Electromagnetic Compatibility and Low
Voltage), as required throughout the
European Community, to guarantee
correct standards of safety.
In order to guarantee the very highest standards and
performance, we manage every stage in the
manufacturing of our products. Throughout the
production process we maintain strict control,
starting with our extensive resources in research
and development through to the design and
manufacture of almost every individual component,
from molded plastics to the assembly of units and
controllers.

SK2020 GLOBAL PDWA-V/P-AC-001
General Description
The Duct Fan Coil is designed to meet and exceed the demanding requirements for efficiency and quiet operation.
Structure
The structure is made from heavy gauge galvanized steel panels with couplings for the connection of ducting and a gravity
drain pan with insulation for condensation. Fire resistant insulation is optional for internal case to provide both thermal and
acoustic insulation. Insulation is also fitted on the top of coil.
Condensate Pans
Positive sloped drain pans are steel and powder coated with self-extinguishing closed cell expanded polyethylene with
thermal properties. The drain pan outlet is 3/4” (standard on the same side of coil connections).
Coils
Constructed with seamless copper tubes and headers. The tubes are mechanically expanded into corrugated aluminum fin
material for a permanent primary to secondary surface bond. Coils are tested at 35 bar and recommended for maximum
operation at 20 bar. Coils include manual air vent and water purge valve.
Fan Wheels
They are double inlet forward curved centrifugal type. Wheels are statically and dynamically balanced for smooth, quite
operation. The housing is constructed from heavy gauge galvanized steel with die-formed inlet cones.
AC Motor
Standard motors are PSC, permanently lubricated type with internal thermal overload protection. The unit is using 3-speed
AC motor.
Air filter
It is easily removable and washable and is made from self-extinguishing acrylic with an efficiency of class EU2 (G2)
(Merv 2-4). G4 (Merv 8) efficiency is as optional.
Complete Function Control (AC-S1 type)
The PCB (printed circuit board) Modbus microprocessor controls functionality of the indoor fan motor, water valves (ON/OFF)
and electric heater (optional), to maintain room conditions at a user-defined set point. Temperature settings, fan speeds and
other control functions can be changed by either infrared handset or wired wall pad controller.
Terminal Strip (T1 type)
Terminal block is preinstalled and connected to AC motor. The motor can be controlled by external thermostat. 40VA (24VAC)
transformer is optional which supplies power to thermostat and modulating valve.
Terminal Strip (T2 type)
A 24VAC relays board is used to drive 3-speed AC motor. 40VA (24VAC) transformer is optional and supplies power to
thermostat and modulating valve.
Casing with insulation (Optional)
Coil with insulation on top
Sides with insulation
Fan Deck

Location
Confirm there is enough space for unit installation and maintenance. Please refer to below figure for the unit's outlines
and dimensions and for the minimum distance between the unit and the obstacle/ any obstructions/ its surroundings.
Ensure there is enough space for piping connections and electrical wiring.
Check whether the hanging rods can support the weight of the unit (see specification table for weight of the unit).
Confirm the unit is installed horizontally to ensure proper operation and condensate draining.

Insulation
Confirm the Chilled water pipes and all parts on the pipes are insulated.
Confirm insulation is installed on the supply air duct.
Service Connection
Confirm duct connections are sealed.
Confirm water piping INLET is at the BOTTOM, water OUTLET is at the TOP.
Confirm no water leakage is observed at the piping and condensate drain connections.
Confirm drain pipe slope is minimum 1:50.
Unit Operation
Confirm air has been properly bled from and there is waterflow through the coil.
Confirm fan wheel is rotating and air is discharged at unit supply opening
Confirm power voltage between Terminals L1 and N.
Confirm thermostat voltage (if equipped).
Verify desired fan speed is receiving power from the thermostat.
Check functionality of motor with a call for heating or cooling.
Confirm system ESP is per schedule.
Confirm control valve(s) functionality.
CAUTIONS
Dimension M and N are determined by air duct design.
Air duct should be fire-proof. Please refer to concerned country national and local regulation.
Circulatory air pressure drop should be approximately equal to the External Static Pressure.
Caution
When connecting pipe to fan coil unit, do not bend or reposition the coil header for alignment purposes. This
could cause a tubing fracture resulting in a water leak when water pressure is applied to the system.

General Maintenance
1. Installation and maintenance should be performed by qualified personnel who are familiar with local codes and
regulations, and are also experienced with this type of appliance.
2. Confirm that the unit has been switched OFF before installing or servicing the unit.
3. A good general maintenance plan will prevent damage to and unexpected shutting down of the equipment.
4. Dirty filters reduce air flow as well as unit performance. Therefore, changing or cleaning the filters is very important. Check
the cleanliness of the filter and replace or clean as required monthly.
5. Coils should be cleaned with compressed air or water to remove dust, dirt or lint. They can be brushed with a soft brush
or vacuumed with a vacuum cleaner.
6. If the water coil is not being used during the winter season it should be drained, or an anti-freezing solution should be
added to the water circuit to avoid freezing.
Regular Maintenance
1. Inspect and clean the condensate drain pan to avoid any clogging of the drain by dirt, dust, etc. Inspect drainage piping to
ensure the proper condensate flow.
2. Check and clean the coil. Clean the coils with low-pressure water jets or low-pressure air.
3. Clean and tighten all the wiring connections.
4. Drain out the water system and check for buildup of mineral deposits.
Filter Cleaning
1. Remove the filter from bottom or side.
2. Clean the filter with a brush, or with water.
3. Replace the filter by sliding it back into the flame.
Fan Motor Assembly Maintenance
1. Remove the screws from the bottom panel.
2. Remove 4 screws from the both sides of the unit.

water outlet need to be exchanged. After interchanged, the
upper is water inlet and the bottom is water outlet.
Electric Heater Replacement

new PDWA-EH module.
2. Remove PDWA discharge flange and install it on the EH
module. (Skip this step if no removable flange.)
3. Screw PDWA discharge flange onto EH module and then
install the EH module to the unit.
4. Connect “L”& “N”ports to PDWA terminal “L”& “N”
connected to 230V/1Ph power supply. Connect “EH” port
to related terminal on PDWA which is control signal from
thermostat or S-type control board.
