RECOVERY TANK BLADDER INSTALLATION
1 Mix a one-quart volume of water and soap solution in a small spray bottle then spray the insides of the recovery tank and the outside of the
bladder just before installing. This needs to be done to help the bladder slide easily when positioning it in place. Note: Do not use any silicone-
based products that will be in contact with the bladder, damage to the bladder will result.
2 Install the special rope and pulling bar inside the bladder as shown. Service Tip: Figure 5 shows the dimensions for building the pulling tool
needed to install the drain fi tting through the bottom tank mounting hole.
3 Next feed the end of the rope from the drain fi tting of the bladder through the bottom of the tank hole to the outside.
4 Carefully push the bladder down into the recovery tank with the needed assistance of pulling on the rope.
5 Working through the tank drain outlet opening pull the rope and pry the bladder tube fi tting down where it is partially visible.
6 Spray additional soap solution through drain hole and hold the rope fi rmly while prying down on the fi tting using a screwdriver to keep the fi tting
from pulling away from the tank hole (use caution to not damage the bladder).
7 Remove the screwdriver and quickly slide in a piece of a rounded end steel shafting (approximately 3/4” in Diameter and 18” in length, a large
auto mechanics breaker bar works well) into the drain opening.
8 Pull down on the rope and quickly pull up on the lever turning and drawing the drain tube into the tank hole opening. Next pull out from the top
bladder opening the drain tube pulling tool by its free rope end.
9 Reinstall all of the previously removed plumbing fi ttings, support straps, hardware and hoses. Service Tip: To easily install the plastic drain
hose Bushing (U) onto the aluminum drain tube drop the bushing into a small cup of warm water to soften.
10 Fill the solution tank and check for leaks.
