Specifications for CTM Water Softeners

Culligan commercial water softeners are designed to remove hardness minerals from water. In order to function properly,
some operational parameters must be followed. They include:
1. An operating water pressure between 35 and 125 psi (241–862 kPa). If water pressure is greater than 80 psi, Cul-
ligan recommends following the IAPMO Uniform Plumbing code section 806.2 by installing a Pressure Regulating
Valve before the system. Operating on high presure for extended periods of time can increase the service frequency
of replacement parts. If water pressure can drop below the minimum water pressure, add a booster pump or operate
the pilot valve using compressed air to maintain a 35 psi (241 kPa) minimum operating pressure.
NOTE If an air compressor is used, it must be "oil free" and set at 10 psi greater than the maximum static
water pressure.
2. Operating temperature between 40° and 120°F or 4.4°–49°C.
3. Clear (non-turbid) water supplies (Less than 5 NTU).
4. Voltage of 120V, 50/60 Hz

Maximum softening performance (minimized hardness leakage) can be acheived using this service flow rate.

The Suggested Progressive Flow Trip Point is simply a suggested flow rate at which point an additional tank will be
2
brought on line if facility flow demand meets this rate. The Culligan GBE Controller will not remove a tank brought on line
by attaining the Trip Point unless the flow is the Trip Point amount for a 30-second period. In the event additional units are
not brought on line or off line when desired, simply adjust the programmed Trip Point. Refer to the revised GBE Program-
ming for Commercial Softeners and Filters (except for HFxN) Manual (P/N 01027295) for more information about the
Progressive Flow mode of operation.
Refill flow rates based on 60 psi inlet/influent pressure and eductor combinations specified per
3
and brine refill flow control inserts specified in
control insert options will change the brine refill times (see
