INSTALLATION

INSTALLATION:

1.  Place pump skid and holding tank on level concrete surface in an enclosed 

area preferably with floor drain.  Place holding tank within a few feet of pump 

close enough to allow 5’ supply hose to reach.  Level pump as needed with 

feet levelers and anchor to concrete if desired. Do not allow pump or tank to 

be exposed to freezing temperatures.  

2.  Place spray bar inside concrete trench, nozzles about 1” below the concrete 

surface.  Level and Anchor into place- allow enough room for connection hose 

or piping to connect to spray bar.  Do not allow spray bar to be exposed to 

freezing temperatures. 

NOTE: Trench will accumulate water and dirt so a drain line needs to be 

installed to wash bay main trench or drain line.

3.  Place Cover over spray bar on lip of concrete trench.  Center slots over nozzles.
4.  Install selector switch remote box and photo-eye to wash-bay wall in front of 

undercarriage trench.  Photo-eye will reach a maximum of 10’, so it needs to 

be placed within this distance of the equipment or vehicles moving by.  Place 

far enough in front spray bar to avoid water spraying photo-eye or remote 

box at least 10 ft. is recommended.
