Smoke Master SMHA HATCH - Installation, operation and maintenance

TECHNICAL DESCRIPTION

Between the hatch and casing is sealing material. Both hatch

and casing have isolation material between metal sheets.

Speciﬁcation

The equipment is an axial fan with casing designed for use as an

exhaust fan in high temperature emergency conditions. The product

is not allowed to be used in normal ventilation. The fan is driven by an

enclosure electric motor classiﬁed to F400(120) in accordance with

EN1201-3. The hatch and fan are integrated to be one certiﬁed unit.

Hatch is opened by 2 electrical motors, which are dimensioned to

cover both snow and wind load. The fan itself should be started 30

seconds after the hatch motors have been started.

The door is also equipped with a mechanical cable opening mecha-

nism. The mechanism is intended for situations where it is desired to

open the door without electricity.

TRANSPORT INSPECTION

Check the fan immediately after you receive it and make sure that it

has not been damaged during transport. If you discover any damage,

get in touch with the transportation company without delay.

• Check the information on the fan rating plate.

• Proper procedures must be followed when transporting the

product.

• Faulty conditions in transporting may result in serious damage on

the product.

TRANSPORT SAFETY

• The transport material is to be selected according to the

packaging and the weight of the product.

• Loading must be carried out as instructed.

INTERMEDIATE STORAGE

If the fan is to be stored before or in between uses, the following

needs to be taken in account:

• Original packaging is to be used.

• If the storage conditions require it, additional protection may be

added.

• The hatch of the product must be closed during the storage.

• During long time storage indoor premises must be used.

TRANSPORT

Smoke Master SMHA HATCH - Installation, operation and maintenance

INSTALLATION

Like smoke hatches, JMHT HATCH can be installed on a roof or a car

park deck in one lift. The product can be mounted directly onto con-

crete or a similar surface, or onto a specially designed base – what is

important is that there is even support across the entire surface. The

fan is fully weather-protected throughout the construction project.

The possibility of condensation must be prevented in smoke extrac-

tion in damp areas by proper installation.

The recommended size for the penetration in the slab is

D + 200mm, and for ease of connection to ducting, the penetration

should preferably be square in shape.

JMHT Hatch allows two alternative connection methods. If the product

is to be duct-mounted, it is delivered with a matching ﬂange at the

bottom. If the fan is meant to draw in air freely from the space below,

the product is delivered with a safety mesh at the bottom. In the latter

case, all that needs to be done to install the unit is to ﬁx it to the roof

structure and connect it to the mains.

The maximum roof slope must be 12°.

Fixing angle irons to the base with at least four 5x40 screws or

with at least four screws to the roof structure:

- to concrete 4-6 psc HILTI HPS-1 6/5x30

- to timber 4-6 pcs wood screws 5x50

- to reinforced concrete 4-6 pcs self-drilling screws 5,5x25

SAFETY REGULATIONS

In case, when the hatch is open and maintenance

work for fan is done, there is a risk of fall through

the fan opening, especially in case, when the fan is

removed from it’s place. The care shall be taken to prevent fall during

the maintenance work.

ELECTRICAL CONNECTIONS

All electrical connections must be wired by authorised personnel only.

The necessary electrical and safety precautions must be taken into

account. The fan is equipped with 2 safety switches, one for the fan

motor and one for the opening motors. Electrical connections shall be

done as shown in picture. The hatch is equipped with switches show-

ing, if the hatch is closed or open.

Motor cable shall be ﬁre proofed (400°C / 2 h) and bushing through the

casing shall be sealed (400°C / 2 h).

The fan motor cable must be a ﬁre resistant

cable. The cable glands in the casing must be

sealed with ﬁre-resistive mass.

It is recommended to use the limit switch only

for the closing information of the hatch. The

starting signal of the motor must come from a

separate control. The starting method for the

fan is direct-on-line starting 30s after the start

of the linear motors.

