Water Pipes - Immergas MAGIS M4-30 Use And Installation

9.4 WATER PIPES.

All the lengths and distances from the pipes have been taken into consideration.
The maximum admissible length of the cable of the temperature probe is 20 m. This is the maximum admissible dis-
tance between the domestic hot water storage tank and the unit (only for installations with domestic hot water storage
tank). The cable of the probe supplied with the domestic hot water storage tank is 10 m long. To enhance efficiency,
it is recommended to install the 3-way valve and the domestic hot water storage tank as close to the unit as possible.
NOTE
If the system is supplied with a domestic hot water storage tank, see the use and maintenance manual of the domestic
hot water storage tank. If there is no glycol (anti-freeze) in the system, there is a power or pump failure; empty the
system (as shown in the figure below).
Models 4-16kW.
Models 18-30kW.
NOTE
If water is not removed from the system under frozen conditions with the unit idle, the frozen water could damage
parts of the hydraulic circuit.
9.4.1 Check the water circuit.
The units are fitted with a water inlet and outlet for connection to a water circuit.
The units must only be connected to closed water circuits. Connection to an open water circuit could cause excessive cor-
rosion to the water pipes. Only materials compliant with current laws must be used.
Before going on with installation of the units, check the following:
• Maximum water pressure ≤ 3 bar.
• Maximum water temperature ≤ 70°C depending on the setting of the safety device.
• Always use materials that are compatible with the water used in the system and with the materials used in the unit.
