1.0 mechanical setup
This manual contains specific information regarding the safe
installation, operation and maintenance of Armstrong Design
Envelope pumps. Read this manual carefully before installing or
using the product. If clarification is needed on any point please
contact Armstrong quoting the equipment serial number.
1.1 precautions
1.1.1 instructions for safe use
No installation of this equipment should take place un-
less this document has been studied and understood.
Handling, transportation and installation of this equipment
should only undertaken by trained personnel with proper use
of lifting equipment. See later diagrams for lifting advice. Refer
to the pump nameplate for pump speed, pressure and tem-
perature limitations. The limits stated must not be exceeded
without written permission from Armstrong.
1.1.2 ambient temperature
Install the Design Envelope unit with adequate ac-
cess for routine maintenance. A minimum of 2" (50
mm) clearance is required at the fan inlet to facilitate
airflow. Where several Design Envelope units are
installed in close proximity, care must be taken to ensure that
there is no re-circulation of exhausted warm air.
To avoid the inverter unit getting overheated, the
ambient temperature is not to exceed 104°f (40°c)
average daily temperature. Operating in higher
ambient temperatures will require derating of the inverter.
Under normal operating conditions the pump surface tempera-
ture may reach 68°c/ 155°f (Restricted Zone) to 80°c/176°f
(Unrestricted Zone). Steps should be taken to minimize contact
or warn operators/users that normal operating conditions will
be exceeded. In certain cases, where the temperature of the
pumped liquid exceeds the above stated temperature levels,
pump casing temperatures may exceed 100°c/212°f and not
withstanding pump insulation techniques appropriate mea-
sures must be taken to minimize risk for operating personnel.
The ambient temperature for standard motors must be no
greater than 40°c/104°f.
1.1.3 enclosure rating
The standard enclosure rating for Design Envelope 4300 and
Design Envelope 4380 integrated controls is ul Type 12 /
ipp55. If the pump is to be installed in a wet or dusty environ-
ment, then a higher enclosure rating may be required (contact
Armstrong).
1.1.4 storage
Pumps not immediately placed into service, or removed from
service and stored, must be properly prepared to prevent
excessive rusting. Pump port protection plates must not be
removed until the pump is ready to connect to the piping.
Rotate the shaft periodically (at least monthly) to keep rotating
element free and bearings fully functional.
For long term storage (longer than three months), the pump
must be placed in a vertical position in a dry environment.
Internal rusting can be prevented by removing the plugs at the
top and bottom of the casing and drain or air blow out all water
to prevent rust buildup or the possibility of freezing. Be sure to
reinstall the plugs when the unit is made operational. Rust-
proofing or packing the casing with moisture absorbing mate-
rial and covering the flanges is acceptable. When returning to
service be sure to remove the drying agent from the pump.
1.1.5 warranty
Armstrong’s warranty period for Design Envelope pumps
is [18] months from date of shipment, or [12] months from
date of installation, whichever comes first. Please refer to File
9.10us / 9.10c for full terms and conditions. To receive an ad-
ditional [6] months of standard coverage, owner may register
the pump unit at
www.armstrongfluidtechnology.com/warrantyregistration
1.1.6 uncrating
Armstrong Design Envelope 4300 & 4380 Vertical In-Line
pumps are thoroughly inspected before shipment to assure
they meet with your order requirements. After removing the
pump from the packaging, make sure the equipment is in good
order and that all components are received as called for on the
packing list. Any shortages or damage should be reported im-
mediately. Use extreme care in handling the unit, placing slings
and hooks carefully so that stress will not be imposed on the
integrated controls, pump or motor. Never place cable slings
around the pump shaft or integrated controls. The hoist rings
should be used to lift the complete pump assembly.

