Installation - Mechanical
coupling and tighten securely by turning the hex nut, on the fitting body
only.
CAUTION
Equipment Damage!
Do not tighten the clamping nut at this time. This will prevent
proper sensor insertion.
3. Insert the sensor into the compression fitting (through the clamping nut)
until the plastic coating on the sensor contacts the top of the clamping
nut.
4. Use a wrench to carefully tighten the clamping nut until the sensor can
no longer be turned by hand.
5. Scribe a reference line can the clamping nut at the "six o'clock" position.
Then, while observing the reference point, tighten the nut 1-1/4 additional
turns.

Refrigerant Relief Valve Venting

Condenser Pressure Relief Valve Venting (for RTWA units only)
All RTWA units utilize a refrigerant-pressure relief valve for each circuit which
must be vented to the outdoor atmosphere. The valves are located at the top
of the condenser. When facing the control panel, Circuit #1 relief valve is
approximately 5" left of center and Circuit #2 relief valve is approximately 5"
right of center. Relief valve connections are 5/8" flare. See Figure
Table 5. Refer to local codes for relief valve vent line sizing requirements.
NOTE: Vent line length must not exceed code recommendations. If the line
length will exceed code recommendations for the outlet size of the valve,
install a vent line of the next larger pipe size.
