The dryer was designed in such a manner that vibrations that may occur during operation are limited. Therefore, it is
advisable to employ connecting lines (flexible hoses, vibration-inhibiting fittings etc.) which protect the dryer against
possible vibrations in the pipework.
Note!
Contaminated intake air!
In the event that the intake air is strongly contaminated (ISO 8573.1 class 3.-3) or poorer quality, we
recommend the additional installation of a prefilter (e.g. SULLAIR SXT OR SXF), to avoid clogging of the
heat exchanger.
8.5 Electrical connections
Danger!
Supply voltage!
The connection to the electric mains should only be carried out by qualified skilled personnel and must
correspond to the legal provisions in force in your region.
Prior to connecting the device, please check the name plate to avoid exceeding the indicated values. The voltage
tolerance is +/- 10%.
SRHT 20-350 AC dryers are supplied with a power cord and safety plug (two-pole and earth connection).
Make sure that suitable fuses or circuit breakers in accordance with the indications on the name plate are available.
A residual-current device (RCD) with In =0.03A is suggested. The cross-section of the power supply cable must
correspond to the power consumption of the dryer. In this respect, the ambient temperature, the cable laying
conditions, the length of the cables and the requirements of the local electricity supplier need to be considered.
Danger!
Supply voltage and missing earth connection!
Important: ensure that the plant is connected to earth.
Do not use plug adapters at the power plug.
Possible replacement of the power plug must only be carried out by a qualified electrician.
DANGER!
Aftercooler safety thermo-switch!
Qualified personnel should carry out the connection of the aftercooler safety thermo-switch to the air
compressor.
Be sure to check that the air compressor is pressureless and not connected to the power supply.
Use the appropriate cable feedthroughs for the installation work.
8.6 Condensate drain
Danger!
Compressed air and condensate under pressure!
The condensate is discharged at system pressure.
The drain pipe needs to be secured.
