DANGER

WARNING

CAUTION

WARNING

Goulds Water Technology High Temperature 3885 Series Efﬂuent pumps are recommended for use in High Temperature applications up to 200ºF. The High Temperature 3885 Pump handles ¾” solids . Common applications include boiler blow down and High Temperature condensate. Pump should be operated with a High Temperature ﬂoat switch sold separately.

SAFETY INSTRUCTIONS

TO AVOID SERIOUS OR FATAL PERSONAL INJURY OR MAJOR PROPERTY DAMAGE, READ AND FOLLOW ALL SAFETY INSTRUCTIONS IN MANUAL AND ON PUMP.

THIS MANUAL IS INTENDED TO ASSIST IN THE INSTALLATION AND OPERATION OF THIS UNIT AND MUST BE KEPT WITH THE PUMP.

This is a SAFETY ALERT SYMBOL. When you see this symbol on the pump or in the manual, look for one of the following signal words and be alert to the potential for personal injury or property damage.

Warns of hazards that WILL cause serious personal injury, death or major property damage.

Warns of hazards that CAN cause serious personal injury, death or major property damage.

Warns of hazards that CAN cause personal injury or property damage.

NOTICE: INDICATES SPECIAL INSTRUCTIONS

WHICH ARE VERY IMPORTANT AND MUST BE FOLLOWED.

THOROUGHLY REVIEW ALL INSTRUCTIONS AND WARNINGS PRIOR TO PERFORMING ANY WORK ON THIS PUMP.

MAINTAIN ALL SAFETY DECALS.

All electrical work must be performed

by a qualiﬁed technician. Always follow the National Electrical Code (NEC), or the Canadian Electrical Code, as well as all local, state and provincial codes. Code questions should be directed to your local electrical inspector. Failure to follow electrical codes and OSHA safety standards may result in personal injury or equipment damage. Failure to follow manufacturer’s installation instructions may result in electrical shock, ﬁre hazard, personal injury or death, damaged equipment, provide unsatisfactory performance, and may void manufacturer’s warranty.

Standard units are not designed for use in

swimming pools, open bodies of water, hazardous liquids, or where ﬂammable gases exist. These ﬂuids and gases may be present in containment areas. Tank or wetwell must be vented per local codes.

Only pumps speciﬁcally Listed for Class 1, Division 1 are allowable in hazardous liquids and where ﬂammable gases may exist. See speciﬁc pump catalog bulletins or pump nameplate for all agency Listings.

Disconnect and lockout electrical power

before installing or servicing any electrical equipment. Many pumps are equipped with automatic thermal overload protection which may allow an overheated pump to restart unexpectedly.

Do not use pump flammalde or explo-

sive liquids. Pump is for water only.

PRE-INSTALLATION CHECKS

Open all cartons and inspect for shipping damage. Report any damage to your supplier or shipping carrier immediately.

Important: Always verify that the pump nameplate Amps, Voltage, Phase and HP ratings match your control panel and power supply.

This pump is oil-ﬁlled. If there are any signs of oil leakage or if the unit has been stored for an extended period check the oil level in the motor dome and the seal housing, if so equipped.

Check the motor cover oil level through the pipe plug on top of the unit. The motor chamber oil should just cover the motor. Do not overﬁll, leave room for expansion!

WARNING

Hazardous voltage

WARNING

Hazardous voltage can shock, burn or cause death.

To check the seal housing oil level, where used, lay the unit on its side with the ﬁll plug at 12 o’clock. Remove the plug. The oil should be within ½” (13mm) of the top. If low, reﬁll with an ASTM 150 turbine oil. Replace the plug.

Oil is available in 5 gallon cans through our distributors. You can also source oil locally at motor repair shops. Typical oil brands are: Shell Turbo 32, Sunoco Sunvis 932, Texaco Regal R&O 32, Exxon Nuto 32 and Mobil DTE Light.

Check the strain relief nut on power cable strain assemblies. Power cables should be torqued to 75 in. lbs., cable supplied is for high temp use.

