    Note
    Install the desiccant filter slide hammer, and then tap the filter inwards to allow enough clearance to remove the snap ring.
  6. Remove the desiccant filter from the Supermanifold.
  7. If the desiccant filter is being replaced, weigh the desiccant filter, and record the oil weight. Skip this step if the filter is being reused.
    1. Zero out the scale and set measuring units to G.
    2. Weigh the desiccant filter and record the measured weight.
    3. Locate the dry weight marked on desiccant filter.
    4. Subtract the marked dry weight from the measured weight, and then record the difference to be used in oil balancing at a later step.
      • Example: Measured weight (185g) - dry weight (169.272g) = 15.728g difference. Add an additional 15.7g of oil to system when returning recovered oil during charging.

Install

  1. Lubricate the O-rings on the desiccant filter with fresh refrigerant oil before installation.
  2. Install the desiccant filter into the Supermanifold with the tap pointing upwards, and then gently tap the filter into place with a slide hammer.
