Assembling the Wall Mount Unit

Install

the wall bracket (2) 5 ft (1.52 m) above the floor Use the mounting hole layout shown on page 18. Be sure the wall is strong enough to support the weight of the pump and hoses, any accessories, the fluid, and stress caused by pump operation.

The following steps apply to Model 236–414 only:

Apply thread sealant and screw the connector (28) into the pump’

s fluid inlet. See Fig. 2.

Slide the bung plug (31) onto the suction tube (33). Push the 0.625 in. (16 mm) OD suction tube into the elbow (30) to its full depth, then tighten the nut secure ly with a wrench.

Push the 0.5 in. (13 mm) OD flexible tube (29) into the elbow (30) to its full depth, then tighten the nut secure ly with a wrench. Push the other end of the flexible tube into the connector (28) to its full depth, then tight en the nut securely with a wrench.

Screw the bung plug (31) into the drum bung opening. Adjust the suction tube (33) so the end of the tube is about 1/2 in. (13 mm) of

WARNING

A bleed-type master air valve (B) is required in your system to relieve air trapped between this valve and the pump. Trapped air can cause the pump to cycle unexpectedly serious injury the skin, injury from moving parts, or contamination from hazardous fluids.

A fluid drain valve (J) is required in your system to relieve pressure in the hose if it is plugged. (The fluid recirculation valve supplied with Models 236–870, 224–833, and 236–412 will serve this purpose.) The drain valve reduces the risk of seri ous injury skin, or contamination from hazardous fluids when

relieving pressure. Install the valve close to the pump’

s fluid outlet.

Install the air line accessories as shown in Figs. 3 and 4. Mount these accessories on the wall or on a bracket. Be sure the air line supplying the acces sories is grounded.
