Welcome to the Service Manuals Page. While every attempt has been made to cover all of the systems we have sold over the years, and those that we can provide service for, there may be some missing. If you do not find a service manual for a system that you have, please contact our office by e-mail, fax, or telephone, and we will be happy to assist you. Lindsay Manuals are not listed due to the fact that they went out of business several years ago, and new parts are no longer available.

Water softeners are manufactured under many different names and sold to many Original Equipment Manufacturer (OEM) assemblers. Many of these systems are the same valves with slight changes made to them, such as colors, covers, sizes etc. Please look at the pictures we have provided next to each set of manuals, and if yours looks close, open that manual and compare components.

Clack Water Treatment

This is the manufacturer. These valves are sold by many Original Equipment Manufacturer (OEM) suppliers & dealers. Clack has been in the water treatment manufacturing business for over 50 years. Clacks introduction into the water softener valve industry was launched around 2000-2001. This valve is also manufactured with many variations exclusively for different OEM assemblers. Many of the internal parts are all the same, the only differences are the covers & computer boards. These units can also be converted back from a specific design for one OEM to the manufacturer's original standard design.
	WS 1" & 1.25"  This valve was the first valve that Clack launched into the water treatment control valve market. This valve was a 4 across button board with a black cover. The valve was then offered to an exclusive group of OEM assemblers in a proprietary version that had 3 buttons on top, and 2 buttons below. This altered version also came with an exclusive board that allowed full custom programming for these exclusive OEM assemblers. The original 4 button black version also had an alternative board made for other OEM assemblers that had a different custom programming style. A few years later this valve was made custom again for an OEM that changed the style to a square head with some additional output relays & programming known as the Promate 5.0 & 6.0, or PM5 & PM6. Sold by Abendroth Water as WS1, Promate, Promate 1, Promnate 5.0, Promate 6.0, H125, and WateRight ACS. These valves all use the same internal parts, power cords etc, only the boards & covers are different. These valves can also be converted back to the manufacturers original design.
	WS 1.5" This valve was the first  1 1/2" valve that Clack launched into the water treatment control valve market. This valve has many of the same parts as the valves listed above, only the valve has higher flow rates. Sold by Abendroth Water as H150 and AB150.
