4. Pressure gauges are required at the inlet and outlet of the separator for monitoring and troubleshooting.
A pressure differential reading of 5-15 psi (0.3-1.0 bar) confirms that the separator is operating at its proper
flow range.
5. Use proper isolators (such as plastic fittings) when dealing with copper pipe connections to the separator.
Grounding the separator is also recommended (run wire from separator/bracket to the pump’s earth ground,
for example).
6. When installing LAKOS purge equipment:
a. Manual valve should be installed directly below the separator, before any elbows or turns in the
purge piping.
b. Automatic valve should be installed downstream from the elbow. Valve should not be more than
24 inches downstream from the elbow.
c. Install a manual isolation valve between the SandMaster and the automatic valve. This allows the
manual valve to be closed and/or used as a manual purge valve if/when servicing the automatic valve.
Operation & Maintenance
1. SandMaster must be regularly purged of separated sand. Do not allow separated sand to accumulate and
compact in the separator’s collection chamber. At least weekly purging is recommended. Recommended load
capacity per model:
2. Avoid uphill piping and long pipe runs on the purge line.
3. If manually purging, open purge valve until purge flow runs relatively clear.
4. Automatic purging is recommended at these intervals:
a. Extreme sand content: Purge every 12 hours for 20 seconds
b. Average sand content: Purge every 24 hours for 15 seconds
c. Light sand content: Purge every 24 hours for 10 seconds
5. If SandMaster is subject to long idle periods in sub-freezing conditions, drain separator to allow for water
expansion to ice without damaging the unit. Alternatively, protect SandMaster from freezing with appropriate
insulation.
