DESCRIPTION OF PRODUCT
Haws Corporation Model 8710 Tempered Water Shower Booth is a foam-insulated, aluminum skinned
enclosure with high visibility green chemical and UV resistant polyester-based powder coating. Large
graphics identify the building as an emergency shower/eyewash station and assist in guiding the user to
the double swing doors. The interior is illuminated green during standby and changes to white light when
someone enters the doors, or the shower or eyewash is activated. Optional space heating is available for
user safety and comfort and equipment protection.
Hot water generated via an immersion heater is stored in the water tank. Hot and cold water are mixed
with an engineered blending system to provide tepid water for the specified number of combination
shower/eyewash operations. Typical flow rate of a combination shower/eyewash is 30 GPM. The ASSE
1071 certified blending system is a safe, prepackaged, fully engineered and tested system for blending
large volumes of hot and cold water specifically designed for emergency showers and eyewashes. The
system provides multiple levels of protection to prevent scalding, including a high temperature shutoff valve.
Also included is a pressure relief cold-water bypass that allows full cold flow in the event of a hot water shut
off. There are no electrical components in the blending system.
The 8710 booth includes a Haws®combination shower and eyewash that is protected with a scald valve.
Optional alarms are activated by a flow switch when the shower and/or eyewash are in use. Dry contacts
can be provided for remote alarm notification and/or both visual and audible alarms with a silencing circuit
that auto resets can be provided.

INSTALLATION PROCEDURE
WARNING: DO NOT connect power before supply plumbing. Connections should be performed by
a certified electrician and plumber only.
a. Remove unit from crate.
b. The unit should be secured on a level site, using the supplied brackets and suitable anchoring
devices. Suggested anchoring devices are 3/4” minimum diameter by 1-1/2" minimum length
anchor bolts with washers.
c. If the booth is to be placed over a drain, the drain should be able to handle a flow of 35 GPM;
otherwise, the slab should be made to allow the water to drain out the sides and away from the
booth (see Figure 1). The unit discharges hundreds of gallons of water, which can cause significant
property damage and a potential hazard if not drained properly.
WARNING: Drainage means shall not create an obstruction or tripping hazard.
Figure 1. Example of Slab with Drain Trough
WARNING: Failure to allow water to drain may result in premature failure of booth, voiding of
product warranty, property damage, and hazard to personnel. (See System Drain and Check
Procedure)

HAWS®P/N 0580001081 Rev.1 09/20 Model 8710 Page 7 of 32
d. The connection provided for the water supply is a 1-1/2” NPT union. Water supply lines are required
to be capable of supplying the required pressure and flow to meet ANSI Z358.1. The water supply
line should run for a few minutes prior to connection to eliminate any debris before it enters the
equipment.
e. Connect electrical supply to the Power Distribution Block. It is recommended that a Disconnect
Switch (see Figure 3) is used to safely interrupt the supply for routine maintenance work.
Disconnect switches are available as an option from Haws.
NOTICE: All Power Connections must be made according to local codes and standards using
components which are compliant with the area the unit is being installed in.
Figure 3. Disconnect Switch Junction Box
CAUTION: Do not apply power to the unit until all water connections are made and the tank and
piping are full of water.
f. Once all water and power connections are made, open the supply water inlet valve and fill the
system. While water is flowing into the system, open the emergency shower to facilitate air removal
from the system. After water flows freely from the shower for several minutes, turn the shower off.
Inspect plumbing for leaks and repair as necessary. During transit, some plumbing may have
become loose, allowing water to leak from the threads.
g. The expansion tank should be charged with compressed air to a pressure equal to the water supply
pressure. An air fitting (Schrader valve) is accessible on the top of the expansion tank, under the
plastic cap (see Figure 2).

Figure 2. Top of Expansion Tank
CAUTION: Before turning on the power, close all electrical boxes.
h. At this point the power can be turned on. The tank water must be allowed to heat up before the
blending system will function properly. Heating can take up to 12 hours, depending on supply water
temperature and the size of immersion heater and tank. If included, the area/alarm light may blink
until tank temperature set point is reached.
NOTE: The emergency shower or eyewash (see Figure 4) should be utilized for testing of the blending
system. Refer to the Maintenance, Testing, and Repair section of the TWBS.HF Blending System Manual
document for proper adjustment and operation.
