Locating The New Expansion Tank - Utilitech LET2 Mode D'emploi

4. Read this owner's manual and the installation rules carefully. If you do not follow the safety rules,
the expansion tank will not operate properly. It could cause DEATH, SERIOUS BODILY INJURY
AND/OR PROPERTY DAMAGE.
5. If incoming water pressure to the home exceeds 80 psi, a pressure reducing valve will be required.
Recommended inlet water pressure is 60 psi or less.
6. In order to determine incoming water pressure and for proper adjustment of the pressure
reducing valve, a pressure gauge must be installed between the pressure reducing valve and
expansion tank.
7. The complete piping system, including expansion tank and pressure reducing valve, MUST
be protected against below freezing temperatures. Failure to do so could cause severe
water damage.
8. To safeguard against a possible dangerous malfunction of the expansion tank, review the
installation instructions before putting the water supply system back into operation.
This hydro-pneumatic tank is designed and intended for hot or cold water storage at a maximum
pressure of 150 pounds per square inch gauge (150 PSIG). Any use other than with potable water
or at a sustained or instantaneous pressure in excess of 150 psi is UNSAFE. A pressure relief
valve of adequate size must be incorporated in the water heater system. This expansion tank,
as all tanks, will eventually leak.Do not install without adequate drainage provisions where water
leakage will cause damage. Failure to follow these instructions can cause an explosion and result
in SERIOUS OR FATAL INJURY.
CAUTION: Improper installation and use may be hazardous and can result in property damage.
Improper installation and/or pressure settings will void warranty. Install in accordance with local
codes. Refer to manual for installation and service.

FACTS TO CONSIDER ABOUT THE LOCATION
1. The location selected should be indoors in an area not subject to freezing.
2. The items which should be installed in the cold water line, in sequence from the water heater,
are (1) the EXPANSION TANK (2) a PRESSURE GAUGE and (3) a PRESSURE REDUCING
VALVE, if required. See Figure 1.
