Ultra 1.54
Comfortable indoor climate in high-end interiors
Installation and operating instructions
1.2 Limits of use for cooling
Due to its generously dimensioned basic construction and low basic fan
speeds, the cooling model is fundamentally used with air dehumidification.
Nevertheless, specific operating modes and settings need to be taken into
account for cooling mode:
• Never move the louvre slats into the end positions, e.g. to shut off
a discharge opening. In particular at high fan speeds, there is a risk
that water droplets could be carried into the other air outlet fields by
inadmissibly high air speeds.
• Only operate the following units at a maximum fan speed of 680 rpm:
• EC design: type 963133 / type 964133
• Three-phase model: type 963136 / type 964136
• Single-phase model: type 963116 / type 964116
• Refer also to the table in chapter 5 “Technical data”.
• To prevent impermissibly severe cooling down of the housing when
the fan is at a standstill, we would recommend the use of valves (e.g.
thermoelectric shut-off valve with recirculating mode).
This counteracts the outer parts of the housing from experiencing
condensation, especially with extreme conditions involving very high
levels of humidity.
1.3 Condensation pump
The self-priming condensation pump is fixed to the hose connector for the
on-site condensation pressurised line.
This ultra-quiet, electromagnetically operating pump is mounted together
with the upstream condensation filter on the upper side of the unit.
Max. delivery height: 8 m with max. 4.5 l/h flow rate and a hose length of
10 m
Max. pump volume: approx. 18 l/h with 0.5 m delivery height and a hose
length of 2 m
Supply voltage: 230 V/50 Hz (separate power line needed)
Power consumption: 14 W
Condensation pressure line: DN 6 mm (hose connection)

1.54 Ultra
Comfortable indoor climate in high-end interiors
Installation and operating instructions
1.3.1 Connecting the condensation pump
1.3.2 Limits of use of the condensation pump
The achievable flow volume of the condensation pump used depends on
the delivery height and length of condensation hose connected. The volume
of condensation rises and the possible delivery height of the pump falls
with extreme air humidity and/or very low system temperatures. Particularly
when operating larger Ultra models (Series 96), the volume of condensation
produced can exceed the permitted pump volume under extreme conditions.
Therefore set up the alarm contact on the float switch so that dehumidification
is stopped (e.g. by closing the cooling valve).
Note the following limits of use of the condensation pump for the
max. permitted cooling conditions (CHW 6/10 °C at entering air temp.
27 °C / 60 % rel. humidity):
Ultra series 85: max. permitted delivery height with a 5 m hose length: 3 m
Ultra series 96: max. permitted delivery height with a 5 m hose length: 2 m
Precise limits of use for the respective operating modes can be calculated
using the calculation program at www.kampmann.de/ultra/calculation.
Higher-performance pumps are available on request if higher condensation
volumes than the maximum permissible have to be discharged.

Installation and operating instructions
2. Safety information
Only allow a qualified electrician to perform installation, assembly and
maintenance work on electrical units in compliance with VDE guidelines. The
connection should comply with the applicable VDE regulations and provisions
laid down by the regional electricity providers.
Non-compliance with the regulations and operating instructions can result in the
units malfunctioning with consequential damage and danger to people. There is
a danger of fatal injury caused by wires being crossed due to incorrect wiring!
Regularly check the unit heater’s electrical equipment. Immediately replace loose
connections and faulty cables.
Disconnect all parts of the system from the mains power supply and prevent
them from being reconnected before starting any connection and maintenance
work!
EC fan
Electrical loading (>50 C) between the mains conductor and protective
conductor after switching off the mains power supply when switching several
fans in parallel.
• Ensure that a contact safety device is fitted. The mains connections and PE
need to be shorted before working on the electrics.
The terminals and connectors are still energised even when the unit is
switched off. Check whether the terminals and connectors are de-energised
with a two-pin voltage tester.
• Only open the unit 5 minutes after all poles of the voltage have been switched
off.
The earth wire carries high leakage currents (depending on the frequency,
intermediate voltage and motor capacity). Therefore check EN-compliant
earthing under test conditions (EN 50 178, art. 5.2.11). Hazardous voltage can
occur at the motor housing without earthing.
In the event of a fault, electrical voltage will be produced at the rotor and
impeller. Rotor and impeller are base-insulated.
• Do not touch when fitted!
The fan runs when control voltage is applied or the stored fan speed starts up
automatically when mains power fails.
• Do not go near the hazard area of the unit.
High temperatures occur at the fan’s electronic housing.
• Combustion hazard.
The fan is protected from blockage. Protective functions are integrated
depending on the fan type, which cause the fan to switch off automatically in
the event of diverse faults.
• Please refer to the operating instructions for the respective fan for further
information!
Please read these instructions in full to ensure correct and proper installation and
the correct operation of Ultra unit heaters.

