•
Evaporator water connections are grooved.
•
Thoroughly flush all water piping to the unit before
making the final piping connections to the unit.
•
Components and layout will vary slightly,
depending on the location of connections and the
water source.
•
A vent is provided at the chilled water inlet line to
the evaporator. Additional vents at high points in
the piping must be provided to bleed air from the
chilled water system.
•
Install necessary pressure gauges to monitor the
entering and leaving chilled water pressures.
•
Provide shutoff valves in lines to the gauges to
isolate them from the system when they are not in
use.
•
Use rubber vibration eliminators to prevent
vibration transmission through the water lines.
•
If desired, install thermometers in the lines to
monitor entering and leaving water temperatures.
•
Install a balancing valve in the leaving water line to
control water flow balance.
•
Install shutoff valves on both the entering and
leaving water lines so that the evaporator can be
isolated for service.
Evaporator Piping Components
Piping components include all devices and controls
used to provide proper water system operation and
unit operating safety. These components and their
general locations are given below.
