AK and 3K Series Installation and Service Instructions
4211-139-A 08-14-2009
The AMEREC steam generator can be hung on a wall
or sit on its base. The best mounting location will
satisfy all or most of the following:
1. The steam line should slope to allow condensation
to drain. Condensation should drain into the steam
2. The steam line should be less than 6 M long.
3 M preferred. Steam lines over 6 M long should be
3. The mounting location should minimize the num-
ber of bends and elbows in the steam line.
4. The generator should be installed in a dry, well
ventilated area. Suggested locations are under a
vanity, in a closet, attic, crawl space or basement.
5. The location should provide clearance for service
and element removal. See diagram 2.
6. The mounting location should allow for a drain hook
7. The generator must be mounted in a minimum 0,2
cubic meter space.
8. The generator should not be mounted in an area
subject to freezing.
Do not mount outdoors.
Protect from freezing.
Unit must be located as to allow
access for service.
The generator will not operate
properly, unless it is mounted level
with the arrows pointed up.
Do not put a shut off valve in the
steam line. Avoid traps and valleys
where water could collect and cause a
steam blockage. The hot steam line
must be insulated against user
Centering the steam pipe is critical in
rooms made of plastic, acrylic, resin,
fiberglass or similar materials.
Allowing the steam pipes to touch
materials not rated for 100°C or
higher will result in damage to these
Do not install the steam head near
bench(es) or where steam may spray
or where condensation will drip on
the user as this will present a scald
The steam pipe entry and any other
entry into the steam room must be
caulked to avoid damage caused by
steam leakage into the wall.
Floor Mounting:
1. In general the width of the unit allows it to sit on
a shelf, across the ceiling joists or on a floor. The
generator must be restrained from moving. Normally
the piping will provide adequate support. If not,
additional support must be provided.
2. All floor installed generators must have provision
for routine draining of the tank.
Wall Mounting:
1. Note the location of the mounting holes on the
back of the generator. The screws must set directly
into studs or equivalent supports. Drill pilot holes on
254 and 305 centers and install the two #10 1½"
screws provided.
2. Carefully hang the generator on the two 305 mm
screws. Tighten the screws.
3. Install two #10 1-1/2" screws through the genera-
tor into the 254 mm holes and tighten the screws to
secure the generator to the wall.
4. Replace the generator's front cover and secure it
with the screws provided.
SECTION 4.5: Water Quality Requirements
The nature of a boiler or steambath generator requires testing of the feedwater to avoid potential
high concentrations of impurities which can cause a deposit or scale to form on the internal sur-
faces. This deposit or scale can interfere with the equipments proper operation and even cause
premature boiler or generator failure. Concentration of impurities is generally controlled by treat-
ing the feedwater and or "blowing down" the generator or boiler when it is not heating. The "blow
down" process involves removing a portion of the tank water with high solid concentration and
replacing it with makeup water.
To insure proper operation, the water supply should be tested prior to operating the equipment.
There are several treatment processes which can be used if you have a problem with hard water.
A local reliable water treatment company can recommend the appropriate treatment if required.
The recommended feedwater quality is listed below.
Feedwater Quality
Hardness, ppm 10 - 30 (.5 - 1.75 gpg)
T-Alkalinity, ppm 150 - 700 (8.75 - 40.8 gpg)
Silica Range, ppm 15 - 25 (.88 - 1.45 gpg)
PH (strength of alkalinity) 10.5 - 11.5
