LABEC LHF-80 - Manual (Page 2)

Introduction
Congratulations on the choice of an Australian made quality product. Labec products are
manufactured, tested and calibrated to meet published standard specifications under our strict
quality assurance guidelines.
This Instruction Manual is for the guidance of operators of Labec Water Baths and should be read
before the water bath is connected to the electricity supply.
It is hoped that this manual will supply all the information that the customer should require for
satisfactory operation of the water bath. If, however, there are any questions that remain
unanswered then the customer should contact our Service Department.
Unpacking
Remove all packing and protective wrapping from both interior and exterior of the water bath. Check
the water bath for any possible transit damage. Ensure all ordered accessories are present. If any
physical damage or shortages are evident, do not discard the packaging material until the water
bath is inspected by the distributor, agent or manufacturer.
NOTE: All claims for shortage or damage must be made within fourteen days (14) from
delivery.
Subject to our standard published conditions of sale, we have reasonable grounds to believe that we
have ensured, so far as is reasonably practical, that the products listed in our catalogue and
brochures have been designed and constructed so as to be safe and without risk to health when
properly installed and used in their environment by appropriate and trained personnel, and where
applicable, in accordance with our published instructions.
Installation
Electrical
This equipment must be tagged and tested according to AS/NZS3760:2010 prior to use and
thereafter on a regular basis dependent upon the environment.
It is preferable to locate the bath close to a power point and recommended that double adaptors are
not used. Check the total wattage if connecting to multi­point outlets. Check the rating plate for
power requirements. Installation is to be carried out by a qualified electrician in accordance with the
power requirements of the product specifications. Ensure the unit is Tag Tested prior to first
power up.
Location
Select a location free from draught and away from direct sunlight or other heat source.
Circulating Pump
If a circulating pump is fitted there will be two small holes at the end of the bath. The upper hole is
the inlet and sucks the water in and then pushes it out the lower outlet hole across the heating
elements under the tray. Ensure before the bath is ever turned on that the upper inlet holes is well
covered at all times. Test the water pump is circulating with your finger and if not you will need to
push some water into the inlet hole using a hose or similar to push the airlock out of the pump
system.
Temperature Control
LABEC water baths are fitted with either simmerstat/thermostat controls or temperature controller
as per Appendix A, connected to the element. The water bath has been stringently tested before
shipment to ensure all is in working order.
