2. CHECKS BEFORE OPERATION
WARNING
1.
To prevent
possible water leak, electric shock or fire, the installation must be
carried out by qualified personnel.
2. To use a gas water heater, thoroughly read its instruction manual. Ensure
adequate air intake and exhaust systems and exhaust hoods in accordance
with applicable laws for the type and capacity of the heater to prevent
dangerous conditions due to lack of oxygen and toxic gas generation.
[a] CHECKS AFTER INSTALLATION
* In the presence of the installer, check for proper installation according to the installation
manual provided.
* Receive the installation manual from the installer, and keep it for later reference.
[b] WATER REQUIREMENTS
* Proper water quality can improve warewashing performance by reducing spotting,
lowering chemical supply costs, improving productivity and extending equipment life.
Local water conditions vary. The recommended proper water treatment for effective and
efficient use of this equipment will also vary depending on the local water conditions. Ask
your municipal water supplier for details about local water specifics prior to installation.
* Recommended water hardness is not more than 100 mg/L. Water hardness above
100 mg/L should be treated by a water softener or in-line treatment. Water treatment
has been shown to reduce costs associated with machine cleaning, reduce the need
for deliming the dishwasher, reduce detergent usage and reduce corrosion of metallic
surfaces in the internal booster tank and dishwasher. Failures resulted from use of water
outside the required water conditions are not covered by warranty.
* Sediment, silica, chlorides or other dissolved solids may lead to a recommendation for
particulate filtration or reverse osmosis treatment.
* If an inspection of the dishwasher or internal booster tank reveals lime build-up after
the equipment has been in service, in-line water treatment should be considered, and,
if recommended, should be installed and used as directed. Contact an authorized
Hoshizaki service company for specific recommendations.
