Tighten the bolts securely using a double nut to prevent the bolts from becoming loose.
• If the bolts are not tightened securely, the unit will vibrate and an accident may occur.
• Tighten the bolts so that they can bear the weight of the unit.
3
Confirm that the unit is installed level.
• Confirm that the unit is installed level or is inclined within 1°(downward) against the drain outlet using a spirit
level.
• Do not set the unit inclined (upward) against the drain outlet; otherwise, water will leak from the unit.
