Precautions

Flush Mounting

1. To mount the adapter to the panel cutout, first deform the adapter

by pushing it on the two opposing corners (as indicated by arrows
A. Then push part B into t he cutout (i.e., toward the back of the
panel).

2. After the adapter is mounted, inser t the H2F as shown in the fig­ure below. Secure the H2F b y tightening the two mounting screws
(M3 x 16) included as accessories.

3. If the lead wires have been connected to the H2F from the front of
the panel before the H2F is mounted in the panel, engage the
H2F to part A of the adapter and push it in the direction of B. Then
tighten the two screws as described in 2.

Time Setting

To set the time, turn the center knob clockwise to the correct time.
Turning it counterclockwise or turning it with your fingers hooked on
the setting bracket may cause a malfunction.

With 24-hour models, set the hour to the arrow on the upper left cor­ner of the front panel and the minute to the arrow on the center knob.

With 1-week models, set the day of the week to the arrow on the
upper left corner of the front panel and the hour to the arrow on the
center knob.

6 24-hour/Weekly Time Switch H2F

Use the gold setting tabs to set the ON time and the silver ones to set
the OFF time. Position the thick leg of the tab toward the outside of
the dial and insert the tab securely into the groove on the dial.

Three pairs of setting tabs are attached.
Store the spare tabs in the compartment at the lower right corner of
the front panel.

Manual Switch

H2F-@M Series (Quartz Motor Models)

SPST-NO Output

A 3-position selector switch, located at the lower left corner of the
front panel, determines output operation. In the OFF position, the
control output is forcibly turned OFF regardless of the setting of the
programming tabs. Set to the A UTO position, the output is turned ON
and OFF according to the settings of the programing tabs. In the ON
position, the output is forcibly turned ON regardless of the setting of
the programming tabs.

SPDT Output

When the manual switch at the lower left corner of the front is set to
the OFF position, both load 1 (connected across terminals 4 and 5)
and load 2 (across 5 and 6) are turned OFF.

When it is set to the AUTO position, the output is turned ON and OFF
according to the setting of the programming tabs.

When the manual switch is set to the ON position, load 1 (connected
across terminals 4 and 5) is turned ON and load 2 (across 5 and 6) is
turned OFF.

Output Indicator

The output indicator at the upper left corner of the front panel shows
the status of the output when the manual switch is set to the AUTO
position.

In addition, the output can be manually turned ON or OFF by rotating
the knob clockwise (in the arrow direction). The knob will not tur n
counterclockwise.

Precaution for the H2F-D, -DF Serie s (Synchronous Motor
Models)

Before using the H2F, select the appropriate frequency of your area
by the frequency selector switch provided on the upper part of the
rear panel.

Battery

Remove the battery cover on the rear panel of the H2F, load the pro­vided Battery into the battery box, then turn ON the H2F. Be sure to
load the Battery before using the H2F. If the Battery is not loaded, the
H2F will not work properly.

Press down.

Battery cover

Slide out

Be sure to load the Battery with the correct polar ity. The polarity is
indicated in the battery box. After loading the Battery, be sure to
place the cover on the battery box.

Battery

The Battery is fully charged before shipment. The Battery may lose
its charge while the Battery is stored. Therefore, there is a backup
function that is guaranteed for 180 hours on condition that the Bat­tery is loaded into the H2F and charged continuously for 72 hours. If
the Battery has no charge, the H2F may not operate immediately
after it is turned ON. In that case, continue providing power to the
H2F for three or more minutes before setting the time.

If the H2F is turned ON and OFF frequently, the Battery life will be
greatly reduced. Use the H2F with a continuous supply of power.

The Battery has a life of approximately three years at room tempera­ture. If three years have passed since the Battery was loaded,
replace the Battery as soon as possible with a AAAA-size NiCd
rechargeable battery.

If the H2F is idle over a long time, unload the Battery from the H2F
and store the Battery separately in order to prevent the Battery from
being overly discharged.

Always turn OFF the power supply before replacing the Battery.
Use only the specified Replacement Batter y (Y92S-42). Using any

other battery may result in leakage of battery fluid or battery r upture,
possibly causing equipment damage or injury.

Other Precautions

When connecting to a heater, alwa ys use a thermal switch in the load
circuit.

Do not exceed the specified ranges for vibration and shock.
The H2F is neither waterproof nor oil-proof. Do not use the H2F

where it would be subjected to water or oil.

!WARNING

Do not short the terminals of, disassemble, deform under
pressure, or incinerate the Battery. Doing so may result in
minor injury due to bursting, ignition, or leakage of fluid.

!CAUTION

Do not touch any of the terminals or the back panel while
power is being supplied. Doing so may result in electric
shock. Be sure to mount the terminal cover after wiring.

Before changing times or other settings while power is
being supplied, either turn OFF the power on the load
side or set the output ON/OFF switch to OFF and confirm
the safety of the system. Unexpected operation may
occasionally result.

Tighten the terminal screws to the specified torque.
Loose screws may occasionally result in fire or
malfunction.

Do not allow metal fragments or lead wire scraps to fall
inside the Product. This may occasionally cause electric
shock, fire, or malfunction.

Never disassemble, repair, or modify the Product. This
may occasionally cause electric shock, fire, or
malfunction.

Do not use the Product where flammable or explosive gas
is present. There may occasionally be a risk of explosion
resulting in minor injury.
