1.0 introduction
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
unless this document has been studied and under-
stood. 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 temperature 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
access 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 depm unit getting overheated, the
ambient temperature is not to exceed the average
daily temperature. Operating in higher ambient
temperatures will require derating of the depm unit (See
section 2.1.4 for details).
Under normal operating conditions the pump surface
temperature may reach 155°f/68°c (Restricted Zone) to
176°f/80°c (Unrestricted Zone). Steps should be taken to
minimize contact or warn operators/users that normal op-
erating 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 212°f/100°c and not withstanding pump insulation
techniques appropriate measures must be taken to minimize
risk for operating personnel.
1.1.3 enclosure rating
The standard enclosure rating for Design Envelope
4200H and Design Envelope 4280 integrated
controls is ip55. If the pump is to be installed in a
wet or dusty environment, then a higher enclosure rating
may be required (contact Armstrong).
1.1.4 vibration levels
Armstrong end-suction horizontal pumps are designed to meet vibration levels set by Hydraulic Institute Standard hi Pump
Vibration 9.6.4. Standard levels are as detailed below

1.1.5 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
material and covering the flanges is acceptable. When
returning to service be sure to remove the drying agent from
the pump.
1.1.6 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
additional six [6] months of standard coverage, the owner
may register the pump unit at:
www.armstrongfluidtechnology.com/warrantyregistration
1.1.7 uncrating
Armstrong pumping units 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 immediately. Use extreme care
in handling the unit, placing slings and hooks carefully so that
stress will not be imposed on the integrated controller, pump
or motor. Never place cable slings around the pump shaft or
integrated controls.
1.1.8 handling design envelope 4200h & 4280
pumping units
To handle Design Envelope 4200h & 4280 units when
received on site, secure the pallet after uncovering the unit,
then hook straps as detailed below and in fig 1.1.1 to lift the
pumping unit. Connect one set of lifting straps to the lifting
rings on each side of the integrated motor. A second lifting
strap should be secured around the suction nozzle.
fig 1.1.1
Extra care is required to ensure the integrated controls do
not get damaged during lifting and installation. As the lifting
device is engaged (using a spacer bar if necessary) and the
straps tighten, ensure no part of the strapping is touching any
part of the control or motor fan cover.
The Design Envelope 4200h and 4280 pumping units 0.75-
7.5kW are equipped with integral vibration isolators. Note
that the springs are temporarily secured to the pumping unit
by 4sets of packaging sleeves. These must be removed once
the pumps are positioned in place.

important:
Do not run the pump for any length of time under very
low flow conditions 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
surrounding 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
installed 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
obstructed.
It is good practice to leave sucient space around equipment
for maintenance and service needs. If the Design Envelope
controls are supplied with integral disconnect switches,
3 6"/ 1 meter clearance may be required in front of the
controls to meet local electrical codes.
1.2.2 installation
The Design Envelope 4200h and 4280 pumping units
0.75-7.5kW are equipped with integral vibration isolators
and do not require inertia bases or baseplates for horizontal
(shaft orientation), base-mounted installations. The vibration
isolators are pre-sized for the pumping unit and will reduce
the transmission of noise and vibration from the pump and
piping system to the building structure.
fig 1.2.1
The springs use anti-friction neoprene cup mounts and
prevent lateral movement of the pump. If accurate positioning
of the spring cups is required, gently use a tool, such as the
end of a flat-head screwdriver (or crowbar) to tap the cups
into place.
fig 1.2.2
1.2.3 system installation
Refer to fig 1.2.3 for the recommended installation of
Design Envelope 4200h and 4280 pumping units 0.75-
7.5kW pumps.

