SECTION 1: MOUNTING THE STEAM GENERATOR (continued)
1. WALL MOUNTING:
Remove the side cover. 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 14-1/2”
(368 mm) centers and install the two #10 1½" screws, provided.
See at right
.
a)
Carefully hang the generator on the two screws. Tighten the
screws.
b)
The generator may be further secured with two screws mounted on
the same 14-1/2” (368 mm) centers as shown.
c)
Replace the front cover with its four screws.
2. FLOOR MOUNTING:
a)
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.
b)
All floor installed generators must provide for routine draining of the
tank and for draining the safety valve’s outlet.
SECTION 2: WATER QUALITY REQUIREMENTS
The nature of a boiler or steam bath 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 surfaces. This deposit
or scale can interfere with the equipment's proper operation and even
cause premature boiler or generator failure. Concentration of impurities
is generally controlled by treating 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.
This is particularly important in areas with high calcium levels and other water quality problems. Calcium build-up
can cause poor steamer performance and damage the heating elements!
Be especially careful to prevent foaming in the steamer’s water! Foaming water will affect the water level
measuring systems in steamers and boilers, causing operation problems and possibly leading to early element
failures!
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 on
the next page.
Recommended Feedwater Quality
Hardness
10 – 30 ppm - (0.5 - 1.75 gpg)
T-Alkalinity
150 – 700 ppm - (8.75 - 40.8 gpg)
Silica Range
15 – 25 ppm - (1.28 - 1.45 gpg)
PH (strength of alkalinity)
10.5 -- 11.5
