OPERATING AND INSTALLATION INSTRUCTIONS SYSTEM VENTECH PKOM4PAGE 8
The safety regulations and
standards must be heeded
when operating the unit in the
presence of room air dependent firepla-
ces. The supply of air for combustion in
a fireplace must be provided separately
where such fireplace draws on room air.
Proper operation of the PKOM4heat
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 PKOM4heat 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 fire-
places 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 circu-
lating air.
The PKOM4heat 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 dama-
ge to the PKOM4heat 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 PKOM4heat pump combi
unit unless in perfect condition and use
only as designated; be aware of safety
issues and potential hazards and famili-
arise yourself with the notes and infor-
mation contained in these Instructions.
