Self-priming Seawater Pump WB200
2) Seawater cooling exits:
Provide for a separate seawater exit for each air conditioning unit
installed even if only one pump provides cooling for all units. Introduce shut-off valves for each unit if
1 pump provides cooling for more than 1 air conditioning unit. This will allow easy priming of the
circuit and also calibration of the seawater flow for each air conditioning unit in case of imbalance in
the water tubing lengths.
3) Evaporator coils:
The finned coils of the evaporators and/or air-handlers are fragile. If the fins are
damaged during installation, take care to re-align them to ensure proper air-flow.
4) Air-ducts:
Flexible air-ducts need to be of good quality with sufficiently strong steel or plastic
reinforcement. Do not restrict air flow by bending the air-ducts too tightly or by accidental local
deformation. Do not install air ducts of excessive lengths (> 2.5 m); the pressure loss and consequent
reduction of air-flow will seriously diminish the efficiency of the installation.
