3.4 CONNECTION TO THE MAINS
DANGER
- High Voltage is present.
PROPERLY HANDLING PROCEDURES MUST BE USED OF ELECTRICAL
SHOCK.
The connection to the mains, to be carried out by qualified personnel, and the safety
systems must comply with local rules and laws.
Before connecting the unit to the electric power, verify that the voltage and the
frequency available on the mains correspond to the data reported on the data plate of
the dryer. In terms of voltage, a
±5% tolerance is allowed.
The dryer comes with a mains connecting cable already installed.
The mains socket must be provided with a
mains magneto-thermal differential
breaker and the cross section of the power supply cables must be suitable sized by
qualified staff in compliance to rules in force and to the consumption of the dryer (see
the nominal values on the data plate of the dryer).
Power the dryer after having checked that the nominal voltage and line frequency are
constant and matching the nominal values of the machine.
The user must provide
the installation with an adequate line protection and a ground terminal
complying with the electrical rules locally in force.
3.5 PIPING ARRANGEMENT
To ensure service and maintenance to the dryer, a three-valve bypass system is
suggested.
3.6 PREFILTERS and AFTERFILTERS
Prefilters, located before dryer, protect the desiccant bed from contamination by oil,
water, pipe scale etc., so to extend the dryer desiccant life.
An automatic drain on the filter is mandatory.
To improve the dryer performance install a complete set of filters upstream of dryer.
A post filter with a filtration rate of 1 micron is recommended to capture the alumina
powder.
