Main features

• Built in hot water booster (top mounted in wash/rinse section).

• Water booster temperature rise can be set on site during the installation of the
machine. 40 °F rise (140 °F incoming water temperature), 70 °F rise (110 °F
incoming water temperature) or
100 °F rise (80 °F incoming water temperature).

• Atmospheric booster system with air break.

• Built in rinse booster pump guarantees constant rinse pressure.

• Speed of conveyor can be set through the control panel by the operator.
130 racks/hr or 200 racks/hr.

• Large counter balanced inspection doors in pre wash and wash/rinse sections
allow unrestricted all round access to the wash and rinse area. Door is insulated
with injected foam. This adds strength as well as reduces noise and heat loss.

• Large filters sloping towards the front to the smaller pressed filter box for quick
removal. Filters feature holes smaller than the concave ant-block wash nozzles so
large food cannot enter and block the wash system. Filters easy to remove from
pre wash as well as wash/rinse sections.

• Adjustable feet for full access underneath the machine for cleaning.

• Push button self cleaning cycle of the wash and rinse zones for ease of “end of
day” cleaning.

• Wash chamber without internal pipes and therefore no hidden dirt traps.

• Pre wash chamber without internal pipes and therefore no hidden
dirt traps.

• Self draining wash pumps provide maximum hygiene with no smells and all
wash and rinse zones drain automatically at the push of a button.

• Powerful 0.5 HP pre-wash pump.

• Powerful 2 HP wash pump.

• Heavy duty stainless steel wash pump (impeller and housing).

• Pre wash section uses cold water so food remains are not “baked” onto the
plates.

• Deep drawn pressed 26 gal wash tank with fully rounded corners, sloped
towards the drain to prevent dirt build up provides fast drainage in only a few
minutes. Pressed wash tank with no welded points offer a guaranteed water
tight solution.

• Deep drawn pressed 11.8 gal pre wash tank with fully rounded corners.

• Dishwasher structure is held together with a solid 2″ × 2″ stainless steel tube
sub-frame to provide long term sturdiness.

• All main components made in heavy duty anti-corrosive 304 type stainless steel:
tanks, panels, pre wash, wash & rinse arms and caps, doors, front, handle, rear
and side-panels and rack transportation system.

• Pre wash, wash and rinse arms can be easily removed for cleaning.

• IPX5 (NEMA4) water protection ensures no damage from cleaning.

• Autostart/stop ensures that the machine runs only when a rack is passing
through it. This reduces both water and energy consumption.

• Internal curtains made of silastic material and are not affected by detergent or
heat.

• Electronic control panel features large display for reading of wash and rinse
temperatures.

• Low water consumption. At 200 racks per hour, the machine uses only
83 gal/hr (0.4 gal/rack).

• Machine predisposed for external detergent and rinse aid connections.

Included Accessories

• Vent cowls (left and right side).

• One open sided dishwasher rack for trays.

• Rack for cups.

• Rack for dinner plates.
