BASIC HUMIDIFIER CONFIGURATION
NORTEC NHSC / NHDI humidifiers share a
modular sheet metal cabinet. Each unit has a right
side electrical compartment. Each electrical
compartment has a hinge-down front door which is
removable from any partially or fully opened position.
Each electrical compartment has a screw-mounted
right side cover which can open for ease of electrical
connection. For safety, the door when closed keeps
the side cover from being opened.
Single units have a plumbing compartment
attached to the left side of the electrical. Double units
have a second plumbing compartment. Each
plumbing compartment has a hinge-down front door.
For safety, the door must be closed in order to engage
the safety interlock. To avoid any danger, never
operate the humidifier with a door off.
To open the doors, unlock, lift door up slightly and
pull top of door forward. Door will hinge 180 degrees
and hang straight down. To remove door, swing door
parallel to floor. Then lift up slightly and out. To
reinstall door, hold parallel to floor and insert hinge
pins at bottom.
