Maintenance
Maintenance works (approx. every 3 month on request also shorter)
- Verify rotor accumulator regarding hygienic state, damage, corrosion, contamination or foreign objects and if necessary clean.
To clean the rotor accumulator, pressurised air (not higher than 5 bar) or with persistent contamination a high-pressure clea-
ner (only water, no chemical additions) can be used.
In this connection you have to pay attention that the cleaning spout hits the accumulator with an angle of 90°.
Remove dirty water carefully.
- Verify sealing regarding hygienic state, damage, contamination or foreign objects and clean if necessary verify foreign ob-
jects and clean if necessary.
Readjust or rather replace sealing if necessary.
- Verify driving belt regarding wastage and voltage.
Readjustment or rather replacement by authorised company / manufacturer.
- Verify rotor regarding unbalance and lateral truth and balance or adjust if necessary.
- Verify stock regarding forbidden warming, vibrations or noises in stock.
Replacement if necessary by authorised company / manufacturer.

Circulating heat exchanger RWT
Before the start-up of the circulating heat exchanger (RWT), the following items have
to be verified:
- Is the circulating heat exchanger (RWT) assembled safely according to the
installation instructions?
- Are the diffusor and disperse sections circular tightly fixed to the circulating
heat exchanger (RWT) according to the installation instructions?
- Is the circulating heat exchanger (RWT) installed correctly in the system (ve-
rify supply and exhaust air side)?
- Is the direction of rotation of the circulating heat exchanger (RWT) correct (the
rotor turns from the exhaust air side in the supply air side)?
Version with rinse chamber:
The rinse chamber is an air scoop on the exhaust air side and serves to avoid
the co-rotation of the exhaust air in the supply air.
The rotor obligatory has to turn from the exhaust air through the rinse cham-
ber into the supply air, only this way the principle of the rinse chamber works.
- Have all foreign objects and contaminations that could interfere the free run of
the rotor been removed?
- Execute testrun. Rotor must not grind on casing.
- Are all sealing mounted correctly (sealing as near as possible at the rotor
without blocking the free run)?
For electrical installations the regulations of the VDE and the public utility (EVU) are
decisive.
The connection of the driving motor and the corresponding control is only allowed to be
effected by a skilled electrician in connection with the valid regulations (VDE, EVU etc.).
Advice control: for this, please see the corresponding, separate control manual.
Driving motor and rotor bearing do not need any maintenance during standard opera-
tion conditions.
Before starting the maintenance work, the electricity supply has to be interrupted on
all poles and has to be protected against resetting in order that by sudden start of the
rotor by accidental switch-on, automatic cleaning run or automatic restart after power
failure, the people instructed with the maintenance work will not suffer from danger of
bruising and graze by the sudden start of the rotor.
