Dacor DDW24S Installation Instruction

Grounding Instructions for a 

Permanently Connected Appliance

This unit must be grounded to operate properly. It 

must be connected to a grounded metal, permanent 

wiring system, or an equipment-grounding conductor 

must be run with the circuit conductors and 

connected to the equipment grounding terminal or 

lead of the appliance.
Damage to the dishwasher could occur if it is not 

properly grounded.
A three conductor electrical cable or conduit meeting 

local codes and ordinances is required. A UL listed 

strain relief is required if non-metalic cable is used. 

Suggested color coding: black, white and green.

Circuit Requirements

The wiring from the electrical outlet or junction box 

shall be connected to a circuit protected by a 15 

Amp. circuit breaker or time delay fuse, installed by a 

licensed electrician.

Water Supply Specifications

In order to prevent heat damage, all solder 

connections for the water line connected to the 

water supply valve must be made before the 

dishwasher water supply line is connected.

•  The dishwasher can be connected to a cold or 

hot water supply (maximum 160°F, 70°C). Dacor 

recommends using a hot water supply of 120°F 

(49°C) to 140°F (60°C). If a cold water supply is 

used, the washing times will be longer, but the 

performance will not be affected.

•  The water supply pressure must be between 4.2 

and 140 psi (30 - 1000 kPa). The water supply 

line and the shut-off valve must supply a flow 

volume of at least 3 gallons (12 liters) per minute. 

•  Install a 3/8” water supply valve for connection to 

the dishwasher’s water supply line in a location 

where it is easily accessible after the dishwasher 

is installed. 

•  The dishwasher water supply line is equipped 

with a 3/8” (1.0 cm) NPT female compression 

fitting on the end.

Grounding Instructions for a Cord-

Connected Appliance

This appliance must be grounded. In the event of 

a malfunction or breakdown, grounding will reduce 

the risk of electric shock by providing a path of least 

resistance for electric current. This appliance is 

equipped with a cord having an equipment-grounding 

conductor and a grounding plug. The plug must be 

plugged into an appropriate outlet that is installed 

and grounded in accordance with all local codes and 

ordinances.

•  Improper connection of the equipment-

grounding conductor can result in a risk 

of electric shock. Check with a qualified 

electrician or service representative if you are 

in doubt whether the appliance is properly 

grounded. Do not modify the plug provided with 

the appliance, if it will not fit the outlet, have a 

proper outlet installed by a qualified electrician.

•  Do not use an extension cord with this 

appliance.

Observe all governing codes and ordinances during 

planning and installation. Contact your local building 

department for further information.
