Chemical
•
This dishwasher is supplied with Detergent and Rinse Fluid injector pumps.
•
To connect to chemicals, insert pump inlet hose into container of commercial low foam
detergent and rinse fluid.
NOTE: Externally adjustable chemical pumps are fitted and pre-set at an average level,
these need to be calibrated on site according to the chemical being used and site specific
conditions such as the water quality and how the machine is being used. Failure to do so
may result in excessive dosing which can result in foaming and overflowing, or
insufficient dosing which can cause inferior wash results and impact components
through a build up of grease. If in doubt, contact your chemical company for assistance.
NOTE: Commercial detergents can be hazardous – read instructions, store safely and
handle with care. Care needs to be taken when changing chemicals, ensuring that the
detergent is not accidentally connected to the rinse fluid inlet line.
NOTE: If uncertain, please consult a chemical specialist for assistance in selecting the
right chemicals and calibrating machine settings to suit this along with your unique site
conditions and requirements.
Waste
•
Connect drain pump hose supplied to upstand or sink waste connection.
• With a standard trap the drain connection height will be about 580mm below the bench
height on the model (320mm above floor with door open height at 900mm).
NOTE: Either copper or PVC may be used for the waste connection – PVC is more
resistant to some harsh detergents. Some authorities suggest that copper is required
because the machine rinses at up to 90°C. It is important to note that rinse water mixes
with the 65°C wash water before discharge and then flows into the trap where the
water is further cooled before entering the drainage plumbing. We recommend
consulting your local authority to ensure your site remains compliant.
