4 PARTS LIST DN06 Identifying Your Watchman Unit Due to the fact that the Watchman unit is a factory stocked product, unique serial numbers have not been applied to the product. It is therefore necessary to identify the specific generation of product by the physical characteristics of the pump and of the receiver. Figure on the following page indicates two types of piping arrangements that have been used for the Watchman. You ll note the Packing Construction and A Style Watchman indicates a discharge pipe that is parallel to the receiver face (a 90 degree discharge from the pump suction). The B Style is piped perpendicular to the receiver face (a 80 degree or in-line discharge from the pump suction). This only applies to the A design receiver configuration. Figure shows cut-away drawings of all three generations of pumps used on the Watchman. The uniquely identifiable characteristics of each generation is the discharge orientation and the number of capscrews used to hold the volute to the motor (or motor bracket). By using these two easily identifiable characteristics, and referring to the following chart, it is possible to identify the style of pump on the unit. Suction to Discharge Orientation No. of Capscrews Packed Pump 90 A Style 90 B Style 80 Figure indicates the parts required to adapt the current B Style pump and motor assembly to replace the older design A Style pump. Note that the adapter piping is about /" wider than the A Style pump and motor discharge position. This can be taken up by use of a short nipple and/or a union in place of the existing discharge piping.

10 PARTS LIST DN06 CONTINUED FLOAT SWITCH ASSEMBLY INSTRUCTIONS APPLICATION For automatically controlling the liquid level in a closed tank by float movement. MOUNTING Screw-in Tank Float Switches are mounted directly to the tank by means of the /" I.P.S. threaded fitting (D). Before screwing this fitting into the tank, loosen Nut (C) so that the fitting (D) is free to rotate in the switch bracket. Tighten the fitting (D) so that there will be no leak past the threads. Then revolve the switch case until it is horizontal and tighten Nut (C). REVERSE ACTION To change, relocate operating link to the opposite slot in base plate and corresponding hole in adjusting plate. ADJUSTMENT Switches are shipped from the factory set for a specified float travel. Reasonable adjustment of float travel can be made in the field by moving adjusting strips () which are held in place by Screws (A) and (B). Loosening Screw (B) and moving upper adjusting strip () will affect the upper limit of float travel only. Loosening Screw (A) and moving lower adjusting strip () will affect the lower limit of float travel. B A CAUTION: Switches are shipped with a bracket attached to the mounting plate. This bracket prevents the float and the rod from moving in the tank during shipment. When installing the system, this clearly marked shipping bracket must be removed and discarded. ITEM NUMBER PART NUMBER DESCRIPTION REQUIRED NUMBER Complete Float Switch with Foat NEMA DA09 Float DA06 * Float Switch Seal Kit 8009 C D MECHANICAL ALTERNATOR ASSEMBLY INSTRUCTIONS APPLICATION Mechanical alternators serve to open and close an electric circuit by an upward and downward float movement. The forces are applied by means of a float operating between different liquid levels. The action is such that two switch units are alternated on successive cycles. If the liquid level continues to rise or fall with one pump in operation, the lever will continue to travel to a further position at which point the second switch will be operated, throwing the stand-by pump across the line. MOUNTING Mechanical alternators are mounted directly to the tank by means of the /" I.P.S. threaded fitting (D). Before screwing this fitting into the tank, loosen Nut (C) so that the fitting (D) is free to rotate in the switch bracket. Tighten the fitting (D) so that there will be no leak past the threads. Then revolve the switch case until it is horizontal and tighten Nut (C). STANDARD OPERATION Contacts are arranged for sump action. In this form the contacts will close on increase in liquid level. REVERSE ACTION To change, relocate operating link to the opposite slot in base plate and corresponding hole in adjusting plate. ADJUSTMENT Switches are shipped from the factory set for a specified float travel. Reasonable adjustment of float travel can be made in the field by moving adjusting strips () which B A are held in place by Screws (A) and (B). Loosening Screw (B) and moving upper adjusting strip () will affect the upper limit of float travel only. Loosening Screw (A) and moving lower adjusting strip () will affect the lower limit of float travel. CAUTION: Switches are shipped with a bracket attached to the mounting plate. This bracket prevents the float and the rod from moving in the tank during shipment. When installing the system, this clearly marked shipping bracket must be removed and discarded.
