OPERATING AND INSTALLATION INSTRUCTIONS SYSTEM VENTECH PKOM4 PAGE 7
The System Ventech PKOM4 type heat
pump combi unit is intended for installation in residential or industrial
buildings. It is a compact ventilation unit
with integrated heat pump module, used
for mechanical aeration and ventilation of rooms and for air conditioning
(heating or cooling). The version with
storage tank will also heat and store the
household hot water supply.
Designated use includes the supply or
extraction of up to 250 m³/h of air.
The heat pump module comprising two
separately operating refrigeration systems will allow heating of the (drinkable)
hot water and simultaneously also heat
or cool the supply air.
The areas supplied with air will be
supplied with filtered and conditioned
fresh air. The extract air from bathroom,
toilet and kitchen will be discharged to
dispose of moisture and odours.
The extracted air must be free of
aggressive vapours and substances
causing wear. Any other use shall be
deemed contrary to designated use. The
manufacturer accepts no responsibility
for damages or consequential damages
arising from improper use.
Designated use shall also include servicing as prescribed in the Operating and
Installation Instructions.
This unit is not intended for use by
persons, including children, with limited
physical, sensory or mental capacity or
who lack experience and/or the requisite
knowledge, unless under the supervision
of a person responsible for their safety
or instructing them on the use of the
unit. The unit is not suited for external
installation and shall only be installed
in suitable and temperature controlled
interior areas. The heat pump combi unit
is not suited for drying and baking out of
new buildings.
The System Ventech PKOM4
type heat pump combi unit is
not a ready-to-use product and
may only be switched on after proper
installation and linking into the ventilation and air conditioning components.
Only qualified and instructed persons
shall work on and with the unit. Persons
transporting, setting up or working on

The safety regulations and
standards must be heeded
when operating the unit in the
presence of room air dependent fireplaces. The supply of air for combustion in
a fireplace must be provided separately
where such fireplace draws on room air.
Proper operation of the PKOM
4
heat
pump unit requires that it must be
possible to shut o existing piping for
combustion air and flue gas systems of
fireplaces drawing in room air.
The PKOM
4
heat pump unit may only be
installed in rooms, homes and user units
of similar size containing fireplaces
drawing in room air provided
safety systems ensure that such fireplaces using liquid or gaseous fuels
cannot be used simultaneously with the
ventilation system of the dwelling or
provided the waste gas ducting for such
fireplaces will be monitored by safety
systems.
If the pressure in the room where the
fireplace is installed is more than 4 Pa
below external pressure, the extract air
system must automatically and safely
switch o.
3.2 REQUIREMENTS FOR OPERATION
WITH FIREPLACES
Due to high loading and irre gular operation, the air ext racted by a kitchen hood must
not be integrated in a home ventilation
system. Two options for operation of a
kitchen hood are possible:
A) The air extracted by kitchen hoods
may be separately discharged to the
atmosphere through exhaust air ducting,
taking into account corresponding inflow
of air (e.g. through window ventilation).
The balance of air volumes in the home
will be disturbed if a kitchen hood is
operated without a separate air supply.
Proper operation of home ventilation
system will thus not be assured (low
pressures, spreading odours, etc.).
B) The kitchen hood operates with circulating air.
The PKOM
4
heat pump combi unit has
been developed and manufactured for
controlled mechanical aeration and
ventilation, with additional heating and
cooling of homes and rooms for similar
use, such as seminar rooms and small
oces. The heating power for household
hot water is designed for average hot
water requirements (nominal usage
profile L as per EN 16147).
Any other use shall be deemed improper
and may cause personal injury or damage to the PKOM
4
heat pump combi unit,
for which the manufacturer shall accept
no liability.
The manufacturer shall accept no liability
for any damages due to:
• Non-observance of the Safety,
Operating and Servicing instructions
in these Operating and Installation
Instructions
• Installation of spare parts not supplied
by the manufacturer, whereby the
responsibility for the use of such spare
parts shall rest with the installer of the
equipment.
• Normal wear and tear
Do not use the PKOM
4
heat pump combi
unit unless in perfect condition and use
only as designated; be aware of safety
issues and potential hazards and familiarise yourself with the notes and information contained in these Instructions.

