IMPORTANT: Ifbare chipboard is adjacent to or above the Washer door opening, seal with suitable paint to prevent swelling.

NOTE: Ensure floor and cupboard opening levels are the same to enable easy removal of the Washer for service requirements.

Cu·pboard opening dimensions.

Cui ouls for hoses and electrical cables on

All dimomions oro in miJlimolros.

Power

Supply

The power point must be in an accessible location adjacent to and not behind the

Washer.

The supply must be 240 Volt, 50 HZ with 15 Amp rating. The power point must be correctly earthed, if in doubt, have it checked by a qualified electrician. Before any work is carried out, the unit must be isolated from the power supply.

Water Supply

The hot water temperature must be 60 degrees C minimum.

Taps for the hot and cold water with 3/4" BSP connection must be provided

in

an accessible location adjacent to and not behind the Washer.

It is essential to use gate valves or ball valves, which have no non-return characteristics. DO NOT use stop taps.

The temperature of the hot water must not exceed 75 degrees C, adjust the hot water service setting if adjustable. The water supply for the Washer must be between 30 kPa and 1100 kPa. If the pressure exceeds 1100 kPa it will be necessary to fit a pressure limiting valve in the supply to the unit.

Water Hammer

Quick action taps and fast acting electric valves can cause water hammer.

This can result in very high pressures which could lead to failure ofthe pressure limiting valve or the electric water valves to the Washer. Water hammer can be prevented by fitting a flow control valve in line with and close to the quick action taps which cause the hammer.

Recommended type is R.M.C. MP 50 10-12 litres.

PERIODIC MAINTENANCE

Cleaning the inlet water filters

The special filter washer, between the tap and hose, filters all incoming water. To clean this, first close the shut off valve, than to release any water pressure left in the hose, select and start the program. Allow the machine to run for about 25 to 30 seconds, then switch off at the power point.

Unscrew the hose connection and gently remove the filter washer and rinse clean.

Refit the washer and hose to the shut off valve in the reverse order, take care not to over tighten.

The condition of the water supply hoses should be checked periodically.

IMPORTANT: Do not use iron and non-rust proof steel utensils in the Utensil Washer, and do not use soap impregnated steel pads for cleaning as this will cause rust stains on the stainless steel interior.

When not in use for long periods

To prevent any chance of odour:

• Ensure racks are completely cleared of utensils.

• Clean filters thoroughly. Ensure rubber door seal is clean, also the door liner edges, which are not cleaned by the wash cycle.

• Turn off the electricity and water.

• Leave the door ajar to avoid stuffiness.

This may be due to water loss caused by syphoning.

The machine will stay in the heating mode.

Check height of discharge end of drain hose, this should not be lower than 600mm from the top of the Utensil Washer.

Water does not empty out of machine.

Check drain hose for kinks and sharp bends.

Check drain filter for blockage.

If the machine pumps water into a bucket when the drainhose is disconnected from the waste pipe, then the waste pipe plumbing is blocked.

Machine Displays Fault Flashing on Control Panel

The machine is programmed to indicate ''fault'' on the Control Panel LED when the programme time has exceeded 45 minutes, this may be due to the hot inlet water being to cold:

• Check temperature of hot water to machine it should be 60°C

min.

• Even with the fault LED flashing, on account ofto Iowa water temperature the machine will complete the disinfecting programme satisfactorily.

IMPORTANT: It is essential that the discharge end of the drain hose terminates not lower than

600mm from the top of the Utensil Washer.

TROUBLE SHOOTING GUIDE

1. Poor Wash

Most poor wash problems are caused by insufficient water supply to the spray arms.

Clear any obstruction from the spray arms. Check cleanliness of the wash filters.

Check the upper spray arm nozzle for any blockage. Top spray arms only have jet holes on the top and a small drain hole on the underside.

Use a clear glass or plastic panel the size of the door opening to allow a clear view of the spray arms in operation.

Check top basket venturi cone lines up with delivery nozzle in top of tub.

BOTTOM SPRAY

ARIv1, jets should easily reach top of the liner, with substantial force when empty.

TOP SPRAY ARM. during this test cover bottom basket area with heavy dishes or pans. Jets from top spray arm should easily and forcefully reach the top of the liner.

If spray height is correct, check rotation of spray arms, the range is 20-36

RP.M.

Spray patterns should be clearly defined streams of water. (Not diffused. This indicates obstruction in spinner arm.

