QP-402H PRE-SETUP Pump | Multiquip qp-402h specification

Pre-Setup (Pump)

1.Read safety instructions at the beginning of manual.

2.Place pump as near to water as possible,onafirmflat,levelsurface.

3.Toprimepump,removefillcap(Figure2)andfillpumpcasing with water. If the pump casing is not filled with water before starting, it will not begin pumping.

CAUTION - Pump Casing

Pump casing must be filled with water before using pump. Otherwise pump will not be able to begin pumping.

WARNING - High Pressure

DO NOT open fill cap if pump is hot! Water inside may be under pressure. The possibility exists of scalding, resulting in severe bodily harm.

4.Checkforleaksbetweenpumpandengine.Ifwaterisleaking between the pump and engine housing, the seal inside the pumpmaybewornordamaged.Continued operationofthe pumpisnot recommended.Furtherusageofthe pumpunder theseconditionsmaycauseseverewaterdamagetoengine.

Hoses and Clamps

1.Check that all hoses are securely attached to the pump. Make certain suction hose (Figure 2) does not have any air leakage.Tighten hose clamps and couplings as required.

2.Itisrecommendedthat 2 clampsbeusedwhensecuringthe suction hose to the inlet side (suction) of the pump.

3.Remember suction hoses must be rigid enough not to collapse when the pump is in operation.

4.Check that the discharge hose (Figure 2) is not restricted. Place hose so that it lays as straight as it is possible on the ground. Remove any twists or sharp bends from hose which may block the flow of water.

Suction and discharge hoses are

NOTE available from Multiquip. Contact your nearest dealer for more information.

5.The discharge hose is usually a collapsible (thin-walled) hose, however if a thin-walled discharge hose is not avail- able, a rigid suction hose can be substituted in its place.

6.Make sure the suction strainer (Figure 2) is clean and securely attached to the water end of the suction hose. The strainer is designed to protect the pump by preventing large objects from being pulled into the pump.

CAUTION - Strainer

The strainer should be positioned so it will remain completely under water. Running the pump with the strainer above water for long periods can damage the pump.

CAUTION - Flammable Fluids-Chemicals

DO NOT pump flammable fluids, corrosive chemicals or fluids containing toxic substances. These fluids can create potentially dangerous health and environmental hazards. Contact local authorities for assistance.

CAUTION - Mechanical Seal

This pump uses a water-cooled mechanical seal to prevent water from seeping into the engine. The passage of water through the pump casing lubricates the seal and prevents it from overheating. NEVER! operate the pump without water in the casing as this will cause damage to the mechanical seal.
