1.6 Unit in Storage
If a unit is going to be placed in storage for an extended period (more than 90 days), it is recommended that all rubber
components be replaced (o-rings, rear seal, expansion tank, etc.). Failure to replace rubber components could cause leaks
which may damange components.
When the dispenser is mounted onto a base cart, it must be secured with bolts as instructed in
Section 4.2. Use caution when moving the cart. Avoid surfaces that are not level and smooth
under the width of the casters to prevent tipping.
