Rinnai RPC26MCWF Portable Room Air Conditioner

Introduction

This portable air conditioner can alter the room temperature and humidity. It has multiple functions of cooling, dehumidifying (drying), and fan ventilation, and can be moved from room to room and transported from building to building easily.

The air conditioner can maintain set room indoor air temperatures between 16°C and 32°C. The set room temperature is displayed on the remote control and in the control panel on the unit. This does not mean that the air conditioner will necessarily reduce the actual room temperature to the set room temperature.

• Do not place the air conditioner or plastic window slider in direct sunlight. Close all curtains in the room being cooled.
• For maximum cooling (COOLING MODE), set the temperature at 18°C and the fan at HIGH. After approximately 3 minutes, the compressor will turn on and cooled air will come out of the front air outlet. Warm air will also come out of the rear outlet and into the exhaust hose.
• In COOLING MODE, the air conditioner will not cool unless the set temperature is below the existing room temperature.
• In COOLING MODE, once the existing room temperature reaches the set temperature, the fan continues operating and the compressor switches on and off to maintain the set temperature within the room.
• For maximum cooling output, keep the exhaust hose as short and as straight as possible. Minimize bends, which can reduce the maximum cooling capacity of the air conditioner. Elevate the air conditioner if necessary.
• Make sure the air intake and outlet grills are unobstructed.
• Clean the filters at least once every two weeks.

Installation

Location

This portable air conditioner must be installed on a flat and dry surface. A minimum clearance of 500mm from walls or other appliances is required, along with easy access to a power point (GPO). The air outlets and the ducting system must not be obstructed.

The appliance is fitted with a 1.7m flexible cord (220-240V 50Hz 10A). The maximum duct extension is 1.8m in total. Consider both factors when determining the location.

Duct Assembly

1. Place the Duct to Unit Adaptor (17) over the Exhaust Outlet (5), pushing it downwards to engage the Exhaust Outlet tabs.
2. Screw one end of the Exhaust Duct (16) into the Duct to Unit Adaptor (17).
3. Attach the Window Exhaust Duct Adaptor (15) to the other end of the Exhaust Duct (16).

Exhaust Ducting Options

Two ducting options are available: Window installation or an optional Semi-permanent wall installation.

DO NOT overextend the exhaust duct. Overextension can lead to kinking, causing air flow restrictions and reducing efficiency. Keep the exhaust duct as short and straight as possible.

Window Installations

The window kit fits most standard vertical and horizontal windows. Some window types may require minor modifications.

Minimum and maximum horizontal/vertical window opening dimensions:

A - Minimum = 675mm, A - Maximum = 1250mm.

1. Once a suitable window is chosen, fit the Adjustable Slider Kit (14) into the window area and secure its length using the supplied slide lock nut and bolt.
2. Connect the Window Exhaust Duct Adaptor (15) to the Adjustable Slider Kit (14).

It is recommended to place foam draft sealing strip along the edges of the kit or window opening to form a seal.

Semi-Permanent Wall Installation

For situations where a window opening is not accessible, a Wall Exhaust Adaptor and Wall Exhaust Terminal are required (not supplied, order separately). Installation of the wall flange should be completed by an authorised person and comply with all municipal building codes and OH&S guidelines.

Condensate Drainage

Condensate produced by this appliance is not potable; dispose of via a waste outlet or allow to evaporate.

Internal Condensate Tank

The appliance has an inbuilt condensate tank. If all drain outlets (7, 8, and 12) are plugged, the tank may reach capacity. If this occurs, the appliance will stop operation, displaying a "P1" code. To resume operation, the condensate tank must be drained:

1. Place a shallow tray (at least 1 litre volume) under the Drain Tray Outlet (12).
2. Remove the plug from Drain Tray Outlet (12), drain the condensate, and replace the plug. The appliance can then resume operation.

Fixed Condensate Drainage Hose

As an alternative to the internal tank, a condensate drain hose (18) can be fitted.

• Option 1 (External Drain Tray): With drain outlets (8) and (12) plugged, fit the condensate drain hose (18) to drain outlet (7) and drain condensate into a drain tray.
• Option 2 (Waste Outlet): With drain outlets (7) and (8) plugged, fit the condensate drain hose (18) to drain outlet (12) and drain condensate into a drain tray or waste outlet.

The point to which condensate is drained MUST be lower than the drainage outlet point. Ensure the tray capacity is greater than the condensate produced.
