2.1 PLUMBING
CONDENSATE DRAIN
The condensate driptray in the ‘AA300/AA500’ unit collects the water
removed by the dehumidification process.
It is therefore necessary to ensure that the’AA300/AA500’ unit is placed on a
level plinth so that the condensate can run away and not overflow the edges of
the driptray inside the machine.
The ‘AA300VHF’ has a 3/4” BSPM threaded condensate drain connection.
The drain pipe should run away with adequate fall to waste ie 1/2” per foot
minimum and must incorporate a ‘U’ trap & tun dish.
BOILER PLUMBING
The boiler connections on the machine are 3/4”BSPM. for connecting the boiler
water flow and return.
Suitable breakable couplings, isolation, and drain down valves should be
installed in the boiler water flow and return pipes local to the ‘AA300/AA500’
unit.
Refer to the boiler manufacturers instructions before designing the pipework
system.
POOL WATER CONNECTIONS
The pool water connections in the machine are 1” BSPM uPVC.
Suitable breakable couplings, isolation, and drain down valves should be
installed in the pool water flow and return pipes local to the ‘AA300/AA500’
unit.
IMPORTANT GENERAL CONDITIONS
1) Do not route water pipes across service access panels or air inlet/outlets.
2) The water circuits to and from the ‘AA300/AA500’ unit should be capable
of maintaining the specified water flow limits required by the machine. See Data
sheet section 4.0.
3) All pipework must be adequately supported with allowance for expansion
and contraction especially with regard to the plastic pipework.
4) It is recommended that when installing water systems the last connections
to be made should be adjacent to the ‘AA300/AA500’ unit to avoid undue
stresses on the unit connections.
