Installation of Filter / Strainer is mandatory for water system. The Filter or Strainer shall be located in front of inlet pipe of PHE.
While operating the system, some dust and foreign materials can circulate the system and can make the whole system not
work well due to blockage of heat exchangers and corrosion in some components.
Filter mesh : #50
Piping insulation
The complete water circuit, inclusive all piping, must be insulated to prevent condensation during cooling operation and
reduction of the heating and cooling capacity as well as prevention of freezing of the outside water piping during winter
time. The thickness of the sealing materials must be at least 9 mm with (0.035 W/mK) in order to prevent freezing on the
outside water piping.
If the temperature is higher than 30°C and the humidity is higher than RH 80%, then the thickness of the sealing materials
should be at least 20 mm in order to avoid condensation on the surface of the sealing.
