- General description 12
- Sound pressure level 12
- Storage and operating conditions 12
- As a precaution the pump must be con nected to a socket with earth connection the installation must be fitted with an earth leakage circuit breaker elcb with a tripping current 30 ma the pump must be connected to an exter nal mains switch with a minimum contact gap of 3 mm in all poles if the pump is not installed close to the switch this must be of a lockable type 13
- Checking of direction of rotation 13
- Connection 13
- Electrical connection 13
- For permanent installation it is recommended to fit a union a non return valve and an isolating valve in the discharge pipe if the pump is installed in a pit with a minimum free cable length of 100 mm see fig 5 the minimum pit dimensions must be as shown in fig 2 furthermore the pit should be dimensioned accord ing to the relation between the water flow to the pit and the pump performance fig 2 13
- Installation 13
- Note depending on local regulations a pump with 10 metres of mains cable must be used if the pump is used as a portable pump for different applications the electrical connection should be carried out in ac cordance with local regulations the operating voltage and frequency are marked on the pump nameplate please make sure that the mo tor is suitable for the electricity supply on which it will be used 13
- Pump installation in wells must be carried out by specially trained persons 13
- Pump location 13
- Safety 13
- Start the pump and check the quantity of water or the discharge pressure 4 stop the pump 5 compare the results taken under points 1 and 3 the connection which gives the larger quantity of water or the higher pressure is the correct direc tion of rotation 13
- The installation of the pump must be car ried out by specially trained persons care must be taken to ensure that persons cannot come into contact with the pump impeller 13
- The pump can be used in vertical or horizontal posi tion see fig 3 during continuous operation the motor and the pump inlet must always be completely covered by the pumped liquid fig 3 13
- Three phase pumps must be connected to an exter nal motor starter with differential release the nomi nal current of the motor starter must correspond to the electrical data marked on the pump nameplate if a level switch is connected to a three phase pump the motor starter must be magnetically operated single phase pumps incorporate thermal overload protection and require no additional motor protec tion note if the motor is overloaded it will stop automat ically when it has cooled to normal temperature it will restart automatically 13
- Three phase pumps only the direction of rotation should be checked every time the pump is connected to a new installation check the direction of rotation as follows 1 position the pump so that the impeller can be ob served 2 start the pump for a short period 3 observe the rotation of the impeller the correct direction of rotation is indicated by an arrow on the top of the motor clockwise when seen from the bottom if the impeller rotates in the wrong direction reverse the direction of rotation by in terchanging two of the phases to the motor if the pump is connected to a piping system the di rection of rotation can be checked as follows 1 start the pump and check the quantity of water or the discharge pressure 2 stop the pump and interchange two of the phases to the motor 13

- Adjust the length of the motor cable by coiling it up on a relief fitting so the cable is not damaged during operation fasten the relief fitting to a suit able bracket at the top of the pit make sure that the cables are not sharply bent or pinched note the end of the cable must not be submerged as water may penetrate through the cable into the motor 14
- Continuous operation during continuous operation the pump must always be completely covered by the pumped liquid 14
- Free standing installation 14
- In the case of permanent installation the pit must be cleared of sludge pebbles etc before the pump is installed 14
- Installation on auto coupling 14
- Intermittent operation for pumps supplied with a level switch the differ ence in level between start and stop can be set by adjusting the free cable between the level switch and the pump handle the longer the length of free cable the larger the dif ference in level between start and stop the pump is allowed to run for maximum 5 minutes per 30 minutes without the motor being submerged in the liquid fig 5 14
- See fig c page 50 for free standing installation of the pumps fit a 90 elbow to the discharge port the pump can be in stalled with a hose or rigid pipe and valves in order to facilitate service of the pump fit a flexible union or coupling to the discharge line for easy sepa ration if a hose is used make sure that the hose does not buckle and that the inside diameter of the hose matches that of the discharge port if a rigid pipe is used the union or coupling non return valve and isolating valve should be fitted in the sequence mentioned as seen from the pump side lower the pump into the liquid if the pump is installed in muddy conditions or on un even ground it is recommended to support the pump on bricks 14
- See figs a and b pages 48 and 49 pumps for permanent installation can be installed on a stationary auto coupling and operated completely or partially submerged in the pumped liquid 1 drill mounting holes for guide rail bracket on the inside of the pit and fasten the guide rail bracket provisionally with two screws 2 place the auto coupling base unit on the bottom of the pit use a plumb line to establish the cor rect positioning fasten with heavy duty expan sion bolts if the bottom of the pit is uneven the auto coupling base unit must be supported so that it is level when being fastened 3 assemble the discharge line in accordance with the generally accepted procedures and without exposing the line to distortion or tension 4 insert the guide rails in the rings of the auto cou pling base unit and adjust the length of the rails accurately to the guide rail bracket 5 unscrew the provisionally fastened guide rail bracket fit it on top of the guide rails and finally fasten it firmly to the pi 14

- When the pipe hose has been connected place the pump in its operating position do not lift or lower the pump by means of the electric cable position the pump so that the pump inlet will not be blocked or partly blocked by sludge mud or similar materials it is recommended to place the pump on a solid base see fig 4 fig 4 14
