Guidelines for
Installation of Discharge Hosing
ENG
IN ORDER TO FULLY UNDERSTAND THE OPERATION OF THESE PUMPS, IT IS NECESSARY TO
UNDERSTAND SOME OF THEIR BASIC PRINCIPLES OF OPERATION:
All minisplit piston pumps share some common characteristics:
1. They are self priming.
2. They are water cooled.
3. They are water lubricated.
This means that when they are activated, they will self prime, however during this initial period they will draw in air
and while this is happening they will be running both hot and dry.
Because of this, they will emit a clicking noise which is entirely normal during the initial start up phase
only, (usually around 10 seconds or less) and this will stop when all of the air in the pump intake has been purged
and the pump becomes cooled and lubricated by the water flowing through it.
IF THE CLICKING NOISE IS HEARD WHILE THE PUMP IS OPERATING AFTER THE INITIAL START UP HAS BEEN
COMPLETED, THIS IS AN ABNORMAL SITUATION WHICH INDICATES THAT THERE IS A PROBLEM AND THE
PUMP IS RUNNING WITHOUT COOLING OR LUBRICATION AND IS OVERHEATING.
This usually occurs in a split pump because the intake hose (¼" clear vinyl hose between the reservoir and the pump)
has emptied itself due to a siphoning effect created by atmospheric pressure.
THEREFORE IT IS VITAL THAT THE INTAKE HOSE IS KEPT FULL OF WATER AT ALL TIMES SO THAT NO AIR IS PRESENT
FOR THE PUMP TO DRAW IN WHEN IT STARTS OPERATING.
AS LONG AS THE INTAKE HOSE REMAINS FULL OF WATER, EVERY TIME THE PUMP STARTS UP IT IS IMMEDIATELY
COOLED AND LUBRICATED BY THE WATER FLOWING THROUGH IT AND WILL OPERATE AS DESIGNED, WITH
MINIMAL NOISE.
EACH PUMP IS FITTED WITH A THERMAL OVERLOAD PROTECTOR WHICH WILL DEACTIVATE IT IN CASE OF
OVERHEATING, HOWEVER, ONCE IT COOLS DOWN IT WILL BEGIN TO OPERATE AGAIN, AND IF THE PUMP IS
ALLOWED TO CONTINUE TO OPERATE FOR A SUSTAINED PERIOD OF TIME IN THIS CONDITION, IT WILL FAIL.
In some applications, the vertical distance between the reservoir and the pump can be up to 6 feet and the longer
this distance, the longer the pump will have to operate hot and dry before it evacuates the air from the intake tube
and, therefore, the longer time it will have in which to damage itself.
If the end of the discharge hose is lower than the level of the drain pain in the evaporator, the weight of the water in
the discharge hose plus atmospheric pressure on the water in the drain pan will cause the water to continue flowing,
EVEN AFTER THE PUMP HAS SWITCHED ITSELF OFF, until all the water in the system has evacuated itself.
IMPORTANT NOTES:
USING DISCHARGE HOSE OTHER THAN THE SIZE SPECIFIED (¼" ID) MAY RESULT IN REDUCED
PERFORMANCE.
CORRECT INSTALLATION OF SUPPLIED ANTI SIPHON DEVICE WILL ELIMINATE SIPHONING AND REPLACE AIR
BREAK AS SHOWN ON PAGE 5.
