Installation - Refrigeration Hoses
IMPORTANT: All hose bends must maintain at least minimum bend radii with no kinks. See “Minimum Bend Radii” on page 35.
Condenser Module Connections
1. Liquid Line
• Fabricate #6 hose from liquid line fitting on condenser module to
drier in refrigeration module.
• Install female 90°, male 90° ORS fittings with O-rings and tighten
securely.
2. Discharge Line
• Fabricate #8 hose from discharge fitting on condenser module to oil
separator fitting in refrigeration module.
• Install female 90°, male 90° ORS fitting with O-rings and tighten
securely.
Evaporator Connections
3. Suction Line - REMOTE (Fresh Compartment)
• Fabricate #16 hose from manifold fitting A to the large suction
fitting of the accumulator assembly on REMOTE evaporator.
IMPORTANT: The suction line for the REMOTE evaporator must
be attached only to manifold fitting A or severe damage to the
compressor will result!
