Introduction Attention Service Technician: This publication is written specifically for, and is intended to be used by, trained service and maintenance personnel who are experienced in the installation, function and repair of Caliber equipment. Untrained individuals who use this manual assume the risk of any resulting property damage and/or personal injury. WARNING! Electrical shock hazard! Prior to servicing equipment, disconnect power supply to prevent electrical shock.
Specifications SPECIFICATIONS Specifications for CWS2 Water Softeners Caliber commercial water softeners are designed to remove hardness minerals from water. In order to function properly, some operational parameters must be followed. They include: An operating water pressure between 30 dynamic psi and 125 psi (207–862 kPa). If water pressure is greater than 80 psi, Caliber recommends following the IAPMO Uniform Plumbing code section 806.2 by installing a Pressure Regulating Valve before the system.
INSTALLATION Installation Materials With the exception of media containers, open the remaining containers, remove all the components, and inspect them before starting installation. The following are necessary components for installing a CWS2 Softener. Figure 2. Materials Stem Controller w/ Eductor Throat Elbows bracket mounted Plumbing Adapter...

Installation Locate Softener Select a space that is level and allows a sufficient amount of room above and behind the softener tank(s) for service access and plumbing supply and drain lines. Floor surface—Choose an area with a smooth, solid and level floor capable of supporting the operating weight of the softening system Drain facilities—A nearby drain must be capable of handling the water softener discharge flow rates during the backwash cycle of the regeneration process in addition to the maximum flow rates of other equipment...

All soldering must be done on any connections requiring soldering prior to connecting the main control valve.
Installation Install Piping Depending on the type of softener system (such as single, duplex, or triplex) and the installation parameters, required pipe lengths and piping accessories will vary. See “Specifications” on page 6 to aid the installation. If the layout drawings are not sufficient for your application, consult the Caliber dealer for specific installation guidelines.

Table 8 on page 43 are based on 60 psi incoming pressure. When using 18X38 or 24X40 brine systems with 60K or 90K units, the 0.80 flow control should be removed from the brine valve. Figure 15. CAUTION! Clip was designed to stay attached to the valve.
Page 21
Installation Brine System Installation NOTE! The brine system is purchased as an optional item to allow the use of various brine tank sizes to better suit the needs of the user. The softener system is normally regenerated using a timed brine refill, dry or wet salt storage brine system. To properly install the brine system, set the brine tank assembly in a convenient location for ease of service and refill the salt.
Page 22
Installation Tubing Pilot Valve For Pilot Valves operating on water, install tubing and strainer as detailed by the image. Water Operating Pressure must be 30 psi dynamic to maximum of 125 psi static. For Pilot Valves operating on air, install plugs and connect as detailed by the arrows. Air Supply must be at least 10 PSI GREATER than the Highest Water Pressure.

Electrical Controller Circuit Board Layout Wiring Procedures and Diagrams Preparation Loosen the screws securing the controller access cover (see Figure 21) on each controller provided. Cable Routing All input and output connections to the circuit board are 24 Volt or less. Although the cables do not have to be run in conduit, it is necessary that long runs of cable be supported or protected by strapping them to the equipment piping.

Electrical Controller Circuit Board Layout Wiring the Smart Controller Power Cord and 24V Transformer The Smart Controller is powered by a 24 VAC and 2.1 Amps (50 VA) transformer (P/N 01014897, 60 Hz). If there are multiple controls in the system being installed, each controller will require its own transformer. It is recommended that each transformer be plugged into a dedicated 120V circuit.

Accessories Auxiliary Outputs The auxiliary board (Figure 42) comes installed in all CWS2 softeners. It has four 24 VAC outputs for driving 24VAC control valve motors, energizing 24VAC relay coils, or 24VAC solenoids directly. Each solid state triac output is capable of handling up to 4 Amps maximum;...
Accessories Auxiliary Output 5 Relay Board The GBE board offers support for the Auxiliary Output 5 Relay board . To use the relay board, install it onto the back of the GBE board. Refer to GBE Programming document for programming information. . Figure 45.

Accessories Non-Hardwater Bypass Conversion (P/N 01029581) NOTE! The Non-Hardwater Bypass is installed at the factory for the NHWB valves. Remove the tubing from the manifold. Unscrew the manifold from the valve body (16 #3 screws). Use a flat head screwdriver to pry the manifold off the valve body at the 3 pry points indicated by a triangle on the top of the manifold.
Start-Up Start-Up Breakout Cycling The rubber seals in the CWS2control valve need to be cycled before installation startup to eliminate what is known as “breakout friction”, where the O-ring settles into the porous surface of the valve body. This cycling can easily be done while the valve is still in the box, or after the valve is on the tank ready for water pressure at start-up.
Page 37
Start-Up To use Table 6 locate the resin volume of the softener model along the left side of the table. Select a 6, 10 or 15 pound/cubic foot of resin salt dosage amount. Continue reading the table to the right until you find a brine system that provides the salt storage characteristics desired.

Start-Up Initial Backwash of the System In order to properly purge excessive air in the system. The pilot valve will need to be manually cycled following the instructions in the GBE Programming document. The inlet isolation valve should not be fully opened until this step is complete and all air from the system has been purged.
Use only mild soap and warm water to clean the exterior of the unit. Never use harsh abrasive cleaners or compounds which contain acid or bleach. Sonny's recommends Simple Green or an equivalent cleaner. Protect the conditioner and drain line from freezing temperatures.
Preventative Maintenance Suggested Preventive Maintenance Inspection Schedule The Sonny's CWS2 commercial water softener has been designed to provide a good, consistent service life. Routinely inspecting the system may help avoid potentially costly breakdowns related to circumstances outside of the control of the dealer and/or user.
Service Service Serial Numbers The unit has a serial number label located on the side of the pilot enclosure which is on the top of the valve. Do not remove or destroy these serial number labels. The information contained in the serial number is used for completing information on the IQR Form.

Service CWS2 Valve O-Ring Kit Description The Valve O-Ring Kit 01029578 contains all the sealing o-rings needed for rebuilding a valve. The different o-ring sizes and quantities are divided into separate bags within the kit to help with proper placement in the valve. Use Figure 51 Figure 52 to identify the o-rings by part number and placement.

Troubleshooting Guide Troubleshooting Guide Drain Line Flow Control—Service Located on the drain connection of the valve, the purpose of the drain line flow controller is to regulate the up flow backwash required to expand and agitate the resin in the softener. The softener will allow maximum expansion of the resin, while preventing any loss to the drain.

Basic Principles Appendix A - Basic Principles What Is Hard Water? Water is said to be hard when it carries too high a concentration of calcium and magnesium. Acceptable water hardness levels will vary depending on the application. Why Should Hardness Be Removed? Hard water causes scaling and etching which greatly impairs the life and efficiency of boilers, air-conditioning systems, cooling towers, water heaters, refrigeration plants and other equipment using water.
Operation Log Appendix C - Operation Log Use the log provided to maintain a record of the system operation. This can be very helpful in identifying any operation problems or maintenance requirements. Most of this information can be found by going to Diagnostics > Advanced Stats on the GBE Controller. Refer to GBE Programming document for programming information.
