GENERAL INSTALLATION PRECAUTIONS

No.
If it is necessary to increase the diameter of the suction pipe, place an eccentric reducer
8
between the isolating valve and the flexible pipe section.
Using elbows will increase the flow resistance. Wide bends will result in lesser flow
9
resistance.
10
The piping must have a level or positive gradient to prevent the formation of air pockets.
The diameter of the drop pipe must be bigger than the diameter of the pump's suction
11
port.
12
Use a foot valve in case of negative suction head.
13
Size pump for correct head.
Place the intake of the suction pipe so that the intake is always submerged to prevent
14
entry of air.
Install a compound gauge at the pump suction and a pressure gauge at the pump
15
discharge.
Do not use this pump for sandy water, oil, toxic, acetic, corrosive and
inflammable liquids. Pumping inflammable liquids could cause
explosion. Warranty is void, if pump is used for other than clear cold
water.
The pump must be fixed firmly by bolts through the holes in the flange
or base plate.
Use good quality pump accessories (Non Return Valve, nipple, pipe,
ball valve, etc..) for better performance and trouble free operation.
If you find damage or discrepancy in the product, contact the dealer
where the pump was purchased or the "AQUASUB ENGINEERING's"
sales office in your area.
