Make the connections to the utility panel
Required tools, materials, and parts
13/16-inch wrench
1-1/2-inch wrench
5/8-inch wrench
1/4-inch NPT male connector
Two 3/4-inch NPT male connectors
Two -16 JIC female connectors (for an air-cooled pump)
Two 1-inch NPT male connectors (for a water-cooled pump)
1. Remove the caps and the covers from the fittings on the utility panel.
2. Connect the air and water lines.
CAUTION
Do not couple the WASTEWATER OUT and the COOLING OUT lines. Coupling these lines can cause
cooling water to back up into the system, which can cause damage to the bleed-down valve and the
intensifier parts.
WASTEWATER
OUT
3/4-in. NPT male
connector
This line carries water from the bleed-down valve and the
low-pressure system to the drain.

Install the wastewater plumbing so that it is lower than the fitting on
the pump to prevent contaminated water from entering the
bleed-down valve.
COOLING IN
Water-cooled pump
1-in. NPT male
connector
Connect this line to the water supply or to the chiller supply.

Public utility water is usually sufficient. If the public utility water has
a high mineral content, prefiltering or softening might be necessary
to prevent deposits from clogging the plates or tubes in the heat
exchanger.
Air-cooled pump
-16 JIC female
connector
Connect this line to the top fitting on the external heat exchanger.
CUTTING WATER
IN
3/4-in. NPT male
connector
Connect this line to the cutting water supply.

Treat low-pressure cutting water with a water softener or a reverse
osmosis system.
COOLING OUT
Water-cooled pump
1-in. NPT male
connector
Connect this line to the drain or to the chiller return.
Air-cooled pump
-16 JIC female
connector
Connect this line to the bottom fitting on the external heat exchanger.

The connection on the heat exchanger is usually marked INLET.
