WATER QUALITY INFORMATION

I N S T A L L E R

For optimum results, the water supply should be tested prior

o installation. If the mineral content exceeds the following

t
recommended limits, various external treatment processes are
recommended to correct the problem.

NOTE: An analysis of the on-site water must be made by a
recognized and reliable water treatment company to ascertain
the existing condition and treatment required.

Poor water quality can affect efficiency or result in steam generator
damage. Water contains impurities in solution and suspension.
These impurities concentrate in the generator. The concentration of
these impurities increases as more feedwater is introduced into the
generator and steam is produced. If the suspended solids are
allowed to concentrate beyond certain limits, a deposit or “scale”
will form on the generator internal surfaces. This deposit can
interfere with the proper generator operation and cause generator
failure. The concentration of these impurities is generally controlled
by the water quality and by periodic draining of the generator.

RECOMMENDED FEEDWATER QUALITY

Hardness, ppm 8 – 85 (~0.5 – 5 gpg)
P-Alkalinity, ppm 85 – 410 (~5 – 24 gpg)
T. Alkalinity, ppm 200 – 500 (~7 – 0 gpg)
pH (strength of alkalinity) 8.0 – 11.4

Every 2 months, or more often in “hard” water
areas, the manual drain valve should be opened
fully flushing out accumulated materials, salts and
other particles which are natural by-products of
boiling water.

The optional AutoFlush System feature automatical­ly drains the MrSteam generator following each use.
A time delay allows the water to cool down (about
two hours) before it drains by gravity for a safe and
gentle operation.

LOCATING THE STEAM GENERATOR

Select a location as near as practical to the steam room. Typical locations include: closet, vanity cabinet,

heated attic or basement.

NOTE:

control must be located accordingly. A 60 foot cable is available as a special order part for iTempo
PN 103990-60 and PN 104117-60 for iSteam

IMPORTANT NOTE: The control cable should be run in a dedicated 1" conduit to facilitate installation and service.

DRIP PAN

MrSteam strongly recommends the use of a drip pan in the
unlikely event of a plumbing leak. Check local plumbing codes
for receptor, trap and vent requirements. Drip pans drain by
gravity. The drip pan is equipped with an integral3/4" fitting.
See page 15 for additional drip pan installation information.

NOTE: Do not plumb the generator drain and drip pan drain
together in such a way that will cause drain water to back into
drip pan.
