Tools / Items Needed:
Ice Chest (We use the Coleman 28qt Performance Cooler for our systems) Available at WalMart
Phillips Screwdriver
Drill
Permanent marker
1/4" to 3/4" and 1/4" to 1 3/8" Step Drill Bit Set - Harbor Freight Item #69088
Hot Glue Gun or Attwood Marine Polyurethane Sealant (Available at Wal Mart in the Marine Section)
Begin by selecting the pump location.
Check pump for removal/install clearance. Be sure the pump will be situated in the lowest area of the cooler when the cooler is in the car, plane etc..
Install the pump base. Check pump for removal/install clearance again. Pump must be secured by hot melt glue or marine polyurethane sealant and stainless steel screws.
Decide where you would like to place the through wall adapters on the outside of the cooler and also where you would like the power to attach. Look to see if anything will obstruct the cooler lines or power wires before you begin to drill. be sure to observe the swing of the cooler handle. You don't want it to break off your connectors.
Mark areas to be removed with permanent marker.

Using a drill with a step-drill attachment, drill the three necessary holes on the outside of the unit. The through wall socket adapter holes must be 11/16” and the electrical hole must be 1/4”Drill the inside of the through wall socket holes to 3/4” or larger to accommodate the backing nut, if necessary. You may remove foam as necessary.
Install the through wall sockets and gently tighten the backing nuts, if needed.
Attach pump to pump base. Run pump wires out of electric plug hole.
Attach a foot or two of tubing from upper through wall socket into the cooler.Run tubing from lower through wall socket to pump.
Verify the pump wires are pulled through electric plug hole. Power wires are as follows.
Brown wire is positive +.
Black Wire is negative -.
The pump is designed for 12 volt usage. Please make sure you connect to a 2 to 5 amp fuse in your race car.
Test cooler electrical with a 12 volt power. DO NOT add any water to the unit at this time. Listen to hear if the pump is running. If it runs, proceed. If it does not run, check you electrical connections again. Check your fuse and verify you have powers, if the pump does not run.
Place cooler connector side down. Apply hot melt glue or marine polyurethane sealant to the inside of all three connections to prevent water from seeping out of cooler unit. Allow hot melt glue or marine polyurethane sealant to dry/cure.
Length of cooler to shirt hose is up to you. 6 foot or less is recommended. Cut the remaining tubing into (2) 6 foot lengths. Attach the barbed plugs to one end of the hose. Zip tie the hoses together every 6 inches. Do not over-tighten zip ties. Trim the zip ties.
Trim the end of the hoses evenly and attach the barbed plugs.
Place Ultra Chiller stickers on unit.
Attach the cooler to shirt hose and power adapter to the cooler. Attach hose to shirt, plug power adapter into vehicle and enjoy!
Add a few inches of water and ice cubes.
Please send a picture of your completed unit to sales@ultrachiller.com and we will post it on our website!
