GHUR intermediate cooler
Make sure that no dirt or other unknown elements enter the vessel during installation.
Do not remove protective plugs and covers until immediately before installation.
The entire system must be clean before starting the operation. When fitting the tube connections,
make sure that the load from the piping on the connections is kept small and insignificant as the
vessel is not designed to be an anchor point in the piping system. Vibrations must be minimised,
possibly by means of vibration dampers.
Welding must not be carried out on the vessel.
The vessel must be secured against exceeding the allowable pressures and temperatures.
All outer surfaces must have a corrosion resistant surface coating to allow the vessel to be in-
stalled in certain environments without it causing corrosion.
Safety equipment
Before the vessel is put into operation, it must be provided with safety equipment. The manufac-
turer of the refrigeration plant is responsible for the safety equipment as it is not included in the
vessel delivery.
Start-up and operation
Before start-up, make sure that all connections are tight.
To avoid accidents or personal injury, the person responsible for the plant must make sure that
the operating staff is duly trained and instructed before the refrigeration plant is started. The in-
struction should be based on the unit instruction manuals and should include instructions in con-
struction, supervision, operation and maintenance of the system as well as the handling of used
refrigerant.
Evacuation and charging with refrigerant must be carried out in accordance with the description
in the unit instruction manual.
Before operation, the refrigeration plant must be leak tested and inspected by an authorised
person.
Local safety and health regulations must be observed.
The authorised person makes a certificate which must be kept by the user.
Bolted connections
Normal relaxing of the gasketed joints may occur in the interval between testing at the manufac-
turer’s and installation on site. Therefore, all external bolted joints may require retightening after
installation and, if necessary, once again when the vessel has reached its operating temperature.
Note that retightening must never be performed during operation.
It is important that all bolted joints are tightened evenly and in a diametrically staggered pattern.
All bolts must be tightened to the same torque using a torque wrench.
