With split ring
NOTE: The unit will not lift or lower when it is in charging position.
No split ring
To begin the transferring procedure: 1) Install the patient sling around the patient. See “Use of Slings” section in this manual for further information. 2) Move the ceiling lift directly over the patient. Use the LEFT and RIGHT buttons on the handset (see Fig. 5).
Fig. 7
5) To lift the patient, press the UP button. 6) Make sure the patient is clear of any obstacles before moving him/her. Guide the patient’s legs if necessary. 7) When the patient is located above the desired point of transfer, press the DOWN button. 8) Use the handles on the back of the sling to position the patient when transferring into a chair. Hold the handle firmly as the sling will tilt back to position the patient. 9) Once the patient is properly seated and the straps have slackened, remove the sling from around the patient, and off the ceiling lift. 10) Move the ceiling lift away from the patient. 11) When the V10 is no longer required, return the ceiling lift back to the charging station. The charging indicator light on the clip-on charging station must be on for the ceiling lift to detect it.
3) Use the DOWN button on the handset to lower the spreader bar to a point below the chin of the patient (to avoid the risk of it striking the patient’s face due to a sudden movement). If the patient is lying down, lower the spreader bar down near the patient’s thorax, then install the straps.
WARNING: Hold the ceiling lift spreader bar with one hand at all times when near a patient. 4) Attach the straps to the desired position. See “Use of Slings” section.
Verify the green light on the charger station and the amber light (flashing or solid) on the ceiling lift to ensure that the charging function is working properly.
15
How to Use the V10 Ceiling Lift
CAUTION: Do not pull the red emergency cord with excessive force. If the cord is jerked too hard, the ceiling lift may become inoperable.
NOTE: The V10 is equipped with a safety system to prevent a misuse of the ceiling lift. If the lift is used above the amount specified by the duty cycle, a heat detection system will signal the processor to block the lifting of a load until the temperature of the transmission cools down. In the meantime, it will still be possible to activate the horizontal displacement and down functions. When the overheat protection is engaged, the red light will stay on during the cooling period. In addition, a buzzer will sound if the UP button is pressed. The cooling period is between 10 to 30 minutes depending on ambient conditions.
2) To reactivate the ceiling lift, pull the red cord gently once. A green light confirms that the V10 is on and ready for use.
Emergency Lowering In the unlikely event of an electrical failure, the V10 has an emergency manual lowering feature. CAUTION: The Emergency lowering feature is to be used only in case of emergency. If the ceiling lift malfunctions when a patient is being transferred, the emergency lowering device provides a safe way of getting the patient down onto a chair, bed or wheelchair (see Fig. 8). To use it:
Return to Charge (RTC) The RTC function is disabled by default. To activate this function, please refer to the “V10 Programming” section in this manual.
1) Pull the red emergency cord. 2) Remove the little black cap located on each side of the lift.
To engage the RTC function, press on the return to charge button on the handset for 3 seconds. The spreader bar will raise all the way up to avoid any obstacles during the run. When the lift is at the charging station, the spreader bar lowers by itself to the preselected height so as to be easily accessible.
3) Find the 8 mm Allen key that came with the ceiling lift. Insert the Allen key deep into the axle. Turn it counterclockwise in order to lower the patient. Each turn of the key will slowly lower the patient. Repeat on the other side of the lift.
NOTE: You can stop the return to charge at any time by pressing any button on the handset or pulling on the red emergency cord. Moreover, a weight detector prevents the RTC from functioning while a person is in the lift.
4
Emergency Stop (red cord)
Emergency Brake
The emergency stop can be activated at any time to stop the functioning of the ceiling lift.
The emergency brake is an additional safety feature that automatically prevents the patient from falling in the unlikely event that of a transmission or motor failure.
Turn the Allen key counter-clockwise to slowly lower the patient. Repeat on the other side of the lift.
Once the patient is lowered and secure within a chair, bed or wheelchair, call a qualified technician to inspect the ceiling lift.
1) To stop the ceiling lift in any emergency, gently pull the red emergency cord once, until you hear a “click” (see Fig. 4 in the “Part Designation” section of this manual).

