DRAIN CONNECTIONS
ASKO provides a 7/8” (22 mm) corregated drain hose which is connected to the back of the unit to form a high loop. If additional drain hose is the added hose and any joints or connections can be no smaller than 7/8" O.D. Stock.
NOTE:Do not use any fittings anywhere in the drain line that are less than 7/8" (22 mm) O.D. Stock.
.
The access hole for the drain line should be
The end of the drain line is 1/2” (12 mm), but it is adjustable to 7/8”, 3/4”, 5/ 8” (22mm, 19 mm, and 16
mm). If the drain connection is larger than 1/2” (12 mm), you can easily cut the drain line to fit the connection.
The illustrations to the right show three ways to connect the drain supply line.
THE HIGH LOOP
The high loop is necessary for proper draining. Therefore, all ASKO dishwashers have the drain hoses attached to the drain pump and
fastened to the top back of the unit, as illustrated. This gives the drain hose an automatic high loop, which is necessary for proper draining. The drain hose is fastened at the best high loop height.
To eliminate potential drain problems, simply leave this hose in place.
IMPORTANT THINGS TO REMEMBER:
♦Failure to provide the proper drain connection height (minimum of 20" (508 mm) above the bottom of the dishwasher base) or a 20" (508 mm) high loop will result in improper drainage, which will damage the machine.
♦No part of the drain hose should be higher than 35" (889 mm) from the bottom of the dishwasher.
♦The drain hose can be extended to a maximum length of 10 feet (3048 mm). Joints and jointed tubes, if any, must have a minimum 7/8" (22 mm) O.D. Stock.
♦If the drain line is going to be connected to a waste disposer, be sure to remove the knockout or plug from the fitting on the disposer before connecting the drain line.
♦Do not use fittings smaller than 7/8” (22 mm); otherwise the water may not drain properly.
When the installation is ready, open the supply valve and let the pressure act for a while. Then check that all connections are tight and there are no leaks.
