5. Preparations
5.1. Installation
 Place the unit on an even surface on a pad made of non-flammable
material.
 Cooling machine, pump motor and electronics produce intrinsic heat that
is dissipated via the venting openings! Never cover these openings!
 Keep at least 20 cm of open space on the front and rear venting grids.
 The place of installation should be large enough and provide sufficient
air ventilation to ensure the room does not warm up excessively because
of the heat the instrument rejects to the environment. (Max. permissible
ambient temperature: 40 °C).
For a fault (leakage) in the refrigeration system, the standard EN 378
prescribes a certain room space to be available for each kg of
refrigerant.
The refrigerant quantity is specified on the type plate.
> > For 0.25 kg of refrigerant R134a, a room space of 1 m
3
is required.
 Do not set up the unit in the immediate vicinity of heat sources and do
not expose to sun light
 Before operating the unit after transport, wait about one hour after setting
it up. This will allow any oil that has accumulated laterally during
transport to flow back down thus ensuring maximum cooling
performance of the compressor.
The bath cover (1) is mounted on the bath tank with 4 captive screws (2).
Required tool: SW3 hexagonal socket wrench with ball-shaped head
The circulating pump transports the
bath fluid to the temperature chamber
(4) at the bottom (3). The overflow on
top of the chamber ensures a constant
fluid level during operation.
The bath cover (5) provides 6
measuring places (6) that can be fitted
with different Viton
® sleeves..