Detail of screw opening
6.2 Filter assembly
• Fit the filter, if provided as an accessory, once all
electrical work has been completed, the water
connections have been made and the condensation
pump connected.
• The instructions for fitting the filter hood can be
found in separate installation instructions. Simple
filter attachments with a ring are simply placed
over the motor guard. Then fit the air intake
crown.
6.3 Installation of the air intake crown
Caution! Only fit the air intake crown once all
connection and installation work has been completed.
The terminal box, valves, motor guard, condensation
pump etc. can no longer be accessed once the air
intake crown has been fitted.
The air intake crown is supplied as standard and
serves as an intake grille with recirculation air units,
and as a casing and mixed air units. When the Ultra
is fitted directly onto a solid ceiling and pipes are run
under the ceiling, the air intake crown cannot be
fitted as intended. In this case, it can optionally either
be omitted entirely or adapted on site, for instance by
removing partial segments of the grille.
Before fitting, first loosely connect the individual
sections to each other. Once fitted, they become
more stable on the Ultra base plate.
Caution! The air intake crown sections may
have sharp edges! Risk of injury!
• First screw one of the screws provided into the
screw hole provided on each of the six sections
(2nd opening from the bottom, see detailed
diagram).
• Insert 2 individual parts of the intake crown
together and screw them together through the
2nd bottom opening in the louvre.
• Then place the sections in the appropriate position
on the base plate of the Ultra (see diagram on
page 13 or the drilling template on the cardboard
packaging). The louvres should be pointing
downwards!
• Then screw the sections to each other by tightening
each screw.
Caution! Make sure that the gap between the ceiling
and the air intake crown is maintained and not filled
by subsequent work on the ceiling, such as plastering,
to ensure that it is possible to subsequently remove
the air intake crown.

7. Waterside connection
• Connect the Ultra as per the labels on the product.
• Route the pipes so that no mechanical stresses are transferred to the heat
exchanger and the unit can be accessed with ease for maintenance and
repair work.
• Provide ventilation for the pipes on site.
• Properly seal pipe connections not being used.
• Important note: The heat exchanger is suitable for use with hot water
heating systems in compliance with DIN 18380. Ensure that operating
conditions and water quality conform to VDI 2035 and comply with
industry-standard installation regulations.
Caution! Hold the connections on the heat exchanger with a pipe wrench
or other suitable tool when connecting the pipework.
Caution! Insulate all pipes with an impermeable material on cooling units!
Continue the insulation through as far as the unit.
Caution! The use of flexible pipes (such as braided pipe connections,
spiral or corrugated pipes) are recommended in particular when installing
the unit under a solid ceiling. When used in conjunction with appropriate
shut-off valves, it is then possible to dismantle the unit relatively easily
without needing to dismantle the fan. EC fans can only be replaced if the
entire Ultra has been dismantled.

1.54 Ultra
Comfortable indoor climate in high-end interiors
Installation and operating instructions
9. Installation of condensation drain (with Ultra for cooling)
9.1 Routing the condensation lines
Note the following when routing the condensation lines:
• Condensation collection lines should have an appropriately sized inner
diameter.
• Make sure that they are routed with a gradient towards a free outlet.
Please refer to the separate instructions for the condensation pump for
more information on maintenance, delivery height etc.
9.2 Connecting the condensation pump
Ultra units for cooling are fitted with a condensation tray to collect
condensation from the air drawn in. This is drawn off by the condensation
pump and discharged along a hose connected on the pressure side.
Depending on conditions on site, the water can be discharged into drainage
lines, possibly with a trap connection. A float switch monitors the water level
and switches the pump off if it is exceeded (refer to separate instructions).
The condensation is drained off. An alarm contact is triggered in the event
of a malfunction of the condensation drain.
9.2.1 Ultra without fitted KaControl module, recirculation air
We would recommend automatically terminating cooling operation when
the maximum condensation level is reached to prevent the condensation
tray from overflowing.

