Adjusting Level of Unit

(1) Use a level to verify that the unit base is perfectly level with the floor. There should be no degree of
slope present.
(2) The unit should be installed so that the rear side of the unit is slightly (0 to 3/16 inch (0 to 5mm)) lower
than the front side, to allow and promote drainage discharge.
(3) Tighten the bolts of the suspension nuts with the suspension brackets after adjustment is completed.
Special plastic paint must be applied to the bolts in order to prevent them from loosening.
NOTE:
During position the installation process, keep the unit well covered with vinyl cover and related
components covered until it is time to hoist into position.