1.1.7 handling design envelope 4300 & 4380
units
To handle Design Envelope 4300 & 4380 units when received
on site, secure the pallet following uncovering the unit, then
hook straps as detailed below and in fig. 1.1.1, and carefully lift
the pumping unit. Connect the lifting straps around the lifting
rings on each side of the integrated motor. The pumping unit
will not free-stand on the casing ribs. Extra care is required to
ensure the integrated controls do not get damaged during lift-
ing and installation.
As the lifting device is engaged (Using a spacer bar if neces-
sary) and the straps tighten ensure no part of the strapping is
touching any part of the control or motor fan cover.
fig. 1.1.1
important:
Do not run the pump for any length of time under very
low flow conditions at the maximum speed or with the
discharge valve closed.
To do so could cause the water in the casing to reach super
heated steam conditions and will cause premature failure and
could cause serious and dramatic damage to the pump and sur-
rounding area.
1.2 mechanical installation
1.2.1 location
In open systems, locate the unit as close as practical to the
liquid being pumped, with a short, direct suction pipe. Ensure
adequate space is left above and around the unit for operation,
maintenance, service and inspection of parts.
In closed systems, where possible, the pumps should be in-
stalled immediately downstream of the expansion tank /make-
up connection. This is the point of zero pressure change and
is necessary for eective pump operation. Do not install more
than one expansion tank connection into any closed hydronic
system.
Electric motor driven pumps should not be located in damp or
dusty location without special protection.
Airflow into the motor and/or motor fan should not be obstruct-
ed.
It is good practice to leave sucient space around equipment
for operation, maintenance, and service needs.
1.2.2 installation
When installing vertical in-line pumps, an important consid-
eration to accrue full added-value from the pump design is to
ensure that the pump is pipe-mounted and free to float with
any movement, expansion and contraction of the piping. Should
any vertical in-line pump use support to the structure it is
imperative that no pipe strain is imposed on the pump flanges.
Tell-tale pieces of equipment such as springs or wae style
neoprene isolation pads that distort with pressure to indicate
added piping weight, should be used under pump supports
should the pump not be truly pipe mounted.
a hanger supported pipe mounted
4300 & 4380 Vertical In-Line pumps may be installed directly
in the system piping with no additional support. Pipe hangers
are simply sized for the additional weight of the pumping unit.
Many pumps are installed in this manner and can be mounted
at sucient height to take zero floor space.

b pipe mounted supported at ceiling
Piping in many mechanical rooms is hung close to the ceiling
and larger pumps are mounted near ground level for ease of
maintenance. fig 1.2.2 illustrates such an arrangement with
the piping supported at the ceiling and the vil unit installed
with an Armstrong Suction Guide and Flo-Trex valve. Many
very large vil pumps are installed in this manner.

f with stanchion plates
Where required, additional floor support may be used as shown
in fig. 1.2.6 Note that the pump should not be rigidly attached
to the column. Leave a small gap between pump and column or
install a ‘wae’ isolation pad under the pump. It is critical that
piping be installed in such a manner that the pump does not
become a pipe support.

g seismic region installation
fig. 1.2.7 illustrates installations with stanchion plates for seis-
mically active regions. Seismically rated isolation pads or snub-
bers with bolts isolated from the stanchion plates are installed
to restrain the pump during a seismic event. Pipe hangers carry
the weight of the equipment as seismic components are de-
signed only to restrain the equipment during a seismic event.

h mounting in grooved pipe systems
Many Vertical In-Line pumps are piped successfully into
grooved piping systems. In-line pumps are supported well by
grooved piping however flange adapter locking devices or a
welded flange at the pump should be used to prevent the pos-
sibility of pipe mounted pumps rotating in the piping. Armstrong
oers grooved suction guides with cast-in outlet flanges and
Flo-Trex valves with Armgrip™ fittings to prevent this possibility.

Connecting the pump to a permanent rigid base (fig. 1.2.9) is
not recommended unless isolated from the piping by flexible
connectors and the base isolated from the building structure on
an inertia base. (fig. 1. 2.9 is generally acceptable when using
plastic piping).

The motor and integrated control assembly has 2factory
orientations available, each perpendicular to the flow to meet
installation spacing requirements.
Where applicable, remove the coupling guard to access the
motor bolts.Remove the motor bolts to rotate the motor and
integrated control assembly by hand.Care should be taken that
the controls are not damaged during lifting and that the flush-
line, accessories and the coupling guard removal/seal service
window are not compromised following the turn (fig. 1.2.11).
If not convenient for other equipment, motor and controls may
be rotated at installation site at 90˚ increments and the rotating
assembly at up to 45˚ in either direction, provided there are no
physical clashes with other equipment. Remove the clamp ring
between the casing and adaptor/pedestal and careful rotate
the rotating assembly. Note that the seal flush line may need to
be replaced to fit the new orientation.
fig. 1.2.11
l clearance note
fig. 1.2 .12
important:
Design Envelope pumps contain a tapped hole in the motor
bracket above the discharge flange (see fig. 1.2.13) for drain-
ing the well. Pipe this drain hole to a floor drain to avoid over-
flow of the cavity caused by collecting chilled water condensate
or from seal failure.

measure and align the piping flanges well. Always start piping
from pump.
Use as few bends as possible and preferably long radius elbows.

