I.3.5 Lock the doors by using the key
Use the key to lock the doors. The doors are not locked
automatically by turning the handle to the vertical
position.
I.4 Installation – Pipes for water – hot and chilled, valves and drains
I.4.1 Description
If ordered with the unit, the valves and valve motors are stored in a carton box placed inside the unit. Water trap(s) –
standard or optional - is (are) necessary to ensure escape of water from the tray under plate heat exchanger and (or)
cooling coil. Water trap(s) is (are) stored in a carton box placed inside the unit.
I.4.2 Pipe connections
Connection pipes on heating- and cooling coils are provided with external thread. Drainage outlets on drip trays are pro-
vided with straight pipe for quick connect fittings on the pipe with the water trap.
I.4.3 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.
I.4.4 Pipe connections to batteries
I.4.4.1 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.
I.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 insula-
tion are not delivered by Systemair.
I.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 insulation of pipes. The system must be supported carefully in rigid pipe mounting brackets to roof, floor
and walls.
I.4.4.3.1 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
output |
