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.

Ensure all parts are present, before discarding any packaging. If any parts are missing, do not attempt to install your Inta Zero anti-freeze valve until the missing parts have been obtained.

Do not allow debris, PTFE tape or any metal particles to enter the system. Important: All plumbing is to be installed in accordance with applicable codes and regulations. Important: When fitting/installing a heat pump system or components it is essential that the correct insulation is used and properly sealed to reduce the heat loss from the system, maintaining the system efficiency. Installation The Zero anti-freeze valve must only be installed in a vertical position, with the outlet facing downwards, to allow the draining water to flow out free from obstructions. The Zero antifreeze valves must be installed outdoors, where the lowest temperatures can be reached if the heat pump is not operating. The Zero anti-freeze valve should be properly insulated and sealed to reduce heat loss. Only the vacuum breaker and discharge point should be exposed. The valve(s) must also not be placed close to heat sources which could interfere with their function. For the valve(s) to work properly, keep the system under pressure at all times. Most installations only require one anti-freeze valve, located outside and at the lowest point in the system. We recommend at least 15cm clearance between the valve and the ground as discharged water could freeze and hinder the operation of the valve. The discharge from anti-freeze valves must be collected in a suitable drain and routed to a suitable collection point. If a second valve is required, Inta recommend leaving at least 10 cm between the valves to avoid water discharging onto the lower valve. >15cm © Intatec Ltd 2023 3 Installation Continued When installed outdoors, the Zero antifreeze valve must be protected from rain, snow and direct sunlight. Inta recommend placing a small cover / hood with 1 open face over the vacuum break. This should prevent interference or debris while still permitting air flow. Do not make any trap connections. If the shape of the connection pipes has the potential to create a trap effect (as shown below), part of the pipe will not be able to drain and frost protection will no longer be ensured. ûû Where the heat pump is elevated so the pipework goes down into a U shape (as shown below), this would then require 2 anti-freeze valves to completely drain all the pipework and system. © Intatec Ltd 2023 4 Maintenance Vacuum Breaker Replacement In the event of a malfunction, the vacuum breaker can be removed. Checking the Vacuum Breaker In the event of a malfunction, or as part of a planned maintenance programme the vacuum breaker can be removed. Using a 20mm A/F spanner remove the vacuum breaker from the anti-freeze valve body. Using a suitable sized spanner remove the cover from the vacuum breaker body. Remove the sealing washer. Invert the vacuum breaker body and the plastic vacuum cap should fall out. If it does not fall out it indicates that the vacuum breaker has not been operating correctly and the vacuum breaker needs to be replaced. If the plastic vacuum cap does fall out check it and the sealing washer for damage and inside the body for debris, if present wash away with clean water. Re-assemble and refit into the anti-freeze valve. Cover Sealing washer Plastic vacuum cap Body Thermostatic Cartridge Replacement In the event of a malfunction, the thermostatic cartridge can be replaced. Using a 26mm A/F spanner remove the cartridge from the body and replace with a new one. Replacement Components Replacement components are available from Inta. Fit only genuine Inta replacement components. © Intatec Ltd 2023 5 Notes: © Intatec Ltd 2023 6 Please leave this Manual for the User To activate your product warranty please visit www.intatec.co.uk and click on Product Registration E & O.E © Intatec Ltd 2023 Intatec Ltd Airfield Industrial Estate Hixon Staffordshire ST18 0PF Tel: 01889 272 180 Fax: 01889 272 181 email: sales@intatec.co.uk web: www.intatec.co.uk 14-02-23
