DS170 PILOT

10
The Pilot must be placed in an area which is free from frost and
adverse weather conditions.
It must be placed as close to the heat pump as possible without
exceeding the maximum distance.
The maximum distance depends on the diameter of piping and the
number of elbows used (see «Hydraulic connection» tables).
The 2-core sheathed cable which connects the
Pilot and the heat
pump measures 10m. There is a 20m length available as an optional
extra (Ref.753102).
4 - INSTALLATION
4.1 - Placement choice
The Pilot must be installed on a level
and stable base which is distanced from
appliances used for cooking and other heat
sources.

4.2.1 - Recommendations
A type CB backflow prevention device may be installed. This
device must be at diff erent, non-regulated pressure zones. Check
your national laws and regulations to know if this is an obligatory
requirement. The backflow prevention device is designed to
prevent incoming heating water from entering the drinking water
circuit. It must be connected to the mains drainage system.
4.2.1.1 - Backfl ow prevention device
The output actually needed determines the water fl ow rate of
the heating circuit and allows to calculate the dimensions of the
distribution network.
All necessary measures must be taken to ensure that the installation
can be continuously purged. Automatic air purging valves should be
placed at each high point of the installation, and manual air purging
valves should be installed on each radiator.
A suffi cient fl ow rate should be ensured so that the diff erence in
temperature between the outlet and inlet points does not exceed
6°C. In an installation equipped with thermostatic mixing valves, this
inspection must be done with all taps/valves open.
4.2.1.2 - Cross sections, purging of the
heating circuits
4.2 - Hydraulic installation
