INSTALLATION.
• CHECK THAT THE SITE VOLTAGE CORRESPONDS WITH THAT OF THE PUMP.
• CHECK THAT FUSES ARE INTACT.
• USE SHORTEST POSSIBLE HOSE IN RECOMMENDED DIMENSION. AVOID SHARP BENDS,
CREASES, AND CONTRACTIONS.
• NEVER LIFT OR PULL THE PUMP BY MEANS OF THE CABLE. SUSPEND THE PUMP BY A
ROPE OR PREFERABLY PLACE IT ON A SOLID BASE.
• THE MAXIMUM PUMP SUBMERGENCE RECOMMENDED IS 20m/66ft.
• THE SPECIFIC GRAVITY OF THE PUMPED FLUID SHOULD NOT EXCEED 1.1 UNDER ANY
CIRCUMSTANCES AND PH RANGE SHOULD NOT VARY BEYOND 2 – 10.
• WINDING WITH RESPECT TO EARTH: MINIMUM INSULATION RESISTANCE SHOULD BE 5
MEGOHMS. WIRE THE PUMP TO THE MAINS CORRECTLY. ALWAYS USE A STARTER OR A
PANEL BOARD. SEE INSTRUCTIONS UNDER "MOTOR PROTECTION" BELOW.
• AT THE STARTING MOMENT, THE PUMP SHALL MAKE A KICK, WHICH IS OPPOSITE TO THE
DIRECTION OF ROTATION OF THE IMPELLER. SHIFT TWO PHASES IN THE POWER
CONNECTION IF THE KICK IS IN THE WRONG DIRECTION. THE CORRECT DIRECTION IS
INDICATED ON THE PUMP COVER AT THE TOP OF THE PUMP. (THIS IS NOT NECESSARY
WITH SINGLE PHASE PUMPS, AS THEIR DIRECTION OF ROTATION IS FIXED AND CANNOT
BE CHANGED. HOWEVER, ENSURE THAT THE CONNECTIONS WITH THE PANEL BOARD
SUPPLIED WITH THE UNIT, ARE DONE AS PER COLOR CODE INDICATED IN THE
PANEL/MOTOR LEADS). SINGLE PHASE MOTOR LEADS: RED-STARTING, BLUE/BLACK-
RUNNING, YELLOW/WHITE-COMMON, GREEN-GROUND.
• THE DIRECTION OF ROTATION CAN BE ESTABLISHED BEFORE IMMERSING THE PUMP IN
WATER. DO NOT HOWEVER, RUN THE PUMP FOR MORE THAN 60 SECONDS OUTSIDE THE
WATER. IMMERSE THE PUMP AND ENERGISE THE UNIT. CHECK THE AMPERES DRAWN BY
THE UNIT. THE AMPERAGE SHOULD BE LESS THAN OR EQUAL TO THE FULL LOAD AMPS AS
INDICATED ON THE NAMEPLATE.
H.R.C. FUSES ARE RECOMMENDED STRONGLY AS PER TABLE BELOW.
MAINS VOLTAGE AT SITE HRC FUSE RECOMMENDED
380 VOLTS 3 PHASE 120 AMPS
460 VOLTS 3 PHASE 100 AMPS
575 VOLTS 3 PHASE 80 amps
1000 VOLTS 3 PHASE 50 amps
MOTOR PROTECTION
ADEQUATE MOTOR PROTECTION MUST BE PROVIDED FOR THE PUMPSET. OVERLOAD, SHORT
CIRCUIT & SINGLE PHASE PROTECTION ARE VITAL FOR ANY INSTALLATION. WE STRONGLY
RECOMMEND USING CONTROL PANELS INCORPORATING ALL THE NECESSARY PROTECTION.
PLEASE CONTACT YOUR NEAREST DISTRIBUTOR OR AUTHORIZED MODY SERVICE CENTER FOR
PRICING AND DETAILS. WARRANTY IS VOID IF PUMPS ARE OPERATED WITHOUT ADEQUATE
MOTOR PROTECTION.
