HANDLING AND INSTALLATION
- Unpack the unit close to the installation area.
- Inspect the unit to make sure there is no apparent damage.
- 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
- Clamp and insulate both glycol lines to the pump outlet and to the unit return fitting.
- Clean the reservoir.
- Fill the reservoir with CBS propylene glycol solution (mixed 2 parts water to 1 part glycol).
- Place the cover on the unit.
- Plug the pump in the electrical box on the unit.
- Plug the unit to an appropriate electrical circuit. This task should be executed by a professional electrician in compliance with national electrical standards.
- Inspect the unit for any leakage.
- 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
- Remove the upper deck from the unit.
- Clean the reservoir and remove any dust or contaminant.
- Connect the overflow fitting to a proper external reservoir or drain.
- Clamp and insulate both glycol lines to the pump outlet and to the unit return fitting. Repeat this step for each pump.
- Fill the reservoir with CBS propylene glycol solution (mixed 2 parts water to 1 part glycol).
- Place back the upper deck on the unit.
- 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.
- Inspect the unit for any leakage.
- 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
- Check the glycol level each month to make sure it’s still within 0.5 inch below the overflow fitting.
- If the level is too low, add CBS propylene glycol solution (mixed 2 parts water to 1 part glycol).
- 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.
- Drain and replace the propylene glycol solution every 24 months.
- Clean the condenser every thirty (30) days. Be careful to not damage the aluminum fins. NEVER brush sideways.

TROUBLESHOOTING
OBSERVATION | CAUSE | FIX |
---|---|---|
Compressor doesn’t start | Temperature controller or relay failure (temperature | |
controller housing) | Check the output voltage on each components (2) and |
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.