Do not use flexible connectors on the suction or discharge of a
vertical in-line pump, unless the pump is rigidly mounted to a
foundation.
Ensure piping exerts no strain on pump as this could distort
the casing causing breakage or early failure due to pump
misalignment.
All connecting pipe flanges must be square to the pipework
and parallel to the pump flanges.
Suction and discharge pipes may be increased or decreased at
pump nozzle to suit pump capacity and particular conditions of
installation. Use eccentric reducers on suction connection with
flat side uppermost.
Layout the suction line with a continual rise towards the pump
without high points, thus eliminating possibility of air pockets
that may prevent the pump from operating eectively.
A strainer of three or four times the area of the suction pipe,
installed in the suction line, will prevent the entrance of foreign
materials into the pump. C/af" (5 mm) diameter perforations in
the strainer is typical.
In open systems, test suction line for air leaks before starting;
this becomes essential with long suction line or static lift.
Install, at the pump suction, a straight pipe of a length
equivalent to four or six times its diameter; this becomes es-
sential when handling liquids above 120°f (49°c). Armstrong
suction guides may be used in place of the straight pipe run and
in-line strainer.
Install an isolation valve in both suction and discharge lines on
flooded suction application; these valves are used primarily to
isolate the pump for inspection or repair.
Install a non-slam non-return check valve in discharge line
between pump and isolation valve to protect pump from exces-
sive back pressure and to prevent water running back through
the pump in case of driver failure on open systems.
Armstrong ftv triple function valve may be installed in place
of separate check and isolation valves. The ftv valve also
includes a throttling feature which must not be used to throttle
with variable speed pump operating in variable flow systems;
unless the pump is oversized and operating beyond the pub-
lished pump curve.
1.2.4 alignment
Design Envelope units are accurately aligned at the factory
prior to being shipped and do not need re-aligning when in-
stalled. Alignment on a Design Envelope unit may be verified by
assuring an equal and parallel gap between coupling halves on
both sides of the coupling.
2.0 electrical setup
2.1 precautions
Safety, risk of death
All electrical connections should be carried out by
a qualified and authorised electrician in accordance
with local site regulations and the latest issue of the
iee regulations.
Before removing the system must be disconnected
from the mains supply. After switching o, wait for at
least 4minutes for the capacitors to discharge before
opening the cover.
caution
High voltage testing (Megging) of the motor/inverter
may cause damage to the electronic components and
therefore should not be carried out.
2.1.1 ground leakage current
Ground leakage current is primarily caused by the
capacitance between motor phases and the motor
frame. The Radio Frequency Interference (rfi) filter
contributes additional leakage current, as the filter circuit is
connected to ground through capacitors.
The size of the leakage current to the ground depends on the
following factors, in order of priority:
1Switching frequency
2Motor grounded on site or not
The leakage current is of importance to safety during handling/
operation of the Design Envelope pump if (by mistake) the on-
board inverter has not been grounded.
Since the leakage current is >3.5mA (approx. 4-20mA),
reinforced Grounding must be established which is
required if en 50178 is to be complied with. Never use
elcb relays that are not suitable for dc fault currents (type A).
If elcb relays are used, they must be:
• Suitable for protecting equipment with a direct current con-
tent (dc) in the fault current (three-phase bridge rectifier)
• Suitable for power-up with short charging current to Ground
• Suitable for a high leakage current

