7.4 ELECTRICAL CONNECTION
Equipment is available in various electrical configurations. All customer connections
can be made at the terminal connections located in the customer electrical connection
box on the rear of the dryer. (Refer to General Arrangement and appropriate Wiring
Diagrams.)
A suitable fused disconnect switch or circuit breaker, in accordance with national and
local code requirements, is recommended for all ZEKS equipment. Refer to the
Engineering Specifications section for voltage requirements and load.
7.4.1 ZEKS dryers can be configured for three variations of start modes: Manual Mode,
Automatic Mode and Remote Mode. The instructions below describe the methods
to configure the dryer for a particular Start Mode.
A) Manual Mode (Factory Default) - No modification required to operate dryer in
Manual Mode. Once power is applied, dryer can be started or stopped by
depressing the local ON / OFF pushbuttons located on the front panel.
Never wire directly or connect any additional wires to the compressor
junction box. This will cause severe system malfunction.

7.3 FILTRATION
To protect the air dryer from gross contamination associated with compressor oil and
debris and ensure maximum dryer performance, a prefilter is recommended.
Prefilters and afterfilters sized to your drying application can be provided by ZEKS and
are available factory installed. Call your local distributor to select the filter that best
suits your filtration requirements. In addition to air filtration, condensate discharge
oil/water separators are also available to address stringent EPA regulations.
