INSTALLATION
Positioning & Mounting
The GME is designed to be installed : a. suspended horizontally beneath a level
or sloping ceiling, or
b. floor or wall mounted (i.e. vertically). Note: For an extra low profile the unit can be recessed into the ceiling (or wall).
Preparation
Prior to mounting the GME the mounting brackets must be detached from each end of the unit.
1. Open the end filter panel and locate the screw securing the unit endcaps (refer figure 2).
2. Remove the endcap securing screw and retain.
3. Remove the endcap by first sliding it forward approx. 20 mm, then pull outwards away from end of the unit.
4. Release each mounting bracket from behind the two bolts securing them to the unit.
5. Remove the floor mounting base from the back of the GME if when ceiling mounted it is required to fit flush to the wall.
Underceiling Mounting
Locate the GME near a wall to take full advantage of the long supply air throw and to hide the condensate drain pipe (and other connections) exiting at the rear of the unit.
Refrigeration and wiring connections are via the top or the rear access holes. A right­angled suction pipe extension is supplied to facilitate top exit.

Underceiling Installation
1. If an extra low profile installation is
preferred, first cut the required ceiling aperture.
2. Install four M8 threaded hanging rods (not supplied) to protrude no more than 30 mm below the level of the mounting bracket flange (refer figure 3).
3. Thread on and tighten the lower washer and locknut sets (not supplied) to secure the left and right mounting brackets. Note: Mounting bracket flanges face inwards.
4. Adjust distance between mounting brackets to match dimensions in figure 3.
5. Lift the unit to the mounting brackets locating the two protruding bolts, at each end of the unit, securely into the two slots provided in each mounting bracket, then tighten bolts to secure the GME unit.
6. Check that the secured GME is installed level to facilitate condensate drainage.
7. Complete all refrigeration piping connections (refer 'Indoor-Outdoor Unit Connections').
8. Fit the insulated condensate drain extension, orientated so that the drain vent tube is at the highest point in the condensate line.
9. After completing all piping connections replace the GME unit's left and right endcaps as follows: a. Place each endcap slightly forward of
the appropriate end of the unit,
b. Compress the endcap at its centre
and slide back hooking the endcaps hook under the 'U' shaped bracket on the unit and into position .
c. Secure each with the screws removed
earlier from behind the filter panels.
Wall / Floor Installation
Vertically mounted, the refrigeration and wiring connections can be made through the back or base of the unit.
1. Measure and cut wall recess, if required.
2. Secure the mounting brackets to the wall using fastenings suitable for the wall construction and weight of the GME unit. (Note: Mounting bracket flanges to face inwards.)
3. Refer to 'Underceiling Installation' instructions, steps 4 to 9 above, to complete vertically mounted installation.
INDOOR-OUTDOOR UNIT CONNECTIONS
Refer to the relevant OSA Outdoor Unit 'Installation & Maintenance' pamphlet for piping instructions. For wiring connections, refer to the Outdoor Unit wiring diagram in conjunction with the GME wiring diagram on this pamphlet.
REFRIGERATION PIPING
The GME Underceiling is shipped from the factory with a holding charge of dry nitrogen. Refer to the Outdoor Unit 'Installation & Maintenance' pamphlet for evacuation procedure.
GME 152 refrigerant line connections are: Liquid: 6 mm OD (1/4") flare nut Gas: 13 mm OD (1/2") flare nut
GME 222 refrigerant line connections are: Liquid: 10 mm OD (3/8") flare nut Gas: 16 mm OD (5/8") flare nut
GME 302 refrigerant line connections are: Liquid: 10 mm OD (3/8") flare nut Gas: 19 mm OD (3/4") sweat
GME 402 refrigerant line connections are: Liquid: 13 mm OD (1/2") flare nut Gas: 19 mm OD (3/4") sweat
GME 502, 702 refrig. line connections are: Liquid: 13 mm OD (1/2") flare nut Gas: 22 mm OD (7/8") sweat
Separation Limits
Maximum Pipe Length: Up to 30 m total * Indoor Unit above Outdoor Unit : 12 m * Outdoor Unit above Indoor Unit : 18 m *

*125 m total for GME 152 when
connected to OSA 45.
*210 m for GME 152 when
connected to OSA 45.
For line lengths in excess of the above, contact the manufacturer's nearest sales office for additional piping requirements.
CONDENSATE DRAIN
Connect a 19 mm ID drain pipe (not supplied) to the GME's drain connection. Maintain a downwards slope of at least 1 in 50 (20 mm/m) along the drain line. No ‘U’ trap is necessary.
Insulation of the GME 502 and 702 drain pipes is recommended especially in high humidity environments.
Note: The unit has a right angled drain tray to allow for wall or ceiling installation.
ELECTRICAL WIRING
The electrical supply required (via the Outdoor Unit) is specified on the Outdoor Unit's wiring diagram.
Electrical work must be carried out by a qualified electrician in accordance with local supply authority regulations and the wiring diagram.
Note: The TTS-11 Wall Thermostat automatically switches the indoor fan off during de-ice, therefore no additional wiring is required to achieve this result.
Note: The HAN-L6 Controller automatically switches the indoor fan off during de-ice, therefore no additional wiring is required to achieve this result.
COOLING OPERATION An Outdoor Unit fan speed controller is recommended where indoor cooling is required at ambient conditions below 20°C.
HAN-L6 CONTROLLER
The following components are supplied in a box beside the GME electrical box:
1. HAN-L6 Wall Control plaque, including wall mounting plate and screws.
2. 10 m interface lead (plaque-to-electrical box).
3.
User's Operating Instructions
booklet.
4. HAN-L6 Installation Instructions.
Optional
1. Remote return air temperature sensor on lead; 5 m or 10 m.
2. Remote wall mounted air temp. sensor on lead; 5 m or 10 m.
3. 20 m extended interface lead (plaque-to-electrical box).
4. GME electrical box–to–OSA outdoor unit interconnecting lead;
12.5 m or 25 m; 7 core.
5. Additional HAN-L6 Wall Control plaques (Note: maximium of 4 plaques in total).
Installation
The HAN-L6 Controller board is supplied pre-installed inside the GME unit's electrical box.
1
1. Isolate the GME unit from power supply, then remove electrical box cover.
2. Connect one end of the interconnecting cable (supplied separately) to the unit's terminals and the other end to your OSA outdoor unit as per wiring diagram, page 4.
4. Remove the Wall Control's interface lead from its box and connect one end of the interface lead to the colour coded terminal block on the HAN-L6 Controller board. Trace the remaining length of the lead to the wall plaque's intended location.
5. Ensure all interface and sensor wires are run separately and away from main power supply wires, including the interconnecting cable.
6. Replace the electrical box cover.
HAN-L6 Wall Control
Refer to the separate Installation Instructions supplied with the HAN-L6 Wall Control.
Remote Air Temperature Sensor/s (option)
The air temperature sensor is by default located in the Wall plaque. Optional remote air temperature sensors are available so that the measurement of the room temperature can be taken away from the wall plaque, eg. elsewhere in the room or in the return air duct.
If plugging the remote sensor into the Wall Control (TH1R) a jumper (JP1) must be repositioned to switch the active sensor to the remote location (refer separate HAN-L6 Installation Instructions).
Remote sensors can be plugged directly into the Controller board (PCB). This board accepts up to four sensors which are designated as 'zones' two to five. The first zone will always be the Wall Control itself. The Controller will always use the average of the zones selected. Refer to the separate installation instructions supplied with the PCB for further details.
