Ordering Instructions

EASY ACCESS TO SERVICE... Well cap can be removed without disconnecting cables. O-ring seals on spool permit withdrawal of the entire inner assembly simply by lifting. Replacement is equally simple. Spool support eliminates vertical adjustment allowing service above ground.

CORROSION PROTECTION... Spool and Discharge Body are either lead free hot-dipped galvanized or constructed of corrosion resistant material for longer life, less service.

RELIABLE SEAL... Neoprene O-rings between accurately machined lead free hot-dipped galvanized surfaces on the spool and within the unit provide positive seals to ensure maintenance free performance.

O-RING SEAL PROTECTION... Monitor seal protection prevents seal damage during installation and service eliminating potential service costs.

QUICK TO INSTALL... A quality booster pump installation can be made easily and economically without delay for masonry or building construction creating a sound cost savings solution.

ALTERNATIVE SPOOLS (6x7 and 8x10 only)... Spools are available plain or with silent check valves. The Monitor silent check valve has its operating parts automatically exposed when the spool is withdrawn. Spools are supplied with tappings for pressure controls.

WATERTIGHT WELL CAP... Designed to permit removal without disconnecting cables. Watertight cable and conduit sealing is available for additional protection.

HOLD DOWN... Supplied with each unit. Hold-down pipe also serves as lift-out pipe for installation and allowing speedy service.

FROST PROOF... No heating is required. All water passages are below the frost line.

ALTERNATIVE DISCHARGE & INLET CONNECTIONS... Are available to meet your requirements.

EXPLANATION OF PITLESS BOOSTER UNIT
ORDERING NUMBERS
The diagram illustrates the meaning of the various letters and numerals used in Monitor Custom Industrial Pitless Unit ordering numbers. A typical order number and the pitless unit it stands for are shown.

Typical Order Number
6PS67TBWX23F363FS

6	A. The first numeral in the order number indicates the bury depth, in feet, of the unit. Bury depth on all units is measured from the center of the discharge line to ground level. The top of the pitless case extends 12” above ground level as is required by many codes.
PS	These letters indicate the type of pump the pitless unit is designed for. The unit shown is a PS for submersible pumps.
6	B. This numeral indicates the reservoir tank size. 6 is for a 6" I.D. diameter tank.
7	C. This numeral indicates the upper pitless case size. 7 is for a 7" diameter case.
T	D. Indicates the attachment to the reservoir tank is threaded.
B	E. The presence of the letter "B" in the order number indicates the upper pitless case is black pipe.
W	F. Indicates the unit has a watertight cap.
X	G. Indicates spool passages are closed.
2	This numeral indicates the type of spool which the pitless unith has. In this case it is a spool having two silent check valves. Avaialable with 6 and 8 inch tanks only.
3	H. Indicates the size of drop pipe in inches.
F	I. Indicates the discharge connection is flanged.
3	J. Indicates the size of discharge pipe in inches.
6	K. Indicates the length of the reservoir tank in feet, and is measured from the center of the disharge line to the bottom of the unit.
