6�1� REFRIGERANT LEAKAGE DETECTION
NOTES AND METHOD
Refrigerant leak detection is prohibited in closed area.
An ignition source must not be used during leak
detection.
Leak detection fluids can be used but the use of
detergents containing chlorine must be avoided as
the chlorine may react with the refrigerant and cause
corrosion.
Completely de-gas the refrigerant from the heat pump
before any brazing is carried out. Brazing must only be
carried out by trained technicians in accordance with
EU517/2014.
If a refrigerant leak is suspected stop using the heat
pump and contact Dantherm Group UK service,

6�2� INITIAL CHECKS
Start the filtration pump before the heat pump is
switched on, and turn off the heat pump before the
filtration pump.
Note. Heat pump must be turned off prior to
backwashing.
Before staring the heat pump, please check for any
leakage of water; and set the required temperature on
the thermostat, and then switch on power supply.
In order to protect the swimming pool heater, the
machine is equipped with a time lag starting function.
When starting, the fan will run for one minute before
the compressor starts, and when power to the
machine is turned off it will stop running one minute
after the compressor stops.
After starting up, please check for any abnormal noise
from the machine.
