J.3.3 Possibility of extracting components from the unit
Pipes and cables must not obstruct the inspection doors and components which can be extracted from the unit. Poten-
tial components for extraction are filters, fans and rotary heat exchanger.
J.3.4 Pipe connections to batteries
J.3.4.1 Heating coils
Pipes for hot water must be protected by insulation against frost and loss of heat. Further protection against frost can
be obtained by installing electrical heating wires around the pipes and under the insulation combined with temperature
sensors and a control system. Pipes, insulation, electrical heating wires, control system for heating wires and circulation
pump are not delivered by Systemair.
J.3.4.2 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 insula-
tion are not delivered by Systemair.
J.3.4.3 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 insulation of pipes. The system must be supported carefully in rigid pipe mounting brackets to roof, floor
and walls.
J.3.4.3.1 Pipe connection to heating coils
The heating capacity of the coil with only 2 rows is independent of the connection of the hot water in equal flow or in
counter flow to the direction of the air, but connection of the hot water to the pipe marked for inlet and the return
water to the pipe marked for outlet is very important to ensure that the sensor for transmission of the water tempera-
ture really will be placed in a return circuit of the coil (Screw-joint for the water temperature sensor is welded in the
main collection pipe for return water).
For the frost protection of heating coil, the water temperature in the coil is transmitted to the controller The controller
always generates a signal to the valve motor that keeps a sufficient flow of hot water to protect the coil against frost.
This frost protection is also activated when the running mode is “off”.
Coils with 3 rows or more must always be connected in counter flow to the airflow.
Note:
If glycol is added, 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.
If the heating battery is built with 3 or more rows, the water flow must be in counter flow to the direction of the air.
