Installation
Upon uncrating the instrument, verify that the instrument and any spare parts on the
packing list have been received and are undamaged.
4.1 Air and Water Cooling Connections
Once the instrument has been moved to its desired location, air, water, and
electrical connections can be made. The air inlet, coolant inlet and drain
connections are each ¼ inch female NPT connections and are located at the rear of
the instrument. ¼ inch compression tube fittings and 5/8” hose barb fittings and
associated tubing are included for your convenience. You may select either
depending on your preference.
Connect the coolant to the connector labeled Coolant Supply on the rear panel of
the instrument. The water or coolant must be clean and free of debris, sediment,
minerals, etc. that could cause major scaling, blockage, premature wear, or
malfunction. Use of a heavy-duty water filter is required. Do not use a corrosive
coolant mixture or any liquid that could damage copper, stainless steel, plastic or
Teflon.
4.1.1
Connecting the Drain Line
Connect the drain line to the connector labeled Coolant Drain on the rear panel of
the instrument. The drain system must be capable of handling hot water up to 212
ºF (100 ºC) or brief surges of up to 400 º F (204 º C) steam for short periods of time
during initial cooling of the instrument. If two or more RP Consistometers are
connected to a common drain line, it is recommended that the drain be 3/8 inch
(10mm) inside diameter, minimum. It is also recommended that the drain system
be all metal.
Connect the air supply to the connector labeled AIR on the rear panel of the
instrument. The air is required to be dry and free from dirt and oil. The air should
be supplied at a pressure of 80-150 psig (5.4 – 10.2 bar). The compressed air
supply is required to be free from moisture and contamination of any kind. A
heavy-duty filter is required to prevent premature wear, scaling, blockage or
malfunction.
4.2 Electrical Connections and Control Box
Electrical connections are made using the receptacle on the rear of the instrument.
A power cord is supplied with the instrument. Please observe the following
precautions when making the wiring connections.
