13. Ancillary installation notes:
The finished ground level should never be higher than the level indicated on the system. A riser should be
fitted if required, see section 9.
13.1 Ventilation:
Ventilation is crucial to the system and should be installed as per the building
regulations.
13.2Control housings:
Monitoring equipment, alarms, blowers or pumps if supplied, may be placed into separate control
housing. These can be fitted with visual / audio /
alarms along with other equipment. If so, a mains
supply may be required. Mains must be disconnected before maintaining the system. Consideration should
be given to the location and security of the control housing.
13.3 Access:
Once the system has been completely installed, we recommend that access is restricted to the area
around the plant and/or any control housings. Access for maintenance or de-sludging must be available.
