Storage and Handling
Please take care when handling a packaged MEGAFLO Eco Plus. The unit is heavy and must only be moved manually within safe working practices. If
the unit is to be stored before installation, it must be placed on a secure, level surface and in a dry, frost free environment.
Siting the MEGAFLO Eco Plus (See Figure 1)
The MEGAFLO Eco Plus unit must be vertically floor mounted. It can be placed anywhere convenient provided the discharge pipe(s) from its safety valves
can be correctly installed. Areas that are subject to freezing must be avoided. Ensure that the floor is of sufficient strength to support the “full” weight
of the unit (refer to Table 6, page 9 for unit weights). Pipe runs should be kept as short as possible for maximum economy. Access to associated controls,
immersion heaters and indirect controls should be possible for servicing and maintenance of the system.
