1. Receiving Pump
Upon receipt a visual check should be made to determine if any damage has occurred during
transit or handling. What to look for?
(a) Broken or cracked components, including base, motor or pump feet and flanges.
(b) Bent pump or motor shaft.
(c) Broken motor end bells or damaged conduit boxes on motor.
(d) Missing parts, damaged coupler guard.
Parts or accessories are sometimes wrapped individually or fastened to the equipment. If any damage or losses
have been incurred, promptly notify your Taco representative and the transit company who delivered the product.
When unloading pump units, lift equally as shown in figures 1& 2.
CAUTION: When using a forklift, particular care should be taken to properly balance the load. The
electric motor may be significantly heavier or lighter than the pump. If possible, use the
original pallet or skid provided.
2. Temporary
Storage
If the pump is not to be installed and operated soon after arrival, store it in a clean, dry place, having slow,
moderate
changes inambient temperature. Steps should be taken to protect the pump from moisture, dust,
dirt and
foreign
bodies. It is recommended that the following procedure is taken: (a) Ensure
that the bearings are packed with the recommended grease, to prevent moisture from entering
around the shaft.
(b) Ensure
that suction and discharge branches of the pump and all other openings are covered with card board,wood or masking tape to prevent foreign objects from entering the pump.
(c) If the pump is to be stored where there is no protective covering, it is advisable to cover the unit with a
tarpaulin or other suitable covering.
3. Preparation
installing the pump, clean the suction and discharge flanges thoroughly.
Before
4. Location
The pump
should be installed as near the liquid source as possible with the shortest and most direct suction
pipe practical.
The pump should be installed with sufficient accessibility for inspection and maintenance. Ample
space and headroom should be allowed for the use of an over head crane or hoist sufficiently strong
to lift the unit.
Make sure there is a suitable power source available for the pump driver. If motor driven, electrical characteristics should be identical to those shown on motor data plate.

5. Foundation (See Fig. 3)
FIG. 3
6. Baseplate Setting (See Fig. 3)
The foundation should be poured without interruptions. The top surface of the foundation should be
well scored and grooved before the concrete sets: this provides a bonding surface for the grout.
Foundation bolts should be set in the concrete. Lower base plate on pad through the anchor holes
on the base plate. Snug up the flange nuts and washer. Allow enough length for grout, and shims.
Use blocks and shims under base for support at foundation bolts and mid way between bolts, to
position base approximately 1" above the concrete foundation with the studs extending through
holes in the baseplate. By adding or removing shims under the base, level the pump shaft and
flanges. The baseplate must be level. The concrete should be allowed to cure for 48 hrs.
Draw foundation bolt nuts tight against baseplate and observe pump and motor shafts or coupling
hubs for alignment.
Check to make sure the piping can be aligned to the pump flanges without placing pipe strain on
either flange.
Grout baseplate completely and allow grout to dry thoroughly before attaching piping to pump (24 hours
is sufficient time with approved grouting procedure).
7. Grouting Procedure (See Fig.3) Visit www.taco-hvac.com for "How To" video presentation.
Grout compensates for uneven foundation,distributes weight of unit and prevents shifting.Use an approved,
non-shrinking grout as follows, after setting and levelling unit: (a) Build strong form around foundation to contain grout.
(b) Soak top of concrete foundation thoroughly, then remove surface water.
(c) Baseplate should be completely filled with grout and, if necessary remove trapped air.
(d) After the grout has thoroughly hardened, check ·the foundation bolts and tighten if necessary.
(e) Check the alignment after the foundation bolts are tightened.
8. Alignment Procedure (See Fig. 4)
The pump driver, if supplied, is correctly aligned on its baseplate at the factory. A certain amount of
misalignment is possible during transit and it is therefore essential to check alignment, prior to final grouting.
