General information 

 

Before Installation 

 

 

On receipt of the product, all items should be visually inspected and any damage or shortage should be advised to the supplier 
immediately. 

 

Ensure that the correct voltage supply is available for the unit requirement. Damage to electrical components within the unit will 
occur if this is not observed. 

 

Check that the proposed equipment location is suitable and provides adequate support for the weight of the unit. 

 

Check the proposed equipment location for mains services (gas, electric water etc.) before drilling holes for ventilation duct and 
unit fixings. 

 

If using external ducting arrangement, ensure ducting route will fall within the limitation of pressure resistance as noted on page 
6. 

 
 
 
 

During Installation and subsequent maintenance 

 

 

Installation and maintenance are to be performed only by qualified personnel who are familiar with local codes and 
regulations, and experienced with this type of equipment. 

 

If lifting equipment is required, ensure that it is suitable for purpose, certificated and that the operatives are qualified to use it. 

 

Safe working methods are identified and operatives have suitable Personal Protective Equipment (PPE). 

 

Ensure the working area is clear of obstructions. 

 

The units contain moving parts and electrical power hazards, which may cause severe injury or death. Disconnect and shut off 
power before installation or service of the equipment. 

 

Units must be earthed. 

 

The electrical covers and fan guards must remain fitted at all times. 

 

Use of the units outside of the design conditions and the application for which the units were intended may be unsafe and be 
detrimental to the units, regardless of short or long term operation. 

 

The units are not designed to withstand loads or stresses from other equipment or personnel. Such extraneous loads or stress 
may cause failure or injury. 

 
 

Important Note: 

 
Only qualified and authorized personnel, who are familiar with refrigeration systems and components 
including all controls, should perform the installation and start-up of this equipment. To avoid potential 
injury,  use  care  when  working  around  sharp  edges  of  metal  cabinets.  All  electrical  wiring  should  be 
installed  in  accordance  with  all  applicable  codes,  ordinances  and  local  by-laws.  No  work  should  be 
undertaken on any equipment without first ensuring 

all 

electrical supplies are isolated.  

 

Please  be  aware  that  during  operation,  even  if  the  JABC  unit  is  electrically  isolated  at  its  own 
supply, there may be terminals within it which are still LIVE. Ensure that the source of the supply is 
also isolated before attempting any service or maintenance operations.
