Getting started

ATTENTION
Before starting, the system must be:
- Rinsed thoroughly to prevent the presence of foreign objects and
impurities which could block the pump.
- Fully filled with the pumped media (water or water-glycol mix).
- Completely purged of air.
- To help to reach this, the pump has a built-in automatic air purge
function. See instructions for activating the air purge function in
section 2 page 15.
- The air purge function can be activated any time during operation
when the presence of air is suspected in the system.
- The air purge function can be activated several times in a sequence
if necessary.
- Audible flow noise indicates that there is still air in the pump.
7.3 Typical setting
The corresponding values are derived from the hydraulic calculation of
the system. If this calculation is not at hand, then the following speed
settings can be used:
Standard single-family home
(approx. 140 m
ecocirc...-4
If the temperature differential between the forward and the return is too
large, increase the power; if the temperature differential is less than
expected, reduce the power even further. (Guideline values: underfloor
heating: 8–10 K; radiator heating: 15–20 K).

Maintenance/Disassembly

Pumps are subject to wear. If the pump is blocked (see section 9) or
grinding noises are audible, check the pump and replace it if
necessary. Procedure:
distance and disconnecting both phase and neutral
wires (overvoltage category III.)
The pump must not run dry as this can result in the
destruction of the bearing in a very short time. Fill it with
liquid before first start-up.
