CAREL humiSteam Lite

1.3 Plumbing
1.3.1 Water supply
The HumiSteam must be supplied with water (not softened)
having the following characteristics:
The water feed line should be ½” copper, PVC or poly tubing
run to within 3 feet of the humidifier, then bushed down to ¼”
O.D. copper or poly to make the final connection to the ¼”
O.D. compression fitting underneath the humidifier. With poly tubing an insert should be used to support the
tubing and prevent leaks. This insert is not provided.
