3.0 UNPACKING
&
INSTALLATION
3.1
Unpacking the Unit
Inspect the contents of the carton. Please notify the carrier immediately if there are any signs of
damage to the controller or its parts. Contact your distributor if any of the parts are missing. The
carton should contain a WebMasterONE and technical support package (contains instruction
manual, Quick Start Guide, CD and USB cable). Any options or accessories will be incorporated
as ordered.
3.2
Mounting the Electronic Enclosure
The WebMasterONE is supplied with mounting holes on the enclosure. It should be wall mounted
with the display at eye level on a vibration-free surface, utilizing all mounting holes for maximum
stability.
The enclosure is NEMA 4X rated, suitable for outdoor installation. The maximum ambient
operating temperature is 120° F (49° C); this should be considered if installation is in a high
temperature location.
The installation site should be in close proximity to grounded AC power, the chemistry to be
controlled, and phone line or Ethernet hub (if applicable).
Avoid locations that are in close proximity to sources of electrical noise (motor starters, power
transformers, variable speed motor drives, radio transmitters, etc.), corrosive fumes or excessive
moisture.
The enclosure requires the following clearances:
Top:
2”
Left:
10”
Right:
4”
Bottom: 8”
3.3 Installation
Plumbing
The WebMasterONE series controllers are supplied with a flow switch manifold designed to
provide a continuously flowing sample of cooling water to the sensors. Please refer to Figures 1
(a-d) below for some typical installation drawings.
Cooling Towers:
Tap off the discharge side of the recirculation pump to provide a minimum flow of 1 gallon per
minute through the flow switch manifold. The sample must flow into the bottom of the manifold in
order to close the flow switch, and return to a point of lower pressure in order to ensure flow.
Install an isolation valve on both sides of the manifold to stop flow for sensor maintenance.
IMPORTANT: To avoid damaging the female pipe threads on the supplied plumbing parts, use no
more than 3 wraps of PTFE tape and thread into the pipe FINGER tight only! DO NOT use any
pipe dope, plumber’s putty or other sealing products that contain diacetone alcohol, as these attack
the flow switch plastic! Use PTFE tape ONLY!
