Heat Exchanger Module Installation

- Select and mark the position for fixing bolts.
- Drill the hole for set anchor on the face of ceiling.
!
CAUTION
• Tighten the nut and bolt to prevent unit falling
- Insert the set anchor and washer onto the suspension bolts for
locking the suspension bolts on the ceiling.
- Mount the suspension bolts to the set anchor firmly.
- Secure the installation plates onto the suspension bolts (adjust level
roughly) using nuts, washers and spring washers.

Method when insatalling the ducting

- Ducting is to be field supplied
- For prevent water from flowing into the Heat exchanger module,
Make sure the ductiong has slopes down
- You Protect the ducting against reverse airflow from wind.
- If the suction ducting or discharge ducting is connected with the
inside air, it might be impossible to reach the desired room
temperature.
- Connect suction ducting and discharge ducting with the outside air.
Method connect the refrigerant piping to the
Heat Exchanger Module.
1. Cut the liquid pipe and gas pipe.
2. Burrs removal
- Completely remove all burrs from the cut cross section of
pipe/tube.
- Put the end of the copper tube/pipe to downward direction as you
remove burrs in order to avoid to let burrs drop in the tubing.

3. Wrap the pipe with a wet cloth.
4. Braze the liquid pipe and gas pipe.
5. Remove the wet cloth.
Insulation, others : Insulate the joint and tubes
completely.
