d) Make sure the information on the electrical drawings corresponds to your voltage and
frequency. Check the supply voltage and make sure that there is no over or under
voltage exceeding 10% of the nominal value.
e) In all cases, connections to a ground point must be made with correctly sized wire.
32. Frost Protection
a) When the unfired steam generator is installed in an unheated area, frost could cause
serious damage to the generator and also to the water softener (when supplied). The
resin bed will be destroyed when the temperature drops below 32°F.
b) It is therefore, advisable to install protective electrical heating with thermostatic control
switching on the protection as soon as temperature becomes too close to 32°F. Should
this have to be done in a very large building it would be preferable to create a small
cubicle around the generator to reduce the volume to be protected.
c) Should, however, frost protection be totally unpractical, the heat exchanger shell and the
water feed pump must be drained as do the water softener, chemical feed, and positioner
on modulating thermal fluid valve.
