OPERATING MANUAL
(Continued on back.)
INTRODUCTION:
The HM-630 Moisture Room Control Panel is designed to
maintain a constant temperature and humidity for concrete
sample curing rooms. The panel consists of a temperature
water mixing valve controlled by a digital controller and a
thermocouple / sealed sensor. The control panel is mounted
on a PVC backboard that is 30” long and 20” high. It is
mounted on the wall outside the curing room with the sensor
mounted on the wall about 4 ft. high inside the curing room.
The panel is designed to work as a
closed loop system in
conjunction with spray heads (1.5 gph) strategically placed in
the curing room. Hot and cold water is fed into ½” connections
at the bottom of the panel. The water is regulated and exits
through a ½” discharge fitting at the top of the panel. This
outlet is piped directly into the curing room and feeds a
closed loop piping arrangement with the spray heads. The
panel has a 3-prong cord that is designed to be plugged into a
120V/60Hz/15A GFCI protected outlet. The panel is governed
by a normally closed solenoid valve and an on/off switch
mounted on the front of the panel. There also is a manually
controlled by-pass valve in the event of a power outage. The
mixing valve also has a manual override if the valve must be
adjusted in the event the AC power goes out.
The panel is designed to maintain a constant temperature at
100% humidity by the temperature controlled water running
constantly into the curing room. Please refer to the Installation
and Operating Instructions for a complete guide in proper
installation and set-up of the Moisture Room Control Panel.
INSTALLATION & OPERATION:
This Control Panel is designed and pre-assembled for easy
installation. The unit must be installed on the outside of the
moisture room, indoors, and protected from water.
1. Fasten the control panel to the outside wall of your
moisture room near the door approximately four feet up
from the floor and within five feet of a 120V/60Hz/15A
GFIC outlet. Installation location should make the panel
easily reachable and convenient to read the controls.
Secure with large screws.

2. Run the hot and cold water supply lines to the ½” pipe
fittings at the bottom of the unit. The left one is the “Hot”
and the right one is the “Cold”.
NOTE: The SharkBite
®
Connection System Is to be used
with COPPER or CPVC tubing ONLY!!
To Connect a Joint:
• Mark 7/8” down the tube.
• Push the tube firmly until it reaches the mark on tube.
To Disconnect a Joint:
• Push on the plastic release collar with a 5/8” open end
wrench and pull.
3. Make an appropriate hole through wall, and run the
½” waterline up and into your spray head system
inside moisture room. Spray heads should be rated
approximately 1.5 gallon per hour each.
4. Mount the Temperature Sensor inside the moisture room
approximately half way between the ceiling and the floor.
Fill the hole with waterproof sealant. DO NOT extend the
length of the sensor wire.
