Installation BEFORE YOU INSTALL YOUR PUMP Dirt and Scale Plug Pump and Pipes! NOTE: For proper performance, pump MUST be matched to ejector and to well depth. Use shallow well installation for wells up to 25 ft depth to water and deep well ejector for depths up to 130 ft. Step 1. - Page 5 Installation PIPING IN THE DEEP WELL Pump See Figures 7 and 8. Gasket Adapter Flange NOTE: Deep well installations are either single pipe (2” wells) or double pipe (4” and larger wells). In a double pipe installation, the larger pipe is the suction pipe and the smaller pipe is the drive pipe (very deep wells may use suction and drive pipes of the same diameter).

Connect the ground wire first as shown in Figure 12. The ground wire must be a solid copper wire at least as large as the power sup- ply wires. Step 2. There must be a solid metal connection between the pressure switch and the motor for motor grounding protection.

Page 10: Operation
Operation PRIMING THE PUMP NEVER run pump dry. Running pump without water may cause pump to overheat, damaging seal and possibly causing burns to per- sons handling pump. Fill pump with water before starting. NEVER run pump against closed discharge, to do so can boil 1 0 0 water inside pump, causing hazardous pressure in unit and possibly scald- ing persons handling pump. -
Page 11: Operation
Operation Step 4. Once unit has primed and pressure stabilized, slowly open (turn counterclockwise - Figure 14A) regulator valve until pressure falters (pressure gauge needle flutters; pump may become noisy - see 1 0 0 Figure 14B). At this point, close (turn clockwise) regulator valve slightly until pressure stabilizes. -

I have a Sta-rite MSE-6 manufactured in 1994, it has a tapperd shaft, code 1H94. How do I get the correct rebuild for the pump end.
To find the correct rebuild kit for a STA-RITE MSC-6 pump with a tapered shaft manufactured in 1994, identify the specific model and horsepower (e.g., MSC-6 with 1/2 HP, 3/4 HP, or 1 HP). Then match it to the parts listed in the repair parts section. Use the appropriate motor and part numbers shown for your model and horsepower. For example:
- For MSC-6 1/2 HP: Motor part number A300CH
- For MSC-6 3/4 HP: Motor part number A300DH
- For MSC-6 1 HP: Motor part number A300EH
Use these part numbers to select the correct rebuild kit.
