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 necessary to use glycol additionally or assure the reversible heating
agent temperature more than 25 °C.
Pipework package must include circulation pump, which circulates

heating/cooling medium through the coil (smaller circuit) and 3-way
mixing valve with modulated 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.
