Cover Mount CAUTION

Do not hang the air accessories directly on the air inlet (E). The fittings are not strong enough to support the accessories and may cause one or more to break. Provide a bracket on which to mount the accessories.

NOTE: Install the accessories in the order shown in Fig. 1.

Wall Mount WARNING

Four accessories are required in your system: an air shut-off valve/air bleed device, fluid drain valve, thermal relief kit, and ground wire. These accesso- ries help reduce the risk of serious bodily injury including fluid injection, splashing in the eyes or on the skin, injury from moving parts if you are adjust- ing or repairing the pump, and explosion from static sparking.

The air bleed device relieves air trapped between it and the air motor after the air supply is shut off. Trapped air can cause the air motor to cycle unex- pectedly, causing serious bodily injury if you are adjusting or repairing the pump. Use either a bleed-type master air valve (A) or a quick-discon- nect coupler (M) and fitting (L). Install near the pump air inlet, within easy reach of the pump.

The fluid drain valve (H) assists in relieving fluid pressure in the displacement pump, hoses and dispensing valve. Triggering the valve to relieve pressure may not be sufficient.

The thermal relief kit assists in relieving pressure in the pump, hose, and dispensing valve due to heat expansion.

The ground wire reduces the risk of static sparking.

1.Screw the muffler (5) into the 3/4-in. npt muffler port, and tighten it using a wrench on the flats of the muffler near the male threads.

2.Install an air line lubricator (N) for automatic air motor lubrication.

3.Install the air regulator (C) to control pump speed and pressure.

4.Install an air line filter (B) to remove harmful dirt and contaminants from your compressed air supply.

5.Install a bleed-type master air valve (A) to isolate the accessories for servicing. See Fig. 1. To order a bleed-type master air valve, order Part No. 107142.

As an alternative to a bleed-type master air valve, you can install an air line quick disconnect coupler

(M) and fitting (L) to serve as an air-bleed device. See Detail A in Fig. 1.

6.Install a drain valve (H) near the pump fluid outlet to relieve fluid pressure in the hoses and gun when opened. To order a fluid drain valve, order Part No. 210658.

7.Install a thermal relief kit (K) on the dispensing valve side of the pump. To order a 1600 psi

(110 bar, 11 MPa) thermal relief kit, order Part No. 240429.

8.Install a suitable fluid hose (P) and dispensing valve (J).
