Connection of exchangers
When connecting heating or cooling supplies the forces
originating at fitting dilatation and its weights may not be
transmitted to the unit. Appropriate places of connection
are marked on panels of section (heating water inlet
(outlet), coolant inlet (outlet), condensate outlet).
To reach maximal output it is necessary to connect the
exchangers in the counterflow direction. When con-
necting the fittings to the exchangers it is necessary to
use two wrenches during the drawing close to prevent
twisting off of the connection of the exchanger collec-
tors.
Warning: After connection of water exchangers (hea-
ters and coolers, including mixing sets) to the system
it´s necessary to do aeration (irrigation) and deaeration
of the whole circuit, including exchangers and check
tightness of pipe connections and of the exchanger
itself (including inspection of section with water exchan-
ger). Producer of unit does not take over guarantees for
damages caused by fluid leak from connections or by
damaged exchanger.

Water exchangers

As standard, the water heat exchangers are equipped
with automatic Taco 1/2" air-venting valves, which are
situated on the upper parts of both headers.

Steam humidification
For a detailed description of installation, commissioning
and prescribed inspections of the steam humidification
section, refer to the separate manual which is a part of
the accompanying documentation of the FP air-handling
unit. When installing the steam humidification section,
observe the following recommendations:
Air ducts leading through cold areas must be insu-

from quiet areas.
100°C heavily mineralized water is drained from

the steam humidifier.
The following minimum distances (distances

between the steam tube and the following air-hand-
ling unit components, where H represents the mini-
mum evaporating distance calculated for the given
conditions) must be observed to ensure proper
operation of the steam humidifier:
