PART II
Bowls and brackets:
Materials:
1 ¾” ¼ x 20 screws (6) Bowl and bracket assembly (2) includes mounting plates on back Stainless steel washers (6) Nylock hex nuts(6) Wood or aluminum shims (optional)
1. Locate where the mounting plates for the bowls will be attached (48-‐50” above the floor).
a. Watch for obstruction on the outside of the trailer such as window frames, bolts, doors, etc.
b. Check for angles to stall walls and ability for the horse to reach easily. i. If the angles are too sharp, use two inch wide wood or aluminum plates behind
the mounting plates to bring it forward until the angle will hold the bracket. ii. Adjust screw length
2. Mark the holes for drilling on the inside of the trailer, and drill.
3. Determine the trailer wall depth and select the screws to attach the mounting plate to the inside of the trailer, with the smooth head of the screw and stainless steel washer on the outside of the trailer, and the Nylock hex nuts on the inside of the trailer.
a. Screw thread should not extend past nut. b. We have provided non-‐standard 1 ¾” screws. If they do not fit exactly, then standard
sizes (1 ½” or 2”) may be found at any hardware store.
7
4. Set the bowl and bracket onto the mounting plate and secure by pushing the pin through the holes in the mounting plate and bracket, with the bracket encompassing the mounting plate.
5. Insert the brass coupler at the end of the bowl’s flex tube into the brass quick connect.
Pipes and fittings:
Materials: PEX tubing 25’ Loom clamps (25) ½”Self-‐tapping screws (25) Union tees (2) Elbows (5) Straight connectors (2) Rubber grommets (4) Brass quick coupler (2) Male adapter barb (2)
1. Begin at the pump and plot the course of the tubing. Follow the sides of the wall and the roof line and secure every 12” with a loom clamp and self-‐tapping screw.
a. Begin the PEX tubing in the brass female compression fitting on the end of the pump.
8
b. The female compression adapter comes apart, and the parts are attached to the PEX tubing as illustrated. Insert the PEX tubing into the base of the adapter, tighten the nut over the band, and screw into the base securing the tubing.
c. Any walls that need to be drilled through between the tank location and the stalls should be drilled and covered on both sides with rubber grommets.
2. When the tubing is directly over a mounting plate, cut the tubing with the PEX tool and insert a union tee.
a. Bring the tubing down on the side away from the horse. b. Secure each side of union tee with loom clamps 3-‐4 inches from tee.
3. Continue the tubing from the other side of the union tee until the next mounting plate, and repeat.
4. At the last mounting plate, insert an elbow in the end of the tubing instead of the union tee.
5. Cut a length of tubing so that it extends from the center of each union tee or end elbow to the bottom of the mounting plate.
6. The brass quick coupler and male adapter barb completes the supply line to the bowl. Insert the vertical end of the PEX tubing into the male adapter and coupler (heating the brass to fit).
7. Secure the connected tubing to the wall with a loom clamp about 3-‐4” above the brass quick connect.

Part III:
INSTALLATION INSTRUCTIONS FOR HYDRAHORSE EXTERIOR ACCESSORY
Mounting plates for bowls:
Materials:
Mounting plate Screws (3) Nylock hex nuts (3)
Locate on the outside of the trailer where you want to install the mounting plates for the bowl. They should be placed 50-‐52” from level ground. If the trailer is not on level ground, and you are installing multiple exterior systems, make sure all mounting plates are level with each other.
It is important that the mounting plate locations do not interfere with any interior hardware or fixtures that would prevent the mounting screws from going through the interior wall, such as stall gate hinges, etc.
Drill the holes for the mounting plates and install with the screw heads going from the outside into the trailer wall. Secure with washers and Nylock hex nuts.
(view outside of exterior mount, no washers) (view inside trailer of exterior mount)

