Installation
A ground wire (G), bleed-type master air valve (E), thermal relief valve (H) and fluid drain
valve (J) are required in your system installation. These (user supplied) components help reduce
the risk of serious injury.
•
The ground wire (G) must be connected to the pump grounding lug and to a true earth
ground to prevent static sparking that could result when fluid is dispensed through the hose.
See your local code for specific requirements.
•
The hose reel must be grounded.
•
The bleed-type master air valve (E) relieves air trapped between this valve and the pump
after the air is shut off. Trapped air can cause the pump to cycle unexpectedly, therefore
locate the valve close to the pump.
•
The thermal relief valve (H) and fluid drain valve (J) assist in relieving fluid pressure in the
displacement pump, hose and dispense valve. Triggering the dispensing valve (N) to relieve
pressure may not be sufficient. Open the fluid drain valve (J) to relieve fluid pressure that
may be captured elsewhere in the system.
