Installation and Operating Manual

INSTALLATION
Check the GS Pro-Fi 3 for completeness and any transport damages before start of the installation.
A skilled person must be commissioned to install the unit. This requirement also applies to commissioning,
maintenance and repairs.
Notes on installation
Expert installation under observation of the technical regulations for planning, construction and operation of the
system as a whole is the precondition for faultless functioning of the fuel oil system.
Above all, make sure to observe the following:
•
The pipeline from the tank must be installed in a frost-resisting manner; if necessary, provide for technical
equipment for heating with installation in domes or in the open air.
•
For installation, use only open-end spanners of corresponding width. No gas wrenches may be used.
•
Mount the device free of any tensile, bending, or torsion stress
•
Before installation, check the connections visually for metal chips or other matter. Be sure to remove any
such matter (e.g. by blowing out) to avoid malfunctioning.
•
The bleeder line dimensions should provide for a mean fuel flow rate of 0.2 to 0.5 m/s. If the diameter of the
pipes is too large, low flow rates occur which can result in formation of undesirable gas bubbles.
