Installation Procedures

Install the sensor according to the procedures b elow.
(1) Turn off the power of the unit, and remove the top panel, bottom panel, and control box cover.
(2) Remove the lid of the service port on the service valve (liquid side for Y series or high-pressure side for R2 series), and install the medium
pressure sensor assembly 㽲 as shown in Figure 1 (to the tightening torque of 20± 2N䊶m).
Apply some sealing material (ThreeBond 1110D, field-supplied) to the service port screws to keep water out of the screw part.
Screw down the mount ing plate of the m edium pressure sensor with the fixing screw on the left side of the refrigerant service valve, which can
be found either on the gas side (Y series) or on the low-pressure side (R2 series).
*At the completion of installation, check for a refrigerant gas leak.

in the control box.
Fix the cables in place with the cable strap behind the f rame at the bottom of the control box, just as with the cables of the sensors on the unit.
*Watch for static electricity when connecting connectors. (Static electricity can damage them.)
*Check that 63HS2 can be monitored from t he Maintenance Tool.
(4) Remove the function setting connector that is connected to CNTYP4 on the Main board in the control box. (Figure 2)
Insert the strap on the function setting connector (enclosed part 㽳 or 㽴) into the hole on the right side of the control box, and t hen connect the
connector to CNTYP4. Remove the existing function setting connector to prevent it from being misused. (Cut the strap with a nipper if the strap
does not come off.)
(5) Attach the label (㽵), which has the cautionary notes on rep lacing the circu it board, to the control box cover. (Figure 3)
(6) Replace the top panel, bottom p anel, and control box cover.
