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 CHW & CH, while the MicroTech II units designate the same switches as EF & CF. The only component part number difference of note are the power cables. *Quantities are based on the presence of both DPS (Code 33= B). If code 33= E or C part numbers 65 & 656 quantities are & 4 respectively, and only one cable (4 if C33= E or 42 if C33= C) is used. If only one DPS is used, the well (ref. # 667) has a quanity of (used on the vessel with the DPS) and (used on the vessel without the DPS).
