Technical Specification - Inta ZERO114 Installation And Maintenance Instructions Manual

Introduction
The Inta Zero is a unique anti-freeze valve designed to protect heat pump systems operating
with water.
Designed to discharge when the system water temperature goes down to 3˚C preventing ice
from forming in the heat pump circuit that could cause breakdown or costly damage to the
system.
The Inta Zero has been designed and engineered to avoid negative influences from low
ambient temperatures by directly positioning the element in the system water flow, permitting
accurate system discharge only when its truly needed.
A protective ring has been included in the construction to prevent system debris clogging the
operation of the valve.
Double O-rings and reduced surface friction treatment on the operating member also ensure
correct operation and reliability time after time.
These instructions cover the installation, operation and maintenance. Please read the enclosed
instructions before commencing the installation of this product, please note;
We recommend that the installation of any Inta product is carried out by an
approved installer.
It is recommended, especially in hard water areas, that a water softener such as the ActivFlo or
ActivFlo lite be fitted to reduce the risk of calcium deposits forming.
