Lifting Drainpipe
The drainpipe can be lifted 450mm.
When the down gradient of the drainpipe can't be ensured,
after upright lifting, the drainpipe is in the down slope.
Conrming Drainage
The drainage should be conrmed during the test run to make sure that there is leakage at the connection.
The conrmation of drainage should be also performed during the installation in the winter season.
■ After mounting the electrical system, do cooling operation and meanwhile add water and check. Fill 600cc water
with a hose from the injection nozzle. Add the water slowly. Don't add water to the motor of the drainage pump.
