CONDENSATE DRAIN DHPU(L)
The DHPU(L) coil will act as an evaporator during the
heating cycle and create water.
A condensate drain
must be fitted.
Remove the plate from the valve end mounting foot
and fit a 22mm ID hose to the copper stub.
Route the hose through one of the knockouts.
A 5m head condensate pump kit (54300452) is
available for applications where gravity drain is not
possible.
Each unit is supplied with air inlet and discharge spigots.(see page 2 for sizes)
These may be used for connecting installers ducting or used with the optional duct, plenum and grille kits
(refer to kit instructions for installation)
NOTE:
It is essential that ducting is adequately insulated to prevent sweating. An insulation thickness of at
least 45mm is recommended.

To maximise performance, pipe runs should be kept as short as possible. However, individual pipe runs
to a maximum of 80m (50m on sizes 15 & 20) including 20m lift are permissible, provided good
refrigeration practice is followed.
Performance rating is based on 7.5m pipe runs. Correctly sized pipes for each installation and fitting the
correct expansion orifice will result in no significant loss of capacity on extended pipe runs.
a
Pipe sizes are based on:-
Minimum of 3.8 m/s (750 fpm) suction gas velocity for horizontal or downflow.
Minimum of 7.6 m/s (1500 fpm) suction gas velocity for upflow.
Maximum of 15.2 m/s (3000 fpm) suction gas.
b
Where vertical risers exceed 5m, oil traps must be formed in the pipe. This will help ensure that
oil returns to the compressor. Typically fit an oil trap every 3m with a trap at the bottom of the
riser.