2. Bottom Spray Arm

(poor performance and/or low pressure)

Check water level in the Utensil Washer. Low water level will cause poor wash performance and pulsinglhunting of spray arm pressure. Allow machine to fill three times and check each fill. Compare water level in tub with min.max. marking on lower spray arm support, (see sketch) if water level is not correct refer to pressure switch adjustment. Low water level may be due to syphoning. Check drain hose routing.

not require to be dismantled. However, if there is a need to dismantle the Drain Pump after having removed it then follow this procedure:­

Removal of the Drain Pump cover/inlet spigot will require a ''Torx'' hand driver fitted with a T-15 drive to remove three torx headed screws which retain the pump cover/inlet spigot to the pump body/motor assembly. Prior to removing the three torx screws, view the

Drain Pump from the motor end with the two electrical tap terminals marked from left to right as

<eN'

& ''L'' and also inverted. The pump cover outlet spigot (three deep grooves on surface) is positioned in relation to the electrical terminals '"N" & ''L'' at an eleven o'clock position. Mark both pump cover and pump body to retain this relationship.

Remove the three torx headed screws and separate the pump cover from the pump body.

A Neoprene "0" ring is located within a groove on the pump housing, carefully remov~ the "0" ring, clean the groove and refit the "0" ring.

A flap valve is incorporated within the pump cover/inlet spigot. The purpose of the flap valve is to ensure water from the household drain system will not flow back into the dishwasher. Located within the end groove on the pump cover/outlet spigot is the retaining ring/flap valve. Lift the retaining ring/flap valve from the groove, clean, examine for damage and refit to pump cover/outlet spigot groove.

Establish that the domed surface of the flap valve is towards the seat face of the pump cover/outlet spigot. The retaining ring of the flap valve should be positioned within the groove, for the domed surface of the flap valve to contact the seat face effectively and be concentric with the bore of the pump cover/outlet spigot.

NOTE: If the flap valve is not seated correctly it will not operate as a non-return valve.

Refit the pump cover to the pump body, locating the outlet spigot at the eleven o'clock position in relation to the electrical terminals

''N &

L". Press both components together without damaging the neoprene "0" ring and fit the three torx head screws and tighten evenly.

Insert finger into pump coverrmlet spigot, engage with the impellor blade and establish impellor

will

turn freely.

NOTE: A magnetic effect between rotor and stator will cause the impellor to ''flick'' past the poles of the motor every

180

0

of rotation. This is normal and the effect is used to obtain a self clearing pump action.

Refer to refit section ofthe Drain Pump.

REMOVAL OF PARTS

DRAIN PUMP - REFIT TO MACHINE

Disconnect electrical power supply

It is recommended to replace the neoprene «0" ring which seals the pump coverfmlet spigot to the sump socket. Fit neoprene, ''0'' ring onto pump coverrmlet spigot and locate against the eight stops moulded onto the surface of the inlet spigot.

When engaging the drain pump inlet spigot to the sump socket, it is advised to smear water onto the surface of the neoprene

''0''

ring, to assist entry into the sump socket.

Approximately position the pump cover/outlet spigot towards the front of the machine, or in a horizontal mode, insert the pump cover/inlet spigot into the sump socket.

Exert hand pressure against the drain pump to compress the neoprene «0" ring and rotate at the same time approximately 90°, to seat the slotted locking plate of the Drain Pump against the retaining boss of the Sump.

Refit the Phillips flange head (two start thread) screw. Do not over-tighten.

Slide the double coil hose clamp over the drain hose elbow and fit the elbow over the pump cover/outlet spigot. Engage the two offset slots in the end of the drain hose elbow with the two lugs on the pump cover/outlet spigot.

Push the drain hose elbow finnly onto the two offset slots and lugs.

Compress the double coil hose clamp with multigrips/pliers and position clamp on drain hose elbow between the wash motor/pump and Drain Pump. This position allows access to refit or remove the double coil hose clamp with multigrips/pliers.

Refit the QC Terminals and wires to the Drain Pump tabs marked «N" &

'1..,".

Reassemble in reverse order.

Operate & test machine before leaving.

SONEX

HOSPITAL AND LABORATORY EQUIPMENT DETERGENT

SQNEX is a highly active liquid detergent free of colour and odour. It is specifically designed for manual and macbine cleanmg of anaesthetic equipment, instnunents, plastic and glass utensils in hospitals, pathology and research laboratories.

SONEX is moderately alkaline, non flammable and completely safe for use when used in accordance with

!he directions. It is non corrosive at use dilution.

In formulating SONEX particular care was taken to ensure rapid and complete riosibility so that cleaned arti­ cles are free of detergent residues. This is particularly important whenever resean:h is being conducted and articles such as micro titre dishes must be completely detergent free after final rinsing. It is equally important that all medical instroments be completely free of detergent residues.
