Installation

Always use a certified HVACR technician or electrician to perform a COOLNOMIX installation.  Ideally, the person or company that maintains the cooling system is the best resource to install COOLNOMIX since they would have the greatest familiarity with the existing equipment. However, in our experience, very often the installer is different than the person or company who maintains the HVACR system as they have the expertise to install COOLNOMIX properly, which includes making sure that the existing system is being maintained properly. The first time they install COOLNOMIX, it could take up to two hours.  An experienced installer can complete an installation in under one hour.

There are two stages to a successful COOLNOMIX implementation: Site Survey and Installation.

Site Survey

The site survey is typically performed during normal cooling system operations.  A thorough site survey enables a rapid, smooth installation either on the same day or on a different day. Major steps are:

Capture built environment information, including

occupancy / usage characteristics for each cooling space
thermostat model, locations(s), and settings
cooling system nameplate, components, availability of power, controls

Confirm that the existing thermostat(s) and cooling systems are in good working order

Determine

where COOLNOMIX will be installed (e.g. indoors, outdoors) and installation method
where the two sensors will be located and whether they need to be modified or their wiring extended
the power and control connections for COOLNOMIX
materials and tools required for installation

Document decisions and learnings

Installation

Installation is typically performed early in the day in order to be the least disruptive to normal business operation and to finish before the rooftop heats up during the hot part of the day. Major steps are:

Install and configure COOLNOMIX device, including dual sensors and setpoint
Install COOLNOMIX power and control connections
Commission COOLNOMIX using COOLNOMIX Connect
Document installation

Note:  For installations taking place on a different day than the site survey, it is critical to reconfirm that the existing cooling system is in good working order, since one should never install any energy efficiency add-on technology to an electro-mechanical systems that is not in good working order.

If you would like to access the COOLNOMIX AC/AR installation manuals, you must first sign an MNDA form. Shortly after signing the MNDA, you will receive a personalized manual via email.
