Drain test
Verify the integrity of the drain pipe. In cases of new construction, we recommend testing the drain
before cementing the ceiling.
Units with water pump
1. Remove the testing port cover and pour 2000ml of water in the drain pan.
2. Operate the unit in cooling mode. The operation of the pump will be heard during testing. Verify
that water drains correctly (1 minute delay, depending upon the length of the drain tube).
Confirm that all pipe fittings are leak-free.
3. Shut the unit down and replace the testing port cover.
