Downwind from the shelter the heater is connected to as well as other surrounding shelters that
stack from being blown back into the shelter(s).
Hardstand or other improved areas; however, any area that is level, free of large holes, trees,
debris; properly drained in event of bad weather, and within the guidelines of the Unit Standard
Operating Procedure (SOP) is acceptable.
The LCFH is designed to be used with any shelter equipped with duct tunnels that are 16 inches in
BEFORE OPERATION PMCS
Perform the "Before Operation PMCS" on all LCFH system components as outlined in WP 0010 00, prior
to preparing the heater for use. All scheduled maintenance must be performed on the heater and its
associated equipment prior to use.
POSITIONING THE HEATER OUTSIDE THE SHELTER
To prepare the LCFH for use, position the heater within 12 feet of the duct tunnels of the shelter using a
forklift rated to lift at least 625 pounds.
In order to move the LCFH into the proper position, the side wheels must be deployed and the front wheel
lowered to permit local mobility.
The LCFH may be safely operated in a wheels deployed (down) condition or with the
LCFH resting on its underside skids. The decision to operate with wheels deployed
versus on skids is dictated by conditions in the field of deployment.
Lowering the side wheels. Before the LCFH can be transported, or to permit local mobility, the side
wheels must be lowered and locked into position.
Lower the front wheel (1) by rotating the wheel jack handle (2) clockwise until the front wheel (1) contacts
the ground and begins to tilt the heater back on its snow skids. Continue until the front wheel is
Remove the locking pin (3) and remove wheel and axle assembly (4).
Rotate the wheel and axle assembly (4) 90 degrees.
Reinstall wheel and axle assembly (4) and engage locking pin (3).
Repeat for the opposite wheel.
Raise the front wheel (1) by rotating the wheel jack handle (2) counterclockwise until the top of the heater
cabinet is parallel to the ground. Ensure that the front wheel is positioned to permit free movement of the
caster (5) or the front wheel will not swivel properly.
