Installing a Transmitter on a Regulator
To install the TRT on the Regulator First Stage:
Remove the existing pressure gauge and high pressure hose, or the high pressure port plug from the port marked HP using proper size hex key.
Lightly lubricate the o-ring and threads of the transmitter fitting with a halocarbon based lubricant such as Christo-Lube MCG111 (provided in TUSA Battery kits).
Thread the transmitter clockwise by hand into the regulator's hp port and tighten until secure with a 5/8" open-end wrench.
Attach the regulator first stage to a full Scuba tank and pressurize by slowly opening the tank valve, listening for any indication of air leaking around the fitting.
If air leakage is present, DO NOT use, take the complete regulator assembly to an authorized TUSA dealer for inspection and service.
