HANDLING AND INSTALLATION

1. Unpack the unit close to the installation area.
2. Inspect the unit to make sure there is no apparent damage.
3. Cautiously position the unit into the wanted position. Two(2) person are required to lift the unit.

NOTE: Do not move the unit without lifting it. Damage could occur to the legs of the unit if pushed.

NOTE: Do not lift any unit by the refrigeration lines or components. Please use designated handles.

NOTE: For BEF 075, the shroud must be removed to access the lifting handles. Make sure that the shroud is properly secured once the placement is completed.

PLACEMENT

• It is not advised to place a power pack on top of a walk-in cooler.
• It is not advised to place a power pack outside without protections.
• Always make sure a minimum clearance of 24 inches around and above the power pack. This is necessary for proper air flow and servicing.
• Ambient temperature ranges from 60°F to 85°F for all models.
• Make sure the unit is installed in a properly ventilated area.
• Unit must be connected to a ground fault circuit breaker.
• Power pack and pump must have their own dedicated electrical circuit.

BEF-02 INSTALLATION

1. Clamp and insulate both glycol lines to the pump outlet and to the unit return fitting.
2. Clean the reservoir.
3. Fill the reservoir with CBS propylene glycol solution (mixed 2 parts water to 1 part glycol).
4. Place the cover on the unit.
5. Plug the pump in the electrical box on the unit.
6. Plug the unit to an appropriate electrical circuit. This task should be executed by a professional electrician in compliance with national electrical standards.
7. Inspect the unit for any leakage.
8. Glycol temperature should be adjusted to 27°F. Set point should be reached within a few hours

NOTE: To adjust the glycol temperature, please see section 2.4.

BEF-04, BEF-05 AND BEF-075 INSTALLATION

1. Remove the upper deck from the unit.
2. Clean the reservoir and remove any dust or contaminant.
3. Connect the overflow fitting to a proper external reservoir or drain.
4. Clamp and insulate both glycol lines to the pump outlet and to the unit return fitting. Repeat this step for each pump.
5. Fill the reservoir with CBS propylene glycol solution (mixed 2 parts water to 1 part glycol).
6. Place back the upper deck on the unit.
7. Plug the unit and the pump to an appropriate electrical circuit. This task should be executed by a professional electrician in compliance with national electrical standards.
8. Inspect the unit for any leakage.
9. Glycol temperature should be adjusted to 27°F. Set point should be reached within a few hours.

NOTE: To adjust the glycol temperature, please see section 2.4.

ADJUSTING THE TEMPERATURE CONTROLLER

Instructions for all models

MAINTENANCE

1. Check the glycol level each month to make sure it’s still within 0.5 inch below the overflow fitting.
2. If the level is too low, add CBS propylene glycol solution (mixed 2 parts water to 1 part glycol).
3. If there are any signs of ice in the unit, give time to the ice to melt and change all the solution with a fresh solution mixed as indicated in the installation instructions.
4. Drain and replace the propylene glycol solution every 24 months.
5. Clean the condenser every thirty (30) days. Be careful to not damage the aluminum fins. NEVER brush sideways.

TROUBLESHOOTING

replace thedefective part
Relay, overload or start capacitor failure (on the compressor)| Replace relay and/or overload and/or start capacitor
Input voltage is too low| Check input voltage, refer to specifications of the unit
Compressor failure| Replace compressor (Has to be performed by a certified refrigerationexpert)
Compressor runs but never reaches set point| Set point is too low| Adjust set point to a minimum of 27°F
Temperature probe is not properly connected or installed| Temperature probe must be in the bottom of the reservoir and in no contact with any metallic part
Refrigerant leak| Perform a leak test and repair the leak. Vacuum flush the refrigerant and fill with proper quantity. (Has to beperformed by a certified refrigeration expert)
Dirty condenser| Disconnect the unit. Clean the condenser using degreaser and water.Do not spill liquid on any electrical component. Be careful to not damage the aluminum fins of the condenser.
Dusty condenser| Disconnect the unit. Clean the condenser with pressurized air.
Condenser fan malfunction| If the compressor runs but not the fan, replace the fan motor.
Frozen glycol| Inadequate water/glycol mixture| Check mixture with a refractometer. Mixture must be between 5°F and 20°F
Compressor never stops due to malfunction of the temperature controller| Check if temperature probe is properly connected, if required replace temperature controller
No outflow of the circulation line| Circulation line blocked| Inspect and locate blockage. Clean the lines.
Pump failure| Replace the pump
Damper coupling broken| Replace damper coupling

ELECTRICAL WIRING DIAGRAMS

NEVER modify the electrical circuit of the unit. If required, ONLY use 14 AWG wire. Electrical repairs must be done by a professional electrician.
