Dissolve the Cleaning Agent with 2 or 3 Ltr of water then pour it into the Chiller Tank. Circulate the dampening solution for 1 hour.
Chiller tank does not need to be emptied first. Pour Cleaning Agent into the tank and mix with the dampening solution in the tank (water + existing fountain solution + IPA). Surfactants contained in the dampening solution are expected to create a synergistic effect. However, if the dampening solution is considered highly contaminated by ink residue or paper dust etc., use fresh water.
Allow the printing machine to run (power ON) to circulate the liquid in the chiller tank (which has been added with a cleaning agent) so that the solution can pass through the circulation pipe and clean the inside of the pipe and also inside the tank.
Use 1 pack (500 gr) of Cleaning Agent for every 100 Ltr Dampening Solution. If the chiller tank is smaller, for example 50 ltr capacity, just use 250gr of the Cleaning Agent.
Pour the Neutralizer and circulate the dampening solution for 15 to 30 minutes. The engine is running (power ON). After pouring the Cleaning Agent, the pH value of the solution must be 10-11 and with the Neutralizer added, the pH value must drop to 6.5 - 7.5 (sometimes bubbles will appear when the neutralizer is added and circulated, but it will disappear after a while).
The recommendation to use Neutralizer is 1 Ltr for each pack (500 gr) Cleaning Agent. And the usege of Neutralizer can be reduced for smaller size chiller tank.
Drain the dampening solution completely after the process of neutralization and circulation of the chiller tank with clean water for 15 to 30 minutes for rinsing. Let the engine run with power ON with fresh water.
How much clean water do we have to fill? Refill the chiller tank with water with the same amount or slightly more than usual when you fill the tank with a dampening solution.
