3 Preparation

3.1 Preparing installation site

3.1.1 Installation site requirements of the outdoor unit

Mind the spacing guidelines. See the "Technical data" chapter, and
the figures on the inside of the front cover.

INFORMATION

The sound pressure level is less than 70dBA.

The outdoor unit is designed for outdoor installation only, and for
ambient temperatures ranging:

Model Cooling Heating

RZQG –15~50°C –20~15.5°C

4 Installation

4.1 Mounting the outdoor unit

4.1.1 To provide the installation structure

Prepare 4 sets of anchor bolts, nuts and washers (field supply) as
follows:

4.1.2 To install the outdoor unit

4.1.3 To provide drainage

Make sure that condensation water can be evacuated properly.

INFORMATION

If necessary, you can use a drain plug kit (field supply) to
prevent drain water from dripping.

NOTICE

If drain holes of the outdoor unit are covered by a mounting
base or by floor surface, raise the unit to provide a free
space of more than 150mm under the outdoor unit.

Installation manual

4

a Make sure not to cover the drain holes.

INFORMATION

The recommended height of the upper protruding part of
the bolts is 20mm.

NOTICE

Fix the outdoor unit to the foundation bolts using nuts with
resin washers (a). If the coating on the fastening area is
stripped off, the nuts rust easily.

Snow

In regions with snowfall, snow might build up and freeze between the
heat exchanger and the external plate. This might decrease the
operating efficiency. To prevent this:

1 Drill (a, 4×) and remove the knockout hole (b).



2 Remove the burrs, and paint the edges and areas around the

edges using repair paint to prevent rusting.

4.1.4 To prevent the outdoor unit from falling over

1 Prepare 2 cables as indicated in the following illustration (field

supply).

2 Place the 2 cables over the outdoor unit.

3 Insert a rubber sheet between the cables and the outdoor unit

to prevent the cable from scratching the paint (field supply).

4 Attach the cable’s ends. Tighten those ends.

3 If you have chosen the downwards piping route:

▪ Drill (a, 4×) and remove the knockout hole (b).
▪ Cut out the slits (c) with a metal saw.

4 Do the following:

▪ Connect the liquid pipe (a) to the liquid stop valve.
▪ Connect the gas pipe (b) to the gas stop valve.

5 Do the following:

▪ Insulate the liquid piping (a) and the gas piping (b).
▪ Wind heat insulation around the curves, and then cover it

with vinyl tape (c).

▪ Make sure the field piping does not touch any compressor

components (d).

▪ Seal the insulation ends (sealant etc.) (e).

4.2 Connecting the refrigerant piping

DANGER: RISK OF BURNING

4.2.1 To connect the refrigerant piping to the outdoor unit

1 Do the following:

▪ Remove the service cover (a) with screw (b).
▪ Remove the piping intake plate (c) with screw (d).

2 Choose a piping route (a, b, c or d).

6 If the outdoor unit is installed above the indoor unit, cover the

stop valves (f, see above) with sealing material to prevent
condensed water on the stop valves from moving to the indoor
unit.

NOTICE

Any exposed piping might cause condensation.

7 Reattach the service cover and the piping intake plate.

8 Seal all gaps (example: a) to prevent snow and small animals

from entering the system.
