Equipment Precautions
NOTICE
•
Drain all water piping feeding the adiabatic pre-cooler to avoid stagnant water conditions.
•
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.
•
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.
•
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.
•
To prevent excessive degradation, do not attempt to remove the adiabatic pre-cooler pads wet.
•
Replace battery with R/C (BBCV2), Part. No. CR2032, rated 3V only. Use of another battery may present a risk of fire or
explosion. Only use the battery type specified in Table 6.
•
Scratches on the control panel PLC motherboard may cause the motherboard to fail. Be careful with the battery
replacement lever and be sure to avoid scratching the motherboard.
•
Changing the controller's parameters may result in an undesired operation of the unit, such as a hunting phenomenon,
premature activation of pre-cooling (and increased water consumption) or delayed pre-cooling activation (fluid outlet
temperatures exceeding the design temperature).
•
Never use chloride or chlorine-based solvents such as bleach or muriatic (hydrochloric) acid to clean stainless steel. It is
important to rinse the surface with warm water and wipe with a dry cloth after cleaning.
•
Do not use steam, high-pressure water, or high-pressure air to clean any component.
