VALVE INSTALL INSTRUCTIONS

Step 1:  EMPTY AND FLUSH HOLDING TANKS!! This will make your installation an uneventful success.

Step 2:  Remove the four bolts holding the existing manual dump valve to plumbing.

Step 3:  Separate plumbing enough to remove existing manual valve.

Step 4:  Remove the 2 seals from pipe flanges or from existing manual valve.

     IMPORTANT   ** the old seals will not work with your new valve. **

Step 5:  Clean pipe flanges, check for cracks, replace flange if necessary.  Remove caution card from gate area on new       valve.

Step 6:  Make sure valve is in the closed position before proceeding to next steps.  (Valve is shipped with the gate closed)

Step 7:  Now you are ready to install the new valve.  IMPORTANT! Use the seals that came with your new valve. Note: Seals will be found installed on valve, please remove. Place the seals over the flange lip which is located on existing plumbing,

FLANGE

Step 8:    Apply supplied lubricant (Dow 111) to both sides of gate.

Step 9:  Separate pipe flanges and insert Drain Master with gates closed making sure the seals are in their correct position on the flanges. See Step 7.  Rotate the valve to align the four bolt holes with the flange holes and insert the four new bolts and nuts.  See picture below:

Step 10:  Install the four bolts and hand tighten.  Use a 7/16” wrench and in a crisscross pattern, snug the nuts down ¼ turn at a time.  Tighten the four bolts evenly, being careful not to over tighten.  The components are plastic and can crack.  The tightening spec is 20 inch pounds.

Step 11:  Add water to holding tank and check for leaks.

NOTE:  HOW TO INSTALL

OPERATOR SWITCH INSTALLATION INSTRUCTIONS

1.  If you purchased the DM20-RP kit, you will insert the switch through the black switch plate making sure the red and white wires on the switch are on top toward open.  **Red & white wire must be on top toward open, or your valve will operate in the opposite direction**  

2.  Install the switch in a convenient location on your coach, mount with the four screws (included)

3.  You will need to install a 5 AMP in-line glass-type fuse to protect the motor.  ***The fuse needs to be in line between the battery positive source and the switch.  You may use an existing spare fuse on a fuse block or use an in-line type.

Note:  Connectors are provided with the enclosed DM20-RPMS Drain Master kit to show proper wire hookup between switch and valve. You may purchase extension cables with mating connectors by calling our toll free number – 877-787-8833. Cables are available in 2’, 4’, 6’, 8’, and 10’ lengths.  Or you may extend the cables to as you see fit.  Wire minimum: 20 gauge

If you choose to cut off the connectors and hard wire your operator switch to the valve, please use following wiring instructions:

IMPORTANT – CONNECT –

• Black lead on switch – fused connect to positive 12VDC only
• Green lead on switch – connect to negative (ground)
• Red wire from switch – connect to red wire on valve
• White wire from switch – connect to white wire on valve
• If you have the LED switch version, the two labels on the switch that are labeled “To Mag Switch” need to be connected to the two wires on the magnetic switch.  See schematic below.  You can also visit our web site for a larger viewing of this diagram (www.drainmaster.com)

NEW FEATURES

• If you have purchased the DM20RP and wish to upgrade to the LED version, remember it is easier to use the upgrade kit before the valve is installed.  (Call 877-787-8833 to find out about upgrade)
• Double Sided manual override with hex head.  Allen Wrench is provided with the valve – secured on the back of the valve.  Make sure you install your valve with easy access to the manual override.
• Should you ever lose power to your RV, you can open/close the valve manually. Just locate the provided 1/8” Allen Wrench on the back of the valve, insert wrench in the hex head opening, the words open/close with directional arrows will show you which  way is open and which way is closed.  There will be resistance when turning as you are overriding a safety clutch.  Turn until shaft stops. When convenient, check and correct electrical problems.  (A stripped override caused by excessive use is not covered under warranty.
• NOTE:  Unless you have specifically ordered a heavy duty operator switch for your valve, the switch is not weatherproof and should be mounted in an area protected from moisture.  Weatherproof switches are available for purchase.

DRAIN MASTER OPERATING INFORMATION

Note:  Do not hold the switch down longer than 2 seconds

Congratulations on your purchase of a quality product from Phase Four Industries.  You new Drain Master valve is extremely easy to use but may require maintenance.  After installation has been completed according to the installation instructions you are ready to open the Drain Master for the first time.

Push the switch up toward the word “open” and listen for the Drain Master to make a sound.  The Drain Master will open in approx. 1-2 seconds which means you do not have to hold the switch in the open position for more than 2 seconds.

NOTE:  If the valve does not open, check to be sure you have 12VDC to the black wire and that the green wire is ground (if hard wired).  Check to see that the unit does not open when you push the switch toward the “close” position.  If this happens, your switch is upside down.  Be sure you have not over tightened the four bolts holding the Drain Master to the couplings and that the seals were installed correctly.
