23) When the chiller is within the operating conditions set by the manufacturer, check whether the current uptake
of the chiller agrees with the data indicated on the identification plate and with those contained in the table in
the supplement.
Controller Type "C", see 6.4 (CHW 682 to CHW 1252)
1) Remove the front plate and the two side panels.
2) Open the tank cap and fill the tank (using a T-fitting if necessary) while watching the level indicator (refer to
Fig. 1, Point 5.2.1).
3) Open the filler screw on the pump head.
4) Tighten the screw again when only cooling medium flows out.
5) Open the shut-off valve.
6) Open the switch cabinet with the key supplied (Fastened to the main switch when the chiller is delivered).
7) Ensure that the motor protection switches ("MTC" and "MTP") are in position "0".
8) Fill the tank to the maximum (upper arrow, level indicator is located on the bottom right of the frame). See
Section 6.1.1 (Water requirements).
9) Move the motor protection switches "MTC" and "MTP" to position "1".
10) Make sure that the water is able to circulate adequately. It the circuit might be interrupted by something such
as a valve, electrical valve, a filter or anything else, a by-pass circuit (automatic overflow valve) must be in-
stalled in order to prevent damage to the pump.
11) Lock the switch cabinet with the key.
12) Move the main switch of the chiller to position "1" (the temperature of the cooling medium appears on the
display).
Never touch any part of the cooling medium circuit when the chiller is running!
13) Start up the chiller by pressing the
14) Because the pump starts up immediately, make sure that the direction of rotation for the pump matches the
direction of the arrow on the casing. If it is rotating in the opposite direction, turn off the main switch of the
chiller immediately and arrange for the polarity of the chiller to be reversed.
15) After a few minutes carefully open the filler screw again in order to remove any residual air. Tighten the screw
again afterwards.
16) Wait until the chiller has attained the operating conditions; this is indicated when the display shows the preset
working range.
17) Check whether the pressure shown is within the limits specified for the pump. If not, take appropriate action
to ensure that pump is running within the specified limits.
18) Check the level in the tank and top up with cooling medium if required. Fasten the tank cap afterwards.
19) Wait for the compressor to switch on. The compressor symbol will appear on the display (see Section 6.4).
20) Check the inside of the chiller and the piping system for leakage or loose connections.
21) Fit the front panel and the two side panels back onto the casing.
22) Check the preset target value. The chiller is normally factory-set to the temperature required by the custom-
er.
23) When the chiller is within the operating conditions set by the manufacturer, check whether the current uptake
of the chiller agrees with the data indicated on the identification plate and with those contained in the table in
the supplement.
