1.0 GENERAL

1.1 IMPORTANT SAFEGUARDS AND WARNINGS

Prior to installation and use of this product, the following WARNINGS should be
observed.

1. Installation and servicing should only be done by qualified service personnel
and conform to all local codes.

2. Unless the unit is specifically marked as a NEMA Type 3, 3R, 3S, 4, 4X, 6, or
6P enclosure, it is designed for indoor use only and it must not be installed
where exposed to rain and moisture.

3. Only use replacement parts recommended by Pelco.

4. After replacement/repair of this unit’s electrical components, conduct a resis­tance measurement between line and exposed parts to verify the exposed
parts have not been connected to line circuitry.

The product and/or manual may bear the following marks:

This symbol indicates that dangerous voltage constituting a
risk of electric shock is present within this unit.

This symbol indicates that there are important operating and
maintenance instructions in the literature accompanying this
unit.

CAUTION:

RISK OF

ELECTRIC SHOCK.

DO NOT OPEN.

TO REDUCE THE RISK OF ELECTRICAL SHOCK,

DO NOT REMOVE COVER. NO USER-

SERVICEABLE PARTS INSIDE. REFER SERVICING

TO QUALIFIED SERVICE PERSONNEL.

CAUTION:

Please thoroughly familiarize yourself with the information

in this manual prior to installation and operation.

2.0 DESCRIPTION

The information in this manual covers the installation and operation of the following
kits for the EH5700/EHS700L Series environmental enclosures:

BK57-1 Blower kit, 120 VAC, 15 watts

BK57-2 Blower kit, 24 VAC, 10 watts

BK57-3 Blower kit, 230 VAC, 15 watts

HK57-1 Heater kit, 120 VAC, 100 watts

HK57-2 Heater kit, 24 VAC, 40 watts

HK57-3 Heater kit, 230 VAC, 100 watts

O/I-PCB Circuit board with thermostats

WD57-1 Window defroster kit, 120 VAC, 30 watts

WD57-2 Window defroster kit, 24 VAC, 30 watts

WD57-3 Window defroster kit, 230 VAC, 30 watts

The O/I-PCB circuit board is required for thermostatic control of the heaters and
defroster. The O/I-PCB is optional with the blower kits; without the O/I-PCB, the
blower will operate continuously.

3.0 BLOWER KIT INSTALLATION

This section provides instructions for installing the BK57-1. BK57-2. and BK57-3
blower kits.

For the following instructions, refer to Figure 1. Table B lists the parts shown in Figure 1.

1. Turn off power to the enclosure.

2. Unlatch and raise the enclosure lid. The gas spring will hold the lid in place
when it is fully opened.

NOTE:

If you are using your enclo­sure in a marine or high-moisture
environment, skip steps 4-7. The vent
covers must be left in place.

3. Remove the camera and sled.

4. Remove the vent grill inside the enclosure at the rear of the unit.

5. On the bottom of the enclosure, remove the two vent covers.

6. Place the two foam filters in the vent grill.

7. Install the vent grill in the bottom of the enclosure at the front of the unit.

8. If you are installing your enclosure in a marine or high-moisture environment,
modify the fan assembly as follows:

a. Remove the four Allen screws that secure the fan to the fan plate.

b. Turn the fan around so that it will blow toward the viewing window (the

arrow on the fan points toward the fan plate).

c. Reinstall the fan on the fan plate.

9. Install the fan plate and fan in the enclosure with the hardware that is supplied:

a. Slip the fan wires into the slot at the bottom of the fan plate so that the

white plug is on the opposite side of the fan plate from the fan.

b. Place the fan plate and fan into the enclosure with the fan facing toward

the rear of the enclosure and the fan plate against the camera sled track.

c. Attach the top center of the fan plate to the enclosure with the standoff, a

screw, lock washers, and flat washers.

d. Attach the bottom right and bottom left sides of the fan plate to the cam-

era sled track with screws and lock washers.

10. Continuous Duty Operation Only - If your enclosure does not have the O/I­PCB circuit board for thermostatic control, complete the installation as follows:

a. Connect the fan to power. The BK57-1 and BK57-3 fans use 15 watts of

power. The BK57-2 uses 10 watts. If you are using 24 VAC, refer to Table
A to determine the size of wire to use.

b. Reinstall the camera and sled.

c. Close the enclosure lid.

d. Turn on power.

Table A. 24 VAC Wiring Distances

The following are the recommended maximum distances for 24 VAC applications
and are calculated with a 10-percent voltage drop. (Ten percent is generally the
maximum allowable voltage drop for AC-powered devices.)

EXAMPLE:

An enclosure that re­quires 80 vA and is installed 35 feet
(10 m) from the transformer would
require a minimum wire gauge of 20
Awg.

NOTE:

Distances are calculated in
feet; values in parentheses are
meters.
