Name and Shape 2.2. Special tools for R410A refrigerant Tool name Gauge manifold Contents of change Pressure is high and cannot be measured with a conventional (R22) gauge. To prevent erroneous mixing of other refrigerants, the diameter of each port has been changed. It is recommended the gauge with seals -30 inHg to 768 psi (-0.1 to 5.3 MPa) for high pressure. -30 inHg to 551 psi (-0.1 to 3.8 MPa) for low pressure.
EMBEDDING THE INDOOR UNIT IN A WALL 4. ELECTRICAL REQUIREMENT The indoor unit is powered from the outdoor unit or branch box. Do not power indoor unit from separate power source. WARNING Refer to local codes for acceptable cable type. 5. SELECTING THE INSTALLATION LOCATION • When installing a grating, use a grating with narrow upper and lower horizontal bars so that the airflow from the upper and lower air outlets does not contact the bars.
