LX/LXi, LXG/LXiG, AND SR24H DISHWASHERS DWT2 DRAIN WATER TEMPERING KIT ML-130137
All kits must be installed by a Hobart Service Technician.
The Drain Water Tempering Kit reduces the temperature of drain water exiting an LX/LXi, LXG/LXiG, and SR24H dishwashers by adding cold water to the drain water. The Drain Water Tempering Kit valve opens as the LX/LXi, LXG/LXiG, and SR24H dishwasher drains and automatically adds cold water to the drain water.
NOTE: To make this a successful installation, the cold water line (45° F to 70° F [ 7° C to 21° C ] ) must be within 3' of the rear of the dishwasher. Recommended water service rough in is 1/2" trade size pipe (minimal) with shutoff valve and 1/2" MPT connection.
Immediately after unpacking, check for possible shipping damage. If damage is found, save packing material and contact the carrier within 15 days of delivery.

ELECTRICAL POWER TO THE
MACHINE AND FOLLOW LOCKOUT /
TAGOUT PROCEDURES.
1.Remove unit from wall to provide access to components.
2.Remove Base Cover from front of unit per Fig 1.
3.Remove Service Cover, Wire Way and Motor Cover from rear of unit per Fig 2.
NOTE: This kit is for all LX/ LXi and LXG/LXiG dishwashers. Machines with serial numbers between 23-1083-999 and 23-1084-003 and starting with serial number 23-1085-462 and higher have a drain pump. Machines with lower serial numbers utilize a drain solenoid valve. Identify machine type and select correct wiring harness from kit.
NOTE: For drain pump machines use harness 919275. For solenoid machines use wiring harness 919276.

Plumbing Connection
WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY AND PLUMBING CODES.
The plumber who connects this machine is responsible for making certain the water lines are thoroughly flushed out before connecting to any manual valve or solenoid valve. This "flush-out" is necessary to remove all foreign matter such as: chips (resulting from cutting or threading of pipes), pipe joint compound from the lines, or if soldered fittings are used, bits of solder or cuttings from the tubing.
Debris, if not removed, may lodge in the valves and render them inoperative. Manual valves or solenoid valves fouled by foreign matter and any expenses resulting from this fouling are NOT the responsibility of the manufacturer.
NOTE: Use preferred type of pipe sealant on all threaded plumbing connections.
1.Assemble drain tempering plumbing to the cold water line per Fig 5. Connect cold water (45° F to 70° F [7° C to 21° C]) to the 1/2" NPT union fitting.
2.Assemble drain tempering plumbing to the end of the LX/LXG Dishwasher drain hose per Fig 6.
Electrical Connections
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND / OR OTHER LOCAL ELECTRICAL CODES.
WARNING: DISCONNECT THE
ELECTRICAL POWER TO THE MACHINE AND FOLLOW LOCKOUT / TAGOUT PROCEDURES.
NOTE: Machines ranging in serial number between 23-1083-999 and 23-1084-003 and starting with Serial No. 23-1085-462 and higher have a drain pump. Machines with lower serial numbers utilize a drain solenoid valve. Identify machine and select correct wiring harness.
NOTE: Both wiring harnesses are in kit. (919275 Pump Drain and 919276 Solenoid Drain)
1.Identify drain system electrical connector and unplug it.
