General information about the JUMBO HomeThe JUMBO Home (in short CBJ-Home) is a specially developed solution for patient lifts. The complete
system consists of a control box and a battery enclosed in a single elegant module. The CBJ-Home is
medically approved and contains a series of features ensuring a safe comfortable lift, e.g. the CBJHome is equipped with a soft-start function, emergency lowering, emergency stop etc.
The CBJ-Home-batteries are ventilated through a number of ventilation holes on the rear of thehousing.
Mounting of CBJ-Home (only vertically)

UPDownBattery information:
Prior to first use of the batteries
Prior to first use of the batteries, please make sure that they are charged 24 hours in order to reachproper function and prolong the lifetime of the batteries.
Maintenance of batteries
For an optimum lifetime the product must be charged as often as possible.
The batteries must be charged at least every 3rd month - otherwise they will be damaged due to selfdischarge. It is recommended to test the battery function at least once every year.
The batteries are to be replaced after approximately 4 years or earlier, dependent on the pattern ofuse. Frequent and high-powered discharges reduce the battery life.
Authorised replacement of battery
Only an authorised LINAK service centre or a properly trained customer should change the battery ina CBJ-Home. If a CBJ-Home is opened and a battery changed by an unauthorised person there is arisk that it may malfunction at a later date.
Tamper proof
As of Q4, 2017, LINAK has introduced a security label fortamper proof. The use of the security label makes it easier to see
if batteries have been replaced by non-authorized persons.
The labels consist of a polyester clear film with special void
effect and follow the contours of the control box. Onceapplied to the substrate sun removal, an irreversible and dry“void” footprint message will detach itself from the face film.
Labels which have been removed cannot be reapplied since
repositioning will leave visible proof that the product has
been opened.

Types of batteries that can be used for replacement
The batteries must only be replaced by the same type of batteries (LINAK A/S part number BA0CBJH00 (2batteries with 1 wireharness)) or mechanical and electrical equivalent types: 12V, 2.9 AH, 99 x 56 x 79 mm(L x W x H).
The batteries must be new or maintained by means of charging at least every 3rd month. Thebatteries, which make a set, must be supplied with identical production codes. Mismatching ofproduction codes may lead to a severely reduced battery life.
Before mounting ensure that the battery set is correctly connected and check that no connectors areloose.
Warranty and battery life
If any batteries built into LINAK products are, within a period of 12 months from the production of theLINAK product as stipulated on the product label, found to be defective, LINAK® will provide a newproduct. This applies only so far as the products have been used and maintained correctly and have notbeen tampered with and the systems is unopened. Furthermore, the products must not be exposed toviolent treatment. LINAK explicitly disclaims all other remedies. All LINAK products are designed to havean optimum lifetime, but the expected lifetime in a specific application is very dependent on how theproducts are used.
Further information on LINAK warranty can be found on the LINAK website www.linak.com/warranty.
