Section 4 – Maintenance
Warning
Prior to commencement of any work requiring the removal of cover plates at the
opening of the control panel box, the electrical supply to the SteamPac must be
disconnected. The unit should be off and cool before performing work on any
piping or components.
1. Recommended Water Conditions
a) Following are the recommendations for feedwater and boiler water. Contact your local
water treatment professional for testing and treatment recommendations. It is very
important that a strict water management program be maintained.
b) Feedwater
1. Dissolved Oxygen less than 0.005 ppm
2. pH Value 9 to 11 (tested at room temperature)
3. *Hardness less than 50 ppm in the form of
CaCO 3
4. Oil None
5. Suspended Solids None
6. Organic Matter None
7. Chloride less than 50 ppm
8. Total Dissolved Solids less than 300 ppm
9. Iron 2 ppm max.
c) Boiler Water
1. Phosphate 30 to 50 ppm in the form of PO 4
2. Alkalinity less than 300 ppm in the form of
CaCO 3
3. Chloride less than 50 ppm
4. pH Value 9 to 11 (tested at room temperature)
5. Total Dissolved Solids 400 – 2,000 ppm
6. Iron 1 ppm max.
7. Silica 180 ppm max. in the form of
SiO
2
8. Hardness less than 50 ppm
9. Dissolved Oxygen None
10. Suspended Solids 15 ppm
11. Oil None
ppm = parts per million; CaCO 3 = Calcium Carbonate; PO 4 = Phosphate; SiO
2
= Silicon Dioxide
*1 Grain Hardness = 17.118 ppm; therefore: 70 ppm = 4.10 grains hardness
