IMPORTANT

Read this installation manual completely to ensure proper installation, then file it with the owner or

maintenance department. Compliance and conformity to drain requirements and other local codes and

supply to the

and a minimum fill flow rate of 15 GPM for the

ordinances is the responsibility of the installer.

Separate parts from packaging and make sure all parts are accounted for before discarding any
packaging material. If any parts are missing, do not begin installation until missing parts are obtained.

Flush the water supply lines before beginning installation and after installation is complete. Test the unit
for leaks and adequate water flow. For ANSI Z358.1 compliance, the main water
emergency fixture s hould be “ON” at all times. Prov isions should be made to prevent u nauthorized
shutoff.

The ANSI Z358.1 stand ard requires a 20 GPM flow rate for the shower and a 3 GPM flow rat e for the
optional Eye/Face Wash of flushing fluid f or 15 continuous minutes. Ha ws Model 8740 self-contained
shower requires a minimum fill pressure of 20 PSI
shower only or 20 GPM for shower and optional Eye/Face Wash combination at the automatic refill
connection to meet this requirement. Flushing fluid should be tepid per ANSI Z358.1. Haws Model 8740
should be installed in an indoor area that has an ambient temperature between 60°F and 100°F to meet
this tepid water requirement.

The tank water level should be checked weekly to ensure that the tank is full. For ANSI Z358.1
compliance, the automatic refill connection must be connected to an adequate potable water source.

This unit discharges water to the floor. It is recommended that this unit be installed in an area that
has adequate floor drainage. Failure to do so may result in major property damage.

DESCRIPTION OF PRODUCT

Haws Corporation Model 8740 non-electric, self-contained overhead tank shower and optional Model
874301S Eye/Face Wash is des igne d for us e in in door ar eas where the temper ature is norm ally between
60°F and 100°F. The 330-gallon high density polyethylene (HDPE) overhead tank is discharged by gravity
upon shower or optional Eye/Fac e Wash activation. The unit is equipped with a 1-1/4” NPT inlet water
connection and float valve for automatic refill.

The unit is designed to m eet ANSI Z358.1 s tandards for flow and duration if it is connected to a suit able
permanent potable water source. Haws Model 8740 self-contained shower requires a minimum fill pressure
of 20 PSI and a minimum fill flow rat e of 15 GPM for the sho wer only or 2 0 GPM for shower and optional
Eye/Face Wash combination at the autom atic r efill con nection to m eet this require m ent. Water should be
tepid per ANSI Z358.1. Haws Model 8740 should be installed in an indoor area that has an ambient
temperature between 60°F and 100°F to meet this tepid water requirement.

The optional Model 874301S Eye/Face W ash available for this unit uti lizes Haws Axion MSR (Medically
Superior Response®) eyewash design. The AXION MSR Eye/Face Wash uses an inverted stream design
which sweeps chem ical and particulate contaminants away from the vulnerable nasal ca vity, consistent
with medical irrigation protocols.

Although optional, the Model 9084 is recommended for use with the Mod el 8740. T he Model 9084 is an
immersible Cleansin g Stick that gives continual protection against path ogenic bacteria for water storage
systems. It balances the PH of the water preventing the build-up of bio-film, scale, and corrosion for up to
3 years with proper usage.

MODEL 8740 ASSEMBLY & INSTALLATION PROCEDURE

1. Transport the p allet ized uni t to the install ation po int via f o rk lift, ensuring the forks are ins er ted through
the shipping pallet.

2. The installation area should be located indoors on a level floor capable supporting up to 4,000lbs spread
across the four Frame Feet. Suitable concrete flooring is preferred. If unit is to be placed over a drain,
the drain should be able to handle a flow of 35 GPM; otherwise, the slab should allow the water to drain
away from the unit.

3. Confirm there is suitable available vertical space where the unit is to be installed . T he unit r equ ires a
minimum of 13ft vertical space for installation, 13.5ft of vertical space for assembly, and 14.5ft of vertical
space to insert or remove the optional Model 9084 Cleansing Stick if utilized.

4. Remove the plastic wrap packaging around the palletized unit.

5. Cut the three (3) steel bands that st rap the unit to the wooden pal let as shown in Figure 2. DO NOT
cut the steel bands on top of the tank ass em bly (th ese 4 bands retain the tank on the tank fram e and
will not be removed).

Cut and remove
three steel bands
that strap the unit

to the wooden

pallet ONLY.

Figure 2. Removing 3 Steel Bands

6. Use a forklift to lift the Tank Assembly (Item #1) from the palletized unit, using the fork slots on the Tank
Assembly, and set the Tank Assembly aside.

7. Remove box of com ponents from the pallet and rem ove components from the box. Next, remove
shipping screws/washers holding frame components to pallet. Discard shipping/screws. Place all
components in a secure area until needed.

CONNECTING THE MODEL 8740 AUTOM ATIC REFILL VALVE TO A POTABLE WATER SOURC E

The Model 8740 is equ ippe d with a 1-1/ 4” m ale NPT fitting (Figure 31) on t he fill pipe located on the b ack
of the unit. This pipe should be connected to a permanent potable water source. To meet the ANSI Z358.1
standard for flow a nd dur ati on, the unit requires a minim um f ill pr es sur e of 20 PSI and a m inimum fill flow
rate of 15 GPM for the shower only or 20 GPM for shower and optional Eye/Face Wash combination at the
automatic refill connection. Pressure should not exceed 60 PSIG. Use a pressure reducing device if
necessary.

FILLING THE MODEL 8740 TANK WITH POTABLE WATER

1. Connect a suitable sourc e of potabl e water to the inlet connection on the back of the unit as shown in
Figure 31.

“ON” at all times. Provisions should be made to prevent unauthorized shutoff. Refer to your facility’s lockout
tagout procedure.

2. Ensure the shower (and Eye/Face Wash if equipped) valves are closed.

3. Turn on the water source and monitor the water level in the tank via the slot in the front tank panel.

4. If little or no water enters the tank, confirm the shipping protection strap on the float valve was properly
removed during assembly.

5. Allow the tank to fill. The float valve in th e tank wil l automatically shut off the flow as the water level
approaches the top of the tank. The tank should not fill completely to the top or exit the vent on the top
of the tank.

6. Check the inlet piping, tank, and shower piping for leaks and address as required.

7. If the optional Eye/Face Wash assembly has been instal led, chec k for leak age in the hose and piping
to the unit before and after activating the Eye/Face Wash.

TESTING THE INSTALLATION

1. With the tank full of water, pull the s hower activa tion handle. It is recomm ended to stand be hind the
unit to avoid drenching of the shower.

2. Confirm the handle pulls smoothly, but firmly both on and off .

3. Confirm the shower flows freely and shuts off completely. If water does not flow or flow freely, confirm
the tank ball valve at the tank outlet is fully open (handle parallel to pipe).

IMPORTANT!! For ANSI Z358.1 compliance, the m ain water supp ly to the em ergency fixture sho uld be
“ON” at all times. Provisions should be made to prevent unauthorized shutoff. Refer to your facility’s lockout
tagout procedure.

4. If the optional Eye/Face Wash assembly has been installed, push the Eye/Face Wash activation flag.

5. Confirm the Eye/Face Wash assembly actuation flag moves smoothly on and off.

6. Confirm the Eye/Face Wash flows freely and shuts off completely.

7. Confirm the automatic refill functions properly and that the tank is refilled.
