Installation

Model 233736

Model 233736 surge tank (A) must be installed

horizontally (see Fig. 4).

Install the surge tank on a short riser tube (B) off the

fluid supply line (D). The air inlet must face up.

Install an air pressure regulator (M) and a ball valve

(N) on the air supply line (P) to the surge tank. The air

regulator controls the air pressure in the tank. The ball

valve prevents air from escaping from the tank during

operation.

Install a fluid valve (T) on the riser tube (B). Close this

valve to allow maintenance of the surge tank while fluid

continues to flow in the main fluid supply line.

Remove the plug (12) and install a fluid priming valve

(R) and drain line (S), for use in bleeding air from the

fluid section.
