TYPES OF MACHINES

Glasswashers – Various sized baskets and electrical supply needed depending in how many glasses needed to be cleaned in a given time.

Undercounter Dishwashers - Suitable for up to 70 covers (500mm basket) – depending on flow of the dirty crockery

Pass Through Dishwasher - Suitable for anywhere from 50 to 300 covers - depending on flow of the dirty crockery

Rack Conveyor Dishwasher - Suitable for 300 covers +

·         The difference between a glass and dishwasher is that the rinse temperature on a glasswasher is around 65ºC on a dishwasher its around 80ºC. The dishwasher will use more corrosive chemicals

·         Using glassware in a dishwasher over time will make the glasses become streaky due to the rinsing temperature. Using crockery in a glasswasher won’t always clean the item properly and not pass EHO regulations

·         Machines generally up to 400 x 400sq mm basket will run on a 13 amp (3 pin plug)

·         450 x 450 sq mm baskets and above are more suited to running off a wired electric supply, due to the larger wash tank and amount of water the element is more powerful to maintain a short heat up and recovery time.

APPROXIMATE HEAT UP TIMES

·         Cold Fill 13 amp – 50 minutes

·         Hot Fill 13 amp – 30 minutes

·         Cold Fill 30 Amp – 30 minutes

·         Hot Fill 30 Amp – 15 minutes

WASTE OUTLETS

Gravity waste is where the waste pipe must be lower than the machine as to allow the waste water to be solely drawn away via gravity. This application is used mostly in pubs as the waste water can be fed into the cellar.

Drain pump waste machines, the waste water can go either up or down from the waste outlet of the machine, although it is always good practice to put this waste pipe to a higher level than the waste outlet. The stand pipe on the pipe on the drain pump must be higher than then appliance.

BASKET SIZES

Glass and dishwashing units can come with different basket sizes. In regards to the glasswashers, generally these are supplied with an open basket. This meaning the inside of the basket is flat in order to stand the glasses up. Here is a list of the available basket sizes and the approximate capacity of ‘nonic’ pint glasses.

350mm x 350mm – 12 glasses

400mm x 400mm – 16 glasses

450mm x 450mm – 20 glasses

500mm x 500mm – 25 glasses

·         Open/cup basket – Flat inside the basket usually used for washing cups and glasses

·         Plate basket – Tend to be ‘spiked’ inside the basket in order to stand the plates upright when washing

·         Cutlery basket – Sectioned smaller baskets designed to stand in the open basket for cutlery

WATER SOFTENERS

·         In hard water areas we recommend the use of water filtration units to prevent limescale and all other impurities within the water

·         Units are not covered under warranty if the fault is found to be caused by limescale build up

ADDITIONAL OPTIONS

·         Automatic detergent & rinse aid dispensers – Pumps inside the machine enabling the correct draw of each chemical to be taken into the machine automatically per cycle.

·         Double skinned – Some units may have a ‘double skinned’ chassis or door. This will make the machine quieter in operation and more energy efficient.

·         Integrated water softener – Some machines have an in built water softener as opposed to a separate standalone manual water softener. This is useful where space is of a premium.
