Installation
- Inlet pipe must be horizontal and firmly mounted.
- Inlet flow may need to be reduced at inlet pressure above 500 kPa [72 P.S.I.].
- Under certain conditions it may be advisable to install a Water Hammer Arrestor.
- Fixed Arm must NOT be bent.
Water level differential between pump turning on and off:
A = 200mm gives 65mm water level drop.
A = 375mm gives 270mm water level drop
NOTE¹: Arm distance Min = 200mm & Max = 375mm
NOTE²: Tank Extenders and Extra Back Nuts are available to provide required 150mm spacing
between tank wall and valve body (See Product Codes above). |
