Tightening
• Connect the refrigerant pipes, from the outdoor unit, to the Hydro Unit as shown below.
• Align the flare connection on each pipe with the corresponding outlet connection on the Hydro Unit.
Tighten the flare nuts, using fingers, to secure the pipes in place.
• Tighten the flare nuts, using a torque wrench, to the tightening torques shown below:
• To prevent damage, to the refrigerant pipes, use two spanners to tighten the flare nut connections to the required
torque.
Water Pipe
WARNING
• Install water pipes according to the regulations of respective countries.
• Install water pipes in a freeze-free place.
• Make sure that water pipes have sufficient pressure resistance.
The setting value of the pressure relief valve is 0.3 MPa.
CAUTION
• Do not use zinc plated water pipes. When steel pipes are used, insulate both ends of the pipes.
• The water to be used must meet the water quality standard specified in EN directive 98/83 EC.
