See Fig. 7.Drip trayReplaceable plate heat exchangers involve a riskof leakage.It is recommended to take this into account whileinstalling. Preferably install a drip tray underneaththe heat exchanger to prevent leakages onto thefloor and/or harm to electrical equipment.Screen plateIf the heat exchanger is being used withtemperatures above 60 °C or with aggressivefluids, we advise that you cover the heatexchanger with a screen plate to prevent the riskof human exposure to the surface and fluids.If storing the plate heat exchanger for a longerperiod of time, i.e. more than one month/30days, the following precautions should be takento prevent unnecessary equipment damage:Preferably the plate heat exchanger should bestored inside in dry conditions at roomtemperatures around 15 – 20 °C (59 – 68 °F) anda humidity of maximum 70%.If this is not possibly, place the plate heatexchanger in a wooden box provided with alining on the inside that will prevent againstmoisture penetration.Rubber gasket material is sensitive to certainagents and ultraviolet radiation.• Plate heat exchangers must be storedin rooms with no ozone producingequipment such as electric motors orarc-welding equipment as ozone maydestroy several rubber materials• Plate heat exchangers should not bestored together with any organicsolvents or acids in the room• Do not expose the plate heat exchangerto ultraviolet radiationFig. 7.