A flexible coupling will only compensate for a small amount of misalignment and should not be used to compensate for excessive misalignment of the pump and driver shafts. Inaccurate alignment results in vibration
and excessive wear on the bearings, and seals. Parallel alignment may be checked by placing a straight
edge across the two hubs and measuring the maximum offset at various points around the periphery of the
hubs. Do not rotate shafts. Reposition equipment until offset is as small as possible.
3
FIG. 4
9. Forms of misalignment: - Figure 4
(a) Angular - shafts with concentric axes but not parallel.
(b) Parallel - shafts with axes parallel but not concentric.
To check for angular alignment, insert a pair of inside callipers or taper gauge at four points at 90 degree
intervals around the coupling. Angular alignment is achieved when the measurements at all points around
the coupling faces are within 0.005" of each other.
To check for parallel alignment, place a straight edge across both coupling rims at the bottom, and at both
sides. Parallel alignment is achieved when all points around the OD of the coupler is within 0.005".
Alignment adjustments can be made by shimming under the driver mounting feet. After each adjustment it
is necessary to recheck all features of alignment.
Alignment should be performed after the baseplate has been properly set and grout has dried
thoroughly according to instructions. Final alignment should be made by shimming driver only.
NOTE: Final alignment should be made.at operating temperatures.
10. Suction and Discharge Piping (See Fig. 5 & 6)
Piping should always be run to the pump. Do not move pump to pipe.
This could make final alignment impossible. Both suction and discharge piping should be
supported independently and close to pump so that no strain is transmitted to the pump when
the flange bolts are tightened. Use pipe hangers or other supports at necessary intervals to
provide support. When expansion joints are used in the piping system,they must be installed
beyond the piping supports closest to the pump. It is advisable to increase the size of both
suction and discharge pipes at the pump connection to minimize frictional losses.
CORRECT
INCORRECT
FIG.5
FIG.6
4
A suction diffuser or minimum of 5 pipe diameters of straight pipe of same size is acceptable. It
is not recommended running the suction line parallel with the pump shaft with an elbow
or suction diffuser leading directly to the pump. Install piping as straight as possible,
avoiding unnecessary bends. Where necessary, use long radius elbows or a Taco
suction diffuser at right angles to the pump shaft.
Make sure that all piping joints are air tight. Provide pipe expansions when hot fluids are to be
pumped. Where reducers are used, eccentric reducers are to be fitted in suction lines and
straight taper reducers in discharge and vertical lines. Undulations in the pipe runs are also to be
avoided. This or misuse of reducers may cause the formation of air pockets in the pipe, and thus
preventing the correct operation of the pump.
The suction pipe should be as short and direct as possible. Where suction lift is not very high,
it is advisable to use a foot valve. Horizontal suction line must have a gradual rise to the pump.
The discharge pipe is usually preceded by a non-return valve or check valve and a discharge
gate valve. The check valve is to protect the pump from excessive back pressure and reverse
rotation of the unit and to prevent back flow into the pump in case of stoppage or failure of the
driver. The discharge gate valve is used in priming, starting and when shutting down the pump.
NOTE: Strainers should be installed on the discharge side of the pump to minimize
suction pressure losses.
OPERATION
1. Before initial starting of the pump,make the following inspection:
(a) Pump is primed. Never run the unit dry.The liquid in the pump serves as a lubricant for close fit parts
within the pump. The pump can be damaged if operated dry. The pump can be primed by using an
ejector exhaustless vacuum pump. If a foot valve is used in the suction line the pump can be primed
by venting and filling the casing with liquid.
(b) Check alignment between pump and motor.
(c) Motor is correctly wired to starting device, check voltage, phase and frequency on motor
nameplate with the line circuit. Confirm correct direction of rotation prior to coupling to pump.
Check by starting motor and switching off immediately, confirm rotation is the same as the arrow
direction on the pump casing.
(d) Bearing lubrication is provided (see lubrication section), also check driver lubrication.
(e) Mechanical seal has been fitted or stuffing box has been packed. The packing is allowed to leak
(f)
All rotating components are found to be free when turned by hand.
