DH150/300/600 OWNER INSTALLATION MANUAL

Models DH150, DH300 & DH600 are designed to remove moisture from e
air and reject e latent heat of e dehumidification process back into e air.
Warm, humid air is drawn in rough e evaporator which extracts e latent
heat and at e same time dehumidifies e air by cooling it below its dew
point temperature. The condensed moisture forms on e evaporator coil and is
en drained to waste. The extracted heat is en upgraded to a much higher
temperature by e compressor and passes into e condenser coil. The cool,
drier air en passes over e condenser, collects e heat and passes back into
e room as warm, dry air.

SD208050 ISSUE 44

Great care should be exercised in following e installation procedure to ensure
at your Calorex dehumidifier performs as it was designed.
3.1 SITING
a. Ensure dehumidifier on site is as ordered, i.e. model, electrical supply and
factory fitted options.
b. Inspect unit for damage, in particular inspect e evaporator (finned side)
to ensure at it is undamaged. (Minor indentations in e fins do not affect
performance). If severely damaged, endorse delivery note in presence of e
driver and send a recorded delivery letter to transport company giving details.
c. Protect unit if installation is delayed.
d. Provide a firm level base capable of supporting operational weight of unit;
spread load if on timber floor.
e. Ensure water cannot collect under unit, recommend units are installed on
plins 100mm above finished floor level and to also aid condensate drainage.
f. Allow adequate clearance to service panels on unit; recommend 500mm
minimum (see installation drawings).
g. All Calorex dehumidifiers are by design as quiet as is practicable, however,
due consideration should be given to siting in order to fully exploit is feature,
i.e. orientate inlet/outlet parallel to occupied premises.
h. Ensure loose debris will not block air inlet filters or grilles.

DH150/300/600 OWNER INSTALLATION MANUAL

IMPORTANT:
As dehumidifier units are handling air at dehumidified space
temperatures, ey must be sited in a similar environment, or insulated
plenum. They must not be sited in colder areas, i.e. subject to ambient
air.
3.2 DUCTING
(SEE FIGS 3, 4, 5 AND 6)
In order at moisture can be removed and humidity control can be effected
wiin e required area, it is essential at correct air movement and
distribution is achieved. The Calorex unit must extract e humid air generated
and discharge e drier air to areas which are subject to condensation problems
(windows, etc.) and or comfort zones, etc.
This can oen be achieved by use of ducting and correct application of grilles/
louvres to effect air distribution and movement to ese areas.
NOTE:- dehumidifier unit and ducting will be at higher temperature and will
require insulation if exposed to lower air temperatures, for instance, if e
ducting were to pass rough an un-heated lo space.

Exhaust from Wet Area - Humid Air - Should be taken from as low as
practicable to inlet of dehumidifier unit. In many instances siting of dehumidifier
unit in hall or in adjacent rooms can eliminate use of ductwork to inlet.
Inlet/Return - Dry Air - Frequently requires overhead ducting wi suitable
grilles to give balance and direction of air flow.
The quantity of air flow handled by each dehumidifier unit is given on e data
sheet togeer wi e maximum pressure available from e fan to overcome
total ducting resistance to air flow, i.e. inlet, discharge ducting, grilles, filters and
where, installed air heater batteries.
Note:-
a. The humidity sensing tube situated by e air inlet is to be encompassed by
or extended to any inlet air ducting.
Refer to installation drawings.
b. All units have discharge ducting spigots as standard.
c. Inlet ducting spigots and or inlet air filters are available from stockists. Do not
drill into unit to fit spigots or filters.
d. Final connections to dehumidifier spigots must be made wi flexible ducting
(rubber or canvas) to eliminate transmission of vibration down any ducting
fitted.
e. Before any discharge ducting is attached remove e damper plate (if fitted)
from dehumidifier outlet or fan grille.
f. Aer completion of installation including all grilles, ductwork, etc., ensure at
e air flow rough e dehumidifier is as specified in e data sheet ± 10%.
If airflow is high, adjust e main system damper to obtain correct airflow. If
airflow is low or high, unit will not function correctly.
g. TABLE 1. Required Free Areas to provide air flow to and from dehumidifiers
when installed in an enclosed area or where required to pass air rough a wall,
etc.
Free area is e available area rough which air can pass, rough a
grille or louvres.
Model DH150 - minimum free area air inlet = 0·35 m².
Model DH300 - minimum free area air inlet = 0·57 m².
Model DH600 - minimum free area air inlet = 1·1 m².
Note: If multiple units are installed in an enclosed area en e inlet free areas
required for each unit can be added togeer to form one inlet aperture. BUT
discharge from each unit must be kept separate and must not be incorporated
into one common duct system, unless back dra flaps are installed in outlet
duct of each dehumidifier.

problem, or if e external interlock facility is open circuit.
c. DEFROST - WHITE - Illuminates whenever e dehumidifier is in defrost
mode, is will happen at lower air temperatures and is not a fault condition,
e dehumidifier will revert to normal run automatically when e defrost cycle
is complete.
d. ON/OFF SWITCH - This will only be found on DH150 models and should
always be used if for some reason e dehumidifier is not required to be
running or prior to isolating e dehumidifier from e mains electrical supply.
e. STANDBY SWITCH - This will only be found on DH300/600 models and
must always be used if for some reason e dehumidifier is not required to be
running or prior to isolating e dehumidifier from e mains electrical supply.
IMPORTANT - On initial start up or if e mains electrical supply has been
interrupted for any leng of time (greater an 1 hour), en e standby
switch must be set to “standby” before e mains electrical supply is
reinstated, e dehumidifier must be le in is condition for 12 hours before
normal run is selected on e standby switch.
Internal Controls.
f. An adjustable internal humidistat effects control of humidity. Range 20/80%.
A normal setting is 60% for achieving comfortable conditions and minimising
condensation. (20% setting will remove more moisture from e dehumidified
space an a 80% setting).
g. An adjustable ermostat effects control of e air temperature and should be
set to e maximum desired air temperature for e dehumidified space.
h. Fan mode switch. This gives e user e option of having e fan cycle
under control of e humidistat (wi e compressor), or e fan can run
continuously which will promote better air circulation which again helps to
reduce condensation by preventing stagnant air pockets.
i. If e Turning Hood Top Box Heater assembly option is fitted, en e
adjustable air temperature ermostat control, located on e side of e Top
Box Heater assembly should be set to e desired minimum air temperature