NOTE! Linear motors must not be exposed to

the control voltage!

PREPARATION

Open the hatch and connect the motor rods to fastenings. Connect the

mains to motors to close the hatch.

HUOM! Varmista luukun avaamisen mahdollistaminen myös ns.

tilapäisen virtalähteen käytön jälkeen (esim. irroita karamoottoreiden

akselit testikäytön jälkeen).

NOTE! Make sure that it is also possible to open the hatch after using a

temporary power supply (eg disconnect linear motor shafts after test

run).

SAFETY CHECKING

Rotate the shaft and check that the impeller can move freely. Make

sure that there are no foreign objects in the fan or in the ducting. Also

check that there is no unusual noise in the fan. Check that the installa-

tion work has been carried out in accordance with the relevant regula-

tions. All necessary protective devices must be installed.

Check also, that there is big enough air ﬂow to compensate fan

air ﬂow. Check, that all other regulations related to ﬁre safety are

followed.

The fan may only be commissioned after all proper procedures have

been followed and all necessary inspections have been carried out.

TEST RUN

Brieﬂy switch on the power supply to the motor to check whether the

fan impeller rotates in the correct direction. If the impeller is rotating in

the correct direction shown with the arrow, the fan may be switched

on. Check that no abnormal mechanical sound and no surging occurs.

COMMISSIONING

Smoke Master SMHA HATCH - Installation, operation and maintenance

WARRANTY

A precondition of the warranty is that regular maintenance has been

carried out. Defects under warranty must immediately be notiﬁed to

the manufacturer or the importer. The warranty does not cover service

work or indirect damages.

MAINTENANCE

BEFORE MAINTENANCE

Switch off the power supply to the fan and hatch motors at the safety

isolating switches. The hatch is staying open, when the safety switch

is turned off from mains. However, make sure, that hatch cannot be

falling down during the maintenance.

INSPECTION INTERVALS

Inspection intervals can be deﬁned by local authorities. If nothing

else is mentioned, the fan shall be tested according to the intervals in

table, but at least once a year. The annual inspection must be done by

authorized persons only. Also follow the separate JMHT fan mainte-

nance instructions.

MAINTENANCE

CHECKING THE MOTOR BEARINGS

The motors are meant to be operated in emergency conditions only.

The motor bearings have to be lubricated in accordance with the

instructions that accompany the motor, latest at 3 years intervals.

Replacements of bearings are to be done in accordance with the

motor manufacturers instructions.

IMPELLER

The impeller shall be clean.

Smoke Master SMHA HATCH - Installation, operation and maintenance

MAINTENANCE

REPLACING THE MOTOR AND THE IMPELLER

The fan will have to be disconnected from the unit before the motor

can be replaced.

SMHA-040,050,080,100-066,100-106

1. Check that the fan motor and hatch-motors are disconnected

from mains.

2. Remove outlet guard.

3. Remove impeller from motor shaft by opening locking screw

from shaft end.

4. Remove impeller from the shaft, take care, that the key is not

dropping down.

5. Motor rotor can be lifted up and bearings can be checked.

SMHA-sizes 100-180 and all size 125 versions

1. Remove complete fan and lift it outside the casing for

maintenance.

2. Follow instructions of JMHT for maintenance.

FINAL INSPECTION

Check that:

• The impeller is mounted for the correct direction of rotation.

• All screws and nuts have been tightened.

• No foreign objects have been left in the fan or in the ducting.

• The mechanical opening of the hatch works.

The mechanical opening of the hatch is intended for situations where

the door has to be opened without electrical current for one reason or

another.

The door can be opened mechanically by pulling the wires under the

hatch. There are two wires and they are located on both sides of the

linear motors. Pulling on the wire requires some force, so you have to

use an aid, such as an iron pipe (see picture).

After the mechanical opening, reattach the linear motor shafts to the

mounting lugs and make sure that the cover seals are intact.
