NOTICE:
Water hammer is a common reason for pressure-reducing valve failures.
Protective devices should be installed to absorb water hammer for systems with this risk.
Solenoid Valve
The solenoid valve is normally closed (fail closed) and slow closing to prevent water hammer. This device is not adjustable and
does not have any service or maintenance requirements.
Constant Flow Valve
This device automatically sets the water flow rate. This device is not adjustable and does not have any service or maintenance
requirements.
Adiabatic Pre-Cooler Pads
General
Adiabatic pre-cooler pads are saturated with water during adiabatic mode of operation. Adiabatic pre-cooler pads cool entering
air before it reaches the coil. The pads have an integrated distribution section that accepts water sprayed unevenly on top
surface and distributes it evenly across the pad. The air inlet face of the adiabatic pre-cooler pad is protected by a blue anti-
stick coating that protects against algae growth and UV damage.
NOTICE:
The adiabatic pre-cooler pads are made of flammable material and should be
removed when performing hot work on or near the unit. No actions that generate sparks
should be performed on or near the unit.
NOTICE:
Do not
run the unit wet with the adiabatic pre-cooler pads out and the fans on
(thereby getting the coils wet). Wet/dry cycling of the unit in this manner could shorten the
coil life and void the warranty.
