Instruction Manual
The ADH Sirocco AC NEMA automatic air dehydrator is permanently connected
equipment and does not have an internal disconnect device. A readily
accessible disconnect device, short circuit, and current protection shall be
provided by the customer and are not supplied by Environmental Technology,
Inc. If the unit is part of a building installation or may be subject to transient
overvoltages exceeding those for International Electrical Code (IEC) Overvoltage
Category II, then the customer shall also provide additional protection to satisfy
IEC Overvoltage Category III and IV.
AC power shall be provided with protection that complies with UL 1449 and IEC
61643. A branch circuit with a 15A breaker for short circuit protection is required.
When not using the optional Type 1 or Type 2 military connector kits, the power
terminal block is suitable only with 14 AWG copper wire. A 7/8” hole is provided
at the bottom of the enclosure for a conduit connection for the electrical wiring.
The customer is responsible for installing the unit in a secure, Restricted Access
Location, accessible only by personnel qualified to work with this equipment.
INSTALLATION
To install the ADH Sirocco AC NEMA automatic air dehydrator, perform the steps
below.
NOTE
The ADH Sirocco AC NEMA automatic air dehydrator does not have a Power
Switch. For that reason, remember that power is running to the unit as soon as
the power source cable is connected.
At this time, shut off the facility circuit breaker serving the ADH Sirocco AC
NEMA.
1.
Before proceeding with installation, make sure the facility circuit breaker
serving the ADH Sirocco AC NEMA unit has been shut off.
2.
Using four 5/16” mounting bolts, fasten the unit to the supporting wall or
surface. To ensure stable mounting, use mounting hardware of a length
appropriate to the surface or material on or into which the unit is being
installed. The ADH Sirocco AC NEMA automatic air dehydrator unit
weighs 24 lbs (10.9 kg). The installation surface or material must be
capable of supporting a static load of approximately four times the weight
of the unit, or 100 pounds (45kg). Fasten mounting hardware securely.
