Upright Portable Hot Oil TCUs Chapter 3: Installation 19
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.
Size diameter
Connection 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!
