1. Upon delivery of the separator and accessory equipment, inspect the unit(s) for damage to exterior and interior including protective coating. Remove to cover plate, inspect units and determine that all internal baffle plates and internal piping are secure. When removing cover, be careful to lift slowly so as not to damage gasket that is adhered to top flange of separator.

2. Separator must be installed in a level and plumb position for proper system function. Piping to separator must be pitched in elevation of 1/8" to 1/16" per foot, to obtain a proper gravity system.

3. Where air or hydrostatic testing is required, internal pressure must not exceed 1 1/2 pounds per square inch (PSIG) while a soap solution is applied to weld seams. DO NOT draw a vacuum on the vessel. Hydrostatic test consists of filling the separator with water and observe for leakage after typically four hours.

4. Equipment to lift the separator shall be of adequate size to lift and lower the separator without dragging and dropping to ensure no damage to the separator.

5. Separators shall be carefully place in area of final location. If used, cables or chains must be of adequate length (not less than 45o included angle) attached to the lifting lugs provided. A spreader bar should be used where necessary. UNDER NO CIRCUMSTANCES USE CHAINS OR SLINGS AROUND THE SEPARATOR.

6. If electrical accessories are included with the separator, make temporary connections to verify operation before items are installed.

7. Separator shall be filled with clean water as soon as possible after placement of separator in final location.

8. All vent openings must be piped in accordance with governing codes from each connection to atmospheric vent outlet. Compartment vent lines must be vented to prevent build-up of hazardous gasses, and the outlet must be vented separately to prevent siphoning and to keep vented gas out of the effluent system.

9. Customer must provide flame arrestor where required by governing codes or conditions for safety.

10. Extend 3" clean-outs to grade level with pipe extensions and couplings when applicable.

11. Metal or plastic thread or flange protectors should be removed from the unused openings and pipe plugs installed. Pipe plugs and blind flanges (shipped installed in the separator) should be removed from unused openings and reinstalled with proper joint compound or gaskets.

NOTE: McTighe Industries Oil-Water Separators are engineered to operate as highly efficient separating units. However, to achieve the desired separation results, it is imperative that the above installation instructions are strictly adhered to.
