Manual
Requirements
• Minimum of 25 psi continuous operating water pressure
• Maximum 500 SUS coolant concentrate viscosity
• USE DISCHARGE HOSE PROVIDED. Longer lengths will less-
en concentration or provide none at all.
• Use proper ttings for water input and output. Restriction of
either will reduce vacuum pressure. Required tting sizes are
noted below.
• Keep drum upright
Installation Instructions
1. Congure the standpipe to t your concentrate container
type. Universal mixers will need to be adjusted depending
upon the required standpipe length. Use both standpipes
and the coupler for tote applications. You may need to re-
move and reattach the check valve to the lower end of the
standpipe conguration.
2. Remove the bung cap from the concentrate container.
3. Insert the required length standpipe into the container and
screw bushing into the 2” female thread in drum. Tighten the set screw.
4. Unfasten the breather cap from the concentrate lid.
5. Connect the included shut-off valve to the mixer head.
6. Connect the water line to the shut-off valve using the proper sized tting (see chart below).
7. Attach the 40” discharge hose, provided. Longer lengths will lessen concentration output. If delivering mix
through a garden hose, for instance, a proportioning pump is required.
8. Open the water valve, and after emulsion is dispensed, check the proportion with a refractometer, then
adjust the dial as necessary. Once the dial setting has been determined, secure with the locknut located
below the dial.
• Dial settings are for reference only. Varying water pressure and uid viscosities will produce different
mixing ratios.
• Turning the dial clockwise (right) will bottom out the needle valve onto its seat in the mixer body, pre-
venting coolant concentrate from entering the mixing chamber. At this point, the number zero should be
in-line with the pointer.
• Turning the dial counter-clockwise (left) will open the inlet orice permitting increasing amounts of cool-
ant concentrate to enter the mixing chamber.
• Maximum ratio delivered with four full turns of the dial.

Troubleshooting
Low Concentrations or None at All
1. Check the discharge hose. If you are NOT using the hose we provided, make sure you are using NO
MORE than 40” of discharge hose, with a minumum UNINTERUPTED ID of 1/2” for 3 gpm models, and
3/4” for 10 gpm models. Make sure that the hose has no kinks or other obstructions. If delivering mix
through a garden hose, for instance, a proportioning pump is required.
2. Examine the check valve at the bottom of the standpipe. Debris can keep it open, allowing concentrate to
drain back into the drum. The check ball should be below the valve’s set screw.
3. Check the water pressure. Our equipment requires a minimum pressure of 25 psi. TEST: Using the mixer
with needle valve closed, ll a pail of known volume and time it. If you can ll a 1 gallon pail in 20 seconds
there is enough pressure for our 3 gpm unit. If you can ll a 1 gallon pail in 6 seconds there is enough
pressure for our 10 gpm unit.
4. The needle-valve (dial) is numbered as a guide only. It does not indicate proportions. Turning the dial
clockwise reduces coolant concentrate ratio.
5. Check the coolant concentrate level in the drum. You may be running out.
6. Check the viscosity of the coolant concentrate. Our equipment is designed for up to 500 SUS at 100° F.
(SUS=saybolt universal seconds). 500 SUS is about the same as SAE30 motor oil.
Water Draining into Concentrate Container
1. Shut water ball valve off (check valve on end of standpipe is not rated to hold uid under pressure).
2. Check water ball valve for cracks or damage.
3. If using a selenoid valve, install it on inlet before water supply (check valve on end of standpipe is not
rated to hold uid under pressure).
Concentrate Siphoning from Container
1. Remove discharge hose from output holding container or sump.
2. Verify concentrate container’s breather hole is open.
3. Verify that the check valve is free of debri.
