Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbol refers to procedure-specific risk. Refer back to these warnings. Additional, product-specific warnings may be found throughout the body of this manual where applicable.
Warnings WARNING SKIN INJECTION HAZARD High-pressure fluid from dispense valve, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment. • Do not point dispense valve at anyone or at any part of the body. • Do not put your hand over the end of the dispense nozzle. • Do not stop or deflect leaks with your hand, body, glove, or rag.
Installation Installation NOTICE All installation, maintenance, and repair work must be completed by qualified personnel. Operation Oil Level A System Connections ti13803 ti13804 FIG. 1 • • 4 Install each pumping unit with a high pressure check valve in the discharge line adjacent to the pump discharge connection so that pump assembly may be removed from reservoir without loss of lubricant in lines (FIG. 1).
Operation Pump Priming NOTE: • Three sight glasses (B) are provided in the reservoir at various levels to permit observation of fluid level (FIG. 3). • Oil level should not be allowed to drop below the bottom sight glass. To prime the pump: 1. Turn the feed adjustment nut (C) on the indicator stem as far as possible in a clockwise direction (FIG. 4). C B ti13805 FIG. 3 ti13806 FIG. 4 2.
Operation 3. Replace the vent plug (A). Check the sight glass to insure that it is properly seated against the o-ring (D) to prevent air leakage into the sight well (FIG. 6). A C FIG. 7 D • ti13709 Turn the feed adjustment nut (C) counter-clockwise to reduce the pump stroke and delivery (FIG. 8). FIG. 6 4. Adjust the pumping rate to the desired delivery. Pumping Rate During the pump suction stroke an amount of oil equal to the pump displacement is drawn through the drip tube into the sight well.
Service Service Pressure Relief Procedure A The equipment stays pressurized until pressure is relieved. To reduce the risk of serious injury from pressurized fluid, accidental spray from the dispenser, or splashing fluid, follow this Pressure Relief Procedure whenever you: • Check, clean or service any system equipment. • Install or clean fluid nozzles. 1. Disconnect power supply. 2. Open any bleed-type master air valves and fluid drain valves in the system. 3.
Service • ‘ If these steps do not isolate the malfunction: a. Relieve system pressure, page 7. 2. If items listed in step 1 are not the cause, check the pump assembly. The following items should be checked before removing the pump assembly from the cover. • • Check the sight glass for inward leakage due to a crack in the sight glass, improper sight glass seating, or a defective o-ring. Repair as required (FIG. 6, page 6). b. Disconnect the discharge tubing (E) (FIG. 10). c.
Service • d. Replace vent plug (A). The pump should operate normally. • When the unit is operating the sight level will vary depending on temperature variations. a. If the level falls to less than 1/4 inch above the sight glass flange, add lubricant to the proper level (3/8 inch below the discharge of the drip tube) through the vent hole. If the sight glass continues to fill with lubricant: a. Check all terminal check valves for proper operation. b.
