LINK MASTER
1. Introduction
1.1. About the LINK Master
Thank you for purchasing this House of DURATECH product. To ensure proper operation,
please read this manual carefully before using the device. After reading this manual, be
sure to keep it for future reference.
The LINK Master is a pre-wired central electrical hub, linking all technical pool-related
devices. It makes complex swimming pool installations easier to install and connect.
Making it possible for different devices to work together without adding dedicated cabling
between these devices.
House of DURATECH devices are automatically recognized and set by default. You also
have the possibility to add and connect Multi-Brand devices.
The LINK Master is equipped with multiple ‘smart’ input and output connections for your
pool devices. Giving you full access to the DuraLinkTM connected range of products.
Connect the LINK Master to the internet and it will automatically connect to the Dura-
Cloud App and Portal for easy configuration and operation of the different devices.
The LINK Master ensures efficient and safe operation of your pool.
Be aware that the LINK Master is an exact and sensitive system that must always be
handled with care. During installation, the regulations and provisions applicable for the
country and site of installation must be respected.

- The location where the LINK Master will be installed must be protected from
dust and water in order to ensure that the device functions properly.
- The ambient temperature must be between 0°C and +40°C and must be as
constant as possible.
- The relative humidity at the location of installation must not exceed 90%, no
condensation may occur.
- Direct heat or sun rays on the device must be avoided. The LINK Master is not
suitable for outdoor installation.
- The DuraCloud App and LINK Touch need access to the LINK Master for
configuration of certain settings and calibrations.
- For the DuraCloud App to fully communicate with the LINK Master it needs to
be connected to a ‘router’ device providing wireless (cloud) access. (→2.1.3)
- For the LINK Touch to correctly communicate with the LINK Master it needs to
have an unblocked radio signal.
- Also be aware that for ‘cover operation’ safety reasons the LINK Touch may
only be mounted in a place that allows full visibility of the entire pool.
2.1.1.2. Provisions
Before commencing with the electrical installation, the following supplies need to be avail-
able at the place of installation.
- Power supply 230VAC 32A
- Network cable