How to Use the V10 Ceiling Lift Battery Information
Indicator Lights
The life cycle (number of charging cycles) of the batteries is largely dependent on the depth of discharge within each cycle. The more the batteries are drained, the shorter their overall life span. The life of the batteries is also related to such factors as varying temperatures and rest periods between when they are charged and discharged.
The ceiling lift and the charging system have many indicator lights. It is important to understand their significance for the proper use and comprehension of the ceiling lift (see Fig. 10).
Charging the Batteries WARNING: Do not operate the charger unit with a damaged cord or if the unit has been dropped or damaged. Do not bend the power cord by force, or place a heavy object on it. This will damage the cord and may cause fire or electrical shock.
NOTE: To prolong battery life, return the ceiling lift to the charger whenever the ceiling lift is not in use. If the low battery indicator beeps, and a green light flashes, be sure to recharge the batteries as soon as possible. Charge the batteries until the charging indicator light is a solid amber before using the lift again. This will extend the life of the batteries.
The steps for recharging the batteries are as follows: 1) Press the return to charge button on the handset. A protection device prevents the ceiling lift from returning to the charger if a patient is in the ceiling lift during this operation.
NOTE: BHM Medical uses sealed lead-acid batteries. These batteries do not have any memory effect. Therefore, batteries should not be completely drained before recharging.
2) The green indicator light will begin flashing if batteries are low and need to be recharged. If the light does not turn on, verify the “Troubleshooting” section of this manual. 3) The amber indicator light will flash when the ceiling lift cassette has returned to the charger and the batteries are being charged. Once the charge is complete the light will stop flashing and become a solid amber light.
CAUTION: Never leave a ceiling lift with the power on for an extended period of time without returning it to the charger. The batteries will be drained and damaged.
WARNING: Batteries need to be charged for a minimum of 8 hours prior to the initial use of the lift.
See Fig. 9 for a graph illustrating the relationship between the number of lifts versus the load being lifted.

How to Use the V10 Ceiling Lift Use of Slings
If the batteries have been completely drained it could take up to 6-8 hours to completely recharge them. In order to reduce the charging time, refrain from completely draining the batteries and leave the ceiling lift on the charging station between uses.
Spreader Bar WARNING: The V10 comes with a fourhook spreader bar and must be used only with BHM bariatric slings, as indicated in the list of accessories.
Programming the Ceiling Lift The V10 can be programmed so that the user can easily adjust the speed of the horizontal movement, the spreader bar height and the return to charge parameters of the ceiling lift. To learn about the programming mode, see the “V10 Programming Guide” on pages 25-27 of this manual.
WARNING: Spreader bars must only be installed by a qualified person.
WARNING: Before using the V10, always ensure the strap attachment pin is installed correctly through the spreader bar socket and lift strap, and that the split ring is correctly inserted through the hole in the pin (see Fig. 7).
Using the FIDO Function (Pre-Programmed Positions)
Before Approaching the Patient Attendants should always tell the patient what they are about to do. Make sure to have on hand a sling that is of the correct model and of adequate size for transfer with the V10 unit.
WARNING: This function can only be activated by a qualified technician. 1) Using the pre-programmed positions allows the unit to detect stations (positions) located along the track path. The unit will go to the indicated position by using the handset.
To Lift a Patient from a Bed WARNING: When transferring a patient from a bed, have caregivers on each side of it, or raise the bed rails to ensure the patient does not roll off the bed.
2) To do so, indicate to the unit the desired position to go to. For an example, to go to the third station push three times on the PROG button followed by the direction (LEFT or RIGHT buttons).
1) Position the patient onto the sling, by rolling the patient towards you then folding the sling in half and placing it behind the patients back, so that the bottom edge of the sling is aligned with the bottom of the patient’s spine (see Fig. 11 and Fig. 12).
Then the unit will go by itself to the requested station and stay on hold there. If the position you asked for is not correct, you may stop the ceiling lift at any time by pressing any button on the handset. From this position, reprogram the ceiling lift to the new desired position. Count the number of stations from where you are and indicate the direction to go.
2) Position the sling carefully so that when rolled back the patient will lie centrally on the sling. Check that the head support area of the sling is also in position. With heavy patients the use of a slide sheet is recommended.
