Water Piping
Local authorities can supply the installer with the proper building and safety codes required for safe
and proper installation.
Install piping with minimum bends and changes in elevation to minimize pressure drop. Consider the
following when installing water piping:
1. Vibration eliminators to reduce vibration and noise transmission to the building.
2. Shutoff valves to isolate the unit from the piping system during unit servicing.
3. Manual or automatic air vent valves at the high points of the system. Install drains at the lowest
points in the system.
4. A means of maintaining adequate system water pressure (expansion tank or regulating valve).
5. Temperature and pressure indicators located at the unit to aid in unit servicing.
6. A strainer or other means of removing foreign matter from the water before it enters the pump.
Place the strainer far enough upstream to prevent cavitation at the pump inlet (consult pump
manufacturer for recommendations). The use of a strainer will prolong pump life and keep system
performance up.
7. Place a strainer in the water line just before the inlet of the evaporator. This will help prevent
foreign material from entering and decreasing the performance of the evaporator.
CAUTION
If separate disconnect is used for the 115V supply to the evaporator heating cable,
mark the disconnect clearly to ensure disconnect is not accidentally shut off during
cold seasons.
8. The shell-and-tube evaporator has a thermostat and heating cable to prevent freeze-up down to
-20°F (-29°C) that should be used if located in a sub-freezing location. It is suggested that the
heating cable be wired to a separate 110V supply circuit. All water piping to the unit must also be
protected to prevent freezing.
