4.3. Heating coil connection

Pipe work should be connected in accordance with good engineering practice. All pipe work must
be adequatelysupported to ensure that no additional load is stressing the unit. Mounting the pipes on
the heating coil, tight the pipes with spanners. As shown in 16 Picture.

The pipe work should be done in order to ensure the space for maintenance and service work. When
carrying out the installation of heater pipes, make sure that hot water supply is completely disconnected.
Before start-up of the air handling unit, the heater system should be filled in with water. Glycol is used in
the air handling units with coil heat exchanger. Never pour glycol down a drain; collect it in a receptacle
and leave it at a recycling centre or the like. Glycol is highly dangerous to consume and can cause fatal
poisoning or damage the kidneys. Contact a doctor! Avoid breathing glycol vapour in confined spaces. If
you get glycol in your eyes, fush them thoroughly with water (for about 5 minutes).
When operating air handling unit in the temperatures lower than 0 °C, it is neces-
sary to use glycol additionally or assure the reversible heating agent temperature
more than 25 °C.

lated actuator. In cases if 2-way valve is used, additionally it must be installed non-
return valves to ensure continuous circulation around smaller circuit. PPU must be
installed as close to the water coil as possible.
It is important to maintain air heaters and coolers cleanliness; that is to change
filters installed in the air handling unit on time. If the air heater or cooler gets dirty,
to perform periodical cleaning.
