2.0 Introduction to the Magnum Cv and Magnum IT Series

The Magnum CvTM and Magnum ITTM Series valves offer a high degree of installation simplicity and flexibility.

Figure 2.1 provides an overview of the major components and connections of the 2-inch (5.08-cm) Magnum IT valve.

The Magnum valve is available in either a 1-1/2-inch (3.81-cm) (Magnum CvTM) or a 2-inch (5.08-cm) (Magnum IT™) configuration. Throughout

this manual, the 2-inch (5.08-cm) Magnum Cv is shown in illustrations where the model type is irrelevant to what is being demonstrated.

2.1 Assembling the Control to the Magnum Valve

The control and the Magnum valve work together as an integral system to ensure synchronization. Follow the steps outlined below to install the control on the Magnum valve.

Remove Cam Cover

Remove the cam cover by pressing in on the cover release tabs (Figure 2.2). Note the cover locking tab and the slot in the top plate. When you reassemble the cover, the locking tab is placed in the slot first and the cover lowered into position.

Slide Camshaft

Slide the camshaft toward the back of the valve by pressing on the release tab and pulling on the back end of the camshaft (Figure 2.4). The front end of the camshaft will be flush with the mounting plate.

Release Tabs

Locking Tab and Slot

Cover Release Tabs

Figure 2.2

Align Camshaft

The camshaft is keyed and should only be engaged or disengaged when in the position illustrated (Figure 2.3). If the camshaft is not in the proper position, rotate the cam assembly counterclockwise until the camshaft arrow aligns with pillow block arrow.

Figure 2.3

Figure 2.4

Mount Control

Mount the control onto the valve by sliding the mounting tabs over the mounting plate. Note that all models of Magnum controls mount to the valve in the same manner (Figure 2.5).

Mounting Tabs

Mounting Plate

Figure 2.5

Engage Assembly

Engage the control by pressing on the release tab and pushing the camshaft into the control (Figure 2.6). Do not force the camshaft. If the camshaft does not slide freely into the control, check the alignment of the camshaft to ensure it is in the proper position

(Figure 2.3). The control indicator must be in the

REGENERATION COMPLETE position for the 942, 942Man, 952, and 962 when engaging the camshaft into the control. The control indicator must be in the BACKWASH COMPLETE position for the 942F, 942FMan 952F, and 962F when engaging the camshaft

into the control. The control indicator must be in the midpoint of the SERVICE position for the 962M and 962S when engaging the camshaft into the control.

Release Tab and

Camshaft

Figure 2.6

Important:

When 942, 942Man, 952, or 962 controls are installed, control dials must be in the REGENERATION COMPLETE position.

When 942F, 942FMan, or 952F controls are installed, control dials must be in the BACKWASH COMPLETE position.

When 962M or 962S controls are installed, control dials must be in the SERVICE position.

To disassemble the control from the valve, reverse the assembling procedure.

Inlet, Outlet and Drain Connections

The inlet, outlet, and drain connections are designed to accept an GE Osmonics supplied CPVC or brass adapter (Figure 2.7). The adapters provide a convenient union for the three connection ports on the valve. In addition, they incorporate a positive O-ring face seal for ease of installation and leak free operation. DO NOT OVERTIGHTEN THE ADAPTERS. As a general guideline, hand tightening the nut onto the valve will be adequate. If additional tightening is required, never exceed a quarter turn beyond the hand tight position.

The outlet of the 2-inch Magnum IT has an integrated turbine. The turbine measures the flow of water through the outlet. This information is used by the control to determine the best time to recycle.

Figure 2.7

No Hardwater Bypass Feature

The Magnum control valve may be configured for “Hard Water Bypass” or “No Hard Water Bypass”. With Hard Water Bypass, unsoftened or unfiltered water is allowed to bypass the Magnum control valve during regeneration or backwash. With No Hard Water Bypass, a valve cartridge ensures that no unsoftened or unfiltered water bypasses the valve during regeneration or backwash.

It is easy to observe which option is installed in the valve. Note that the Hard Water Bypass End Cap has much longer standoffs than the No Hard Water Bypass cartridge. The No Hard Water Bypass assembly will look identical to the other three valve cartridges on the valve and will have a label identifying the cartridge assembly (Figure 2.8).

