Maintenance and Servicing
When maintaining these units and having such situations where personnel could be hurt by moving parts or by live electrical parts the
ZEPHYR must be isolated by totally disconnecting the electrical supply. It is imperative that the unit cannot be re-started during the
maintenance operation.
Do not maintain a ZEPHYR that is at its normal operating temperature as there is a danger from hot parts.
1. Lubrication (pictures
,
The oil level in the sight glasses (I) should be checked monthly.
The oil level can only be topped up when the ZEPHYR is switched off and vented to atmospheric pressure.
The oil should be changed after 5000 operating hours under normal ambient conditions (see oil drain screws (K)).
The viscosity must correspond to ISO-VG 150 according to DIN 51 519. Designation according to DIN 51 502: CLP HC 150
We recommend the following oil brands: GEAR-LUBE 150 or equivalent oils from other manufacturers (see oil type plate (M)).
Note
If the oil brand is changed, the old oil must be drained completely from the oil chamber.
Old and used oil must be disposed of corresponding with the relevant health, safety and environmental laws.
VLR 400 / 500:
The bearings of the VLR 400 / 500 need to be greased every 5,000 operating hours or at the latest after 2 years with 30 g grease (see two greasing
points (L)). We recommend Klüber PETAMO GY 193 or other equivalent greases (see label for recommended grease (M)).
Note
These greasing instruction is valid for operation at 20° C ambient temperature. At 40° C this should be reduced by 50 %.
2. Protection mesh
The suction capacity of the ZEPHYR can become reduced if the air protection sieve is not maintained correctly.
The build-in protective mesh must be cleaned regularly depending upon the amount of contamination. Cleaning can be carried out by blowing out
with compressed air.
