LAKOS Waterworks PWC Series Separators

Installation Instructions 

 

1. LAKOS Separators are shipped on skids or in wooden crates.  Support legs (22 ½° low 

profile models only) are detached and included with shipping.  Lifting lugs, located on the 
unit’s side, are provided for hoisting as necessary. 

2. A suitable foundation is necessary to accommodate the LAKOS Separator’s weight 

including liquid (see chart, page 4). Anchor bolts are recommended in the base of the legs 
(low profile) or skirt (vertical profile). 

3. Prior to installation, inspect the inlet/outlet/purge connections for foreign objects 

incurred during shipping/storage. 

4. Inlet/outlet pipe connections to the LAKOS Separator should be a straight run of at least 

five pipe diameters to minimize turbulence and enhance performance. 

5. Proper purge hardware and/or solids-handling equipment is required to flush separated 

solids from the separator.   

6. All LAKOS Separators operate within a prescribed flow range (pipe size is not a factor in 

model selection).  Use appropriate hardware to match the inlet/outlet to system piping.  
Connection hardware for the inlet/outlet is not included with the separator. 

7. Inlet pressure to the LAKOS Separator must be at least equal to or greater than the 

anticipated pressure loss through the separator plus 15 psi (1 bar) plus whatever 
downstream pressure is required. See (page 4) for “Flow vs. Pressure Loss” chart. 

8. Pressure gauges (included) are required at both the inlet and outlet of the separator in 

order to monitor pressure loss and proper flow.  If separator operates with an open 
discharge, a valve (not included) should be installed, after the separator’s outlet to create 
a back pressure of at least 5 psi (0.3 bar). 

9. Winterizing is important if the LAKOS Separator is to remain idle in freezing temperatures.  

Drain liquid as necessary to avoid expansion of water to ice and related damage.