Comfortable indoor climate in high-end interiors
Installation and operating instructions
9.3 Electrical connections
• The condensation pump is fixed to the top of the unit with a rubber pad
and can be simply removed for installation and cabling work.
• Connect the voltage supply and alarm contact (separate cable with plug)
as per the wiring diagram on page 17 (only with Ultra without KaControl
module, recirculation air).
• Then connect the 6 mm-diameter hose (provided on site) to the
condensation drain on the vent valve (see diagram on left) and secure in
place with cable ties.
9.4 Commissioning and functional testing of the condensation
pump
• Switch on the mains voltage.
• Pour water into the condensation tray. The pump should switch on
automatically and switch itself off again.
• Test the alarm switch: add water until the alarm switch is triggered
(acoustic or visual warning message fan switches off or similar).
9.5 Warning information/Technical data on condensation
pump
• Check the float switch with the coarse screen regularly and clean if
necessary.
• Regularly check the condensation drain.
• Refer to the technical literature on the condensation pump.
• Refer to chapter 1.3, pages 7-8, for technical data and limits of use.
Caution!
In the initial phase of cooling, it is possible that a white film forms in the
condensation tray, mainly on the outer edge. This is simply residue from the
protective layer in the heat exchanger and can simply be wiped away with
a cloth.
Connect a hose here and secure with
cable ties!

10. Electrical wiring
10.1 Safety information
The electrical wiring of this products requires technical knowledge of
electrical engineering. This knowledge, generally learned in vocational
training in one of the fields stated, is not described separately here. Errors
with the wiring can lead to the unit being damaged! The manufacturer is
not liable for any damage to people and materials caused by the wrong
wiring and/or improper handling. Note the following safety information
before starting to work on the controller and on the Ultra:
• Regularly check the unit heater’s electrical equipment. Immediately
replace loose connections and faulty cables.
• Disconnect the system and ensure that it cannot be accidentally
reconnected.
• Only use the wiring diagrams enclosed to carry out the electrical
connection.
• Only wire the unit in accordance with currently applicable VDE and EN
guidelines, as well as Technical Wiring Regulations stipulated by the
regional energy supply companies.
• Only connect the unit to fixed wiring.
• The operator of the unit is responsible for the EMC conformity of the
entire system in accordance with the local applicable standards.
EC fan
Electrical loading (>50 C) between the mains conductor and protective
conductor after switching off the mains power supply when switching
several fans in parallel.
• Ensure that a contact safety device is fitted. The mains connections and
PE need to be shorted before working on the electrics.
The terminals and connectors are still energised even when the unit is
switched off. Check whether the terminals and connectors are de-energised
with a two-pin voltage tester.
• Only open the unit 5 minutes after all poles of the voltage have been
switched off.
The earth wire carries high leakage currents (depending on the frequency,
intermediate voltage and motor capacity). Therefore check EN-compliant
earthing under test conditions (EN 50 178, Art. 5.2.11). Hazardous voltage
can occur at the motor housing without earthing.
In the event of a fault, electrical voltage will occur at the rotor and impeller.
Rotor and impeller are base-insulated.
• Do not touch when fitted!

1.54 Ultra
Comfortable indoor climate in high-end interiors
Installation and operating instructions
The fan runs when control voltage is applied or the stored fan speed starts
up automatically when mains power fails.
• Do not go near the hazard area of the unit.
High temperatures are produced at the fan’s electronic housing.
• Combustion hazard.
The fan is protected from blockage. Protective functions are integrated
depending on the fan type, which cause the fan to switch off automatically
in the event of diverse faults.
• Please refer to the operating instructions for the respective fan for further
information!
Please read these instructions in full to ensure correct and proper installation
and the correct operation of Ultra unit heaters.
10.2 Motor protection
10.2.1 AC fans
Thermal contacts (temperature monitors) are embedded in the motor
windings, which open when the maximum winding temperature of
155 °C is exceeded. The motor is switched off whenever it impermissibly
heats up combined with an appropriate protective switch. The motor is thus
protected against overload operation, over- and undervoltage, unacceptably
high ambient temperature and the rotor jamming.
Thermal contacts meet the conditions for protecting against overloading
of equipment with electric motor drive (VDE 0730). Commercial motor
protection switch or bi-metal trips are not suitable as motor protection
with multi-stage operated motors. Only appropriately wired controllers or
modules or a similar type of switch may be used.
Single-phase controller
The thermal contacts lock the motor via the single-phase controller each
time the motor heats up inadmissibly.
Continuously variable power module type ... V
The thermal switch off the motor via the stage switch each time the motor
heats up inadmissibly (without locking the motor!). A potential-free NC
contact offers the option to lock the 0-10 V control signal to “0 V” by
means of an on-site controller.
The unit is not short circuit-proof! The device will not work if the motor
cable short circuits. Even when the motor is idle, the motor cables (U1 and
U2) are still carrying mains potential!
