corresponds with humidifier voltage and phase
as indicated on humidifier’s nameplate label
(see Figure #1).

BASIC HUMIDIFIER CONFIGURATION

Liebert humidifier model SGH 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 also be removed for ease of electrical
connection. For safety, the door when closed keeps
the side cover from being removed.

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
which is not intended to be removed. For safety, the
door must be closed in order to engage the lock. To
avoid any danger, never operate the humidifier with a
door off. For safety, each door when closed engages
its own safety interlock switch. All switches must be
engaged before the unit will operate.

To open the doors, unlock key, 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. The door can then be closed.