Warranty does not cover damage caused by connecting pumps and controls to an incorrect power source (voltage/phase supply).

Record the model numbers and serial numbers from the pumps and control panel on the front of this instruction manual for future reference. Give it to the owner or afﬁx it to the control panel when ﬁnished with the installation.

FOR ALL SES PUMP INSTALLATIONS

LIFTING OF PUMP

DO NOT LIFT, CARRY OR HANG PUMP BY THE ELECTRICAL CABLES. DAMAGE TO THE ELECTRICAL CABLES CAN CAUSE SHOCK, BURNS OR DEATH.

Lift the pump with an adequately sized chain or cable attached to the lifting eye bolt. DO NOT damage electrical cables while raising and lowering unit.

OPTIONAL GUIDE RAIL OR LIFT-OUT SYSTEM

In many efﬂuent and sewage basins or lift stations it is advisable to install the pump on a guide rail system or on a lift-out adapter to facilitate installation and removal for inspection and/or service. Most codes do not allow personnel to enter a wetwell without the correct protective equipment and training. Guide rails are designed to allow easy removal of the pump without the need for entry into the wetwell or need to disturb piping. The guide rail or lift-out adapter should locate the pump opposite the inﬂuent opening preventing stagnate areas where solids can settle. The basin or pit must be capable of supporting the weight of the pump and guide rail. The pit ﬂoor must be ﬂat.

NOTICE: FOLLOW THE INSTRUCTIONS THAT ARE

PROVIDED WITH THE GUIDE RAIL ASSEMBLY.

PIPING

Discharge piping should be no smaller than the pump discharge diameter and kept as short as possible, avoiding unnecessary ﬁttings to minimize friction losses. Piping should be rated for high temperatures if used in high temperature applications.

Install an adequately sized check valve matched to the solids handling capability of the pump to prevent ﬂuid backﬂow. Backﬂow can allow the pump to “turbine” 4

backwards and may cause premature seal and/or bearing wear. If the pump is turning backwards when it is called on to start the increased torque may cause damage to the pump motor and/or motor shaft and some single-phase pumps may actually run backwards.

Install an adequately sized gate valve AFTER the check valve for pump, plumbing and check valve maintenance.

Important – Before pump installation. Drill a 3⁄16” (4.8mm) relief hole in the discharge pipe. It should be located within the wetwell, 2” (51mm) above the pump discharge but below the check valve. The relief hole allows any air to escape from the casing. Allowing liquid into the casing will insure that the pump can start when the liquid level rises. Unless a relief hole is provided, a bottom intake pump could “air lock” and will not pump water even though the impeller turns.

All piping must be adequately supported, so as not to impart any piping strain or loads on the pump.

The pit access cover must be of sufﬁcient size to allow for inspection, maintenance and crane or hoist service.

WIRING AND GROUNDING

Important notice: Read Safety Instructions before proceeding with any wiring.

Use only stranded copper wire to pump/motor and ground. The ground wire must be at least as large as the power supply wires. Wires should be color coded for ease of maintenance and troubleshooting.

Install wire and ground according to the National Electrical Code (NEC), or the Canadian Electrical Code, as well as all local, state and provincial codes.

Install an all leg disconnect switch where required by code.

Disconnect and lockout electrical power before performing any service or installation.

The electrical supply voltage and phase must match all equipment requirements. Incorrect voltage or phase can cause ﬁre, motor and control damage, and voids the warranty.

All splices must be waterproof. If using splice kits follow manufacturer’s instructions.

Select the correct type and NEMA grade junction box for the application and location. The junction box must insure dry, safe wiring connections.

Seal all controls from gases present which may damage electrical components.

FAILURE TO PERMANENTLY GROUND THE PUMP, MOTOR AND CONTROLS BEFORE CONNECTING TO POWER CAN CAUSE SHOCK, BURNS OR DEATH.

SELECTING AND WIRING PUMP CONTROL PANELS AND SWITCHES

FLOAT SWITCH TYPES

High Temp ﬂoats can be purchased for High Temp applications. They are normally open (NO) for pump down operations.
