Myers 4 Inch Lift Out Rail Systems

NOTE! To the installer: Please make sure you provide this manual to the owner of the equip ment or to the responsible party who maintains the system.
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 proper confined space entry procedures are followed.
CALIFORNIA PROPOSITION 65 WARNING:
Warning This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.
VALVES
It is recommended that all check valves and shutoff valves be mounted outside the sump – in a valve box. See Typical drawing. Shut-off valves should be of the water works approved type with resilient rubber disk seat.

BASIN BOTTOM

All cement pipe basins must have a smooth, level troweled bottom for level mounting of discharge casting.

BASIN COVERS

Basin hatch type covers are made in either aluminum or steel and for mounting on a concrete basin top or on an aluminum or steel basin cover. When hatch cover is to be mounted on concrete top, it is generally poured in place with the concrete top. Pin lugs are provided to hold the cover in place. Bolts for mounting top rail support are screwed through the cover flange from the back side. This allows the bolts to be cemented in with basin top. All bolts are stainless steel and nuts are provided for securing the brackets. If other than Myers hatch covers are used, dimensions must be similar to the Myers hatch drawing shown. Cover should be drilled and tapped at dimensions shown, and stainless steel bolts installed for mounting top rail support guide brackets. When complete basin cover is steel or aluminum, the cover is secured to concrete basin wall with expansion bolts.

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 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.

8. If the top rail support plate cannot be attached to the top hatch cover frame, a special rail bracket, can be furnished for mounting directly to a pipe cemented in the basin wall. This bracket is set and aligned with discharge base the same as described for the rail guide plate attached to the frame.

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 in 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 pump discharge, attach the mounting plate with the studs and nuts supplied. The mounting plate should be turned so that two pins are horizontal and one pin vertical – pointing up.

Installing Pump and Mounting Plate

1. Check pump rotation if 3 phase. Connect power cords to pump control panel and lay pump on its side so impeller can be seen. Turn all switches to Off position.
2. Close main circuit breaker, then jog manual switch to On and then Off. Note rotation of impeller. Impeller must turn counterclockwise when looking into the inlet of the impeller. If rotation is wrong, interchange any two line leads to the motor. BE SURE MAIN BREAKER IS OFF WHEN THIS CHANGE IS MADE. MARK WIRES SO THEY CAN BE REPLACED IN THE SAME ORDER.
3. Attach lifting chains to pump. This is done by installing to eye bolts provided with lifting chain. The short leg of chain is installed on discharge flange side of 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.
4. A hook is located on the top rail support, to hold the upper end of the chain when not in use.
5. Mount the guide plate, on the vertical pin of the mounting plate. Vertical pin should not be tight; it should be permitted to turn about 1/2 turn. Tighten the two set screws.
6. Position the pump so the guide rails relocated in the slots of the guide plate. Slowly lower the pump down the guide rails to the base. Lower the pumps until the locating pins (horizontal pins on the mounting plate) seat on the inclined surface of arms on the base.
7. The pump is now properly positioned for operation.

FLOAT SWITCH INSTALLATION

1. Level controls are held by support bracket and cords are adjusted for proper depth.
   a. Lower turn-off control should be set so that pump stops when water level is about at the top of the volute.
   b. First turn-on control is set to start pump when level is at height specified above pump.
   c. Second turn-on control of a duplex pump system is set at height specified above first turn-on control.
   d. Alarm control is set about 6″ to 12″ above the highest turn-on control.
   e. No control should be set above basin inlet invert or in front of inlet.
   f. Pump is now completely operational.

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.
