PRE-INSTALLATION CONSIDERATIONS
1.7 DIMENSIONS OF THE MACHINE
Figure 4
Dimensions for the installation.
1.8 REQUIRED INSTALLATION AREA
Make sure that from the operating position the user
can see all of the machine and the surrounding area.
The operator should prevent non authorized persons
and/or objects from entering the area which may create
potential hazards.
The machine should be installed on a stable level floor.
Do not install the machine on a uneven floor.
If the balancer is to be installed on a raised floor, the
floor must have a capacity of at least 110lbs per sq ft.
(5000 N/m² - 500 kg/m²).
It is not required to secure the machine to the floor.
Install the machine in a dry, covered area.
The installation of the machine requires a working area
of at least 60” x 48” (1524mm x 1219 mm) (Figure 5).
NOTE: Do not install the balancer below grade level
or in a pit.
Figure 5 - Recommended Work Area
1.9 INSTALLATION INSTRUCTIONS