One device, 4 benefits:
Ventilating – heating – cooling – hot water
The PKOM
4
heat pump combi unit unites these four functions on a footprint of
less than 0.75 m². Controlled ventilation
of living rooms will constantly ensure
fresh and filtered outside air in the
rooms and ensure hygienic exchange of
air. The highly ecient heat recovery
system is also optionally available as a
design with recovery of waste air humi-
dity. To prevent overly high summer
temperatures in the living rooms, heat
recovery may also be bypassed during
cooler night hours by means of a bypass
flap.
We dierentiate between 2 versions:
• PKOM4 classic: Version with household
hot water.
• PKOM4 trend: Version without
household hot water.
6.1 PKOM
4
CLASSIC The PKOM4 classic heat pump combi
unit is the preferred compact overall
solution for passive house construction
homes with up to 130 m² living area. The
volume of household hot water will comfortably provide for a family of 4.
A controlled heat pump will in addition
condition the supply air, i.e. heated or
cooled on demand. Another heat pump is
used for ecient provision of household
hot water. Both heat pumps may be operated in parallel to ensure uninterrupted
provision of air and water.
6.2 PKOM4 TREND Household hot water storage and the
associated heat pump are omitted in the
PKOM
4
trend unit version. The PKOM4
trend heat pump combi unit is the best
alternative to conventional living room
ventilation units. The supply air into the
living rooms will be cooled and dehumidified during summer, as needed. The
supplied air will be heated in the colder
months.

Clean and hygienic air filters are a prerequisite to high quality air. Unserviced
or poorly serviced filters significantly
aect living comfort and increase power
consumption of the fans. Heavily soiled
filters may cause faults and malfunctions of the heat pump combi unit.
The condition of the air filters
must be checked regularly!
When must filters be replaced?
In your own interest you should check
and replace the filters regularly. The
extent of soiling of the filters varies
depending on location, ambient and

15. Protecting the counterflow heat exchanger from freezing
15.1 HOT GAS PRE-HEATING
BATTERY
Medium to serious frost will in winter pose a danger of freezing in the
counterflow heat exchanger, depending also on the humidity and temperature of the extract air. The
minimum values of external temperature for proper operation will differ, depending on the type of heat
exchanger. At temperatures lower
than these, the heat exchanger
should be protected by taking suitable precautions.
Minimum fresh air temperature for
apparatus type S (standard heat
exchanger): -3°C
Minimum fresh air temperature
for apparatus type F (enthalpy heat
exchanger): -7°C
The standard configuration of heat
pump combi equipment is with a hot
gas pre-heating battery positioned
in the counterflow heat exchanger
directly at the fresh air inlet. The
temperature of the incoming fresh
air is monitored by a temperature
sensor between the hot gas preheating battery and the counterflow
heat exchanger. If this temperature is lower than the defined minimum temperature, the fresh air will
be warmed up by routing hot gas
from heat exchanger circulation HK
through the pre-heating battery.
Pre-heating fresh air via
the heat pump will reduce
the available supply air
heating capacity. The shortfall in
heating energy must be provided
through external means.
15.2 GEOTHERMAL HEAT
EXCHANGER
Highly eective frost protection may
be achieved by incorporating a geothermal heat exchanger in the ventilation system.
Note the following when implementing a geothermal heat exchanger:
• The system must be buried using
watertight piping down to frostfree depths, taking into account
that the system must be accessible for cleaning.
• The manufacturer’s installation
guidelines must be followed.
• Condensate drainage must be pro-
vided.
• Ensure that moisture will not be
allowed to penetrate through the
air ducting apertures in outside
walls.
• To avoid frost damage, lay to
ensure adequate spacing from
other structural components such
as water pipes, foundations, etc.
• Do not use geothermal heat
exchangers if the soil is contaminated.
• To ensure energy eciency and
air hygiene, geothermal heat
exchangers must be carefully
planned and implemented.

16. System extension with auxiliary heating
16.1 DUCT HEATING BATTERY
The heat pump combi unit will
already provide a passive house
with a large part of its required
heating and cooling power. Supplementary heating may be necessary
during lengthy periods of negative
outside temperatures.
The duct heating battery will be installed in the supply air duct. Should
the heat pump not be able to supply
the supply air at the required temperature, the duct heating battery
will switch on automatically. The
heating power will in this case be
continuously controlled up to 1200
W heating.
This type of operation requires an
external temperature sensor in the
air duct after the duct heating battery, connected to the main PC
board.
