INSTALLATION
INITIAL CHECK
- To avoid damage, the unit should not be removed from its carton until the final location is reached.
- Inspect the unit for shipping damage and file a claim with the transport agency if necessary.
- Check the following fields of electrical work:
- a. Proper size of fuses and wire.
- b. Correct wiring connections and grounding as specified by local electrical codes.
- c. Check supply voltage, which must be within the limits shown on the nameplate.
- Check for proper condensate flow.
- Be sure piping insulation is adequate.
- Confirm there is no obstruction to the airflow for indoor and outdoor units.
- Check for sufficient clearances for servicing of the units.
LOCATION & MOUNTING
- The units should be installed horizontally.
- Prepare the unit mounting such that the unit is sufficiently supported.
- When mounting the indoor unit on the ceiling, select a location that allows the air current to circulate evenly throughout the room.
REFRIGERANT PIPING
- Connections to the indoor unit are flared.
- Make flare joints for both suction and liquid lines.
- To provide concentric seating of tube on fitting, as well as prevent leakage, ensure tube and fittings are aligned with one another before tightening nut.
- The liquid line and suction line should run according to the piping design shown in Fig. 4.
- Brazing should be performed with a constant purge of nitrogen through the piping. This is to keep the inner tube clean.
- Insulate suction and liquid lines separately to prevent sweating.
- Use two spanners to make the flare nut connection to the indoor unit.
