Whe you eed some optio al devices such as a hu-
midifier, electric heater, etc., be sure to use the products
which are recomme ded by us. These devices should
be attached by a professio al i staller.
Applicatio to i ferior e viro me t such as a e gi-
eeri g shop, could cause equipme t malfu ctio a d

Period of warm-up
With the heat pump type warmi g, the mecha ism of heat pump that co ce trate heat of outdoor
air with the help of refrigera t to warm the i door space, is utilized.
Whe a room is warmed with a heat pump type air co ditio er, frost accumulates o the heat ex-
cha ger of outdoor u it alo g with the drop of i door temperature. Si ce the accumulated frost re-
duces the effect of warmi g, it is ecessery to automatically switch the operatio to the defrosti g
mode. Duri g the defrosti g operatio , heati g operatio is i terrupted.
Warmi g capacity of heat pump type air co ditio er decreases alo g with the
drop of outdoor temperature.
Whe the warmi g capacity is ot sufficie t, it is recomme ded to use a other
heati g impleme t.
Si ce the heat pump type air co ditio er employs a method to circulate warm
wi ds to warm the e tire space of a room, it takes time before the room tem-
perature rises.
It is recomme dable to start the operatio a little earlier i a very cold mor i g.

8. The attentive matters in installation of air suction and discharging duct
Recomme d to use a ti-frost a d sou d-absorbi g
duct. (locally bought)
The duct i stallatio work should be fi ished
before the fitme t of ceili g.
The duct must be heat i sulated.
The specific air-dischargi g outlet should be i stalled at
the place where the airflow ca be reaso ably distributed.
The surface should leave a checki g meatus for checki g
a d mai te a ce.
9. The examples of improper installation
Do ot use air i duct a d take the ceili g i er side i stead. The result is because of the irregular
outer air mass, stro g wi d a d su shi e, the humidity is i creased.
There may be water drop o the outside of duct. For ceme t a d other ew co structio s, eve if
ot taki g ceili g i er side as duct, the humidity will also be so high. At this time, use glass fiber
to perform heat preservatio to the whole. (use iro et to bi d the glass fiber)
Affected by the capacity of air dischargi g fa , the stro g wi d i the outer duct a d wi d directio ,
whe u it air se di g volume exceeds the limit, the discharged water of heat excha ger will overflow,
leadi g to water leakage.

10. The operation method of fan controller
Through the fa co troller switch i the electric box, the air volume of this u it ca be co ti uously
adjusted.
It is u ecessary to adjust air volume through the duct side wi d level (u it outside static adjustme t).
The air volume set should be i the operatio air volume ra ge.
Figure I shows the positio of fa co troller i the electric box a d operatio method.
After fi ishi g the electric work, perform test ru . Accordi g to the mai poi ts i Figure II maki g the
chose switch No. accorda t. A d co firm if it reaches the eeded air volume.
Note:
1) Whe operati g the fa co troller, it is possible to touch the electric chargi g part, so do cut off the
power supply.
2) Do ot set the dial at the positio less tha 1.
3) The figure circled i Figure 2 i dicate the capacity umber of fa co troller( for AD482AHEAA).
The o -listed capacity umber may exceed the permitted operatio capacity ra ge, so it is impossible to
operate.
4) Whe deliveri g from factory, the capacity umber of fa co troller is set at No.5.
