Maintenance
Preparation
Prior to mounting the GMW 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 3).
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.
Mounting
Locate the GMW 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.
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 2).
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 4.
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 GMW unit.
6. Check that the secured GMW is installed
level to facilitate condensate drainage.
7. Complete all water piping connections.
8. If the unit is to be used for cooling, 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 GMW 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.
