5. Information about your pump
Taro Single Phase Self-Priming Monoblocks are
manufactured using high quality raw materials and
components using state-of-the-art manufacturing
facilities and will give trouble-free performance if
properly installed and maintained. These Self-Priming
Monoblocks are compact pumping systems with the
pump and motor mounted on a common shaft. As a
coupling is not required, alignment of the pump and
motor is assured. Installation therefore is quick. Self-
Priming Monoblocks find wide application for water
supply to houses, residential colonies and factories.
Prior to installation, go through this manual thoroughly
and follow the instructions for installation and
maintenance to ensure reliable operation. The Self-
Priming Monoblock should be installed by technically
qualified personnel in compliance with national and
local electrical codes and as per our instructions
in order to avoid electrical shocks, unsatisfactory
performance and / or equipment failure.

9. Pre-installation requirements
Arrangement for Installation
General Installation Precautions
Open the packaging and note down the Serial number and Model for future reference
The pump casing is filled with anti-corrosive liquid and supplied. Drain this liquid. Refill with fresh
water and drain prior to installation
Ensure all fasteners are tightened properly
Use prescribed pipe sizes as mentioned on the product nameplate
Fit the strainer provided
After installation, prime the set before starting the pump
Do not install the Single Phase Self-Priming Monoblock with high static suction lift
It is recommended to assemble the Single Phase Self-Priming Monoblock on a level base with
foundation bolts to prevent the pump and piping from getting stressed
As the Single Phase Self-Priming Monoblock is air cooled, ensure that air flow to the cooling fan,
located at the rear side of the motor, is not blocked
Use a single power cable from the power source to the Single Phase Self-Priming Monoblock. Do
not use a power cable with large number of joints as this can result in a significant voltage drop
During installation, ensure the Single Phase Self-Priming Monoblock is not subject to shock loads
which can damage the pumpset parts
Use the services of a professional and trained mechanic with experience in erecting Single
Phase Self-Priming Monoblocks
Ensure proper safety during installation
Ensure that a level foundation is ready before erection of the Single Phase Self-Priming
Monoblock. Contact the dealer from where the Single Phase Self-Priming Monoblock was
purchased for the motor mounting details for preparing the foundation
OMMM001A 13 2020.01

Note
If you detect damage or discrepancy in the product, contact the dealer from
whom the pump was purchased
Warning
Do not use this pump for oil, toxic, corrosive and flammable liquids. Pumping
flammable liquids could cause explosion
Caution
Ensure suitable precautions are taken while lifting and lowering the product
Caution
Use trained professionals to install the Single Phase Self-Priming Monoblock
Warning
Use a power supply cable that has sufficient rating. Factor in low-voltage
operation
Warning
Provide proper Earthing. Improper Earthing can cause electrical shock
Caution
Use a Megger to verify the insulation resistance of the motor. Insulation
resistance should be 20MΩ minimum
Caution
Do not place the Single Phase Self-Priming Monoblock in a location subject to
flooding as water can enter the motor and damage the windings and bearings
Warning
Mount the pump with its axis horizontal
OMMM001A 14 2020.01

Caution
The pump casing houses a mechanical seal. Do not attempt to run the pump
dry as the mechanical seal can get damaged during dry operation. Ensure the
pump is primed and then only run it
Warning
Switch OFF the power before working on electrical lines
Caution
Do not use this pump for pumping liquid exceeding 330C as this may lead to
product failure
Operation Precautions
OMMM001A 15 2020.01

Caution
The supply voltage should be within the specified voltage range.
Water temperature for operation of the pump should not exceed 330C
Failure to observe the precautions given above could cause the pump to
malfunction and may lead to current leakage or electrical shock
Warning
If you find any abnormalities like vibration, noise, smell, etc. from the pump
during trial operation, switch OFF the pump and contact the dealer where this
pump was purchased
10. Installation procedure
Please follow the below procedure to assemble the Single Phase Self-Priming Monoblock:
The following steps are executed prior to installation
Installation:
Measure the Insulation Resistance using a Megger of 500 VDC
Ensure contact points are clean
Connect the measuring cable to the ground conductor
Connect the other measuring cable to phase terminal
Ensure that the insulation resistance, as shown on the Megger, is a minimum of 20MΩ
Prepare a level concrete foundation for mounting the Single Phase Self-Priming Monoblock and
tighten the motor base using the foundation bolts as shown in Fig. 6 below:

Use prescribed pipe sizes as mentioned on the product nameplate
Locate the pump centre line as close as possible to the water surface. Ensure the strainer
is fixed to the end of suction pipe located inside the sump / well. Refer Fig. 7, shown below,
for recommendations:
Use as few pipe fittings as possible in the suction line. Prefer using a bend in place of elbow
Use a good quality strainer to reduce suction losses
During priming, check the pump suction pipe for leakages
In case the pump is used to draw water from a water line, follow the recommended suction pipe
orientation shown in Fig. 8 below.

Electrical Installation
Check the power supply voltage and frequency and compare with the product requirements
specified on the name plate
Observe relevant EB regulations while giving power supply to the motor
Ground the monoblock using the two earth screws provided on the leg of the motor body
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
Electrical wiring work
Warning
All electrical work must be performed by an authorised electrician in compliance with
local electrical equipment standards and internal wiring codes. Improper wiring can
lead to current leakage, electrical shock, or fire.
Earthing
Warning
Be sure to install the ground wire securely. Failure to observe this precaution could
damage the pump and cause current leakage, which may lead to electrical shock.
Caution
Do not connect the ground wire to a gas pipe, water pipe, lightning rod, or telephone
ground wire. Improper grounding could cause electrical shock.
OMMM001A 18 2020.01

The motors are internally wired and pre-connected with the capacitor
Connect phase and neutral to the terminal board
In case of clarification, please refer to the Connection Diagram displayed in the inner side of the
terminal box cover
Connecting the Power Supply
Caution
Observe relevant Electricity Board regulations while powering up the pump set
Warning
Before connecting the wires to the terminal board, make sure the power supply is
properly disconnected. Failure to do so may lead to electrical shock, short, or injury
caused by the unintended starting of the pump
Caution
Do not use damaged cables, power plugs, or loose power outlets. Failure to observe
this precaution could lead to electrical shock, short circuit or fire
Supply connection to single phase monoblock
OMMM001A 19 2020.01

Checking direction of rotation
Danger
Hazardous voltage will cause death, serious injury, electrocution.
All electrical work must be performed by an authorised electrician, in
compliance with local electrical equipment standards and internal
wiring codes.
Ensure pump is primed
The direction of rotation is clockwise looking from the rear end
In case the direction of rotation does not clockwise, return the set back to the dealer from where
it was purchased
