N/S= Not Shown on diagram.** There is one cable per DPS (see code 33). Each cable is 16 ft. of the above referenced p/n.*** Quantity is 8 on WSC/TSC units, 10 on HSC units.**** There are two cables. Each made from 15 feet of the above listed p/n.***** Quantity is 5 on WSC/TSC units, 7 on HSC units.1 Cables contain 90° fitting p/n 000916900 and Anti- Short bushing p/n 047356401.2 See Starter section for all starter- related cables and mounting components. 3 CS07, CS08, CS09, CS10, US02, US03, US04, US05 [ US09 & US10 on HSC units only].4 Paste for sensor well is p/n 735026315. This well was used with sensor p/n 073007302 until 3/03.5 The CS05 Sensor change resulted in a relocation of the sensor. After 3/03, the sensor is located in the inlet cone (as shown in the diagram). Before 3/03, the sensor was located in the suction elbow.6 Beginning 3/05 the CS05 sensor was redesigned to use a well. The location remained the same. From 3/03 to 3/05 no well was used.7 This cable was used with the original operator interface panel. The new flat screen panel uses a VGA cable and a serial cable which comes with the panel.

Differential Pressure SwitchFactory Mounted & Wired (Code 33= B, C or E)

Switches, Wells, Power Cables, Fittings

NOTES:The water pressure differential switch is an optional component. It is factory installed and wired when code 33= E (evaporator only), C (condenser only) or B (both condenser and evaporator). The switches used for either the MicroTech 200 or the MicroTech II control types are the same as are the wells. However the schematic designations are different. MicroTech 200 units designate the Evaporator & Condenser switches as CHW1 & CH1, while the MicroTech II units designate the same switches as EF1 & CF1. The only component part number difference of note are the power cables.

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).

N/S= Not shown on diagram. 1 The Gaskets for the condenser heads are sold in two parts. The gasket itself is the rim that fits between the head and the vessel tube sheet. 1-pass heads use the rim gasket only. 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 4' of U-Channel. 150 PSI heads use U-Channel part number 070189802, and 300 PSI heads use U-Channel part number 070189801. Water box heads use two gaskets on each end (a total of 4 per vessel), and each end requires 8' of U-Channel. 150 PSI Water Box heads use U-Channel part number 073258603, and 300 PSI Water Box Heads use part number 073258602.

Current Design:10/03 and later

Original Design:Until 10/03

(italicized parts have changed and are no longer available. If any one of these are

required, all must be retrofitted)

NOTE:In late September, 2003 the rear high speed assembly was redesigned. Both designs are shown for reference, however only the current design may be used for replacement parts. The parts involved in the redesign are indicated in the Original Design diagram with italicized reference bubbles. Original and new design affected (italicized) parts DO NOT interchange, and older design parts are no longer available. Replacement of any of the affected parts on a unit built prior to 10/03 requires retrofitting the assembly with ALL redesigned parts.
