3.4 - WATER CONNECTIONS
3.4.1 - Water connections - Evaporator/Condenser
The water circulating pump will be preferably installed upstream so that the evaporator/condenser will be subjected
to positive pressure. Entering and leaving water connections are indicated on the certified drawing sent with the unit
or shown in the sales brochure.
For shell and tube heat exchangers, a drainage plug is located at the base of the evaporator. A drainage pipe may
be connected to this to enable drainage of evaporator water for service operations or for seasonal shut down.
The use of a water filter in the water circuit upstream of the heat exchanger is mandatory. These filters must remove
all particles with a diameter greater than 1 mm, and must be positioned within 1 meter of the inlet of the exchanger.
They may be supplied as an option by the manufacturer.
LACK OF FILTER AT THE INLET OF A PLATE HEAT EXCHANGER WILL MAKE WARRANTY VOID.
Hydraulic drawings in Annexes page 50 to 54, or supplied with the unit.
3.4.2 - Water analysis
The water must be analysed; the water circuit installed must include all items necessary for treatment of the water : filters,
additives, intermediate exchangers, bleed valves, vents, isolating valves etc... according to the results of the analysis.
We do not advise operation of the units with open loops which can cause problems with oxygenation, nor
operation with untreated ground water.
Use of untreated or improperly treated water can cause deposits of scale, algae and sludge or cause corrosion and
erosion. It is advisable to call in a qualified water treatment specialist to determine what kind of treatment will be
necessary. The manufacturer cannot accept liability for damage caused by the use of untreated or improperly
treated water, salt water or brine.
