4. Pipe system
The plumbing work must be carried out by an authorised plumber.
The pipe system that connects the cooling and heating coils and exchanger must be
equipped with a pump, regulating and monitoring equipment.
The pipe system must be protected from frost damage via a built-in control system,
which opens the valve for water flow, stops the fan and closes the damper against
outdoor air if there is a risk of frost damage.
A sensor must be fitted on the return water pipes.
The pipes should be insulated in consideration of the actual temperature conditions in
and around the system.
Important: When installing outside, the motor valve must be protected against
penetrating water.
Liquid (water/glycol) is connected to the spigots that run out through the side of the air
handling unit.
Heating, cooling and exchanger coils consist of copper pipes with aluminium fins, which
are fitted in a steel plate frame. Supply and return flow occurs in collecting pipes with
connection spigots that run out through the side panel.
The collecting pipes are equipped with a spigot for air screw and a spigot for draining.
• Remember to hold extra counter force on the collecting pipe when connecting
the coil to the pipe system.
• The thread must be packed in accordance with standard plumbing regulations.
• The supply flow should always be connected to the bottom spigot.
