6. Maintenance
6.1 General | Warning! Always disconnect MultiTemp III from the mains |
| (Pull out the mains plug) before maintenance and/or service. |
| Service should be carried out by authorised personnel only. |
| To maintain efficient operation of the compressor cooling |
| unit, have the air grid and liquifier (heat exchanger) checked |
| and cleaned by service personnel two to four times a year, |
| depending on the amount of dust in the air. |
| Always ensure the liquid bath has sufficient circulating liqu- |
| id. |
| The cooling coil in the bath and the bath vessel itself should |
| be periodically checked and any deposits removed. Metal |
| particles and acidic or alkaline substances should be removed |
| quickly as they could harm the stainless steel material and |
| cause corrosion. |
| After some time, the stainless steel surface and the housing |
| may show spots and become tarnished. Clean them with |
| stainless steel liquid cleaners normally used in the kitchen. |
| Do not use scouring pads or powder! |
| Disposal |
| MultiTemp III will provide many years of efficient operation. |
| When its working life is over, however, please remember that |
| the unit contains coolant R 134a, which despite its environ- |
| mental friendliness may only be discarded by authorised per- |
| sonnel. |
