① Exhaust connection:

The exhaust hose can be installed either at the rear, left or right of the dryer.

② Power cord with plug

③ Control panel
④ Door
(5) Four height adjustable feet

Leveling the dryer

The dryer must be level to ensure safe and proper operation. Minor discrepancies do not have an adverse effect on operation.

The machine can be leveled by turning the legs clockwise or counterclockwise as necessary.

Determining the position of the exhaust connection

The exhaust connection can be left at the rear of the dryer (factory standard) or moved to the left or right side of the dryer.

Changing the position of the exhaust connection

• Remove the exhaust connection cover on the left or right side of the dryer.
• Do this by inserting a screwdriver into each raised flap and lifting upwards, as shown.

This cover is no longer needed.

Press the supplied cover firmly into the rear opening.
To remove the cap insert a screwdriver between the machine and the cap and lift upwards, the cap will then pop out of place.

Installation tips

An airflow gap of 3 / 8" (10 mm) must be provided between the machine and the floor. This airflow gap must not be blocked by a toekick or thick piled carpets.

Do not install the dryer next to a refrigerator. The warm air exhausting from the dryer can affect the thermostat of the refrigerator, causing it to run continuously.

Adapter

A ring adapter is supplied with the machine, and is compatible with all venting systems. The adapter helps prevent heat from escaping, and heats the air in the drum faster.

The adapter, 1, is inserted into the connector, 2.

Using the adapter with a maximum duct length of 33 ft (10 m) will result in shorter drying times and energy savings.

Exhaust connection with a flexible exhaust hose or rigid pipe

Using the connector supplied, an exhaust hose (4" [100 mm] diameter) can be installed.

Necessary materials:

• a wall or window duct
• an exhaust hose made of approved non-flammable material

If the duct length is more than 33 ft (10 m), remove the ring adapter, 1, from the connector, 2. If the duct length is less than 33 ft (10 m), leave the ring adapter in to improve time and energy efficiency.
Install the connector, 2, with the exhaust hose or pipe, 3, to the dryer.

How to calculate the effective duct length

The overall duct length will determine the duct diameter.

Measure the actual duct length needed to go from the dryer's exhaust connection to the vent outlet:

1. Establish the number of elbows or bends necessary, noting the type of bend, angle and radius involved (see Table).
2. Add the additional duct length (as derived by using the values specified in the table) and the actual duct length to get the effective length.

Note:

Maximum effective duct lengths:

4" (100 mm) diameter 66 ft (20 m)
5" (125 mm) diameter 132 ft (40 m)
6" (150 mm) diameter 328 ft (100 m)

Using the ring adapter up to an effective duct length of 33 ft (10 m) and a standard duct diameter of 4" (100 mm) will provide optimal drying times and energy consumption.

Do not use the ring adapter if the effective duct length is more than 33 ft (10 m).

Effective duct lengths over 66 ft (20 m) require a larger duct diameter.

Longer ducts may lead to slight decreases in dryer efficiency if the necessary duct diameter is not employed.

Tips about the ductwork

• Check with your local building code to determine the maximum allowable duct length.
• Use flexible metal pipe or rigid metal pipe for venting. Non-metallic flexible hose should not be used, it is a potential fire hazard.
• For best drying results avoid extra long ducting with too many bends, angles or tight corners.
• The shorter the exhaust ductwork, the more efficient the dryer will be. Expelled air is slowed down in the ducts due to friction against the inner walls. The shorter and smoother the inner walls are, the less friction will be created.
• An elbow or bend creates more friction than a straight duct. An additional duct length factor must be added for each elbow or bend (see Table). This factor expresses the resistance of the bend in terms of a straight length of duct. The additional length factor is then added to the existing duct to give the effective length.

A larger duct diameter helps reduce friction. Therefore the duct diameter and length should be increased simultaneously.

Additional duct lengths (4" rigid pipe only)
Type of bend	Radius		Additional duct length
	ft	cm	ft	cm
Flexible metal duct
- 3' 3" (1 m) straight			5' 11"	180
- 45° angle	10"	25	4' 11"	150
- 90° angle	10"	25	8' 2"	250
Smooth metal duct
- 3' 3" (1 m) straight			3' 3"	100
- 45° angle	10"	25	1' 11"	60
- 90° angle	10"	25	2' 7"	80
Elbow 90° sharp			7' 6"	230
Concertina bend
- 90° angle	8"	20	2' 4"	70
Wall vent or window vent
- with louvers			12' 5"	380
- with flap			4' 11"	150
Exhaust connection
- left or right side			3' 3"	100

Example: Calculating the effective duct length and required internal duct diameter

Rigid pipe		Duct length ft	Duct length m
A	Wall duct with louvered wall vent	12' 5"	3.8 m
B	90° bend	2' 7"	0.8 m
C	20" (0.5 m) rigid pipe	1' 7"	0.5 m
D	90° bend	2' 7"	0.8 m
E	left vent opening	3' 3"	1.0 m
Total duct length		22' 5"	6.9 m

The total duct length is less than 33 feet (10 m), so a duct diameter of 4'' (100 mm) with adapter is sufficient.
