Controller must be programmed before shipping. Unit serial number and software code (located on controller label)
are required when ordering to insure proper software installation. Large controllers are standard, there are a few
small controllers in the field (see code 28).
*This control box was used with the original operator interface panel (which is connected to the control box with one
seven-wire cable). A new design faltscreen operator interface panel can be retrofitted for use with this control box
using retrofit kit p/n 300040573.

*Quantities are based on the presence of both DPS (Code 33= B). If code 33= E or C part numbers 651 & 656 quantities are 1 & 4
respectively, and only one cable (411 if C33= E or 412 if C33= C) is used. If only one DPS is used, the well (ref. # 667) has a quanity of 2-
072867501 (used on the vessel with the DPS) and 2- 047441511 (used on the vessel without the DPS).

 Hot Gas Bypass- Until 10/02
Valves, Connectors, Tubing

The Hot Gas Bypass was redesigned in late 2002. The primary changes were the removal of the shutoff valve, the repositioning of the ball
valve, and a new HGBP valve (associated tubing changed as a result).

The Gaskets for Condenser heads are sold in two parts. The gasket itself is the rim that fits between the head and the
Condenser's tube sheet. 1-pass heads simply use the rim. 2-pass and 3-pass heads use the gasket plus a U-channel
that is glued to the rim and fits over the baffles that separate the passes. Each gasket requires 3' of U-Channel part
number 070189802. One-Pass heads use no U-Channel, 2-Pass heads use the U-Channel only on the connection
end, 3-Pass heads use U-Channel on both ends. Water Box heads use two gaskets on each end, and the U-Channel
is p/n 073258603 and the requirements are doubled. The U-Channel adhesive is part number 735026371.
