Notes
- Do not allow pressure higher than the airtightness pressure to be applied to the expansion valve when checking the airtightness of the piping.
- When using the R410A-compatible valve in a heat pump circuit, install the thermal sensing bulb and external equalizing tube between the 4-way valve and the accumulator (at the inlet side of the compressor).
- The R407C-compatible valve is designed on the basis of an R22-compatible obsolete model, so its values may differ slightly from those listed.
- For mounting the thermal sensing bulb, see installation tips.
