Warnings

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama- tion 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.

WARNING

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. To help prevent fire and explosion:

??? Use equipment only in well ventilated area.

??? Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic drop cloths (potential static arc).

??? Keep work area free of debris, including solvent, rags and gasoline.

???Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes are present.

???Ground all equipment in the work area. See Grounding instructions.

???Use only grounded hoses.

???Hold gun firmly to side of grounded pail when triggering into pail.

???If there is static sparking or you feel a shock, stop operation immediately. Do not use equipment until you identify and correct the problem.

???Keep a working fire extinguisher in the work area.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

???Do not operate the unit when fatigued or under the influence of drugs or alcohol.

???Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals.

???Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer???s warnings. For complete information about your material, request MSDS forms from distributor or retailer.

???Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu- facturer???s replacement parts only.

???Do not alter or modify equipment.

???Use equipment only for its intended purpose. Call your distributor for information.

???Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

???Do not kink or over bend hoses or use hoses to pull equipment.

???Keep children and animals away from work area.

???Comply with all applicable safety regulations.

ELECTRIC SHOCK HAZARD

Improper grounding, setup, or usage of the system can cause electric shock.

???Turn off and disconnect power cord before servicing equipment.

???Use only grounded electrical outlets.

???Ensure ground prongs are intact on sprayer and extension cords.

???Do not expose to rain. Store indoors.

Warnings

WARNING

SKIN INJECTION HAZARD

High-pressure fluid from gun, 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 gun at anyone or at any part of the body.

???Do not put your hand over the spray tip.

???Do not stop or deflect leaks with your hand, body, glove, or rag.

???Do not spray without tip guard and trigger guard installed.

???Engage trigger lock when not spraying.

???Follow Pressure Relief Procedure in this manual, when you stop spraying and before cleaning, checking, or servicing equipment.

BURN HAZARD

Equipment surfaces and fluid that???s heated can become very hot during operation. To avoid severe burns, do not touch hot fluid or equipment. Wait until equipment/fluid has cooled completely.

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.

???Read MSDS???s to know the specific hazards of the fluids you are using.

???Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

???Always wear impervious gloves when spraying or cleaning equipment.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, inhalation of toxic fumes, burns, and hearing loss. This equipment includes but is not limited to:

???Protective eyewear

3.Tubes are color coded. Connect like colors.

NOTICE

To prevent cross-contamination, ensure you connect ???A??? side fluid hose to ???A??? side fluid hose on additional heated hose.

Operation

Operation

1.Select fluid to use for heating circulation.

???50% water and 50% ethylene glycol mixture is recommended for fastest heat-up time and pre- vention of algae build-up regardless of ambient temperature.

???Oil can be used but heat-up time will increase and the hopper fill level must be decreased. See item 2.

NOTE:

Detailed diaphragm pump operating instructions are in the Husky 716 diaphragm pump manual 308981.

2.Fill Heating Fluid in double wall hopper (C) outer cavity. See manual 312747 for instructions.

NOTICE

Do not plug top ports. Always have venting fittings installed to prevent outer cavity pressurization. Failure to do so may cause leakage into spray material.

NOTICE

If oil is the heating fluid selected, the maximum oil level must be 3 in. (76.2 mm) below the hopper side port level. A higher fluid level may cause the oil to overflow during initial pump and heater startup.

NOTE:

If using heated hose: each 50 ft. (15.2 m) heated hose section holds approximately 1.25 gal. (4.7 liters) of fluid.

3.Set the flow rate of the circulation fluid by adjusting the pump???s air regulator (9) until the pump cycles about 50 cycles/min. Do not use a higher flow rate as doing so will decrease system heating perfor- mance and pump life. Never exceed the hose???s

95 psi (0.6 MPa, 6.6 bar) maximum working pres- sure rating.

4.Adjust the heater thermostat to the desired circula- tion temperature. The setting at the heater output thermometer should be about 10?? F (6?? C) higher than the desired paint temperature. Never exceed the hose???s 140?? F (60?? C) maximum temperature rating.See Viscon HP heater manual 309524 for instructions.

NOTE:

If the hose is not being used for more than one hour, shut off Viscon HP heater and pump to lengthen heater life.

Maintenance

???Check double wall hopper heating fluid level monthly. Add fluid as needed.

???Do not overfill when using oil. See overfilling notice on page 18.

Maintenance

???Follow pump maintenance instructions in Husky 716 diaphragm pump manual 308981.

???Follow heater maintenance instructions in Viscon HP manual 309524.
