INSTALLATION INSTRUCTION SHEET
Summary
The 259BAC Drain Master is designed to feed chemicals into drains and grease traps to break up
grease, detergent build up and eliminate odors. All programming is done by use of a set of DIP
switches that determine the various times and amount of chemical to be dispensed.
Please read all instructions before proceeding with Drain Master installation.
Survey Location
Determine a location to hang the Drain Master on a wall near the drain or grease trap to be supplied
with the chemical product. The Drain Master can be hung on the wall by use of the supplied wall
bracket kit. The location should provide access to 120V, 208, 230/240V 50/60Hz electrical power.
Electrical Hookup:
All installations must be in accordance with city, county, state or provincial electrical codes and
be performed by a certified electrician. For questions, please contact local licensed electrical
contractor.
1. BEFORE GOING ANY FURTHER, AL L ELECT RICAL POWER MUST BE TURNED
OFF TO THE CIRCUIT THAT IS TO BE USED FOR THIS INSTALLATION.
LOCKOUT AND TAG PROCEDURES SHOULD BE OBSERVED WHEN
INSTALLING THIS DEVICE. NEVER OPEN THE DRAIN MASTER UNLESS
POWER HAS BEEN TURNED OFF. ONLY USE ELECTRICAL CODE APPROVED
INSULATED WIRING AND ELECTRICAL FIXTURES WITH THIS INSTALLATION.
2. Connect the power to t he Drain Master. The Dra in Master will accept 120V AC, 208VAC
or 230/240VAC 50/60Hz.
3. Locate the power terminal block inside the Drain Master enclosure. Connect the “return
line” to the appropriate terminal block position based on supply voltage. The black
“common” wire goes to “line”. The “earth gro und” wire must be connected to the terminal
block position labeled “GND”. The power line should be secured by use of a proper
electrical fitting thro ugh an access hole in the Drain Mast er enclosure.
4. Install a 9 volt radio battery on the circuit board for memory backup, this allows for
retention of the clock and other functions in the event of power failures. Note: Alkaline
batteries are recommended for longer service life.

Tubing Connections
Cut off the proper lengths of LDPE tubing that will reach from the container of product to the inlet
of the Drain Master pump and the outlet of the pump to the drain or grease trap.
Insert the chemical supply tubing into t he end of the ¼” ID JG fitt ing located on the left side of the
pump. The JG fitting must be inserted completely in order to ensure a good seal. The other end of
the chemical supply tubing can be connect ed to the 10” PVC pickup tube that has been supplied.
This should be done by slipping the LDPE tubing through the compression nut and sleeve and into
the threaded end of the pickup tube u ntil LDPE tubing is about ¼” from the bottom of the pickup
tube. The pickup tube can be placed in gallon containers of chemical products. If the pickup tube is
not used, the supply tube should be properly secured to the supply container to assure that chemical
product is delivered.
Insert the outlet tubing into the end of the ¼” ID JG fitting located on the right side of the pump.
The JG fitting must be inserted completely in order to ensure a goo d seal
outlet tubing must be secured into drain or grease trap to assure that chemical product is properly
delivered. It is suggested to use a 1/8” NPT male x ¼” compression fitt ing when fitting discharge
into the side of a drainpipe.
. The other end of the
Programming:
Open the cover on the Drain Master. All of the DIP switches should be visible on the control board
on the backside of the cover. All of these switches must be in the “off” position to begin
programming.
Time Set: Find the DIP switch that corresponds to the closest hour of the current time.
There are 12 DIP switches for AM and 12 for PM. After finding the correct
switch flip it to the “on” position. The “time set” LED will go out.
Feed Time: Using the same switches set the hours in which the Drain Master should
operate by switching the appropriate switch to the “on” position.
Note: If the DIP switch that was set for the “time set” is not a
desirable “feed time”, simply turn that switch to the “off” position.
But not until at least one feed time has been selected. This will insure
tha t the “time se t” will not be lost .
Dosage: There are a series of 6 DIP sw itches that are labeled “dosage”. The number
labe led ne xt to e ach swit ch ind icat es the nu mber o f ounc es to be d ispe nsed.
Example: switch 2 will dispense 2 ounces of product. These may be added
together for higher doses. Example: Switches 5 and 6 in the “on” position
will dispense 11 ounces of product. The maximum is 21 ounces at each
“feed time” that has been set.
Reprogram: Flip all the DIP switches to “off” position.

Priming
After installation is complete the pump and tubing will need to be primed so that chemical product
will be delivered when the Drain Master is running. This is simply done by pressing and releasing
the prime button on the front of the Drain Master; the pump should begin to run. The pump will run
for the amount of dose that has been set.
Note: At any time the Drain Master pump can be shut off by simply pushing the prime button again.