2.1.2 start/stop of pump
The number of starts/stops via the mains voltage must not
exceed one-time per minute.
If a higher number of starts/stops is required, then the start/
stop digital input must be used (mains voltage directly con-
nected). This is the preferred method of starting and stopping
Design Envelope Pumps.
The three phase mains must be isolated before performing
maintenance of the pump.
2.1.3 additional motor protection
With the exception of supply fuses / MCB’s to protect
the installation (for over-current and short-circuit
protection), no additional overload or over-tempera-
ture protection is required (i.e. thermal overloads).
Protection features include:
• Mains phase loss
• Over voltage
• Under voltage
• Electronic thermal motor protection
• Short circuit on motor terminals
• Ground fault on motor terminals
• Over temperature
2.1.4 motor thermal protection and derating
The Design Envelope motors are thermally protected in case
limits are exceeded (140°c), another protection is provided
thought the drive.
a derating for ambient temperature
The ambient temperature (tamax) is the maximum tempera-
ture allowed.
If the motor is operated at temperatures above 104°f (40°c),
a derating of the continuous output current is necessary.
b derating for air pressure
Below 1000 m altitude no derating is necessary. Above 1000 m
the ambient temperature (ta) or max. rated output current (in)
must be de-rated in accordance with the following diagram.
See the below diagram for derating of output current versus
altitude at ta = Max. 104°f (40°c)
c derating for running at low speed
When a centrifugal pump or a fan is controlled by a 4300
& 4380 Motor, it is not necessary to reduce the output at
low speed because the load characteristic of the centrifugal
pumps/ fans, automatically ensures the necessary reduction.
The 4300 & 4380 Permanent Magnet motors running con-
stant load torque applications continuously at low speed must
be de-rated (see diagram) or an independent fan must be used.
In the Permanent Magnet motors all control terminals are sup-
plied from or in connection with extra low voltage (pelv).
The components that make up the electrical isolation, as de-
scribed below, also comply with the requirements concerning
higher isolation and the relevant test as described in en 50178.

M
d earth leakage current
Earth leakage current is primarily caused by the capacitance
between motor phases and the motor frame. The rfi filter
contributes additional leakage current, as the filter circuit is
connected to earth through capacitors (Cy).
The size of the leakage current to the ground depends on the
following factors, in order of priority:
1Switching pwm frequency
2Motor grounded on site or not
The leakage current is of importance to safety during
handling/operation of the drive if (by mistake) the drive has
not been earthed.
e over voltage protection
The voltage in the intermediate circuit is increased when the
motor acts as a generator. This occurs in two cases:
1The load generates energy.
2During deceleration (ramp-down) if the moment of inertia is
high, the load is low and the ramp-down time is too short for
the energy to be dissipated as a loss in the motor frequency
converter, the motor and the installation.
The drive turns o to protect the igbt transistors and the
intermediate circuit capacitors when a certain voltage level is
reached on DCbus.
f mains supply interference/harmonics
A motor integral drive takes up a non-sinusoidal current from
mains. A non-sinusoidal current can be transformed by means
of a Fourier analysis and split up into sine wave currents with
dierent frequencies, i.e. dierent harmonic currents in with
50 Hz as the basic frequency.
Some of the harmonic currents might disturb communication
equipment connected to the same transformer or cause reso-
nance in connection with power-factor correction batteries.
To ensure low, harmonic currents, for the residential and com-
mercial environments, an optional harmonic filter is necessary.

The number of starts/stops via the mains voltage
must not exceed one-time per minute.
If a higher number of starts/stops is required then the
start/stop digital input must be used (mains voltage
directly connected). This is the preferred method of
starting and stopping Design Envelope Pumps.
The three phase mains must be isolated before
performing maintenance of the pump.

The supply voltage details can be found on the 4300 & 4380
nameplate. Please ensure that the unit is suitable for the
electrical supply on which it is to be used. The mains supply for
Design Envelope pumps is as follows:
1 × 200-230v± 10% ,
3 × 200-230v± 10% ,
3 × 380-480v± 10% ,
3 × 575-600v± 10%

Branch circuit protection
In order to protect the installation against electrical and fire
hazard, all branch circuits in an installation, switch gear, ma-
chines etc., must be short-circuit and over-current protected
according to the national/international regulations. Please refer
to section 8.0 (Fuse and wire recommendation).
Short circuit protection
The inverter must be protected against short-circuit to avoid elec-
trical or fire hazard. The frequency converter provides full short
circuit protection in case of a short-circuit on the motor output.

2.4.3 can bus wiring
Connections, Low, High, and Ground as per fig. 2.4. If the depc requires
a can bus connection, ensure that the terminating resistor switch is set
to Enabled, (towards the en label for the bas ports). If multiple pumps are
connected in parallel for can bus (supplied by others) they should be daisy
chained together. Ensure that only the first and last terminating resistor
switches are set to Enabled.
2.4.4 rs 485 wiring
For Modbus rtu or BACNet ms/tp connection to building automation sys-
tem, connect rs485 cable to this port per fig. 2.4. If the depc is connected
to the bas, ensure that the terminating resistor switch is set to Enabled (to-
wards the en label for the bas ports).
If multiple pumps are connected in parallel to the bas, the bas wiring (sup-
plied by others) should be daisy chained together. Ensure that only the first
and last terminating resistor switches are set to Enabled. See example below
