Water Treatment
Using untreated or improperly treated water in these units may result in
inefficient operation and possible tube damage. Consult a qualified water
treatment specialist to determine whether treatment is needed.
Customer Note
The use of improperly treated or untreated water in this equipment may
result in scaling, erosion, corrosion, algae or slime. The services of a qualified
water treatment specialist should be engaged to determine what treatment,
if any, is advisable. The Trane Company warranty specifically excludes liability
for corrosion, erosion or deterioration of Trane equipment. Trane assumes no
responsibilities for the results of the use of untreated or improperly treated
water, or saline or brackish water.
Water Pressure Gauges
Install field-supplied pressure gauges (with manifolds, whenever practical) as
shown in Figure 15. Locate pressure gauges or taps in a straight run of pipe;
avoid placement near elbows, etc. Be sure to install the gauges at the same
elevation.
To read manifolded pressure gauges, open one valve and close the other
(depending upon the reading desired). This eliminates errors resulting from
differently calibrated gauges installed at unmatched elevations.