Water supply:
Materials:
Wall inserts Brass block elbows (2) Rubber washer
Brass washer Stainless steel washer Brass coupler
PEX tubing 10’ Union tee Union elbows (2) Brass barb fitting
Determine where you want to position the water supply connection on the outside of the trailer. It should be no more than 2 or 3 inches from either side of the mounting plate, and even with the bottom nut of the mounting plate. Drill a 5/8” hole for the wall insert and brass elbows. (see photos)
Connect a brass block elbow to one end of the wall insert with a rubber washer and a brass washer, and insert through the trailer wall from the outside. On the inside of the trailer, connect another brass block elbow to the wall insert with a stainless steel washer with elbow facing upward.
Note: trailer walls vary in depth. We provide 2.5” and 3” inserts. Since the fit has to be exact, you may find you need a different size. We will be happy to exchange them for you.
(inside view) Attach the brass coupler to the outside brass block elbow. When you move a bowl to the outside, the plug at the end of the flex tube attached to the bowl will fit into the coupler.
11
Select the appropriate union (tee, elbow, or straight) to plug into your existing inside water supply tubing and bring the tubing along the inside roof line until it is directly above the brass block elbow. Use loom clamps and tek screws every 12 inches to secure tubing. Use a union tee or elbow to bring down a length of tubing that extends to the brass elbow. Attach the brass barb fitting to the inside brass block elbow. Insert the brass barb fitting into the end of the tubing and secure with a worm clamp.
Note: heating the barb will allow it to fit into the tubing more easily.
Garden hose accessory:
Materials:
Garden hose fitting with barbed adapter Hose and nozzle
Disconnect the bowl and connect the male plug end of the garden hose fitting into the outside coupler and attach the supplied hose. When the system is on, the nozzle will control the flow of water to wash your trailer or horse.

Part IV: OPERATING AND MAINTENANCE INSTRUCTIONS
Operation
1. Fill the tank with water through the fill hole in the top of the tank. 2. Turn on the system at the switch box. 3. Go to the first bowl and push the nozzle until water begins flowing and all
the air and debris are out of the lines to that bowl. 4. Repeat for each bowl. 5. Check for leaks and secure union connections if necessary. 6. Turn off the system at the switch box when the system will not be used.
Maintenance
Bowls The bowls can be cleaned with a soft cloth or non-‐abrasive scrubber and warm water.
Tank Flush with straight water. In extreme conditions, such as hard water build up, use a diluted mixture of chlorine bleach and water (half and half) and FLUSH, FLUSH, FLUSH!
A garden hose fits into the opening at the top of the tank for flushing.
Note: Chemicals are never recommended because the horse may pick up the odor of the chemical and not drink from the system.
Pump Follow pump manufacturer’s instructions (included in the packing).
Note: Do not use compressed air to clear the pump as it will damage the one way valve to the pump.
Note: DO NOT USE RV ANTI-‐FREEZE OR ANTI-‐FREEZE OF ANY KIND!

Part V: Quick Drain Winterizing Instructions 1. Make sure the water level in the tank is high enough to cover the float switch in order for
the pump to run.
2. Close the valve coming from the water tank to maintain the water level for the pump.
3. Disconnect the brass garden hose fittings that connect the flex hose from the tank to the pump filter. Connect a regular garden hose to the garden hose fitting and direct outside.
4. Place a shallow pan beneath the other side of the pump, disconnect the fitting that connects the pump to the PEX tubing and let the water from the pump drain into the pan.
5. Flip the toggle switch to “on” and run the pump until it is dry. Leave all water connections
disconnected. Leave the pan to catch any leftover drainage.
14
6. Now open the water tank valve located between the tank and the garden hose leading outdoors and let drain. Leave open until next filling.
7. Disconnect each bowl flex tube from the brass quick connect and direct the hose downward.
8. Push the nozzle to drain the bowl line completely.
9. At each bowl bracket, inside and outside the trailer if you have an exterior kit, insert a plug (with tube attached) into the quick coupler and leave it in. Water will drain out from the plug and hose, and the plug will keep the quick connect open for expansion while not in use.
Interior Exterior
10. Leave everything open for expansion during freezing temperatures.
11. Reverse this process to fill system again.
