This product needs to be installed properly in order to ensure maximum functionality as well as safety.

Please make sure to read this installation manual before starting the installation.

l Installation must be performed by a dealer or installation contractor. Please note that improper installation may cause malfunction or accident.

“Operating Instructions” and this manual must be handed over to the customer after completing the installation.

1. Safety precautions

The following signs indicate that death or serious injury may be caused by failure to heed the precautions described below.

WARNING

Do not modify or disassemble.

(It could cause re, electric shock or injury.)

Do not

disassemble

Prohibition of use in

bath or shower room

Connect the

grounding wire.

The instructions

given must be

followed.

The instructions

given must be

followed.

The Lossnay unit and remote controller should not be

installed where it is highly humid, like a bathroom, or

other wet place.

(It could cause electric shock or power leakage.)

Connect the product properly to ground.

(Malfunctioning or power leaks can cause electrical shock.)

Wiring work must be performed by qualied

professionals, and be implemented safely and securely

in accordance with the engineering standards and the

extension wiring rules for electrical equipment.

(Poor connection or improper wiring work could cause

electric shock or re.)

Install a power supply isolator at the power supply

side as per local electrical regulations. All supply

circuits must be disconnected before obtaining

access to the terminal devices. Use the specied

cable size and connect the cables securely to prevent

disconnection when they are pulled.

(If there is a defect in the connection, there is a possibility

of re.)

Select an adequate place for the opening to introduce

outdoor air, where it will not intake the exhaust fumes

like combustion gas, or others, and there is no risk of

blockage.

(Shortage of fresh air could put the room in a state of

oxygen deciency.)

A duct made of steel must be installed with care not

to be connected electrically with metal, wire, stainless

steel plate, or others.

(It could cause re when power leakage occurs.)

Not suitable for use with solid-state speed controls.

Use the specied power supply and voltage.

(Use of incorrect power supply or voltage could cause re

or electric shock.)

Select a place with su󰀩cient strength and install the

main unit securely.

(It could cause injury if it falls.)

7. Trial operation After the system has been installed and before the ceiling panel is installed, make sure that wires are properly connected, then test the system’s operation, referring to the operation manual for the remote controller. 1. Trial operation using the remote controller (PZ-62DR-E) Follow the procedure shown in the operation manual for the remote controller the functions below. (1) Start operation (2) Fan speed selection (3) Ventilation mode selection (4) Stop operation 2.
PAGE 30
7. Trial operation (continued) 4. If trouble occurs during trial operation Symptom Lossnay does not operate even when the operation switch of the remote controller (PZ-62DR-E) is pressed. Remedy • Check the power supply. (The specified power supply is single-phase 208-230 V 60 Hz) • Check for a short circuit or disconnection in the transmission cable. (Check that the voltage between terminals in the transmission cables is 10 to 13 VDC for the PZ-62DR-E.
