BOILER
Inspection
It is recommended the boiler be inspected for
excessive scale and lime build up on a quarterly
basis. In hard water areas or for steamers heavily
used, a more frequent interval should be used. This
inspection consists of an internal examination and
cleanin
of the boiler, an examination of the two
han
in
descalers, and for lime build up on the
water level probes. Also, a check of all boiler
controls, includin
the pressure switches.
Periodic service must be performed as outlined in
these procedures. See “WATER CONDITIONING”
under “GENERAL”.
WARNING: READ AND FOLLOW THE
INSTRUCTIONS ON THE CLR BOTTLE. USE
PLASTIC OR RUBBER GLOVES TO AVOID SKIN
CONTACT. IF CLR LIQUID COMES IN CONTACT
WITH THE SKIN, RINSE WITH CLEAN WATER.
