Never use silicone oil with silicone tubing.
Pumping heat transfer liquid around an external system can lead to hazards that are
outside the control of Grant Instruments. It is essential that the user conducts a risk
assessment of the entire equipment installation to ensure that correctly rated materials
have been used throughout and that the system can be used safely.
5.1.4 Emptying the LTC2
The LTC2 tanks should be emptied to a safe level prior to moving. A drain tap is
included to allow convenient emptying. See section 5.2.3 for full details.
Allow the liquid temperature to fall below 50˚C before emptying.
5.1.5 Setting up and switching on
Follow instructions in section 5.1.3 to attach the pump connector plate and insulated
hose. Before filling and switching on, attach the open end of the hose to the application,
taking care to note the inlet and outlet.
Ensure all hoses are connected securely. Liquid will begin pumping
immediately once the LTC2 is switched on.
Add the appropriate working liquid to the bath to at least the minimum recommended fill
level such that the float level switch is fully raised.
The control unit can be powered either from the mains supply directly or via the cooler
unit (230V units only). An interconnect cable can be used to supply power from the
mains socket outlet on the rear of the cooler unit to the control unit (see Section 5.2.4).
Plug the mains cable into the fused power inlet socket on the rear of the refrigeration
unit.
Switch on the LTC2 control unit using the power switch on the rear. The motor will start
immediately and the buzzer will sound while the unit starts up. Switch on the
refrigeration unit using the power switch on the front of the unit. The LTC2 will start to
control at the set temperature.
