GENERAL INFORMATION:

Lift-Out Models: These instructions cover the SRA23, SRA-4040, SRAX-23 and SRAX-4040 guide rail systems. The SRAX-23 and SRAX-4040 are Factory Mutual approved  and listed for hazardous locations Class 1, Division 1, Groups C and D. The SRA-23 and SRAX-23 are designed for all Myers 3 inch horizontal flanged discharge pumps. The  SRA-4040 and SRAX4040 are designed for 4 inch horizontal, flanged discharge pumps weighing less than 225 pounds.
General Construction: The base on all the models is made of ASTM A536 ductile iron. The mounting flange on all of the models is made of ASTM A48 Class 30 cast iron.  The rail guide, locating pins, and all fasteners are made of 300 series stainless steel. Gaskets are constructed of neoprene rubber material. Both the 3 and 4-inch elbows are  constructed of ASTM A48 Class 125 cast iron. The hazardous location models have 260 yellow brass sleeved onto the locating pins and facing the mounting plate to meet the  nonsparking requirements. Lift-Out Chain: Myers offers lift-out chain packages for each pump we manufacture. Packages vary depending on the pump design and  requirements. Each lift-out chain package is designed to mount to the top of the pump and allow the pump to be safely hoisted up the guide rail.
Rail Support Brackets: The SRA-33/SRAX-33 and SRA-4040/SRAX-4040 are designed to use 1-1/2″ standard pipe for guide rails. A top rail support bracket is available to be mounted to the hatch frame.
Intermediate brackets are available for deep basins.
It is recommended that if the rail length is over 21 feet, an intermediate bracket be installed. After every additional 20 feet of rail, another intermediate bracket should be used for proper rail support.
Basin Covers: Myers has several types of basin covers available for use with either fiberglass or concrete basins. Basin hatch type covers are available in either steel or  aluminum construction. The basin cover frame is designed to allow for mounting of rail support brackets.
Basin Bottom: All cement pipe basins must have a smooth level troweled bottom for level mounting of discharge casting.
Junction Boxes: If a junction box is used in a hazardous location, it must be a hazardous location approved type with hazardous location cord connectors. Wires from the  junction box must pass through a hazardous location seal connector.
Level Sensing Controls: Intrinsically safe type float controls are recommended for all applications and required for hazardous location service. An intrinsically safe control  panel relay will limit the current and voltage to the level controls. A Myers control panel can be supplied with this type circuitry.

The float level controls maintain the basin sewage water level by controlling pump turn-on and turn-off levels.

1. The lower turn-off control should be set so that the pump stops at approximately the top of the pump. Consult the factory for any settings below this point.

2. The upper turn-on control should be set above the lower turn-off control. The exact height between the two controls is determined by the number of pump starts  desired and the depth of the basin.
   A maximum of 10 starts per hour should not be exceeded.

3. The override control is set at a specified height above the upper turn-on control.

4. The alarm control is set about 6″ to 12″ above the override control.

5. No control should be set above the inlet invert.

Valves: It is recommended that all check valves and shutoff valves be mounted outside the sump – in a valve box. See typical drawing detail. Shutoff valves should be of the  water works approved type with resilient rubber disk seat.
CAUTION: After the pump is installed and sewage has entered the basin there is danger. Sewage water gives off methane and hydrogen sulfide gases, which are poisonous.  Never enter a wet well unless the proper confined space entry procedures are followed.

INSTALLING RAIL SYSTEM PARTS

Mounting Cover, Discharge Base and Rails

1. Set concrete cover with hatch opening in position.
2. Bolt top rail support plates, to hatch frame. Stainless steel bolts are screwed through frame angles when shipped and nuts are provided to hold the plate. Pipe supports have vertical slots so that they can be adjusted for final fit on rails. The plate has slots so the two plates in a duplex system can be adjusted to obtain required centerto-center distance between pumps.
3. Lower the base or base/elbow assembly into the basin.
4. Position the base elbow assembly by dropping a plumb line from center of pipe supports, located on top rail support plate, to center of tapered pins protruding from the top of the base elbow assembly. Level the elbow flange in two directions, 90˚ to each other. Shims may be required under the base in order to obtain this level condition. Mark the position of the base hold-down bolts through the holes in the base.
5. Move the base aside to allow drilling of the concrete for 3/4″ expansion bolts, 2-1/2″ long. Move the base over the bolt holes and recheck with level and plumb line. Install expansion bolts.
6. Cut the pipe guide rails to the proper length and install them between the pipe supports at the top of the basin and the pins on the base. Guide rails are Schedule 40, galvanized or stainless steel.
7. Install discharge pipe as required by the particular job specifications. If one larger size discharge pipe is required, such as 6″ pipe on a 4″ pump, a reducing elbow can be provided.
   IMPORTANT: DISCHARGE PIPE AND GUIDE RAILS MUST BE PARALLEL IF INTERMEDIATE GUIDE BRACKET IS USED.

INSTALLING INTERMEDIATE GUIDE BRACKET

1. Remove guide rails, and cut a piece from each one. These pipes must be exactly the same length and of a length that will permit installing the intermediate guide bracket  in the desired location.

2. Place the cut pieces of pipe over the guide rail pins  located in the base.

3. Set the intermediate guide bracket in position with tapered guides into pipes. Put U-bolt around discharge pipe and tighten lightly.

4. Measure from joint on tapered plug on intermediate guide bracket to joint of tapered plug on top rail support and cut two rails to this length. Put rails in place and tighten screws in top rail support. Holes are slotted to adjust for any error in rail pipe length.

5. Recheck rails; they must be straight and plumb.
   Move intermediate guide bracket if necessary  to perfectly align rails. Spacers may be added or removed from the intermediate guide bracket to obtain alignment. After  alignment is secured, tighten nuts on U-bolt.

6. If a second intermediate guide bracket is used, the above procedure is followed for installation.

Attaching Mounting Plate to Pump

1. With a gasket between the mounting plate and the pump discharge, attach the mounting plate with the supplied bolts. The mounting plate should be turned so that the  two locating pins are horizontal when attached to the pump discharge.
2. Mount the guide plate to the mounting plate using the two bolts provided.

Installing Pump and Mounting Plate

1. Attach the lifting chain to the pump. This is done by installing two eye bolts, or by installing the lifting bail, provided with the lifting chain package.
   When attaching the chain to the eye bolts, the short leg of the chain is installed on the discharge flange side of the pump.
   WARNING! Do not exceed working load limit of chains and other lifting devices. Do not use chains or lifting devices where failure could result in loss of life. Examine  chains and lifting devices for deformation or damage before and after each lift.

2. A hook is located on the top rail support, to hold the upper end of the chain when not in use.

3. Position pump so the guide rails are located in the slots of the guide plate. Slowly lower the pump down the guide rails to the base. The locating pins (horizontal pins on mounting plate) should come to seat in the inclined surface of the arms. CAUTION: No persons should be in the sump basin when pump is lowered into position!

Air Venting: Air tends to trap in the pump volute when water rises in the sump or when the pump is lowered into water after service. To vent off this air, a small hole is drilled into the pump volute. Be sure this vent hole is clean after any service work on pump. Air venting is not a problem after initial start.
