CAUTION
To prevent personal injury, carefully connect and disconnect
manifold gauge hoses. Escaping liquid refrigerant can cause
burns. Do not vent refrigerant into the atmosphere. Recover all
refrigerant during system repair and before final unit disposal.
1. Purge gauge lines. Connect service gauge manifold to
base-valve service ports. Run system at least 10 min-
utes to allow pressure to stabilize.
2. Temporarily install thermometer on suction (large) line
near suction line service valve with adequate contact and
insulate for best possible reading.
3. Refer to the superheat table provided for proper system
superheat. Add charge to lower superheat or recover
charge to raise superheat.
4. Disconnect manifold set, installation is complete.
Superheat Formula = Suct. Line Temp. - Sat. Suct. Temp.
HIGH VOLTAGE!
Disconnect ALL power before servicing.
Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.
