MODIFICATION OF AN UL LISTED PRODUCT
MTA chillers feature an electrical cabinet designed and wired in compliance with the UL508A standard for electrical
enclosures. The UL compliance allows this MTA equipment to meet local code requirements in most locations in the US and
Canada. When a UL Listed product is modified, retrofitted or altered in any way after it leaves the factory, it is necessary to
verify if the product continues to meet the applicable certification safety requirements.
If a modification made to the product in the field (outside of the MTA factory) does NOT affect the electrical characteristics
of the panel installed on the machine, then the UL Listing is not affected and the UL label that was placed on the product at
the factory can remain. Some examples include:
- Making the remote ON / OFF connection (to terminals provided in the panel)
- Making the alarm relay connection (to terminals provided in the panel)
- Making remote terminal connection (to terminals provided in the panel)
- Replacement of panel components with equal components
If a modification made in the field DOES affect the electrical characteristics of the panel installed on the machine, it is not
possible for UL to confirm that the product continues to meet the applicable certification safety requirements. In this case
the field modifications must be specifically inspected and recertified by the appropriate UL agency. Some examples include:
- Replacement of panel components with components that are different than those originally supplied
- Replacement of motors (or other current-drawing devices) that involve the change of components inside the panel
- Addition of devices not provided for by MTA
- Addition of electrical loads not foreseen by MTA
In this case it is the responsibility of the AUTHORITY HAVING JURISDICTION to assess the acceptability of modifications
and/or to determine if modifications are significant enough to require a member of the UL field engineering services staff to
evaluate and/or recertify the modified product. Anyone directly involved with a product (including manufacturers, owners,
contractors, and regulatory authorities) can request a Field Evaluation.
For further clarification, contact MTA USA or visit the UL's Web site at www.ul.com/field.

When first starting after a stop of several days, ensure that the casing heating element of each compressor is switched
on for at least 12 hours before pressing the start button.
ATTENTION

The pressure limiting valve is factory set, according to the pump nominal flow operating at a standard voltage of 460V/
3Ph/60Hz.
Before using the unit it is necessary to set the limiting valve according to the plant nominal flow and according to the power
supply.
Units in the TAEevo Tech range are equipped with an electronic controller that manages correct operation of the appliance on
the basis of signals read on the analogue and digital inputs.
This quick guide contains a list of the main functions of the electronic board. For more detailed information consult Chapter 7
"Electronic controller".
