2 Introduction This instruction covers the typical installation of any HL Series pump regardless of the model or intake and discharge. General Description The HL series are pedestal mounted fire pumps designed to operate in to modes: Low Pressure Mode Pump only low pressure water. High Pressure Mode Simultaneously pump low and high pressure water. Maximum Low Pressure Three performance levels are available: Before operating the HL pump, read the following instructions carefully. Control the speed of the pump so that the maximum low pressure is limited to 17 bar. Maximum High Pressure The maximum high pressure is internally limited by the high pressure relief valve not to exceed 55 bar. Maximum Angle of Inclination The maximum angle of inclination for pump operation is 15 degrees. Low Pressure Operational Limits Maximum Pump Speed The pump has a maximum operating speed of 3450 rpm. Do not exceed this speed. Maximum Priming Speed High Pressure Model Series bar bar HL bar bar HL bar bar HL400 When priming, the pump speed should be limited to 2600 rpm.

4 Pump Mounting Select a mounting location that will make the pump and its accessories readily available for maintenance. Provide room around the pump for all intended piping, instrumentation and drive system. Pump Mounting Flange For mounting holes are located on the pump pedestal that are to be used to secure the pump to a mounting plate (plate not supplied by Waterous). The mounting plate should be designed with the four mounting holes (see diagram below for dimensions). The plate should also provide clearance for the volute flange as identified in the diagram below. Attach the pump to the mounting plate and secure to the vehicle with M16 bolts. Tighten fasteners to the following specifications: ( lb-ft). N m Driveline Connection The pump mounting location should be such that the driveline shaft length and angles are in accordance with the driveline manufacturer's specification. Connect the driveline to the companion flange provided on the pump input shaft. use appropriate fasteners and torque following the driveline manufacturer's specification. Pump Mounting F 1031, Section 3032 Page 4 of 13

5 Pump Intake If piping is to be attached to the pump intake, provisions must be made to allow the removal of the pump intake adapter while the pump remains in the vehicle. This is necessary to provide access to the pump for repairs and maintenance. A suitable strainer should be installed in each intake opening on the pump. Low Pressure Discharge Any piping connected to the low pressure discharge openings on the pump discharge manifold must be properly supported and secured. High Pressure Discharge Any piping connected to the high pressure discharge opening on the pump discharge manifold must be suitable for high pressure and properly supported and secured. High Pressure Inlet Strainer Pump installation should provide access as this is a maintenance item. High Pressure Relief Valve Pump installation should provide access as this is a maintenance item. Thermal Relief Valve The valve is designed to discharge water if the temperature of the pump water reaches 49 C. The discharged water must be diverted away from the pump operator. Install a suitable 1/2 in. fitting and tube or hose assembly and route to one of the following locations: To the holding tank, vehicle tank or to atmosphere (ground). The piping must not be restricted in any way. Installation of Components F 1031, Section 3032 Page 5 of 13

6 Clearance for Service The pump has (2) two automatic piston primers located on each side of the pump pedestal. Pump installation must provide 50 mm (2 in.) of space behind the primers to allow them to be removed for servicing. Piston Primers Primer Discharge The piping or hose must not be restricted in any way. During operation, the primers can discharge water. This water exits through the primer discharge outlets. It is important that this water is not restricted in any way. Typically the water is discharged to the ground. A suitable hose may be used to assist in directing the water to the ground, however, it is not recommended that any angled fittings be used as they will restrict the flow. Piston Primers F 1031, Section 3032 Page 6 of 13

7 Lubrication Pump installation must provide for access to the lubrication fills and drains. Models HL200 and HL300D Pedestal (Primer Housing) Fill and Drain - HL200D, HL300D Models HL200K, HL300K, HL300D, HL400D Pedestal (Primer Housing) and K Series Transmission Fill and Drain See next page for K Series Transmission requirements. F 1031, Section 3032 Page 7 of 13

8 Lubrication Pump installation must provide for access to the lubrication fills and drains. Models HL200K, HL300K and HL400K Only F 1031, Section 3032 Page 8 of 13

9 Pump Water Drains The pump is provided with two (2) 3/8 in. BSPT taps to allow water to be drained. Once is located on the low pressure stage volute and one on the high pressure stage volute. The drains should be fitted with valves and piping. The piping should be routed to a suitable draining location. All piping, fittings and valves must be suitable for pressures that are present in the low and high pressure stages. Pump Water Drains Drain Taps If Optional Control Panel was not furnished: The pump includes a magnetic pick-up installed in the pump pedestal which allows a tachometer to be connected. A 10 meter cable is included with the pump which mates with the magnetic pick-up (Amphenol connector part no. MS3106A-10SL-4S). Wire the cable to the tachometer. Note that the magnetic pick-up produces four pulses per revolution of the pump shaft. Tachometer Connection Optional Items If Optional Control Panel was furnished: The tachometer is included in the control panel and the wiring to the magnetic pick-up was completed at the factory.

13 Final Checks Lubrication Before operating the pump, add the lubricants specified below (see Pages 7 and 8 for fill locations.) 1. Capacities shown are approximate. Quantities listed vary based on ratio and /or mounting orientation. 2. Always fill to the marking on dipstick (pedestal) or bottom of the plug labeled Oil Level (K Series Transmission). 3. K Transmission breather may be removed and the hole used as the lubricant fill. 4. Synthetic oil substitutes are acceptable. Models HL200D, HL300D and HL400D Lubrication required for Pedestal (Primer Housing) Only Pedestal (Primer Housing) Lubricant SAE 10W-30 Motor Oil Capacity.95 Liter (1 Quart) Models HL200K, HL300K and HL400K Lubrication required for Pedestal (Primer Housing) and K Series Transmission Pedestal (Primer Housing) Lubricant SAE 10W-30 Motor Oil Capacity.95 Liter (1 Quart) Lubricant SAE 80W-90 Gear Oil K Series Transmission Capacity.95 Liter (1 Quart) Failure to properly lubricate the pump may result in serious damage. Testing Before operating the pump, check and verify all fasteners and connections (mounting, driveline, piping, etc.) are secure. During the running of the pump, monitor for smoothness of operation, listen for unusual noises and check for leaks. To run the pump, follow instructions F-1031, Section 2408, HL Series Fire Pump Operation and Maintenance Instructions. F 1031, Section 3032 Page 13 of 13
