Electronic Equipment (WEEE). By ensuring that the product is scrapped correctly, you will help to
prevent potenal negave consequences for the environment and for health. This symbol indicates
that the product should not be treated as domesc waste but should be taken to a dedicated recycling
center for electrical and electronic equipment. Immediately prior to scrapping, cut o the power cable.
For more informaon on the treatment, recovery and recycling of this product, please contact
the appropriate local oce, the waste disposal service or the reseller from which the product was

Installaon and Maintenance Manual
Operang Environment
 Install the machine in a clean, dry, well-venlated room. It is designed to funcon correctly in environments
with a temperature of 16°C to 32°C – Climac Class N, (between 61°F and 90°F).
 Check that the water cooler is level, that it is on a surface that can support its weight and in an environment
suitable for its size and use.
 Do not place the machine near a source of heat.
 To guarantee adequate venlaon, leave at least 4" (100 mm) of space around the unit.
 Take care not to damage the cooling uid circuit. It is essenal to ensure that the tubes of the refrigerant
circuit are not damaged.
 The unit is not intended for use by children.
 Keep the areas surrounding the unit dry to avoid the risk of people slipping.
 The unit must not be cleaned with a water jet.
Water
 Always connect the water cooler to a water main that supplies drinking water only.
 Use of 3/8" diameter connecons for DSWH160UVPC is recommended.
 Turn o the main water inlet tap if the unit is not to be used for a long period.
Electrical
 Check that the voltage shown on the serial number plate corresponds to the voltage being
supplied at the installaon site.
 Do not use extension cables or mulple-power sockets. The machine must be located
close enough to a standard power socket that the supplied power cable reaches without
stretching.
 Aer installaon, check that the machine is not standing on its power supply cable.
 Ensure that it is possible to disconnect the power supply either by removing the plug or via a two-pole circuit
breaker placed upstream of the plug.
 Before any maintenance or cleaning operaon is carried out, remove the plug from the socket or disconnect
the power supply.
 If the power cable is damaged, it must be replaced by the manufacturer, by its technical support service or by
a qualied technician.
 Do not posion other electrical equipment in the immediate vicinity of the water cooler.

Roune Maintenance
Daily
 Clean all external surfaces of the machine, the drip tray and the dispensing nozzles.
NOTICE: It is recommended that all external components of the product be cleaned daily.
It is recommended that you use dish soap, warm water and a clean, so cloth to clean the product.
DO NOT USE THE FOLLOWING PRODUCTS:
Do not use ... chlorine bleach soluons on the product. Chlorides found in most soaps, detergents, bleaches and
cleaners can aack stainless steel. These products can cause surface-ping.
Do not use ... metal bers to clean the product. Metal bers have a tendency to disintegrate and release small
metal parcles that are embedded in the surface. Metal parcles oxidize and give the impression that the
surface of the product is rusng.
Do not use ... abrasive cleaners or abrasive pads, as these will scratch the surface of the product.
Do not use ... a water jet.
 To remove limescale, use a slightly acidic product (e.g. citric acid) that has been heavily diluted – excessive
acidity may damage the surface of the steel.
 To clean the drip tray, use a diluted limescale cleaner such as citric acid. The drip tray may also be washed in
the dishwasher.
 Before cleaning the keypad, turn o the machine to prevent accidentally dispensing water.
Weekly
 Use a vacuum to clean out all vents.

1000003740 (Rev. A - 02/2017)
Annually
 Replace the water lter aer 6000 gallons or a maximum of 1 year, or earlier depending on water quality.
NOTICE: The lter head has an internal shuto valve that stops the ow of water when the lter is
removed. It is not necessary to shut o the water supply.
1. Turn used lter counterclockwise (to the le) 1/4 turn to remove from lter head. Pull lter away from head
and remove.
2. Remove the cap from the new lter. Place the cap on the used lter to seal it.
3. Insert the new lter into the lter head and turn the lter clockwise (to the right) unl it stops.
4. Place a receptacle under the sll water dispenser and dispense connuously for a minimum of two gallons to
purge air and ne carbon parcles from lter.
 Sanize the machine
NOTICE: This operaon must be carried out by your ELKAY reseller or by a qualied technician.
When required
 Replace the UV lamp
CAUTION: The light emied by the ultra-violet lamp may cause serious burns to the eyes and skin.
Disconnect the electrical source of supply of the UV radiaon before opening the machine.
NOTICE: The UV OUT lamp can not be installed on the hot water nozzle.
1. Disconnect the unit from its electrical source.
2. Once the unit is shut down, open the side panel with the key provided in the kit.
3. Disconnect the electrical connector of the UV OUT lamp. Pull the lamp removing it from its ng holder —
handling it carefully.
4. Insert the new lamp and reconnect the connector — handling it carefully.
5. Repeat the procedure for all the dispensing valves.
6. The used UV lamps can be disposed at your local waste management site.
