tic water needs. Because hot water presents a scald hazard, it is best to set the thermostat at 120ºF or lower and raise it

only if necessary to provide adequate hot water. See Table 9.2 for more information about scalding.

X. MAINTENANCE

The Mega-Stor is an extremely simple device and as such requires very little maintenance. There are, however, several items

which should be checked out on an annual or as needed basis to ensure a reliable supply of hot water:

* On an annual basis, remove the black cover over the handhole and make sure that the handhole cover is leak-tight.

* Make sure that the rest of the boiler and domestic water piping is free of leaks.

* If there is an oil lubricated circulator in the system, make sure that it is lubricated as called for by the circulator

manufacturer.

* The Mega-Stor depends upon the boiler for a source of heat and is therefore only as reliable as the boiler. Make sure

that the boiler is maintained in accordance with the boiler manufacturer’s instructions.

* If a water treatment system is required to keep the water chemistry within the parameters shown in Table 5.1, make

sure that this system is properly maintained.
