3. Verify bin thermostat capillary tube is mounted correctly (Fig. 6).
4. Run tube from dispenser to icemaker, and cut to length.
Note:
Tubes
may
NOT
have dips, may
NOT
have bends of less than 6" (153mm) radius,
and
may
NOT
have splices/joints.
5. Cut insulation off tube where tube enters grommet.
6. Slide end of tube without insulation through grommet and run to evaporator port.
7. Install a section of insulation on tube from grommet to evaporator port.
8. Slip supplied hose clamp over free end of tube.
9. Pull insulation back from free end of tube.
10. Push tube on evaporator port.
11. Position clamp behind lip on evaporator port and tighten clamp.
12. Connect bin thermostat twist-lock cord to dispenser plug.
Install refrigeration line
Note:
The installer of the refrigeration line set must be USA Government-Environmental Protection Agency
(EPA) certified in proper refrigerant handling and servicing procedures.
A qualified person must perform all roof or wall penetration.
Do not form unwanted traps in refrigeration lines. A service loop is not considered an oil trap.
Never coil excess refrigeration tubing.
The compressor oil rapidly absorbs moisture. Minimize the exposure of the refrigeration system by
not releasing the condenser unit or evaporator unit holding charge until all line connections are
finished and the system is ready for evacuation.
To prevent oxidation of the copper, purge line set and condenser unit with dry nitrogen while brazing.
For lines longer than fifty feet, add one additional pound of R404A refrigerant for every 25 feet of line run
up to 100 feet (see refrigeration charge table). Consult factory for line runs beyond 100 feet.
It is recommended that both liquid and suction lines are run and insulated together for the first 15
feet from the condensing unit. This protects the system from sub-cooling loss and/or liquid slugging
the
compressor.
