REFILL [A] onto the STAND [K] so the SCREWS [L] pass through the slots [1] as shown.

Install the WASHERS [O] and WING NUTS [M] to secure the COOLANT REFILL [A].

Connect the HOSE [P].

Install the parts listed as shown onto the COOLANT REFILL [A].

• HOSE BARB [Q] 1X
• HOSE [P] 1X
• CAP [S] 1X
• CLAMP [R] 1X

Install the COOLANT REFILL [1] near the coolant tank and coolant connector bracket.

Put the HOSE [3] in the coolant tank [2].

 Caution: The HOSE [3] must be above the tank coolant mixture.

Cut the HOSE [3] as necessary. Secure the hose.

Classic Haas Control:

Connect the ADAPTER CABLE [H] to the CABLE [G].

Connect the ADAPTER CABLE [H] to the P52 connector on the I/O PCB.

Route the cable to the coolant connector bracket.

 Note: The coolant connector bracket is always located near the coolant tank.

Find the location on the coolant connector bracket that has the label COOLANT REFILL [1]. Install the other end of the CABLE [G] at this location. 

 Note: Drill a hole on the coolant connector bracket if it does not have this location.

Next Generation Control:

• Mill: Connect the CABLE [G] to the P36 connector on the I/O PCB.
• EC-400: Connect the CABLE [G] to the P35 pigtail on the I/O PCB.
• Lathe: Use the ADAPTER CABLE [K] on CABLE [G] and plug it into P16 and P17 on the I/O PCB.

Route the cable to the coolant connector bracket.

 Note: The coolant connector bracket is always located near the coolant tank.

Find the location on the coolant connector bracket that has the label COOLANT REFILL [1]. Install the other end of the CABLE [G] to this location.

Connect the power cable [2] for the COOLANT REFILL [1] to the CABLE [3] in the coolant connector bracket..
