Installation Method
1. Model Installation
■
You are required to prepare the ceiling suspension bolts, nuts and washers.
■
Install the unit firmly and horizontally enough to support its weight. (Fig. 1)
■
If you do not fit it firmly, it is not only dangerous but also easily vibrated. If it is
not fitted horizontally, the damper unit becomes defective in operation.
Caution
• When you are required to be cautious on prevention of vibration, we
recommend you to use the anti-vibration ceiling suspension fixtures.
• Never fail to make an inspection opening with
450 mm or more at the place
shown on the paragraph of "Cautions For Operation", so that you can inspect
filters, Heat Exchange Elements, power source and motors.
2. Cautions on Installing The Unit Body Upside
Down
■
Re-fit the ceiling suspension fixture in an opposite side. (If they are left as it is, the foolproof function of ceiling suspension bolts do
not work and will cause the danger of dropping of the unit.)
■
Printed indication is in a reversed position.
In particular, be careful of the arrow mark [
] showing the direction of inserting a Heat Exchange Element.
Electric Works
Have a specialized working contractor perform wiring in accordance with the laws and regulations of the country concerned.
■
Connect the broken lines in the wiring diagram.
■
We recommend that you use a switch having more than 3 mm distance to break contact and more than 15A rated current.
