COMMISSIONING
6.8.1 PREPARATION
Before every start-up, the following points should be observed as laid down in the operating
manual:
– For underframe with rolls (option): Lock all four swivel castors with the footbrake.
– Only metal tanks may be used for product and flushing agents, no plastic tanks.
– Check the permissible pressures.
– Check all connections for leaks.
– Check hoses for damage in accordance with Chapter
.
Connect the compressed air
– Connect the AquaCoat system to the compressed air source (8).
Fill the devices with flushing agent
The devices are tested during manufacturing with oil or other fluids. Possible residues
must be flushed out of the circuits with a solvent (flushing agent) before commissioning.
– Fill the empty device with flushing agent in accordance with Chapter
pump's
operating manual. Suction the product: Increase the air pressure gradually until the
pump starts. Do not let the pump run too quickly while suctioning.
NOTICE
Impurities in the spraying system!
Spray gun blockage, products harden in the spraying system.
Flush the spray gun and paint supply with a suitable flushing agent before commissioning.
6.8.2 COMMISSIONING
CAUTION
Electrical discharge when using coated product tanks!
Risk of injury; product charge not optimal.
Ensure that the metal part of the tank is connected to the potential equalization line
(e.g., remove coating from around the connection point).
Check the unit for leaks
1. Place metallic product tank (14) containing a suitable medium (e.g., flushing agent or
water) in the AquaCoat cabinet.
2. Immerse in tank the suction system (13).
3. Clamp the potential equalization line (22) to the product tank (14).
4. To perform a leak test on the entire installation, the pressure is slowly increased step
by step until the maximum pressure as indicated on the type plate for the system and
product pressure generator fitted is reached.
– "Pump pressure" regulator up to 0.8 MPa; 8 bar; 116 psi
– With product pressure regulator: "Product pressure" regulator up to 0.8 MPa; 8 bar;
116 psi
5. Maintain the pressure for 5 minutes and check all connecting parts for leaks.
6. Reduce the pressure, when the seal of the system has been ascertained.
