Installation Location

The condensate return system should be
located to permit access to operating controls,
instruments and inspection openings.

The foundation should be level and
designed to support the load. Calculations
should be based upon the maximum or
filled weight of the system.

Rigging

Qualified riggers should be used to place
the system on the foundation. All rigging
equipment must be carefully placed to
avoid damaging or loosening piping,
nozzles and other parts of the assembly.
The system should be securely bolted to
the foundation.

Piping

(Figures 1 and 2)

1. Prior to piping, all foreign material or

debris must be removed to prevent
possible malfunctions. Clean tank by
flushing with hose.

2. Avoid imposing any piping strain on the

pump(s). Provide expansion joints and
independently supported pipe hangers
where necessary.

3. Isolating valves are installed to allow for

cleaning or repairs.

4. Make-up water and pump discharge

piping must be sized in accordance with
any applicable local or state codes.
Sizing should be determined by flows,
pressures, and distances, not pump size.

5. Install a stop valve and two check valves

in the pump discharge line.

6. Vent piping should be vertical, full size,

free of valves, bends or restrictions and
piped to a safe location.

7. Over flow piping should be full size, free of

obstructions and piped to a safe location.
