Caution
The glycol must be without additives and auto glycol must not be used.
Automatic bleeding has to be installed at the highest point of the 2 pipes — supply or return pipe
G.3.4 Electrical connection of components and functions
Cables are numbered for appropriate termination for internal and external connections. These numbers can also be found on the wiring
diagram.
G.4 Installation – Pipes for water – hot and chilled, valves and drains
G.4.1 Description
If ordered with the unit, the valves and valve motors are stored in a carton box placed inside the unit. Water traps are the responsibility
of the installer and are necessary to ensure the escape of water from the drain pan where applicable. Proper trap sizing procedures must
be followed during installation.
G.4.2 Pipe connections
Connection pipes on heating and cooling coils are provided with external thread. Drainage outlets on drip trays are provided with
external thread.
G.4.3 Hydronic coil freeze protection
Care needs to be taken with Hydronic Coils to prevent water from freezing. Failure to do so could result in equipment/property damage
not covered by the unit warranty. If subjected to below freezing conditions control solutions must be implemented.
The typical control method involves an Auto Reset Capillary Type switch to turn off the unit if an abnormal drop in discharge air

temperature reading. Depending on the application and coil surface area, multiple sensors may be used in series.
If no control method is used, be sure to apply best practices in addition to properly draining the coil prior to exposure to freezing
conditions.
G.4.4 Pipe connections to coils
G.4.4.1 Heating coils
Pipes for hot water must be protected by insulation against frost and loss of heat. Pipes, insulation, control system for heating wires and
circulation pump are not delivered by Systemair.
G.4.4.2 Cooling coils
If ordered with the unit, the valves and valve motors are stored in a carton box placed inside the unit. Pipes for cooling must be
protected by insulation against condensation on the pipes and loss of cooling in the summer. Pipes and insulation are not delivered by
Systemair.
G.4.4.3 Rigid pipe mounting brackets for valves, circulation pumps and pipe system
The coil and pipes from the coil are not constructed to withstand the weight and stress from valves, circulation pumps, long pipes and
insulationofpipes.Thesystemmustbesupportedcarefullyinrigidpipemountingbracketstoroof,oorandwalls.