Hydraulic Output Signal

An optional hydraulic output signal is available on the valve. An optional cam lobe on pilot valve #6 is used on the camshaft assembly to initiate the hydraulic output signal during regeneration or backwash (Figure 2.9).

The hydraulic line pressure signal will be available through the 1/4-inch connection on the back of the valve marked “AUX”. (Remove the tube cap installed for shipping.)

Optional cam lobes available are:

3.0 General Installation Information

Please review the following items thoroughly to ensure an efficient and safe installation of the water treatment system. Page 12 shows typical installation line drawings for the Magnum valves.

Operating Conditions - A minimum dynamic operating water pressure of 25 psig (172 kPa) is required for the Magnum control valve to operate properly. Water pressure is not to exceed 125 psig (862 kPa). In Canada, water pressure is not to exceed 100 psig (688 kPa). Water temperature is not to exceed 100oF (36oC). Do not subject the valve to freezing conditions.

Space Requirements - Allow adequate space for the water treatment system and associated piping. The General Specifications section (pages 7-9) provides the overall dimensions of the control valve as well as the dimensional reference information for each of the connection ports. A minimum of 4 1/2 inches (11.5 cm) front and rear clearance is required for cartridge assembly and removal.

Plumbing - Always follow good plumbing practices and conform to local codes. Check existing pipes for lime and/or iron buildup. Replace piping if heavy buildup exists and initiate the proper treatment to prevent additional occurrences. Locate the equipment close to a drain that is capable of handling the maximum drain flow rate during backwash.

Flexible Connectors - Some tanks expand and contract over the acceptable range of operating water pressures of the Magnum control valve. The use of flexible connectors is recommended on polywound or fiberglass tank installations of 24-inch (60.96-cm) diameter and larger. Follow the tank manufacturer’s instructions for more information.

Inlet and Outlet Piping - Inlet and outlet plumbing should be adequately supported to avoid excessive loads on the valve. Install a manual bypass system to provide for occasions when the water conditioner must be bypassed for servicing.

Drain LIne Piping - To prevent mineral loss during backwash, and to ensure proper operation of the Magnum Cv Series control valve, A DRAIN LINE FLOW CONTROL must be plumbed into the drain line prior to placing the valve in the service mode. Flow controls from 5 to 40 gpm (18.92 to 151.4 Lpm) are available from GE Osmonics and can be easily installed in the drain line (Figure 3.1). Flow controls greater than 40 gpm (151.4 Lpm) must be plumbed externally. Selection of the proper drain line flow control will depend on the tank size and media used for the installation. See Table 10.3.

The following general drain line piping guidelines should be observed:

•1 inch (2.54 cm) or larger piping

•Should not exceed 20 feet (6.1 m)

•Should not be elevated higher than the control valve

•No shut-off valves should be installed in drain line

•Minimal number of elbows and fittings should be installed in drain line

•Piping must be self-supporting

•Install air gap to provide a siphon break

•Flow control should be installed as close to the Magnum Cv Series control valve as possible if an external flow control is used.

Drain Line Flow Control Disk

Figure 3.1

Brining System - The Magnum control valve utilizes timed water refill to add water to the salt tank. A refill tube with check ball is required in the brine tank that will not restrict the refill or brine draw flow rate capabilities of the valve. Although not required, a separate brine valve (safety float) system is recommended for use with Magnum installations. Select a “High-Flow” brine valve that will not restrict the refill or brine draw flow rate capabilities of the valve. The “Performance Data and Charts” section (Section 10.0) of this manual contains flow rate information for various size injectors and refill controllers.

Pilot Drain - During regeneration, a small amount of water (200 ml or 1 cup) is discharged from the 1/4-inch (6.3-mm) tube fitting on the back of the valve marked DRAIN (Figure 3.2). To prevent this water from being discharged to the floor, plumb this connection to a nonpressurized drain or to the brine tank. Do not plug or apply back pressure to the pilot drain at any time.

Crimping the pilot drain line or installing the line to go up, which causes backpressure, will prevent the diaphragm cartridges from shifting properly through the cycles of regeneration or backwash.

Electrical

1.Electrical requirements for the installation will depend on the configuration of the control.

2.The standard North American Series 962 electronic control is supplied with a 12 volt wall mount transformer. Optional wall mount transformers are available in the following configurations: Japanese plug @ 100 volts/50 or 60 Hz, Australian/Argentine plug @ 240 volts/50 Hz, British plug @ 240 volts/50 Hz, European/Italian plug @ 230 volts/50 Hz. Optional transformers must be ordered separately for all international 12 VAC configurations.

3.The standard North American Series 952 impulse controls use 120 VAC or 24 VAC/50 or 60 Hz power.

Lubricants

It is very important that 100% silicone lubricant is the only lubricant used for installing the Magnum control valve. Any other lubricant may cause material degradation and potential failure of the valve components.

NOTE: Some silicone based lubricants contain petroleum-based ingredients. If there is a question about the lubrication that you are using contact the manufacturer of that lubricant.

5.0Control Settings

5.1Manual

Series 942Man Controls

The 942Man represents the maximum in versatility and ease of operation for the manual control valve system. Upgrade to an automatic system is easily accomplished by switching the manual control to a clock or demand control.

DO NOT TURN THE INDICATOR KNOB CLOCKWISE AT ANY TIME.

Regeneration Instructions

1.Move indicator knob COUNTERCLOCKWISE from the Regeneration Complete position to the center of the Backwash (Figure 5.1) position. DO NOT turn the knob clockwise.

Figure 5.1

2.The indicator knob should remain in the Backwash position for the appropriate amount of time. Specific backwash times are determined by the inlet water quality (i.e.: the amount of iron, manganese, turbidity), the amount of time between regenerations, water pressure, and flow. The typical backwash time is 10-15 minutes*. The unit should be in backwash until water at the drain is clear.

3.When the backwash is complete, move the indicator knob COUNTERCLOCKWISE to the center of the Brine/Slow Rinse position

(Figure 5.2). See the “Suggested Brine Draw/Slow Rinse Table” to determine the correct draw/rinse time. Please note that the tables are given at three salting levels and four pressures. The indicator knob should remain in the Brine/Slow Rinse position for the time* indicated in the table.

*Note: The times given are only general guidelines. Adjustment of the times may be necessary for specific applications and conditions.

Figure 5.2

4.When the slow rinse is complete, move the indicator knob COUNTERCLOCKWISE to the center of the Fast Rinse position (Figure 5.3). The indicator knob should remain in the Fast Rinse position for the appropriate amount of time. specific fast rinse times are determined by water quality, clarity of drain water, water pressure, and flow. Fast rinse serves to eliminate excess salt and repack the resin bed for the service run. Typically fast rinse should continue for 5 - 15 minutes*.

Important: If excessive fast rinse time is required to return the service effluent to quality, there could be an underlying cause, such as low pressure, fouled resin bed, fouled injector, etc.

Figure 5.3

5.When the fast rinse is complete, move the indicator knob COUNTERCLOCKWISE to the Refill position (Figure 5.4). Determine the correct refill time* from Table 5.1 below. The indicator knob should remain in the Refill position for the time indicated in the table.

Regenerating Iron Filters - Model 942Man

Refer to Regenerating Iron Filters Model 942 in Section 5.2 for information on this type of system application. All common control settings, control regenerant settings, and regenerant usage which apply to the 942Man control are the same as those used on the 942 control.

When using the 942Man control however, the time of each cycle cannot be predicted exactly. Note the following regeneration cycle parameters:

•Backwash the filter until the drain water flows clear, typically 5 - 15 minutes.

•Regenerant draw continues until the check ball closes to end draw.

•Slow Rinse should continue until there is NO pink color to the drain water flow. This is typically four times that of the regenerant draw time.

•Fast Rinse time continues until there is no pink color to the drain water flow, typically 5 - 15 minutes.

•Refill time is determined by the size of the refill flow control and the amount of regenerant required for a particular size system. Refer to Regenerant Use Table in Section 5.2.
