Hobart DWT-AM15 Installation Manual

AM15 DISHWASHERS

DWT-AM15 DRAIN WATER TEMPERING KIT ML-130138-Z

This kit must be installed by a Hobart Service Technician. The drain water tempering kit reduces the temperature of drain water exiting an AM15 dishwasher by adding cold

water to the drain water. The drain water tempering kit valve opens as the AM15 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.

Installation

1. Remove front and side covers, and control door.

2. Install thermostat on component panel.

3. Route capillary tube through braided hose grommet.

NOTE: Use preferred type of pipe sealant on all threaded plumbing connections.

1. Screw 1-1/2" CPVC tee to drain. NOTE: Make sure tee is oriented so that it has easy

access to the cold water inlet and a floor drain. Do not face towards a leg or wall.

2. Attach brass adapter and nipple to CPVC tee.

Plumbing Connection

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.

3. Attach 1/2" union, backflow preventer, solenoid valve, and line strainer to the nipple.

NOTE: Line strainer and backflow preventer should face downward.

4. Attach 1-1/2" male adapter, 6" CPVC pipe, wye, and remaining 1-1/2" CPVC piping as needed to reach a drain.

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.

Remove any existing drain plumbing before installing drain water tempering kit.
