Start-up and operation

5 Start-up and operation

5.1 First cleaning

This Fluid Heater was function tested at factory using a test-

medium.

To ensure that no test medium is left in the pump, the entire system should

first be flushed using the solvent recommended by the manufacturer of the

coating to be used.

➤ Disconnect the heater from the power source.

➤ Now complete all steps covering the initial flushing found in the spraying

equipment's Operation manual.

For best results, we recommend flushing the system for approximately one

minute. To avoid any danger of explosion, do not allow the solvent to circulate

for more than 5 minutes and ensure that the amount of available solvent cor-

responds to the size of the pump used. Depending on the pump, at least 8 to

25 liters (2 to 6.5 gallons) of solvent are necessary.

5.2 Pressure testing

The maximum operating pressure of the Fluid Heater must be

equal to or greater than the max. operating pressure of the spraying

equipment and any accessories.

The lowest value is to be taken for the complete system.

➤ Disconnect the heater from the power source.

➤ Ensure that the

Fluid Heater has been connected correctly

according to the instructions in chap. 3.3 Unit structure on page 19 and

that all fittings are tightened properly.

➤ Now complete all steps found in the spray equipment's Operation manual

covering pressure testing of the system.

5.3 Unit preparation

➤ Always remember that the Fluid Heater may only be flushed

when cold an disconnected from the electrical power supply.

➤ Always observe the working temperature given by the manufacturer of

the coating to be heated.

➤ Check to ensure that accessories (i.e.temperature gauges, back pressure

valves) are connected correctly.

➤ Check to ensure that the pressure ratings of all system components

and accessorires correspond to the maximum operating pressure of the

Fluid Heater.

➤ Check for the proper ground of:

– spray pump

– Fluid Heater

– accessories

– object to be coated

➤ Observe all instructions found in the Operation manual for the spray

pump and all accessories.

➤ When starting the unit and after any repairs, maintenance or cleaning
