2) Antifreeze agent based on ethylene glycol basis with inhibitors.Content >20 to 50 % (for example, Antifrogen N)
3) No ultrapure water: conductivity at 25 ˚C: <800 mS/cm,corrosion-chemically neutral
4) For heating water we recommend application of the VDI 2035 or VdTÜV 1466 standards; otherwise a reduced service life of themechanical seal may be the consequence.

If one of the pumps needs to be ser-viced, the pump chamber can be shutoff by a blind flange so that the systemremains operational.
Blind flange
On Etaline Z pump units equipped with motors of size 180 (18.5 kW) and above,with the motor axis in horizontal position, the motors must be supported.To this end, use the foot fixing holes on the motor housing.
Support
Pump sizes Etaline ZPumpDrive 32-160/... to 80-250/...mounted without feet.
Pump sizes Etaline ZPumpDrive 32-160/...to 80-250/...mounted with three feet(St 37, Accessories).
Pump sizes Etaline ZPumpDrive 100-200/... to 200-315/...mounted with three feet(EN-GJL, Accessories).
If the piping is laid horizontally, the upperpump must be vented through the upperventing connection 6 B.1 and vent valve.After that, the unit will operate without dis-turbance.
If flexible pipe joints (expansion joints) are used or if the pump set is in-stalled with a pump foot, Etaline Z PumpDrive has to be additionally fixed.The list of pump accessories includes appropriate fixing elements.When dismantling the motor the volute casing may remain in the piping.
Horizontal installation, direction of flow from bottom to top
Horizontal installation, direction of flow from top to bottom. Werecommend turning the motors so that the terminal boxes and /or frequency inverters do not point downwards.Pump sizes DN 32 to 80 can be directly installed in the piping inany position, but not with the motor pointing downwards.
