16| SAHP - BMTB Installation Manual
V1 Mar 2019US - SD667052
5.13 Ensure that refrigeration quality copper pipes only are used
to connect the Thermodynamic Panel to the BMTB. It must
also be ensured all refrigeration pipework is insulated
 withexibleanti-condensationinsulation.
NOTE: Direct contact between the refrigeration outlet and
refrigeration inlet line shall be avoided to prevent energy losses in
the system.
NOTE: Ensure the BMTB liquid outlet is connected to the
Thermodynamic Panel liquid inlet, and the BMTB suction side is
connected to the Thermodynamic Panel gas outlet.
NOTE: Do not loosen or open service ports until all connections are
made and the system has been fully leak checked and vacuumed.
NOTE: Do not Cover the brass plate nuts with the anti-vibration
insulation as this may create a freeze / thaw action on the brass which
may result in the are nut braking down over time.
5.14 Nitrogen Pressure Test
First pressure test the refrigeration circuit with Oxygen Free
 Nitrogen.Nitrogencanbeintroducedusingtheserviceport
