Safety Precautions - Lydall Affinity User Manual

Safety Precautions

1. Heed all warning labels. Do not remove.
2. Do not operate the chiller with the bonnet removed. The bonnet protects personnel from
rotating parts and hot surfaces and also protects the chiller's components.
3. Connect the chiller to a properly fused disconnect box in compliance with the NEC
(National Electric Code) as well as state and local codes for American usage, or local
and national codes for European usage. Maximum fuses must not exceed the maximum
rating found on the serial tag on the electrical box. The voltage, phase, and frequency of
the power source must also match the requirements specified on the serial tag. To
reduce the risk of electric shock:
Do not remove cover of the remote control box (if included). Refer servicing to properly
qualified and licensed personnel.
Disconnect electrical power before opening the electrical box, except for the checking of
the phase reverse relay or phase monitor if included with this unit (phase reverse relays
or phase monitors will never be included in single phase units). Power must be applied
in order for the phase reverse relay or phase monitor to indicate phase sequence.
Do not operate equipment with damaged electric power cords.
Turn off the chiller and disconnect electric power before servicing or moving.
4. Coolant lines, filters, and other components which connect to the chiller must be capable
of withstanding the maximum pressure that the pump in the chiller can deliver at the
maximum expected temperature.
5. The coolant loop has not been designed for potable water applications. Do not use the
chiller for potable water. Never hook the water lines of a water-cooled unit to a potable
water source or immerse a hose connected to a potable water source in the reservoir
without providing back flow protection. A loss of pressure in the water source could lead
to a back flow of the fluid in the unit, resulting in a possible contamination of the potable
water source.
6. Vapors of some alcohol based antifreezes as well as other coolants may cause
explosion if exposed to flame or spark.
7. Certain antifreezes may be poisonous if ingested.
