rated flow titanium heat exchanger
requires no
special
plumbing
arrangementsexcept
bypass(please setthe
flow rateaccording to the
nameplate). The water
pressure
drop
is less than 10kPa at max.
Flow rate. Sincethere is
no
residual heat orflame Temperatures,
The unit does notneed copper
heatsink
piping.
PVC

CONDENSATION
DRAIN
BARB FTG
Condensation: Since theHeat
pump
coolsdown the airabout
4
-5C,
water maycondense on
the
fins
ofthe horseshoe shapedevaporator.
lf the relative humidityis very high,this could
be as muchas several litresan hour.The
waterwill run downthe fins inioihe basepan and
drain out throughthe barbed
plasticcondensation
drain fittingon the sideof the basepan.
This fitting ls designed to accept
20mm
clear
vinyltubing which can be
pushed
on by hand
and run toa suitable drain.lt is easyto
mistake
thecondensation
for awater leak insidethe
unit.
NB: Aquick way toverify that thewater is condensation
is to shutoff the unit and keepthe
pool pump
running.lf the waterstops
running outof the basepan, it is condensation.AN
EVEN
QUICKER
WAYIS toTEST THEDRAIN WATER FOR CHLORINE. if theis no chlorine
present,
then it's condensation.
