Cooling Water Flow Distribution Monifolds
       
Proper water flow is absolutely critical to the operation of the SeaMach™ reverse cycle air conditioner.  If the pipe is to small, back pressure is created causing a drop in water flow, even if the pump is correctly sized.  If the piping is to large, the slow velocity of the water may cause silt build-up and barnacle growth inside the piping, eventually restricting water flow.




Condensate Drains

MAS-CDH16            ⅝"        Condensate Drain Hose per meter





Condensate Drains
(Applies to all self contained units and the air handler section of all units)

The stainless steel base pan has multiple openings for condensate drains.  It is highly recommended that two of the openings be utilised, one for back-up in case the other becomes clogged or blocked.  The other openings should be sealed and plugged. The SeaMach™ reverse cycle air conditioner can produce significant quantities of condensate that may cause extensive damage to the vessel if not disposed of properly

A. Select the two openings that will NOT be used for the condensate lines.

B. Plug and seal them

C. Install the condensate drains fittings through the base pan.  Make sure the fittings are water tight.

D. Attach a ⅝" ID reinforced hose to the hose barb and secure with two stainless steel hose clamps.

E. Route the condensate hose down from the SeaMach™ reverse cycle air conditioner to a sump or to an overboard fitting.  If the drain runs overboard, it must not be within three (3) feet from the exhaust from the engine or generator.  Double Clamp all connections.

F. If the condensate lines are run through a room or compartment containing engine or fossil fuelled devices, it is imperative that the line be air tight to prevent carbon monoxide or any other hazardous gasses or vapours from being introduced into the conditioned system.
