HEALTH AND SAFETY

For the servicing of refrigeration products, containing Isobutane R600a refrigerant.

These instructions are in addition to any other Company procedures already published.

Published primarily for Indesit Company engineers working in the UK or Southern Ireland, for

which these instructions are MANDATORY.

1. Only engineers who have been trained on the safe handling of Isobutane R600a refrigerant are

authorised to transport, store or carry out system repairs.

2. This manual is not intended as a comprehensive repair/maintenance guide to the appliance.

3. Must only be used by suitably qualified persons having technical competence, applicable product

knowledge, suitable tools and test equipment.

4. Servicing of electrical appliances must be undertaken with the appliance disconnected (unplugged

from the electrical supply).

5. Servicing must be preceded by earth continuity and insulation checks, plus refrigerant leak

detection.

6. Personal safety precautions must be taken to protect against accidents caused by sharp edges on

metal and plastic parts.

7. After servicing, the appliance must be rechecked for electrical safety.

8. Smoking, naked flames, or operating gas and/or electrical equipment (including cordless power

tools) are forbidden within the storage area, working area and vehicles used to transport Isobutane.

9. The carrying case for the scales and refrigerant must display a red flammability label

Part Number C00247960 (8100063) that should be visible and readable at all times.

10. The vehicle and storage area must be ventilated as far as is reasonably practicable and the

aluminium case kept out of direct sunlight. The storage temperature of Isobutane should not exceed

50°C.

11. The vehicle transporting Isobutane (R600a) refrigerant must display a Red Flammable Gas warning

sticker (Part No. C00247960 [(8100063)].

12. Engineers should not wear clothes that are liable to cause static discharge ('electrostatic sparking').

13. Avoid working in small rooms.

14. Do not work in cellars.

15. Whenever possible move the appliance into a larger open area away from possible ignition sources.

16. Request the customer to turn off all other electrical and gas appliances in the near vicinity of the

repair and note that it is done. Customers should be advised to restrict activity within the near vicinity

for a short time.

17. Isobutane refrigerant must be vented to atmosphere, (outside of the premises e.g. via open window

through the clear plastic hose supplied).

18. Isobutane is heavier than air and must not be vented within 3 metres of the following: sewer cover,

cellar, drain or any similar construction lower than ground level, boiler air inlet/outlet, or near any

possible source of ignition.

HEALTH AND SAFETY

19. Working with a naked flame i.e. soldering or brazing is forbidden. Unless otherwise stated,

pipework connections must only be made using the Lokring coupling system.

20. Electronic leak detectors with high voltage tips must NOT be used with any Isobutane (R600a).

21. All equipment used for this activity must be checked regularly and maintained in a safe working

condition; parts must be replaced as required.

Information Regarding Isobutane Canisters

1. The maximum quantity of Isobutane an engineer should hold or store at any one time is two 1kg

net aluminium canisters, supplied individually as Part No. C00218421 (2602600).

2. Canisters must be stored inside the aluminium case with the weighing scales for protection from

possible damage and heat. The aluminium case must NEVER be placed next to a heat source or

in direct sunlight.

3. Isobutane must only be dispensed to the appliance from the 1kg net aluminium canister placed in

an upright position on the weighing scales provided.

4. All used canisters must be a returned as scrap and therefore, left out for the driver to collect and

return for disposal.

5. Canisters must not be punctured or the internal valve damaged.

6. Before storing the canister it must have the extraction tap valve removed and the internal valve of

the canister checked for leakage using leak detector (Leak Detector: Part No. C00222861

(5700043).

7. All used canisters and those found to be leaking should be exhausted to atmosphere to ensure

they are emptied completely. Refer to the following paragraph.

8. Refit the extraction tap if necessary, open the tap and then invert the canister.

This must be done outside in open air away from buildings and ignition sources and complying with

Item 18 on previous page.

INTRODUCTION

These models are built-in 70/30 split static two door fridge freezers. The freezer section is 4 Star rated.

The HM31AAE model uses Active Oxygen Technology.

The HM31AAE production commenced during July 2012.

The KM31AAE was introduced in August 2012.

The interior of the fridge has three safely glass shelves, one salad crisper and one chiller drawer.

The door has a large door shelf for bottles and two removable commodity racks. The freezer has two

drawer compartments, a freezer flap and one ice tray slotted in the freezer drawer.

The user controls and display are electronic.

The control system is fan air 2012.

The climate class rating is SN/ST/T, signifying that it is designed to operate in ambient temperatures

between +10°C to +43°C.

As with many refrigeration appliances, it is important that it is installed and operated within the

recommended ambient temperature range and that there is also adequate ventilation.

DOOR REVERSAL

NOTE: The doors ARE reversible.

ANTI-BACTERIA (Hygiene Control)

All models have built in anti-bacterial protection for life. Food safety is becoming increasingly important

to consumers with more and more cases of food poisoning. Hygiene control is built into the plastic of

the fridge interior during manufacturing so it cannot wash or wear out. It provides permanent protection

against bacteria as it reduces, on contact, the spread of food poisoning bacteria, which can cause

contamination and odour. It gives extra hygiene reassurance as it kills or inhibits the growth of any

bacteria, which may come into contact with the interior surfaces of the fridge. Hygiene control is

approved safe for use in food contact applications by the European Scientific Committee for Food and

has proven safe over many in personal care and household cleaning products.

DESCRIPTION OF THE APPLIANCE

Energy Saving Function

The Energy Saving function can be activated to optimise energy consumption while maintaining the

cooling performance of the product. This function maximises the amount of energy saved. Under these

conditions, the display remains off even when the door is opened.

The function is activated by pressing and holding the super freezer and FRZ (+) buttons simultaneously

for at least 6 seconds. Once the function has been activated, all LEDs will light up for 2 seconds to confirm

activation, and the temperature setting of +5, -18 will appear on the display. The display switches off after

5 seconds. To change the temperature, simply press the + and – buttons until you have reached the

desired temperature.

However, the Energy Saving function can also be disabled by switching the product off using the ON/OFF

button. When it is switched back on, the Energy Saving will be disabled.

In humid environments, when the Energy Saving function is enabled, slight condensation may form on

the appliance door; normal operating conditions are restored when the function is disabled.
