Input Water Quality and Environmental Requirements
The quality of the input water is important as it influences the eectiveness
of the system and the drinking water safety of the disinfected output water.
The input water should be from a potable water source within a range
defined in . Acuva purifiers are eective for microbial (bacteria
such as E. coli) disinfection, while a secondary filtration system is needed
upstream to remove sediments, chlorine, and particulate contamination
from water.

Product Information
The Strike family of modules feature stainless steel outer construction for
structural strength, pleasing aesthetics and water safety.
The Strike I envelope includes a reactor tube and an electronics/optics
head. Outer dimensions and location of features are indicated in .
(Electrical cable length not drawn to scale).
Strike Mechanical Characteristics
: Strike I disinfection module mechanical envelope
The Strike I module includes a 3/8” NPT female thread on the water input and
a ¼” NPT female on water outlet.
The Strike II envelope includes two electronics/optics heads joined by a
reactor tube. Outer envelope dimensions are indicated in .
: Strike II disinfection module mechanical envelope
The Strike II module includes ¼” NPT female thread on both input and output.

Product Information
The Strike modules electrically interfaces via a 4-wire terminated connector
protected with an outer PVC jacket. See and for
dimensions of the cable.
The electrical signal family of the Strike module is accessed via a
connectorized, jacketed cable. See 3. Strike I modules with a single
opto-electronic head have one connectorized lead while Strike II modules
with two opto-electronics heads have two identical connectorized leads.

The electrical characteristics of the Strike module IO are listed in detail in
.
• VCC is the power input to the module.
• The enable is an input to the module to trigger the UV-LED to activate.
• The health indicator is an output from the module signalling the module’s
LED health status.
• Ground acts as the return for VCC and the reference for the indication
and enable signal.
* Wire colour can be Blue/Yellow or Green

Installation Guide
1. Mount unit in desired position for integration. See section
for details.
2. Connect the water inlet/outlet lines using proper fittings. See details
in section . Ensure fittings do
not leak at operating pressures—water leaks can damage the Strike units.
3. Connect the electrical connectors (4-pin connector from each side) to
a proper interface.
•For electrical integrations using Acuva control PCBA 600-0213 see
section .
•For installation direct in OEM equipment please, see section
.
4. Flush UV module at rated flow rate for several minutes to ensure
water entirely floods the disinfection unit.
Overview Steps
Mechanical Installation Steps
MECHANICAL MOUNTING
Strike modules require proper orientation to entirely flood the reactor and
prevent air pocket from becoming trapped in the module. The module can
be mounted in either vertical or horizontal orientations according to 4.
