GENERAL
The Rhima RO Mini Reverse Osmosis unit is the ideal companion to your Rhima High Sparkle dishwasher and together will provide you with an efficient, streak-free, polish-free system that will eliminate labour-intensive, hand polishing of glasses and cutlery. By reducing the TDS (Total Dissolved Solids) in the water supplied to the dishwasher to a negligible level, glasses, cutlery, and anything being washed will dry spot and streak free.

INSTALLATION OF THE REVERSE OSMOSIS EQUIPMENT

PRECAUTIONS

1. The installation of your Rhima RO Mini Reverse Osmosis unit must be carried out by a suitably qualified tradesperson.
2. The temperature of the water supplied to the RO unit must not exceed 38° Celsius to prevent reduction in performance and the life of the RO membrane.
3. The incoming water pressure must be between 100kPa – 400kPA to prevent malfunction or damage to the unit.
4. The unit must not be installed laying down or on an angle as the leak sensor may be activated.
5. The unit must not be installed next to a heat source, for example a refrigerator or hot water service.

INSTALLATION

1. The unit should be installed according to Fig. 1 below. The bypass allows the dishwasher to continue to operate if the RO unit needs to be removed for servicing or membrane/filter replacement.
   Note: Depending on the situation and local plumbing regulations, additional plumbing fittings may be required to those supplied.

2. This unit contains a Pre-Filter (CF), an RO Membrane (RO), and a Post-Filter (CB). If not already installed when received, the 3 filters must be installed according to the following instructions:

3. Remove the rubber plugs on the 3 filters according to Fig. 2 below:

4. Rinse the Pre-Filter (CF) under cold running water to remove any carbon dust that may block the RO Membrane (RO) when first turned on.

5. Install the RO Membrane (RO) into the upper position, the Post-Filter (CB) into the middle position and the Pre-Filter (CF) into the lower position.
   To install the filters, align the filter with the handle in a horizontal position, as shown in Fig. 3 below. Insert firmly and turn the handle 90 degrees clockwise to lock into position as shown inFig. 4 below. Ensure the watertightness of the filter seals before use.

MAINTENANCE

• The filters and RO Membrane in your Rhima RO Mini Reverse Osmosis unit are considered consumable items and as such, have a limited lifespan. The frequency of replacement will depend on the quality of the local water supply, and the frequency of usage. Extending the replacement intervals past those recommended will result in poor performance and wash results, and in some cases, the unit may breakdown entirely requiring service intervention to rectify.
• The Rhima RO Mini Reverse Osmosis unit has indicator lights on the front panel that change colour indicating the life remaining in the filters. Refer to Table 1 below:

Table 1: LIFETIME DISPLAY OF THE FILTERS

LIFESPAN| LIFE REMAINING (DAYS)| CAPACITY OF REMAINING LITRES| DISPLAY INDICATOR| ALARM
---|---|---|---|---
Normal.| > 15| > 150| Permanent blue.| No alarm.
There is little left.| 0 < X ≤ 15| 0 < Y ≤1 50| Permanent lilac.| Double beep when filter life is short.
Exhausted.| ≤ 0| ≤ 0| Permanent red.| Beeps when water is dispensed.

The recommended replacement intervals indicated below are a guide only, and as stated above, will depend on a number of specific local factors.

• Pre-Filter (CF) – Every 12 months minimum
• RO Membrane (RO) – 12-24 months
• Post-Filter (CB) – Every 12 months minimum

Replacement filters and membranes are available from Rhima spare parts department.
Note: The use of non-original spare parts, consumables, or improper installation may result in your warranty
