NOTICE
Using water outside the limits specified in this manual
without appropriate adjustment in the maintenance
schedule voids warranty coverage.
E. Water Connections for the MINI
1. Install Water Supply
a. Install the water supply before positioning the MINI.
b. Water supply line(s) must be designed so the MINI can be moved for service.
c. Construct all supply lines up to the point of installing the MINI.
d. Flush the water supply lines before connecting the MINI to the water supply lines.
e. Use of the supplied strainer is mandatory for warranty coverage. Use of a water filtration
system is recommended. Contact Cleveland Range at 216-481-4900 for details.
2. Water Supply Requirements
a. Water Quality
1) Check the quality of supply water (described below) before designing the water supply.
2) Contact a local water treatment specialist for on-premises water analysis.
3) Minimum feed water quality requirements are listed in Table 2-3.
4) Poor water supply quality degrades MINI performance.
5) Softened or chlorinated water damages the MINI by increasing corrosion. Carbon type
filters are required before water enters the MINI if supply water is softened or chlorinated.
6) If a water treatment system must be installed to achieve acceptable water quality, install it
BEFORE connecting the water supply lines to a MINI.
7) If analysis shows that supply water is below Minimum Water Quality:
EITHER a water treatment system and/or carbon filter must be installed in the line
feeding the spritzer,
OR the frequency of maintenance and cleaning must be increased beyond that
recommended in the maintenance schedule,
AND Contact your Cleveland Range sales representative for details on how to
provide water per Minimum Water Quality Requirements in Table 2-3, or how to
increase the frequency of maintenance and cleaning.