Note the springs on the inertia base must be locked out to
allow the pump's integral springs to operate properly.
fig 1.2.3b
If the installation uses horizontal inlet piping, a flex connector
should still be installed before the suction port of the pump.
fig 1.2.3c
1.2.4 suction guide
It is recommended that suction guides be mounted directly
to the pump’s suction port. This acts as a counter weight
to the weight of the motor to ensure the center of gravity is
maintained between the front and back springs isolators.
A support pipe under the suction guide should not be used
– this may transmit forces from the pump or piping system
to the ground structure, resulting in unwanted noise or
vibration.
fig 1.2. 4
Flex connectors should be installed directly before the suc-
tion guide (or suction port), and directly after the pump’s dis-
charge port. This will eectively isolate the transmission of
noise or vibration between the piping system and the pump.
1.2.5 leveling
It is recommended that the Design Envelope 4200h and
4280 pumping units 1-10hp pumps be leveled for general
pump operation. Note that these pumps are equipped with
support blocks to help pre-level the assembly and provide
stability during installation to the piping system.
Once water is added to the piping system, the pumps must
be levelled to the final operating weight. Start by removing
the shrouds from the front and back of the pump fig 1.2.5.
Lift the shrouds up to detach from pump, then remove the
two shroud halves apart.
Turn the rubber knobs and
continue even adjustment of
all mounts until all springs
are loaded and mountings are
back to Free and Operating
Height. It is important that the
mounts are all adjusted evenly
by working in a clockwise or
counter-clockwise pattern
as the springs are adjusted.

Ensure that the support blocks are removed once the springs
are all levelled. The support blocks must be removed for
proper vibration isolation (See fig 1.2.5a).
The shrouds can then be re-assembled to the pump by
fastening the 2halves together around the pump foot and
motor foot. Push the shroud assembly down and ensure the
shroud pins click into the locator holes in the castings.
fig 1.2.5a
1.2.6 installation for seismic mounts
Pumps equipped with the
Seismic Mount option have
seismic mounts factory
pre-installed to the feet and
must be bolted to the ground
structure. Anchor rods may be
either cast-in place or post-
installed. Ensure the anchoring
and mounts are installed along

1.2.7 vertical shaft installation
Design Envelope 4200h and 4280 pumping units 0.75-
7.5kW may be safely installed in a vertical shaft orientation
as shown in fig 1.2.7. The motor fan must be in an upright
position; with the suction port facing down. When installed
vertically, the integral springs and shrouds should be
removed from the base of pump.
fig 1.2.7
1.2.8 pump piping – general
Never connect a pump to piping, unless extra care is taken
to measure and align the piping flanges well. Always start
piping from pump.
Use as few bends as possible and preferably long radius
elbows.

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. 3mm (V") 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
essential when handling liquids above 49°c (120°f).
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
excessive back pressure and to prevent water running back
through the pump in case of driver failure on open systems.
Armstrong Flo-Trex valves may be used in place of isolation
valves and non-return check valves. Flo-Trex valves use plug
& disk design which may also be used for throttling excessive
system flow for constant speed pumps and, if necessary, for
variable speed pumps. Do not throttle variable speed pumps
unless absolutely necessary.
note:
Design Envelope 4200h units are accurately aligned at the
factory prior to being shipped and do not need re-aligning
when installed.
Alignment on a Design Envelope 4200h 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 authorized electrician in accordance
with local site regulations and the latest issue of the
iee regulations.
For retrofit applications with multiple pumping units
operating in parallel, the ampacity of conductors,
ratings of switches, branch-circuit, short circuit and
ground-fault protection should be reviewed prior to
installation (Reference nec/nfpa 70 section 430,
or oesc section 28).
Before removing the inverter cover, the system
must be disconnected from the mains supply. After
switching o, wait for at least 15 minutes for the
capacitors to discharge before opening the cover.
caution
High voltage testing (Megging) of the motor/in-
verter may cause damage to the electronic compo-
nents 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 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:
1 Switching frequency
2 Motor grounded on site or not
The leakage current is of importance to safety during han-
dling/operation of the pump if (by mistake) the on-board
inverter has not been grounded.
Since the leakage current is >3.5ma(approx 4-20ma), rein-
forced 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
content (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
connected). This is the preferred method of starting and
stopping 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-temperature protection is required (i.e. thermal over-
loads). 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/284°f), another protection is
provided thought the drive.
a depm ambient temperature de-rating
If the motor is operated at temperatures above 45°c(113°f)
(see motor frames below), a derating of the continuous
output current (or power) is necessary.

b 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.
c 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.
d 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
