INSTALLATION.
PUMPS ARE AVAIABLE FOR THREE TYPES OF INSTALLATION:

FOR HORIZONTAL OR VERTICAL MOUNTING FOR DRY INSTALLATIONS. POWER LIMITATIONS
EXIST FOR CERTAIN MODELS AND EXTERNAL COOLING MAY BE NECESSARY. PLEASE CONTACT
FACTORY/SALES IF PUMP IS TO BE USED WITH THIS TYPE OF INSTALLATION.
• CHECK THAT THE SITE VOLTAGE CORRESPONDS WITH THAT OF THE PUMP.
• CHECK THAT FUSES ARE INTACT.
• USE SHORTEST POSSIBLE HOSE OF RECOMMENDED DIMENSION. AVOID SHARP BENDS,
CREASES AND CONTRACTIONS. FOR P TYPE AND D TYPE INSTALLATIONS ENSURE ALL
ACCESSORIES ARE AVAILABLE BEFORE STARTING INSTALLATION.
• NEVER LIFT OR PULL THE PUMP BY MEANS OF THE CABLE. SUSPEND THE PUMP BY A
ROPE/CHAIN OR PREFERABLY PLACE IT ON A SOLID BASE. FOR P TYPE INSTALLATIONS
THE REQUISITE CHAIN & TACKLE EQUIPMENT MUST BE AVAILABLE. PLEASE READ OUR
PUBLICATION REGARDING “P” TYPE INSTALLATION.
• WIRE THE PUMP TO THE MAINS CORRECTLY. ALWAYS USE A STARTER OR A PANEL BOARD.
SEE INSTRUCTIONS UNDER "MOTOR PROTECTION" BELOW.
• WHEN THE PUMP IS ENERGIZED IT WILL 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.
• CHECK LEVEL AND CONDITION OF THE OIL AT SERVICE EVERY SIX MONTHS. IF THE OIL
IS EMULSIFIED BY WATER THE SEALS MUST BE REMOVED FROM THE ROTOR SHAFT FOR
FURTHER ACTION. THE SHAFT SEAL SHOULD BE CHECKED FOR WEAR EVERY 2500 HRS. OF
OPERATION. IF SEAL FACES SHOW ANY SIGNS OF WEAR, THEY SHOULD BE REPLACED.
