WARNING
Electrical grounding is required
on all Steambath Generators.
Do not remove or change the
Generator's grounding unless
specifically directed to do so by
these instructions.

SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLATION.
SECTION 1: GENERAL INFORMATION
The Steam Generator is listed by ETL. The ETL listing will remain valid so long as the Option Kit is
installed per these instructions.
This ADT Option Kit upgrades a Generator to automatically flush and drain up to sixty (60) minutes
after the last use. It will leave the tank empty after the flush and drain cycle. A second ADT Option
is used for ganged generators.
SECTION 2: INSPECT EXISTING LOCATION
1. Count the total number of Generators at this site.
2. If there are two (2) or three (3) Generators this kit must be installed on all Generators.
3. If there is only one Generator proceed to Section 3A. If there are two (2) or three (3) Generators
skip ahead to Section 3B.
4211-113 07-25-11
All electrical supplies to
the Generator should be
disconnected before and during
the installation of this Option.
All wiring must be installed by a
licensed electrical contractor in
accordance with local and
national codes.
All plumbing must be installed
by a licensed plumber in
accordance with local
and national codes.
(an air gap or check valve
may be required)

WARNING
All plumbing shall be installed by a licensed plumbing contractor and conform to local and
national codes. (an air gap or check valve may be required)
MATERIAL (Locally available)
- 1/2 inch copper pipe for the tank drain
- Fittings for drain as required
- Pipe thread compound or teflon tape
All plumbing must be installed
by a licensed plumber
in accordance with local
and national codes.
(an air gap or check valve may
be required by local codes)
1. If the Option is being installed on an existing Generator, it will be necessary to remove
enough drain plumbing to install the motorized drain valve. See Diagrams 1, 2 & 3.
IMPORTANT
All Generator plumbing must be installed so that the valve motor may be
removed to clear the element service clearance area shown in Diagram 2.
2. Install the 3" nipple to the tank. Attach the motorized drain valve to the nipple. The drain
valve should be upright and level.
IMPORTANT
The ball valve does not have directional flow.
Do not tilt over 45 degrees. See Diagram 1.
Do Not drain the tank
into the steam room!
Boiling water may be discharged
from the drain. Draining the tank
into the Steam Room may
present a scald hazard and/or
damage materials used to
construct the Steam Room.
3. Run a 1/2" copper drain line from the motorized drain valve outlet to a gravity flow drain. Do not run the drain uphill. The drain must be
connected in accordance with local and national codes.
SECTION 3B: PLUMBING MULTIPLE GENERATORS
All plumbing shall be installed by a licensed plumbing contractor and conform to local and national codes.
(an air gap or check valve may be required)
MATERIAL (Locally available)
- 1/2 inch copper pipe for the tank drain
- Fittings for drain as required
- Pipe thread compound or teflon tape
IMPORTANT
Detailed drain connection information is in the Installation Instructions packed with the Steam Generators.
The instructions must be used to assure proper drain operation.
1. If this is an old installation being upgraded, it can require up to three (3) automatic drain valves, one per generator.
IMPORTANT
If additional drain valves or automatic drain valve kits are required, call the Technical Support Department at 1-800-363-0251.
2. Install all automatic drain valves. All valves should be installed as shown in Diagrams 1 thru 6.
IMPORTANT
All motorized drain valve outlets must be within six (6) feet and one (1) 90° bend of the site gravity drain.
Use pipe thread compound or teflon tape on all threaded fittings.
SECTION 4: MOUNTING THE DRAIN VALVE'S MOTOR
The drain valve is designed so its motor may
be easily removed to facilitate installation and
service. Before removing or installing the
motor, make sure the lever (used to manually
open the valve for service) is not latched
open. (See Diagram 7)
To remove the motor, turn it carefully to the
left until it stops then lift straight up to remove.
To reinstall the motor, carefully set the motor
onto the valve's shaft, set the motor down
onto its mounting posts, then turn the motor to
the right until it locks. (See Diagram 8)
If the motor is not properly secured in place,
the valve may leak or fail to open.

WARNING
SECTION 5: WIRING
All electrical supplies to
the Generator should be
disconnected before and during
installation of this Option.
1. The safety of this equipment requires that power and control wiring be segregated into the
areas shown in Diagram 9.
2. Route the drain valve wires through the conduit to a knock out near the steam outlet.
See Diagrams 10 & 11.
User Shock Hazard! 208-240V
wires attached to this Option
must be routed per these
instructions.
3. Route the wires into the TB2 drain terminal block on the PCA. See Diagram 11.
4. For multiple Generator installations check for other motorized drain valves in the system.
All drain valves connect to TB2 terminal block on the PCA's.
User Shock Hazard! If existing
wiring is disturbed assure that
the final installation conforms
with generator wiring diagram.
Conduit must be used when
installing drain valve to connect
the valve to ground.

SECTION 6: OPERATIONAL TEST
1. Assure power and water are on.
2. Turn on the Generator(s) using the owner's control. Allow the tank(s) to fill completely. Adjust the bath temperature to a point at least
10°F (6C) above the current steam room temperature to ensure the steamer begins heating the water.
3. Turn off the Generator(s) using the owner's control.
4. Sixty minutes (60) after the Generator is turned off, the drain will open and close a few times and water will be added to the generator
as needed to cool the water and drain the tank; this could take up to 15 minutes. Once the drain cycle is complete, the tank will remain
empty until the next bath. No water should come out the steam head.
The unit is now ready for operation.
SECTION 7: TROUBLESHOOTING GUIDE
There are no user serviceable parts in the Generator. All repair should be performed by a qualified service person. For additional assistance
or the factory authorized service person nearest you call Technical Support at 1-800-363-0251. The Troubleshooting Guide below is meant as
a general aid only. Follow ACTION TO BE TAKEN in order until the problem is resolved.
NOTE: The ADT Drain Valves are normally closed. They open only when engergized by the steam generator.
These valves are ball valves and are not directional.
SYMPTOMS
PROBABLE CAUSES
ACTION TO BE TAKEN
Drain Valve leaks
Motor not secured to the valve
or
Valve part way open
Remount motor per Section 4
or
Debris in valve
or
Faulty PCA (Circuit Board)
Water does not run
out of the drain.
Manual drain valve closed
or
Valve or drain piping plugged
or
Faulty Drain Valve
or
Faulty PCA (Circuit Board)
Water runs out steam
outlet during drain cycle.
Faulty PCA
Make sure the motor s manual lever is not latched open
or sticking aginst an obstruction.
Clean valve
Remove wires from PCA. If leak stops the PCA may be faulty.
If leak continues, check steps above.
Make sure any manual valves in the drain piping are open
Clean valve and piping
Make sure the motor s manual lever can move freely and is
moving when the valve should be opening. If it does not move,
check wiring. Call technical support at 1-800-363-0251.
If steamer is not operating, check the 1A fuse on the PCA.
Otherwise, contact Technical Support at 1-800-363-0251.
