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 ( ) (USED ON THE VESSEL WITH THE DPS) AND ( ) (USED ON THE VESSEL WITHOUT THE DPS). NOTES: THE WATER PRESSURE DIFFERENTIAL SWITCH IS AN OPTIONAL COMPONENT. IT IS FACTORY INSTALLED AND WIRED WHEN CODE 33= E (EVAPORATOR ONLY), C (CONDENS- ER 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.
