Sterling 682.88107.00 specifications Setup Procedures, Connecting Piping

3-4 Setup Procedures

This section provides the procedures necessary for configuring your portable hot oil temperature control unit.

Configuration of your TCU includes connecting cooling, process and vent piping. We recommend that you carry out these procedures in the order given here.

Note: Before carrying out these procedures, install all equipment as described in this section.

Connecting Piping

Make sure that all external piping is properly sized to reduce external pressure drop as much as possible. Do not install process or water supply/drain piping smaller than the fittings on the unit. If the water supply piping is larger than unit fittings, reduce the pipe size at the unit.

The following table lists recommended Upright TCU pipe sizes.

Connection	Size diameter
	inches NPT	mm (approx.) c
To Process	1”	25.4
From Process	1”	25.4
Cooling Water Supply	¾”	19.1
Cooling Water Drain	¾”	19.1
Oil Drain	½”	12.7
Fill Port	1”	25.4

Note: Always use a backup wrench to support Upright unit piping when making connections. Make sure all external piping is supported independently of the

Upright unit.

The manufacturer recommends that you have strainers installed on the cooling water inlets and customer-supplied shut-off valves on all piping connections. Use common black welded pipe for permanent installations.

The Upright is designed to operate with an open, unrestricted drain line. Steam rapidly expands within the heat exchanger, so any overpressure condition from backpressure or standing columns of water against the drain must be avoided.

If you must use a pipe joint compound, use a compound that can withstand the high temperatures and pressures of your Upright unit. Always insulate all piping to prevent burn hazards and to retain heat. Make sure insulation is properly rated for maximum operating temperatures of your Upright unit.

Piping Considerations for Mobile Installations

Because your Upright unit is fitted with casters, its portability is well suited for multiple applications. You can purchase high-quality flexible metal hose from the manufacturer to enhance the mobility of your Upright unit; state the length you want when ordering.

Although they cause a drop in pressure, you can also install quick disconnects to your Upright unit. However, do not install check valves with quick disconnects unless absolutely necessary!
