Prior planning is very important before the installation of any types of heat exchangers.
- Adequate foundations and supports should be provided to bear the static weight of the heat exchanger unit, the weight of the units in it, and the dynamic loads due to wind, earthquake, etc. to make sure that heat exchanger will not settle thus causing strains in piping and stresses in the unit.
- Leave enough space to be able to service heat exchanger in a future, such as cleaning, repairs or replacement.
- Piping configuration should allow bypassing of heat exchanger for inspection, cleaning, and repairs. Cooling water piping should be set to allow backflushing to remove deposits.
- Piping should be able to expand and contract freely. It should not transmit fluid pulsations and mechanical vibrations to heat exchanger
- Provide necessary instruments to measure temperatures and pressure next to heat exchanger.
- Do not pipe drain connections to a common closed manifold, as it makes it difficult to check if heat exchanger has been thoroughly drained or not.
During actual installation of the heat exchanger on site take the following steps:
- On receipt of a heat exchanger inspect it for any damage in transit.
- Remove packing and preservative materials if the heat exchanger has been stored prior to installation.
- Set the heat exchanger square and level so that the piping connections can be made without forcing.
- Insulate the heat exchanger if very hot or cold compared to the ambient temperature.
- Pressure test the heat exchanger before starting operation.

Thanks for the advice on installing a heat exchanger. Now I do not need to call an engineer to install my flat plate heat exchanger.
