Installation
After transportation, let the equipment 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 at the front and rear so that there is
free air flow through the equipment.
Place the equipment on a firm, level surface. Ensure that the mains plug and
the switch at the rear of the equipment are easily accessible.
After transport or storage in humid conditions, always allow the equipment to
stand for at least an hour at room temperature before operating.
Do not block or restrict ventilation slots. Allow at least 100mm clearance from
obstructions
Do not connect to a power supply or switch on before filling the tank.
Drain before moving the equipment. Liquid to be drained should not be below
10°C or above 50°C.
Always operate the equipment with the condenser grille fitted.
4.4
Rotating the heating circulator
The heating circulator is fitted ready to use with the pump ports facing the left-hand side.
If required, the heating circulator can be rotated so the pump ports face the rear and the
user controls are accessed from the left hand side.
Consider rotating the heating circulator, if following a risk assessment, access to hot
surfaces needs to be reduced.
To rotate, remove the thumbscrew at the rear of the refrigerated bath and lift up the
heating circulator and top plate. Remove the 2 thumbscrews from the underside of the
top plate to release the heating circulator. Rotate the heating circulator on the top plate
and refit.
4.5
Fitting the communications lead
Connect the communications lead from the heating circulator to the refrigerated bath.
The connecting ports are shown in Section 4.2.1 (Figure 2), and 4.2.2 (figures 4 & 5).
This enables the heating circulator to control the cooling power. If the lead is not
connected correctly, the heating circulator
will display the fault ‘Check the refrigeration
unit’.
4.6
Electrical supply
Connect the equipment to a grounded (earthed) electrical power supply with
voltage and frequency within the range specified on the serial number plate.
