Delta RP48025 Installation Instructions

1. Read complete instructions and familiarize yourself with the illustrations before beginning. Plumber installation is recommended.
2. WARNING! SHUT OFF WATER SUPPLIES BEFORE DISASSEMBLING TUB SHOWER VALVE.
3. Remove handle.
4. Pull sleeve (1) off. Then, if necessary, slide the O-ring (2) toward you just below the back of the bonnet (3) on the body. Do not pull the
O-ring over the bonnet. Note: When the sleeve (1) is reinstalled, it will slide on this O-ring.
5. WARNING: BE SURE WATER SUPPLIES ARE SHUT OFF!
6. Unscrew the brass bonnet (3) counterclockwise.
7. Determine which series cartridge is currently installed in order to know which replacement cartridge to use. If the cap (4) is white,
a 1300/1400 series cartridge (RP19804) is currently installed. If the cap (4) is grey, a 13/14 MultiChoice™ cartridge (RP46074) is
currently installed. Note: Cartridges are not interchangeable.
8. Remove the cartridge from the body. If a 13/14 MultiChoice™ cartridge (RP46074) is installed, place a flat head screwdriver in the notch (5)
of the cap and turn to raise out of the body.
Note: If a 1300/1400 cartridge (RP19804) is installed, do not pry the cartridge out of the body with a screwdriver. Reinstall the
handle on the brass stem and rotate counterclockwise while lifting the cartridge out of the two notches (6) on the sides of the body.
9. CAUTION! Do not twist the cap (4) and the lower housing (7) of the new cartridge to take it apart. If the parts are separated for any
reason, be sure to lock each together by twisting the parts together until the cap and housing snap together. WARNING! Never take the
lower housing apart.
1. 1300/1400 Cartridge Installation:
Install the cartridge with the wording "Hot Side" located on the hot water inlet side. Press into valve body, making sure the keys (8) are fully
engaged with the slots of the body (6). Note: For back-to-back or reverse installations (hot on right, cold on left) install cartridge with the
wording "Hot Side" on the hot water inlet side. If using a 13/14 MultiChoice™ cartridge, see step 1A below. If not, continue to step 2.
13/14 Multi-Choice Cartridge Installation:
Install the cartridge with the wording "Hot Side" located on the hot water inlet side. Press into valve body, making sure the keys (8) are fully
engaged with the slots of the body (6). Note: For back-to-back or reverse installations (hot on right, cold on left) install cartridge with the

5. See the reverse side for rotational limit stop adjustment.
6. Reinstall the handle, then proceed to step 7.
7. FLUSH YOUR SYSTEM. Turn on water supplies. Check for leaks and let supply lines flush for one minute without moving handle. If you
have a showerhead remove and divert water to it and flush for 30 seconds. This will remove any debris from the supply lines that can
damage internal parts of the faucet and create leaks. BE SAFE! After you have finished the repair, turn on tub/shower valve to make sure
COLD WATER FLOWS FIRST.
