2.4 Installation
The ultracool units must always operate with the panels closed to
enable the inlet of fresh air only through the condensor.
If the operation of the ultracool unit is with ambient temperatures below
5ºC (41ºF), ethylene glycol must be added to the water of the
installation. The ethylene glycol concentration is obtained according to
the following chart.
Ambient temperature ºC (ºF) 5(41) -5(23) -15(5)
% Ethylene glycol 10 20 30
The ethylene glycol percentage is given as % measured as weight of the
total mixture.
In the case of any modification in the quantity of water in the installation,
the concentration of ethylene glycol should be checked.
Do not use automotive antifreeze. Use lab grade ethylene glycol or
refrifluid only! Do not use an ethylene glycol concentration above
the 30%; this would damage the water pump.
