Filling the condensate trap with water

DANGER

When initial start up, make sure that you perform the following procedures.

This is to prevent dangerous exhaust gases from entering the building.

Failure to following procedure could result in severe personal injury or death.

After installing the drain pipe, make sure that the area around the unit is well ventilated; open a window or a

door if necessary. Then, operate the unit and verify that condensate is coming out of the drain pipe. (During

normal use of the unit, condensate will begin to discharge from the drain pipe within 15 minutes of use.

However, depending on the season and/or installation site conditions, it may take longer.)
