4.4 Installation
After transportation, let the unit stand in its intended working position for six hours. This
is to allow the oil to drain to the bottom of the compressor. This is normal procedure for
refrigeration compressors. Allow at least 100mm clearance from obstructions on all
sides so that there is free air flow through the unit, from the front to the back (this also
has the advantage that air is not blowing directly out of the sides onto instruments next to
the LTC4).
Place the unit a level, non-combustible surface. Ensure that the mains plug and
the switch at the rear of the unit are easily accessible.
If the equipment has been transported or stored in cold or humid conditions,
condensation may form inside it. If that could have happened, allow time (at
least 2 hours at room temperature) for the condensation to evaporate before
using the equipment.
Do not block or restrict ventilation slots.
Do not connect to a power supply or switch on before filling the tank.
Drain before moving the unit. Before draining allow the liquid to cool below
50˚C.
Do not touch the condenser fins, they are sharp and may cause injury.

Electrical supply
Connect the LTC4 to a grounded (earthed) electrical power supply with voltage
and frequency within the range specified on the serial number plate.
The LTC4 must only be connected to the mains using the mains cord supplied
or one with an identical rating (see section 9.4)
Ensure the mains switch and isolating device (power supply connector) are
easily accessible during use.
