For effective sand removal, SandMaster must be operated within the recommended flow range for each model (see
product label). Pipe size is notafactorin model selection. Use pipe reduction fittings as necessary to connect to
existing piping. Minimum inlet pressure should be at least 15 psi (1 bar). If operating a variable-flow pump,
separator’s performance will be affectedat flows below the recommended range for any model; LAKOS recommends
that the separator be sized for the highest expected flow rate (or consult factory for additionalconsiderations). Read
all instructions before proceeding.
Installation Placement
1. Separator must be placedbetween the pump and pressure tank of aresidential water well system.
2. Check valve must be between the pump and separator.
3. Pressure switch must be between the separator and the pressure tank.
4. Any tees or diversions of pump discharge flow (such as to sprinklers or other needs) should be installedafter
the separator’s outlet.
Installation Procedures
1. Remove plastic caps from the inlet, outlet and purge connections.
2. Install separator in the near upright position. For best results, allow at least five pipe diameters of straight
pipe to and from the separator’s inlet and outlet connections.
3. Support the separator’s weight independently from the inlet/outlet piping. A LAKOS Mounting Bracket Kit is
recommended, but may be substituted with similar hardware.