(g) The pump base plate is grouted and bolted to the foundation pad.
IMPORTANT! These instructions should be read completely prior to installation of the equipment. A
copy of these instructions should be retained on file for future reference. This pump is intended for the
circulation of water or other suitable HVAC media. It is not intended for hazardous, corrosive, or flammable
liquids. Refer to motor instructions to determine proper terminal connections in order to obtain correct pump
rotation. Pump should be installed according to local electrical and safety codes using appropriate
size wire and suitable over current protection. Use a lockable isolator or circuit breaker conforming to
EN60947-3. It is recommended that the pump be fitted with a suitable "EMRGENCY STOP".
SAFETY REQUIREMENTS
Pump must not be operated without guards in place.

2. Starting
Before the pump is started for the first time, it is important to check the
following points.:
(a) Check that the pump rotates freely by hand..
(b) Open the air valve on top of pump casing to evacuate any air that
may be trapped, close vent when all air is removed.
(c) Jog the driver to check for proper rotation.
(d) Start the pump driver.
(e) When the pump reaches operating speed, open the discharge
valve slowly. The pressure will gradually drop as the flow
increases.
Do not operate pump for prolonged periods with closed discharge
valve, so as to avoid overheating.
The pump should be shut down at once if the pump is running at
its rated speed and found to have any of the following
problems: (a) No liquid delivered.
(b) Not enough liquid delivered.
(c) Not enough pressure.
(d) Loss of liquid after starting.
(e) Excess vibration.
(f) Motor runs hot.
(g) Pump bearing overheating
3. Running
While the pump is running, inspect and record the following as baselline data:
(a) Stuffing box (soft packed pumps only). Ensure there is sufficient leakage to lubricate the packing.
(b) Check the bearings for temperature, when pump reaches operating speed and temperature.
(c ) With mechanical seal fitted pumps, check that there is no leakage from the seal area.
(d) Suction and discharge gauge pressure readings (if fitted)
(e) Measure and record vibration readings.
4. Minimum Flow Rate
Taco pumps should not be continually operated at a flowrate below 30% of the best efficiency point unless
otherwise specifically agreed by the manufacturer. If the application is such that zero flow or less than 30%
of original design flow will occur, a return/by-pass line must be fitted to dissipate heat.
5. Stopping
(a) Slowly close the discharge valve as the pump slows to a stop.
(b) Shut off external sealing liquid suppy if supplied, to release stuffing box pressure.
(c) Successful operation of the pump depends on the accuracy of the alignment. It is recommended to
recheck the alignment after preliminary run.

Procedures for long‐term storage
Here are some general suggestions for long term storage. The applicability of all, or some of these
suggestions depend on several factors such as type of equipment, length of storage, and condition of
the environment in which they are stored in:
1. Drain the casing completely and dry it thoroughly, including its bearing housing and stuffing
box, or seal chamber. Apply a coat of soluble rust preventive solution both internally and
externally.
2. Cover all openings. Flanged openings (such as suction and discharge nozzles) should be
covered with blind flanges with elastomer gasket. Threaded openings should be covered
with steel plugs or caps.
3. Remove the shaft coupling; it may cause the shaft to develop a permanent sag during
prolonged storage.
4. Wrap the exposed shaft and key with corrosion inhibitor waterproof paper or waxed cloth.
5. Protect the bearing housing from moisture by placing bags of vapor phase inhibitor crystals
around the housing.
6. Cover the equipment with industrial strength plastic, preferably transparent to allow its
visual inspection, including its nameplate, without uncovering
the unit.
7. Store the unit in its normal position in a dry, temperature controlled environment.
8. Inspect the unit periodically and turn the shaft a few times plus 1/4 turn at least once a
week. Turning the shaft prevents pitting of finished surfaces. The extra 1/4 turn is to
displace the sag and prevent the shaft from developing a permanent bow.
