Jet Monoblock
Installation
Procedure

Prepare a level concrete foundation for mounting the Jet Monoblock and tighten the motor base using
the foundation bolts as shown in Fig. 1(a) to (d). For Bore Mounted Type Vertical Jet Monoblock (TSJ Series),
mount the set on the bore casing pipe shown in Fig. 7(e).

Jet Monoblock Erection Guide

When the pump is started for the first time, it needs to be primed.
• In the HCS 80 / 11 and TDSJ Series, air cock is not provided. The volute casing internal design permits air to rise
towards the pressure valve during the priming process when pouring water through the removed filling plug
on the pressure valve as shown in Fig. 1 (a) and (b). When the pump is primed, further water cannot be added.
Stop pouring water and refit the filling plug.
• In the HCS SJ Series, open the ball valve as shown in Fig. 1 (c), and prime the pump. Shut the valve after priming.
• In the HCS 40/70/90 and TSJ Series, remove the filling plug on the pressure valve and pouring water into
it as shown in Fig. 1 (d) and (e), keeping the air cock open to release air. When the pump is primed, water
continuously flows through the air cock. The pump is now primed. Stop pouring water, close the air cock and
refit the filling plug.
• In case the water level, during priming, in the pressure valve continuously falls, this indicates a leak and to be corrected.
The easiest method of setting the control valve, shown in Fig. 2(a) and (b), for optimum discharge is the visual method.
In this method, the pump set is run and adjusting the Round Head Screw (15) and measuring the discharge. By trial
and error, adjust the Round Head Screw (15) till the flow of water in the discharge pipe is a maximum. Now lock the
Hex. Nut (2) to prevent the Round Head Screw (15) from loosening. To access the Round Head Screw (15), the pressure
valve Cap Nut (1) needs to be removed and then refitted after adjustment to prevent tampering.

3. Ensure The Jet Unit With Foot Valve And Strainer Is Fixed To The End Of Suction
Ensure the Jet Unit with Foot valve and Strainer is fixed to the end of suction and return pipes located inside the
bore well (HCSJ, TSJ, TDSJ Series). For the HCS SJ Series ensure the supplied strainer is fitted at the bottom of the
suction pipe located in the well. Refer Fig.1, shown above, for recommendations.
2. It is essential to ensure the motor has an adequate degree of protection from dust, fumes and water.
Ensure that the motor has no obstruction around it as this can reduce the free circulation of cooling air.
2. Use Prescribed Pipe Sizes As Mentioned On The Product Name Plate

• The motors are internally wired and pre-connected with the capacitor leads with two leads emerging
out from the Terminal Box Cover.
• Only Phase and Neutral need to be connected to these two leads (A1& A2).
7. Power Cable Connection To Non Clog Sewage Pump
• Ground the Single Phase Jet Monoblock.
• Ensure electrical joints, if any, are properly and adequately insulated.
• Connect the cable properly to the starter terminals to avoid loose connections.
• Factor in low voltage operation while selecting cable size.
