3.
Refer to the table below for the fitting sizes required for the your unit.
Model#
Fitting Size
RC006, RC011, RC022 3/8" FNPT
RC030, RC045
1/2" FNPT
Note:
Fittings should either be brass, stainless steel or plastic. Never use steel or cast iron fittings, as
the corrosion will damage the chiller. For chillers with deionization cartridges or high purity
plumbing Boyd recommends the use of either stainless steel or nylon fittings.
4.
Remove water filler cover on top of the unit to access the reservoir.
5. Fill the reservoir. Use the reservoir sight tube on the front of the unit to see the coolant level
in the tank as you are filling. Be sure to allow for the volume of coolant needed to fill the
cooling lines between the chiller and the equipment, if they were not filled with coolant before
installation.
6.
Centrifugal Pumps must be primed before operation. To prime pumps, disconnect supply line
from rear of chiller, allow air to vent and out of pump head and reconnect line.
For Water Cooled Chillers
7.
Connect facility water to connections labeled "City Water In" and "City Water Out".
Minimum flow rate of facility water is shown on page 14. Facility water flow must be started
before chiller is turned on.
****CAUTION****
Standard RC units may not be compatible with deionized water. Consult Boyd Application
Engineering for deionized water applications.
Connecting Power (for units without heater option)
Connect a 3-conductor SJT type power cord with an IEC 320/C19 receptacle to the inlet power to the
module on the rear of the unit and to an appropriate AC power source. All chillers should use a 12
gauge power cord.

WARNING****
Be sure to provide a proper ground connection.
