Electrical connec on
1. Connec on : Use conductors which can carry the maximum current required at the maximum ambient
opera ng temperature, according the type of installa on chosen (see indica on on the electrical
diagram). Use only UL marked copper cables in conformity with NEC (Na onal Electrical Code) and CEC
(Canadian Electrical Code).
2. Appropriate protec on should be installed to avoid over current and possible electrocu on due to short-
circuit before installing the air dryer.
3. Proper grounding should be installed.
4. Permissible
opera ng voltage range: ± 5%
5. Refer to the electrical schema c and direct any ques ons to nano-puri fi ca on solu ons technical
support.
Func on test
Start the air dryer a er the following checks are made:
Inspec on of the components:
1. Is there a problem in the air system and electric circuit?
2. Has the by-pass circuit valve (op onal) been closed?
3. Is the purge system valve open?
4. Is the compressed air pressure su
ffi cient?
5. Is there a di ff eren al between the permissible rated voltage and the interrup ng capacity of the fuses
and the circuit-breaker?
Opera ng procedure
Press the “ON” power bu on (press the bu on of the controller in the front and hold for 5 seconds on CAREL
controllers)
We recommend to start the dryer, prior to opening up the air inlet and outlet valves for fi ve minutes. A er
star ng the unit and running it for fi ve minutes slowly pressurize the dryer to avoid any possible damage.
The condensate drain should be cycled to ensure func onality and then slowly open the outlet valve to the
system.
(If compressed air enters the dryer quickly, the pressure could damage parts or instruments).

Important

Wait for more than 5 minutes before restar ng the dryer.
