6 MAGNA1 Pumped liquids The pump is suitable for thin, clean, non-aggressive and non-explosive liquids, not containing solid particles or fibers that may attack the pump mechanically or chemically. In heating systems, the water should meet the requirements of accepted standards on water quality in heating systems. In domestic hot-water systems, we recommend to use MAGNA1 pumps only for water with a degree of hardness lower than approx. 14 °dH.
7 MAGNA1 Installation 7. Installation Mechanical installation Insulating shells The MAGNA1 is designed for indoor installation. The pump must be installed with horizontal motor shaft. The pump may be installed in horizontal as well as vertical pipes. The insulating shells supplied with MAGNA1 pumps are for heating systems and should be fitted as part of the installation.

8 MAGNA1 Functions 8. Functions Selection of control mode System application In systems with relatively large pressure losses in the distribution pipes and in air conditioning and cooling systems.
8 MAGNA1 Control modes H CP3 Selection of pump setting for system type CP2 Factory setting: Intermediate proportional-pressure curve, referred to as PP2. CP1 Q Proportional pressure curve (PP1, PP2 or PP3) Proportional pressure control adjusts the pump performance to the actual heat demand in the system, but the pump performance follows the selected performance curve, PP1, PP2 or PP3. See fig. 8 where PP2 has been selected. See Selection of control mode on page 12 for further information.
8 MAGNA1 Functions Control panel Light fields indicating the pump setting The pump has nine optional performance settings which can be selected with the push-button. See fig. 11, pos. 3. The pump setting is indicated by eight light fields in the display. See fig. 11, pos. 2. 1 TM05 5553 3812 2 TM05 5552 3812 3 Fig. 12 Factory setting, PP2 Button presses Fig. 11 Control panel at first start-up The control panel on the pump comprises the following: Pos.

See fig. 13. The head (pressure) is reduced at falling heat demand and increased at rising heat demand.
9 MAGNA1 Guide to performance curves 9. Guide to performance curves Each pump setting has its own performance curve (Q/H curve). A power curve (P1 curve) belongs to each Q/H curve. The power curve shows the pump power consumption (P1) in Watt at a given Q/H curve. The P1 value corresponds to the value that can be read from the pump display. See fig. 14.
