?
1.2 Locating Fire Pump Cabinets
Fire Pump Cabinets shall be installed in a Safe Area. A proper placement of a fire pump and related equipment is also intended to provide a relatively safe environment for the equipment operator. Fire pumps must not be located in mechanical equipment spaces, which would expose the fire pump and operator to damage and potential injury.
General requirements:
?
1.3 Pre‐Installation
One of the most important factors to successful operation and maintenance of your pump unit is a correctly performed installation of the unit. A pump unit that has been installed correctly will remain aligned better in the long run, will show less leakage of casing as well as flanges, will show less vibration and will demand less servicing.
Another aspect that will be influenced by the installation of your pump unit is its service‐life. A correctly performed installation will prolong the pump's service‐life and diminish the risk of failures in emergencies.
A bad performed installation may damage a new pump unit severely within a relatively short time.
